The Bronze Age. Dusk in the eastern Mediterranean (Westbrook 1995). The people on the island of Thera felt something frightening and cataclysmic in the air (Ibid.). They were preparing to abandon their home island (Ibid.). They had filled storage jars with wine, olive and wheat as if one day they would have come back to reclaim them (Ibid.). They carefully closed each lid (Ibid.). They also hid some valuables in their houses’ basements or under door frames (Mitchell 2011). Yet, their most precious possessions, like gold and jewels, they took with them (Westbrook 1995). They carefully sealed their houses as if protecting them from thieves and rushed to their boats (Mitchell 2011). What those people felt was the earth itself trembling beneath them but they had already survived similar earthquakes in the past (Westbrook 1995). That time, however, it was not a mere earthquake (Ibid.). Those people were to never return to their olive, wine and idyllic life they had depicted in their frescoes (Ibid.). They would have simply fled into the night and into the sea (Ibid.).
In the Mediterranean region, in the wide expense of the Blue Aegean Sea, a group of islands stands out in a Greek archipelago (Masjum 2006). They are thrown north of Crete, with a huge caldera at their center (Wengler 2009). The archipelago’s dark and brooding nature appears in contrast to the white limestone and pristine marble of the buildings (Masjum 2006). This islands are collectively known today as Santorini (Ibid.). The terraced landscape and rich volcanic soil make the them ideal for vineyards (History Channel 1980s). For this reason, Santorini is home to some of the finest wines in the world (Ibid.). But while tourists travel to Santorini for sun and the island’s quaint village life, archaeologists keep searching there for more clues about the destruction of the Minoan empire (Ibid.).
For years, teams of various scientists, each specialized in a particular field, have joined their forces to solve the mystery (Lilley 2006). They are still finding new evidence of a dreadful disaster that overwhelmed Europe’s first civilisation (Ibid.) ‘Did their terrible fate create the myth of Atlantis, the continent-city that drowned?’, speculates the archaeologist, Dr Sandy McGillivray (Ibid.). ‘They worshiped the sea and the sea [eventually] turned against them’ (Ibid.)
More than two thousand years ago, the Greek historian Plato wrote about Atlantis, the fabulous civilization that had been swallowed by the sea but no one has been able to trace the origins of Plato’s story yet (Lilley 2006). Appearing evidence from the island of Crete led some archaeologists to speculate that the Atlantis legend was in fact created in the Mediterranean (Ibid.). Is the legendary destruction of Atlantis just a folk memory of what happened to the Minoans, who flourished on Crete in the Bronze Age, over two thousand years before Plato? (Ibid.)
Atlantis was mentioned in Plato’s works Timaeus and Critias, in the fourth century BC. (Westbrook 1995; Harpur, Westwood 1997:18). The great Athenian philosopher claimed the story had originally come from Egypt (Westbrook 1995; Harpur, Westwood 1997:20). It was handed down to him from an Athenian lawmaker, Solon, who had in turn heard it from Egyptian priests from Sais, the capital of Lower Egypt (Ibid.). Solon, and after him Plato, both claimed these were facts, no fiction (Westbrook 1995; Harpur, Westwood 1997:20). According to their accounts, a highly advanced civilization would have developed on the island of Atlantis (Westbrook 1995; Harpur, Westwood 1997:18-21).
In the Bronze Age, the Greek islands were in fact home to an advanced civilization, competing for cultural, artistic and commercial influences in the region, even with the pharaohs of Egypt (Mitchell 2011). These were the Minoans (Ibid.). Centuries before the Greek built the Parthenon, Minoan artists recorded their achievements through exquisite carvings and stunning frescoes (Lilley 2006). They were the first Europeans to use writing but at the height of their powers they were wiped from the pages of history (Ibid.). Their disappearance is still one of the ancient world’s greatest mysteries (Ibid.). Some think the Minoans were slaughtered by conquers from overseas (Ibid.). Others claim that the cataclysmic eruption destroyed them (Ibid).
Apart from the legend of Atlantis, there are also other famous stories passionately haunting human imagination. Until the twentieth century, the Minoans had been the mysterious people known only from Greek myths about hybrid monsters and human sacrifice (Lilley 2006). The archaeologist, Dr Sandy McGillivray has been studying Minoan culture on Crete for twenty-five years (Ibid.). He has explored ancient caves in the centre of the island (Ibid.). For hundreds of years, people have believed their winding corridors were actually the Cretan labyrinth, which was the home of legendary Minotaur (Ibid.). Greek myths describe the beast as a feeding on human flesh, half-bull and half-human creature, who was imprisoned in the subterranean chambers by King Minos (Ibid.). According to the myth, the Minotaur had a very particular taste (Ibid.). He liked to consume its human prey alive (Ibid.). ‘To keep a Minotaur fed, Minos executed the tribute of seven maids and seven youths from the Athenians and once they entered the labyrinth, they never left it’, recounts Dr Sandy McGillivray (Ibid.). The myth suggests that Minoans practiced human sacrifice and were even cannibals (Ibid.). Or was this simply a propaganda generated by Greek fears of a powerful people? (Ibid.).
When the explosion of Thera occurred, the Minoan empire must have been at its highest (Westbrook 1995). However, despite their power and remarkable achievements, the Minoans disappeared after 1500 BC (Lilley 2006). Their fate is still a mystery (Ibid.). Were they wiped out by ancient Greek invaders, described by Homer in his epic poems about the Trojan war? (Ibid.). Or was it a catastrophic natural event, like the one that supposedly destroyed the Atlantis? (Ibid.).
In 1900, the British archaeologist Arthur Evans started excavating at Knossos in northern Crete, near the modern capital of the island, Heraklion (History Channel 1980s; Lilley 2006). The whole western world was astonished by his discovery (Lilley 2006). Evans devoted forty years of his life to this endeavour, for which he was eventually knighted (History Channel 1980s).
After the excavations started, it shortly turned out that the archaeologist had come across the capital of the highly advanced civilisation of the Bronze Age (Lilley 2006). Whilst the ancient Europeans were living as barbarian warriors, building clay huts, Cretans were creating monumental architecture and living in overwhelming luxury (History Channel 1980s; Lilley 2006; Mitchell 2011). Men in Knossos must have moved about proudly and confidently (History Channel 1980s). Women were attired elegantly and glamorously (Ibid.). Evans exhumed in Knossos a huge architectural complex, he soon called a palace (History Channel 1980s; (Lilley 2006). It was a complex of buildings of the size of four football fields consisting of one thousand and three hundred courtyards, halls, passageways and rooms (History Channel 1980s; Mitchell 2011). All of them belonged to one single building, which was the heartbeat of the Minoan empire (History Channel 1980s). The palace was approached by massive entrance portals, leading deep inside its subterranean complex (Ibid.). Above the surface, the palace was two to three storeys high and built of cut stone (Ibid.). The walls were decorated with serene motifs of flowers and animals (Ibid.). War was not glorified there (Ibid.).
The architecture was so bewildering that Evans was convinced that he had found the Minotaur’s labyrinth, incorporated into the King Minos’ royal residence (History Channel 1980s). He found there marble walls and alabaster floors, which had been protected by the earth for millennia (Ibid.). In the lavishly decorated private chambers of the priest-king, as Evans assumed, a bathtub was even found (Ibid.). Staircases functioned as ingenuously designed air-conditioners (Ibid.). Light shafts provided subdued lighting (Ibid.). Below the floors, complicated drainage conduits have been built for bathrooms and, first in Europe, flush toilets (Ibid.). Even rainwater, which was collected in the open courtyards of the palace, passed through a special system of drains (Ibid.).
In the storehouses there were as many as four hundred storage vats for wine, oil, grains and honey (History Channel 1980s). The Minoans’ capital itself was a masterpiece of contemporary town planning, with its buildings being connected by Europe’s first paved roads (Lilley 2006). Surrounding the palace, there was a town with a population of more than forty thousand inhabitants (Ibid.).
Based on what Evans found, archaeologists have built a more accurate picture of what this once great empire looked like (History Channel 1980s). Modern technology offers an impression of extraordinary splendour of the civilization around the whole Crete; ceremonial buildings, holy places, storehouses and workshops were once grouped around large central courtyards (Ibid.). Successively, archaeologists have discovered similar Minoan settlements with the so-called palaces throughout Crete and far beyond it (Lilley 2006). Among them, Knossos is believed to have been the most significant.
The Minoans were the contemporaries of the mighty ancient Egyptians, with a language of their own and a distinctive culture, widely revered by others (Masjum 2006). Highly cultured and civilized, the Minoans held much promise as a people (Ibid.). It was their culture that provided the seed of Greek civilization a thousand years later (Ibid.). They had an advanced state of bureaucracy and organization (Ibid.). The Minoans were equally skilled craftsmen capable of producing exquisite treasures and sophisticated objects of art (Lilley 2006). Their pottery was known throughout the contemporary world for its outstanding beauty and craftsmanship (History Channel 1980s). Its distinctive geometric patterns and naturalistic imagery were prized even by the pharaohs (Ibid.).
Merchants, not warriors
The source of Minoan wealth was their rule at sea (Mitchell 2011). They were peace-loving traders who placed strong emphasis on commerce and not war (Masjum 2006).
A geologist, Jelle Zeilinga de Boer, says that the Minoans created a commercial empire (Masjum 2006). ‘They did not have any defensive walls or anything to protect themselves because they had the [powerful fleet], and they were known in the entire eastern Mediterranean as traders’ (Ibid.). Also artistic influences of the Minoans were far-reaching (Wengler 2009). Minoan pottery and other various artifacts carried by their ships have been found from Spain to Mesopotamia (Lilley 2006). Their distinguished artistic style and motifs, flourished in frescoes also in foreign palaces of Mycenaeans, Egyptians and even Canaanites, such as Tel Kabri, in modern day Israel (Cline 2013). In the Egyptian city of Avaris (also Awaris), in the north-eastern region of the Nile Delta, the Egyptologist, Prof. Manfred Bietak has found a Minoan fresco, dated back to the sixteenth century BC. (Wengler 2009). It represents a recurring theme of the Minoan iconography, especially on Crete, which is a bull-leaping (Ibid.). Bietak claims that the fresco must have been painted by a Minoan artist, probably living and working in Avaris and decorating an Egyptian palace in a typical Minoan style (Ibid.). At the time of the Eighteenth Dynasty, the artistic influence of the Minoans on Egyptian art became highly noticeable (Ibid.). The presence of Minoan frescoes in the Nile Delta is further evidence of close contacts between these two worlds: Egyptian and Minoan (Ibid.).
In ancient times, the Minoans traded with the peoples of the Aegean and were amongst the first to sail to distant foreign lands (History Channel 1980s). After the British author, Gavin Menzies (2011), their boats voyaged westwards through the Pillars of Hercules to finally reach not only the British Isles but even northern America. Although scholars have rejected such theories as pseudohistory, all of them agree that the Minoan representatives surely travelled to the Near East and up the River Nile to the legendary city of Thebes, in Egypt (History Channel 1980s; Cline 2013). The palaces in their homeland of Crete, in Knossos, Phaistos and Malia were on a smaller scale than in Egypt but archaeologists claim to have observed in Cretan monumental architecture, structural designs similar to the temples dedicated to Egyptian gods, like Osiris, Isis or Hathor (History Channel 1980s). As Diodorus of Sicily writes in the first century BC. (Bibliotheca historica, Book I, 61), the architect of the labyrinth in Knossos, Dedalus, had first seen such an edifice in Egypt and designed a similar one for King Minos (Santarcangeli 1982:85). Although the Egyptian one was more monumental than the Cretan, it apparently served as its prototype (Ibid.:85).
On the other side, the Minoans’ maritime empire was so vast that it even rivalled the ancient Egyptians (Lilley 2006; Mitchell 2011). Nonetheless, the islanders must have been popular and respected in ancient Egypt (Ibid.), particularly because they did not sail with warships on buccaneering raids but as peaceful merchants (History Channel 1980s). Apart from mutual trading, as some scholars underline, there may have also been other Egyptian – Minoan relations, especially in the context of religion and ritual (Santarcangeli 1982:73-85). Yet, all of the sudden, all records of the Minoans came to an abrupt end in the papyrus texts of the Egyptian scribes. Why? (History Channel 1980s).
With time, the Minoans colonized Aegean islands also in the parts of mainland Turkey (Lilley 2006). Consequently, their powerful fleet could significantly control the Mediterranean’s trade routes (Mitchell 2011). At their intersection between Europe, Asia and Africa was Crete, the strategic centre of Minoan power (Ibid.). One hundred and twelve kilometres north lay the island of Thera, known today as the group of Santorini islands (Ibid.).
The island of Santorini may provide a clue to solving the Minoan disappearance from history (Lilley 2006). The wild scenery and jagged cliffs draw countless tourists but they do not realize that this is in fact a highly explosive volcano (Ibid.). Nor did the colony of Minoans, who lived on Santorini in the Bronze Age and had built their town on the most dangerous island in Eurasia (Ibid.). At that time, the island was known as Thera. Its crescent shape testifies to a violent volcanic past (History Channel 1980s). Its harbour is now a gigantic caldera, so deep that no ship’s anchor can touch the bottom (Ibid.). In the middle, a volcanic dome rises out of the sea (Ibid.). Today it is an awesome monument to the fourth largest eruption in the last twenty thousand years (Ibid.). It was a cataclysm that some believed led the Minoan civilization to its final end (Ibid.).
In 1967, archaeologists discovered the Minoan town of Akrotiri, located on the southern coast of Santorini (History Channel 1980s). It was buried on the slopes of the vast volcano crater (Lilley 2006). Traces of Thera’s wealth can be seen in the ruins of this town (Mitchell 2011). Kitchens and storehouses offered a glimpse of people’s daily life (History Channel 1980s). At the moment they were found, storage jars still contained green kernels and olive pips (Ibid). Along the streets stood buildings whose walls were richly decorated with sophisticated frescoes (Mitchell 2011).
Prof. Floyd McCoy, a geo-archaeologist, pays attention to the way Akrotiri’s inhabitants may have celebrated their life, which is well reflected in Minoan art. ‘If you take a look at the wall paintings that have been discovered [there], they are portraying their landscape. This is a happy landscape: animal bouncing around and [girls] picking saffron’, he says (Lilley 2006). ‘They [are] showing a nice lifestyle, comfortable one. It’s a pity it was all destroyed’ (Ibid.). People living on Thera, like the Cretans, built a highly advanced society, provided with such facilities as the world’s first home toilets combined with an underground sewage system (Mitchell 2011). For such a luxury most Europeans waited another two thousand years (Ibid.).
Island cursed by gods
In the rubble of the ancient town, scientists have found clues, which suggest that Thera eruption may have coincided with the downfall of the Minoan civilization (History Channel 1980s).
Gradually the buried city began to divulge its secrets (History Channel 1980s). However, working among the crumbling walls was dangerous and the man who first discovered Akrotiri, the veteran Greek archaeologist Spyridon Marinatos (1901-1974), was killed by falling rocks and buried in his town (Ibid.). His daughter, Nanno Marinatos, is carrying on his work (Ibid.). She says that most archaeologists agree that the Minoans established a theocratic empire of the seas (Ibid.). Still they do not know what their ruling class was like (Ibid.). Marinatos thinks that its representatives were priests and they claimed their special connections with a deity (Ibid.). Minoan priestesses apparently had the greatest power of all (Mitchell 2011).
As Marinatos claims, Minoan priests usually appeared in front of the public dressed as deities, which is well defined by the preserved frescoes (History Channel 1980s). Indeed, the Minoan art represents the mysterious world, where powerful priestesses performed strange and dangerous rituals (Mitchell 2011). Their task as it seems was to communicate with the gods, often through complex rituals in which saffron served as a hallucinogen (Ibid.). Like all ancient civilizations, the Minoans believed that their gods were present everywhere (Ibid.).
Deity was responsible for every natural phenomenon, from the birth of a child to earthquakes, from the seas to the mountain peaks (Mitchell 2011). And the ancient peoples seemed to treat them as flesh and blood figures. Minoan gods were not considered gentle and merciful beings, but rather impulsive and often vindictive (Ibid.). To obtain the favour of the gods sacrifices were made to them and rituals were a way for priests to know their desires (Ibid.). In many houses in the town, rich and colourful paintings reveal images of the Minoan spiritual life: priestesses paying homage to their gods, maids and youths depicted at different stages of their initiation (History Channel 1980s). Even the young man with his abundant catch of fish, archaeologists believe may be on his way to the sacrificial altar (Ibid.). But with time, the Minoan belief system had to begin to break down (History Channel 1980s; Mitchell 2011). It was due to the geological forces that contributed to the destruction of Thera and this glittering world sank in the chaos of the powers of nature (Ibid.).
Earth-shaker is getting furious
In the second millennium BC., Akrotiri was shaken by a violent earthquake but this was merely the beginning of the natural disaster and subsequently the collapse of the entire Minoan civilization (History Channel 1980s; Mitchell 2011). One of the most powerful Minoan gods was called ‘earth-shaker, also identified with Poseidon (Harpur, Westwood 1997:18; Mitchell 2011). As a deity, he was responsible for sea powers and earthquakes and for this reason he was particularly frightening (Ibid.). Structural damage discovered on Thera shows that just before the volcanic eruption there was an earthquake with magnitudes exceeding seven degrees on the Richter scale (0-9) (Mitchell 2011).
The buildings on Thera had been designed to withstand weaker shocks, which usually happened in that region (Mitchell 2011). The houses were therefore strengthened by a skeleton made of thick, wooden logs (Ibid.) However, that earthquake was strong enough to smash a stone staircase, as it is visible in ancient Akrotiri, and triggered a series of fatal events for the inhabitants of Thera (Ibid.).
Heralds of the coming disaster
Yet before the deciding earthquake came, the great eruption announced itself slowly and gradually (Wengler 2009). As the black mountain, the volcano was slowly coming to life (Ibid.). One of the first signals of volcano activity were hydrothermal explosions caused by heated groundwaters (Mitchell 2011). Boiling fountains of steam bursting from the sea were accompanied by the first tremors shaking the island (Wengler 2009). Sea quakes caused giant waves to form (Ibid.). These were the heralds of the coming disaster a few months ahead (Ibid.) A Minoan wall painting from the island of Santorini represents a giant wave and drowning people beneath it (Ibid.). Is this a portrayal of the events just before the eruption? (Ibid).
For over seventeen thousand years, the magma reservoir beneath the island’s surface was closed but recurring tremors kept deepening cracks and lava began to rise (Mitchell 2011). The rising magma was accompanied by the larger release of sulphurous vapours and other toxic gases (Ibid.). It was another sinister harbinger of the approaching eruption (Ibid.). Foul-smelling sulphurous vapours emerged and spread (Wengler 2009).
Certainly, for the inhabitants of the island it became a race against time (Wengler 2009). According to archaeological research, the damage after the final earthquake was so severe that residents of Akrotiri had to leave their weakened homes and probably moved to temporary camps, in the hope that they would be able to return to their town soon (Mitchell 2011). “There is evidence [that] people [even] started to repair the damage, but before repairs were complete, another set of quakes hit the town. It appears people abandoned it then and left fairly quickly, as many belongings were [found in Akrotiri]” (Jensen 2018). Undoubtedly, the residents had tried to save whatever they could (Wengler 2009). Just before the eruption, they managed to gather food and water supply and other domestic equipment, but eventually, food jars and the beds tied together and ready to go had to be left behind (Ibid.). The excavations at Akrotiri has showed that while some houses were almost completely emptied before eruption (Ibid.), in others, precious belongings were found safely under the bed or wooden frame (Mitchell 2011). Houses’ doors were shut tight (Ibid.). When the mountain belched hot volcanic ash, for the Minoan islanders it was high time to leave their island (Wengler 2009). Experts believe the population got off Thera just in time; unlike in Pompeii, no trace of human remains have ever been found in Akrotiri (Wengler 2009; Jensen 2018). Yet nobody knows where they sailed to take refuge (Wengler 2009).
Stages of eruption
‘And suddenly [the volcano] exploded’, says Prof. Floyd McCoy, a geo-archaeologist (Lilley 2006). Thera was erupting (Ibid.). The vast volcano blasted ash, gas and rock up to into the stratosphere (Ibid.).
On Santorini, a team of geologists, volcanologists, botanists, archaeologists and physicists has regularly studied the site of the disaster (Wengler 2009). Evidence of the volcano power is all around the island (Lilley 2006; Mitchell 2011). There are deposits that are more than sixty metres deep in places (Lilley 2006). The scientists have made an attempt to reconstruct different stages of the Thera’s eruption (Ibid.). ‘There, in that cliffs face,’ Prof. Floyd McCoy points to the multicoloured high rock face on Santorini, ‘[there are] all four [visible] layers representing the four major faces of this huge dramatic eruption’ (Ibid.).
Following the final earthquake, the pressure of magma burst the rock, which for thousands of years had clogged the volcano funnel (Mitchell 2011). It was only a preview of an impending explosion (Ibid.). The volcano was only clearing its throat (Ibid.).
Earlier generations had already seen similar but minor eruptions and recognized them as signs from the gods (Mitchell 2011). These were signs whose understanding was the task of the priests (Ibid.). For the Minoans, there was no better way to satisfy threatening and unpredictable gods than through sacrifice (Ibid.). They performed such rituals in sanctuaries, high in the mountains, where they were physically closest to the gods (Ibid.). Twenty-three such places have been discovered in Crete itself, and in them the remains of thousands of clay figurines (Ibid.) Clay parts of the body were to heal the same human limbs, and animal figurines were to heal and protect livestock (Ibid.). In Minoan shrines, bones of animals have also been found, of goats, sheep, pigs and even bulls (Ibid.). Possibly blood sacrifice was considered the most powerful (Ibid.). The power of priests and priestesses depended on their ability to win the favour of the gods, but the forces released beneath Thera’s surface could not be stopped any more (Ibid.). Consequently, confidence in the powers of priests weakened, which eventually led to the collapse of Minoan social and religious systems (Ibid.).
From the earthquake to Plinian eruption
From the structure of volcanic sediments in the initial phase of eruption, the island was covered with bright ash (Mitchell 2011). It was enough to poison the sources of drinking water (Ibid.). But it was not the worst awaiting the people living on Thera (Ibid.). What distinguished this eruption from all others experienced so far by the inhabitants of the island was the interaction of two types of magma that triggered a catastrophic chemical reaction (Ibid.). This reaction spewed about a hundred and fifty billion tons of magma onto the surface and made the eruption the greatest natural disaster of the ancient world (Ibid.). Columns of glowing gas of ash and stones flew at over nine kilometres up into the stratosphere, forming a cloud shaped like an atomic mushroom (Ibid.). Consequently, large clouds of rubble and dust rose into the sky after the explosion (Ibid.). Their force can be compared to the detonation of a nuclear bomb (Ibid.). The sound of explosion must have been heard even in Egypt, and clouds of smoke have been seen from Crete after a few minutes (Ibid.).
Thera’s eruption has been called the Plinian, which is the most devastating of all (Mitchell 2011). “Plinian eruptions or Vesuvian eruptions are […] marked by their similarity to the eruption of Mount Vesuvius in 79 AD, which destroyed the ancient Roman cities of Herculaneum and Pompeii. The eruption was described in a letter written by Pliny the Younger, after the death of his uncle Pliny the Elder” (“Plinian eruption” 2020). Hence its name. Such “eruptions are marked by columns of volcanic debris and hot gases ejected high into the stratosphere, the second layer of Earth’s atmosphere. The key characteristics are ejection of large amount of pumice and very powerful continuous gas-driven eruptions” (Ibid.)
During the first four hours of Thera’s eruption, the volcano ejected five billion tons of magma from the crater (Mitchell 2011). The day turned into night, because volcanic dust began to cover the entire island (Ibid.). The cooling magma began to fall as pumice (Ibid.). These were small stones filled with air bubbles but deadly in such large quantities (Ibid.). Prof. McCoy points out to the cliffs on Santorini, saying that at this stage of the eruption, the first layer was created (Lilley 2006). ‘[It] is that brown [one] at the bottom. [This] granular brown layer that’s pumice. Pumice is frothy rock. It represents magma frozen in place, a frozen explosion’, he says (Ibid.).
But it was ash, not pumice stone, that posed the greatest threat (Mitchell 2011). Volcanic ashes are different from ordinary ones, as they contain silicone (Ibid.). Drawn into wet human lungs, volcanic ash turns into liquid cement (Ibid.). Breathing then is difficult and finally impossible (Ibid.). Although archaeologists have not found any human remains in Akrotiri, it is still possible some residents of the town could have been stopped on the island, imprisoned by subsequent deadly effects of the eruption, either in their contemporary camps (Ibid.), or elsewhere on the island. Some scholars estimate that in Thera’s case, there were probably only few survivors who had escaped the island (Mitchell 2011).
Pyroclastic flows and torrential rains
The layer on top of the pumice from the cross-section of the cliffs proves the real power of this mighty eruption (Lilley 2006). This is the ash left by pyroclastic flows (Ibid.). ‘Pyroclastic flows [are made by] hot gas material that comes up and flows laterally across the landscape, sometimes at supersonic speeds’, says Prof. McCoy (Ibid.). These gases were forced out by massive explosions in the heart of the volcano, the caldera (Ibid.). But what caused these blasts? (Ibid.).
When the magma first erupted, it left behind a huge empty chamber (Lilley 2006). The surface above the chamber collapsed, creating a vast cavity (Ibid.). Then seawaters rushed into the expanding crater (Mitchell 2011; Lilley 2006). Upon contact with magma, the water turned into vapour, starting another wave of eruptions (Mitchell 2011). ‘Magma and water do not mix [but] create an explosion’, explains Prof. McCoy (Lilley 2006). ‘The entire Aegean Sea [was] pouring in this vent, mixing with new magma coming up and explosion was tremendous […] and from that [came] these pyroclastic flows’ (Ibid.).
The violent reaction of water with magma led to a phreatomagmatic eruptions (Mitchell 2011). It is estimated that the sound pressure level of this explosion reached three hundred decibels (Ibid.). It was enough to burst the tympanic membrane of everyone within sixteen kilometres (Ibid.). Moreover, the power of this eruption threw rocks from the inside of the crater, turning them into deadly rockets – lava bombs (Ibid.). Such burning lumps of stone could reach the size of a small truck and weigh up to eight tons (Ibid.). As the crater widened, the pressure was pushing the column upwards (Ibid.). The gases and rocks forming it began to fall in all directions (Ibid.). Pyroclastic flows reached the speed of two hundred and ninety kilometres per hour and a temperature of seven hundred degrees (Ibid.). Finally, the sizzling wave of rocks fell into the sea, and when it made the water surface boil, it began to move even faster on the layer of hot steam (Ibid.). After the final monstrous pyroclastic flow, ten metres deposit of ash and pumice were left, which have eventually formed the third layer that the best demonstrates the awesome forces of this eruption (Lilley 2006).
And on their top Santorini cliffs are built of the final, fourth layer (Lilley 2006). ‘It started to rain’, says Prof. McCoy (Ibid.). ‘Torrential rains came down and then all this loose ash and pumice on the surface started to move downslope. That’s what we call debris flows and then it was over’ (Ibid.).
What caused Thera eruption to be so far-reaching? (Masjum 2006). Thera sat on a string of volcanic islands straddling four plates (Ibid.). This convergence of plates creates the chain of volcanic islands and makes Thera eruption highly potent (Ibid.). Magma is formed when the African plate gets pushed beneath the Eurasian (Ibid.). The result is a gas rich and thick magma that erupts explosively (Ibid.). Prof. McCoy believes that the explosion was so loud that it could be heard throughout southern Europe, northern Africa and the Middle East (Ibid.).
More importantly, the blast has changed completely the shape of the land (Masjum 2006). Thousands years before the Minoan eruption, Santorini was believed to have joined as one island but after several eruptions the single island was blasted apart into smaller ones (Ibid.). At the time of the Minoans, the volcano was situated at the centre of these islands (Ibid.). When it erupted, it again changed the shape (Ibid.). When the centre of the volcano eventually collapsed, it formed a huge caldera (Ibid.). Today all that remains of the volcano is Nea Kameni, a tiny uninhabited island within the flooded Santorini caldera (Ibid.). With the birth of this new island the volcano is slowly rebuilding itself (Ibid.). Prof. McCoy claims that ‘over next twenty thousand years, this island is going to get larger and larger and then possibly it explodes again’ (Ibid.). ‘In the course of history of this volcano, an eruption repeats itself every twenty thousand years’, he explains (Ibid.).
Was the Thera eruption in the Bronze Age powerful enough to have destroyed the Minoans as well on Crete? (Lilley 2006).
Town under the ashes
Experts are only now learning the true scale of this disaster, which deadly impact stretched far beyond the island of Thera (Mitchel 2011). The volcano spewed out huge plumes of ash, carried by wind southwards (History Channel 1980s; Lilley 2006). It travelled from Thera to Crete in less than half an hour (Masjum 2006). When the dense clouds appeared, it must have seemed to the Minoans on Crete that nature had turned against them (Lilley 2006). ‘Imagine this ash coming over the island’, asks the professor of Greek archaeology, Jan Driesser (Ibid.). ‘It blackened the air [and] blue sky for several days’ (Ibid.).
In 1980s, Prof. McCoy and his colleagues found ash deposits on neighbouring islands and on the seabed near Crete (Lilley 2006). ‘We calculated the amount of the volume of this material, which is how we [figured] out how explosive [the] eruption had been’, says Prof. McCoy (Ibid.). Recent analysis of the seabed around the island has revealed that sediments from pyroclastic flow extend over thirty-two kilometres and are up to eighty meters deep (Mitchell 2011).
Excavations on the island itself, reveal that pyroclastic flow broke the upper fronts of the buildings on Thera (Mitchell 2011). Subsequently, the Minoan settlement was buried in a layer of volcanic ash and pumice stones more than forty meters deep (Jensen 2018).
With time, more evidence of Thera’s deadly deposits began to emerge not just from the Mediterranean but as far as the Black Sea (Lilley 2006). Volcanic ash must have plunged the region into darkness for weeks (Mitchell 2011). Computer modelling expert and volcano enthusiast, Dr Stuart Dunn, decided to plot the results by creating a database putting together all ash thicknesses with their locations (Lilley 2006). The location and thickness of these residues allowed to calculate how many millions of tons of material were blasted across the region (Ibid.). ‘We concluded that the eruption was very much larger than [it] was previously thought’, admits Prof. McCoy (Ibid.). ‘Now we’re up to ten times of the explosivity of Krakatau’, he concludes (Ibid.). After scientists, It was one of the most violent volcanic eruptions in human history, one hundred times the eruption of the volcano at St Helens and forty thousand times more powerful than the bomb dropped on Hiroshima (Mitchell 2011).
The clouds of ash caused the climate collapse over the whole region and subsequent lightning and hail storms (Masjum 2006; Wengler 2009). Temperature around the world lowered, inhibiting plant growth even in the British Isles (Mitchell 2011). Before collapsing into itself, the volcano expelled twenty billion cubic metres of molten lava and pumice has been found far inland of the Mediterranean region, where could have been carried by the waves of tsunami (Wengler 2009). Hundred and forty pumice stones from Thera’s eruption were found by Prof. Bietak in Avaris, in the Delta Nile (Ibid.). It is the same site, where the Egyptologist has found the Minoan fresco. Some number of pumice has been also found by archaeologists in Sinai (Ibid.).
Also this has prompted some scholars to suggest that the stories in the Bible may be linked to Thera eruption (Masjum 2006). In the Book of Exodus, signs of the ten Egyptian plagues include thunder and hail and total darkness, the phenomena that could have been volcanic in origin (Ibid.). And another plague mentioned in the Bible, namely the waters of the Nile turning into blood (Ibid.). Zeilinga de Boer explains that huge amounts of reddish dust, as upper layer in Santorini, and lot of dead material actually wiped out over the area of Egypt (Ibid.). He says that all this volcanic dust was in the atmosphere and was brought in the Nile by very heavy rains falling at a time and so the colour of the Nile could have changed from its natural into reddish tint (Ibid.). For the people of the entire Mediterranean observing such phenomena, the world must have descended into chaos (Ibid.).
Fire in the sky
Prof. McCoy assumes that in the morning, after the eruption, Minoans at Knossos and other towns along the northern coast, must have seen the clouds of smoke on the horizon (Masjum 2006). Although they must have already been frightened, they had no idea yet what was in store for them (Ibid.).
‘They saw black sky, lightnings, darkening clouds enveloping them and ash falling on the ground all around them. And constant earthquakes. For them the world looked like it was ending’, he says (Masjum 2006). ‘When something blew up, north of them, on the horizon, they must have known it was the island’, he speculates (Ibid.). ‘Maybe some [Cretans] had family or friends there. There was fire in the sky, […] ash falling out of the sky and even torrential rains coming along with the latter part of the eruption’ (Ibid.). Earthquakes from the eruption triggered further fires setting ablaze the Minoans temples, houses and other buildings (Ibid.). Climate change also badly influenced their agriculture (Ibid.). The effect on them must have been tremendous (Ibid.). Zeilinga de Boer adds that ‘the volcano brought a lot of pumice, the material that floats very easily and have covered apparently most of the eastern Mediterranean for years, making rowing or sailing impossible, so this commercial empire lost its major part of existence’ (Ibid.).
Until recently, many archaeologists believed that the ash from Thera suffocated the entire island but Dunn’s computer model shows that only the eastern part of Crete received a significant covering, whereas the western part of the island reminded virtually untouched (Lilley 2006). Prevailing winds blew most of the ash clouds away (Ibid.). If the ash did not cause the Minoans’ downfall, what then did? (Ibid.).
Catastrophe speeding up towards Crete
Today the serenity of Crete is a far cry from the fabled land of half-human monsters, bloody sacrifices or natural disasters (History Channel 1980s).
Much of what is encountered today seems barely to have changed in the course of its mysterious past (History Channel 1980s). Just in the ancient times, the forests were logged because the wood was needed for monumental architecture and ships (Ibid.). Sheep and goats graze here as they have for thousands of years (Ibid.). The work of farmers and shepherds give little hint that this island was once the center of a powerful commercial empire (Ibid.). After centuries of foreign occupations, residents here are more aware of their immediate past (Ibid.). The tale of the Minotaur has faded into a legend (Ibid.). Only at the beginning of the twentieth century, following the independence from the Ottoman Empire came archaeologists, such as Sir Arthur Evans, able to start digging into Crete’s great past (Ibid.).
The archaeologist, Dr Sandy McGillivray has been excavating the Minoan town of Palaikastro on eastern Crete (Lilley 2006). The extent of ruins found there suggests that this was the largest Minoan settlement after Knossos and home to around five hundred people, stretching from the mountainside to the seaside (Ibid.). Like in other Minoan settlements, paved roads with drains were laid on a grid pattern in its town plan (Ibid.). Palaikastro’s extensive workshops produced everything from basic foodstuffs to some of the finest art, yet discovered on Crete (Ibid.).
Today the small hill, the town stood on at the water’s edge is eroding into the sea (Lilley 2006). It reveals strange layers of chaotically mixed material of pottery, building material, stones, cattle bones and lumps of ash, reaching up to five metres above Minoan sea level (Ibid.). After Prof. Hendrik Bruins, a soil scientist who specializes in identifying and dating unusual layers, the deposit does not look like natural archaeological stratification or the result of an earthquake (Ibid.). To find out the origins of the strange deposits in Palaikastro, Prof. Bruins has conducted thorough laboratory studies (Ibid.). He was thrilled by the results (Ibid.). ‘We saw foraminifera in these deposits’, he says (Ibid.). Foraminifera are the shells of tiny organisms only found beneath the sea (Ibid.). Accordingly, it suggests that the deposit has been formed with the power of sea waves (Ibid.). Another marine creature within the soil sample is coralline algae from the seabed (Ibid.). ‘These come from below the sea level and in order to deposit them in that level, where we found them in a promontory, [they had] to be scooped up […] to [the] level, where the sea normally never comes’, explains Prof. Bruins (Ibid.). No storm would have lifted the algae from the seabed and left it stranded metres up on the island (Ibid.). Nevertheless, there is another powerful natural force that has the power to do that (Ibid.). These are tsunami waves (Ibid.). Are the Palaikastro beach deposits the terrifying footprint of a tsunami? (Ibid.).
Now it makes sense
Prof. Costas Synolakis, an expert on tsunami, has explored the excavated part of the Minoan town of Palaikastro, situated three hundred metres from the beach (Lilley 2006). He has found there further evidence that something extraordinary happened there in the far past (Ibid.).
The buildings of the town itself show unusual signs of damage (Lilley 2006). ‘We find some walls entirely missing’, says Dr Sandy McGillivray. Prof. Costas Synolakis claims that ‘this is what we [observe] in modern tsunamis. We call this the blow out. The sea comes in [and] blows out the walls. If the building is strong enough, the side walls […] will survive but the walls facing the ocean […] collapse’ (Ibid.). For Dr Sandy McGillivray ‘all of the sudden a lot of deposits [around Palaikastro] began making sense […] because [the town] had these buildings pulled away, [it] had the fronts of buildings missing. [it] had buildings raised right down the foundation level’ (Ibid.). What kind of wave was then powerful enough to cross three hundred metres of land before demolishing a town? (Ibid.).
The scientists also travelled further inland of Crete to find out how wide was the range of the waves terrible progress (Lilley 2006). Around one kilometre from the shore, and well above sea level, they have found deposits of seashell (Ibid.). Soil samples from excavation from ancient Palaikastro also contain the tale-tell microscopic signs of marine life, which is another evidence that the tsunami deluged the town (Ibid.).
When Thera erupted, it unleashed a powerful force into the sea (Masjum 2006). Scientists believe it caused giant waves of tsunamis (Ibid.). Hour after hour, pyroclastic flows on Thera were pushing volcanic debris into the sea, causing great tsunami waves that battered the Aegean coast (Masjum 2006; Mitchell 2011). ‘And then what happens is that the centre of the volcano […] has been blasted. it collapses to produce today’s caldera’, describes Prof. Floyd. ‘The land suddenly fell in, the ocean poured in and out producing constant tsunami’ (Masjum 2006). Inhabitants of nearby Crete could notice warning signs, but did not have enough time to react (Mitchell 2011). The first tsunami moving at the speed of three hundred and twenty kilometres per hour reached the coast of Crete within twenty minutes (Ibid.). At the time of contact with the land, the wave could have been up to twenty meters high (Ibid.).
Apparently, the tsunami generated by Thera eruption was powerful enough to ravage the entire civilization (Lilley 2006). On the north coast of Crete, fifty kilometres west along the coast from Palaikastro, Malia lies. Now it is known for ruins of a Minoan palace but once it was the third largest settlement on coastal Crete (Ibid.). Close by the ruins, the team of scientists has found the same layers of smashed pottery, building debris and crushed seashells that they have observed in Palaikastro (Ibid.). That is further evidence that a huge wave had struck the northern coast of Crete, dumping marine life onto the land (Ibid.). Next step was the study of the Minoan port of Amnissos (Ibid.). The site is located west of Malia and near the settlement of Knossos (Ibid.). Four thousand years ago, a villa nestled among olive groves on this idyllic coast (Ibid.). It was decorated with frescoes that celebrated the Minoan love of nature (Ibid.). But about the time of eruption of the volcano, the villa was destroyed and the frescoes torn from the walls (Ibid.). Pumice from Thera was once found in the ruins of this Minoan villa (Ibid.). Initially it was thought that the petrified volcanic froth may have been brought in there by a storm (Ibid.). However, the team has also found Thera pumice higher in the hills behind the villa, twenty metres above sea level, which may suggest it floated in on a massive tsunami (Ibid.).
Dr Sandy McGillivray says that he remembers from his childhood a big anthill at one end of the garden and as a child he used to go with a garden hose and wash ants off it (Lilley 2006). That memory keeps coming back to in his memory when he is thinking how the tsunami destroyed the Minoans on Crete (Ibid.). Tsunamis weeping people out to the sea must have been just like washing ants off the anthill. ‘It is a terrifying thing’, he admits (Ibid.). ‘Those ants never had a chance [to survive]’ (Ibid.). ‘Once the tsunami starts climbing up on dry land’, he continues (Ibid.). ‘It’s moving at [such] speed that nothing can stop it’ (Ibid.).
You wish you hadn’t found out …
Evidence gathered also demonstrates the range of destructive powers of the tsunami that would have struck on northern coasts of Crete (Lilley 2006).
As it can be concluded, when the caldera of Thera collapsed, it sent several walls of water into the Aegean Sea, like a pebble dropping into a pond (Lilley 2006). These waves cumulated around the islands and bounced off them (Ibid.). As a result, Crete was hit not by one but by several rebounding waves (Ibid.). The intervals between them were from around forty-five to thirty minutes (Ibid.). Recent studies have shown that more tsunamis ravaged cities on the northern coast of Crete for hours or even days after the eruption (Mitchell 2011). It is estimated that they killed from thirty to forty thousand people (Ibid.). After the first tsunami, there were surely Cretans who escaped but they came back to look for the injured and dead relatives and friends, smashed by the powerful wave (Lilley 2006). They did not realize that another wave was coming (Ibid.). Consequently, the survivors of the first wave may have become the victims of the second (Ibid.).
Dr McGillivray has been deeply moved by the obtained results. ‘You know, it’s like time looking for something and then when you find it, you wish you hadn’t because it becomes too real and, you know, you begin to feel the experience’, he admits (Lilley 2006). ‘This is life, this is people just being washed out to sea fast around […] There’s a whole instant that flashes through your head’ (Ibid.).
Mysterious legend that haunts to this day
The most massive volcanic eruption of the ancient world blew the island of Thera apart and buried for centuries all the evidence of the lives of people who had once called it home (Westbrook 1995). Yet memories have remained (Ibid.). Footprints in the dust have finally been discovered by archaeologists (Ibid.). There are, however, no written records left about the Thera’s eruption and subsequent tsunamis, no figures for the death and destruction it has caused (Lilley 2006). It is only known that the rich culture of the Minoans, one that awed and inspired the earliest civilizations of the Mediterranean, completely vanished at the end of the Bronze Age (History Channel 1980s). Was the powerful empire of the Minoans destroyed by natural forces or was there human intervention? (Ibid.).
On Thera, a massive eruption had buried Minoan streets and buildings beneath the flowing lava (History Channel 1980s). Meantime, clouds of ash engulfed the entire region (Ibid.). Crops were ruined and livestock suffocated (Ibid.). Consequently, all life on Santorini was destroyed (Ibid.). The utter destruction of the island and its people who settled there, must have left the powers of the region awestruck (Westbrook 1995). The palaeontologist, Charles Pellegrino, claims that the Egyptians must have known Thera (Ibid.). In the Bronze Age, it was surely known as a powerful colony of the Minoans (Ibid.). Egyptian ships would have travelled north to the very mountainous island for trading (Ibid.). After the volcano eruption, there was nothing but the silvers of broken rib-like land (Ibid.). Pellegrino thinks that to the ancient Egyptians finding the still smoking and blooming crater probably meant that the whole island and its inhabitants had simply sunk and disappeared (Ibid.). In centuries to come a great legend was heard of a Utopian island society that vanished in the sea “in a single day and night” (Ibid.).
Did the Egyptian priests mean Thera in their written story of the sunken island that they retold to Solon? According to some scholars, the history of the volcanic disaster on Thera may have been recorded by the ancient Egyptians and survived in repeatedly embellished stories (Mitchell 2011). In the fourth century BC., they may have inspired the Greek philosopher to write a morality play about the rise and fall of a great civilization, called Atlantis (Ibid.). For centuries, Plato’s words were considered a legend, until archaeologists discovered a lost world on Thera (Ibid.).
In one day and one night
The legend of Atlantis has teased human imagination ever since (Westbrook 1995). Some scholars definitely claims the story is a myth, others believe it is a true story and they either still keep looking for it or point to the small dot in the Aegean between Egypt, Greece and Asia, today just a rim of volcanic rock jutting out of the sea (Ibid.). Is Thera a legendary Atlantis? (Ibid.). Plato described the island of Atlantis as alternating rings of land and sea (Mitchell 2011). The port was full of ships and buyers from all over the world (Ibid.). Such great wealth had never been seen before (Ibid.). Bulls grazed at Poseidon’s temple, and ten princes hunted for them using wooden sticks and ropes (Ibid.). Then came powerful earthquakes and floods (Ibid.). In one day and one night, Atlantis was swallowed up by the sea and disappeared (Ibid.).
After some enthusiasts of the legend, like Pellegrino, there are some convincing clues and local finds that confirm that Plato’s Atlantis was in fact the island of Thera (History Channel 1980s; Mitchell 2011). “Like the Atlanteans, the Minoans were island-dwellers with shipyards, powerful fleets and a thriving maritime commerce. They had fine houses and superb artifacts, and were skilful builders and engineers – again like the Atlanteans. As in Atlantis, the bull, sacred to Poseidon the earth-shaker, was important in Minoan rituals (Harpur, Westwood 1997:21). Also Plato describes Atlantis as an island made of sea and land rings (Mitchell 2011). Thera’s reconstructions before the volcanic eruption show that the island could have fit this description (Ibid.). The unusual terrain was the effect of the most powerful geological forces on earth, always active beneath the island throughout its geological history (Ibid.). Nevertheless, there would have just been one concentric ring of land and two of water, building up the island, whereas Plato describes Atlantis as a fortified dwelling place with concentric rings, two of land and three of water (Harpur, Westwood 1997:18). Thera, as one of the Minoan colonies in the Mediterranean, was too small to be self-sufficient (Mitchell 2011), yet it was as wealthy and self-assured as much as the settlements of Minoans on Crete (Lilley 2006). Its geographical location made it an important trading point in the Mediterranean (Mitchell 2011). Its buyers acted as intermediaries by trading precious metals, oil, wine, ceramics and spices from Africa, Asia and Europe (Ibid.).
Also the bull, especially bull-leaping, is a recurring theme in Minoan art and there are many depictions of this powerful animal (Westbrook 1995). Such representations echo Plato’s description of Atlantis; there are described golden cups with scenes of bull ceremonies engraved on the sides, also analogous to Plato’s narrative (Ibid.). Such details as bulls being tied up by nooses and with rope furthermore match the author’s descriptions (Ibid.). Pellegrino also recounts the moment ‘early in [the twentieth] century, when the Minoan civilisation was being unearthed’ (Ibid.). ‘Some of the first archaeologists to arrive on the site, looking at the paintings of the bull ceremonies, and so on, said: ‘that’s Plato! That’s his Atlantis story!’, he claims (Ibid.). Plato also mentions that “first noble and innocent, the Atlanteans in time became power-hungry aggressors, seeking to subjugate neighbouring lands. Eventually, they were however, defeated by the Athenians, and then their island was destroyed by natural forces, earthquake and flood” (Harpur, Westwood 1997:18). As archaeological records suggest, the Greeks indeed invaded and conquered the Minoans in the second half of the fifteenth century BC. Moreover, like the wonderful civilization of Atlantis, Thera was destroyed by a terrible cataclysm during its greatest heyday and vanished (Westbrook 1995). “If Plato’s date for Atlantis, 9 000 years before Solon, were to lose a zero (a scribal error, perhaps, or storyteller’s exaggeration), [after some scholars], it would fit neatly into the timescale of Minoan culture” (Harpur, Westwood 1997:21).
Elephants on Thera?
“But problems remain, not least the fact that Plato explicitly states that Atlantis lay beyond the Pillars of Hercules, [on the Atlantic Ocean]” (Harpur, Westwood 1997:21). Although Thera’s explosion blew the island apart, it only precipitated the downfall of Minoan Crete, which eventually happened generations after the volcano eruption with the invasions of Mycenaeans from Greece (Ibid.:21). Correspondingly, the Minoans were not defeated by “the Athenians” before the natural disaster but long after it. There are also other differences between Plato’s story and archaeological facts about ancient Thera. Among animals living on Atlantis, there were elephants, which did not live on Thera, at least not in the Bronze Age (Ibid.:18). Thera was also too small to fit Plato’s description or to be divided into ten kingdoms between Poseidon’s descendants, like Atlantis actually was (Ibid.:18).
What is more, Crete and not Thera was the headquarters of the Minoan empire. And, unlike the legend of Atlantis says, Crete did not disappear in a single night (Westbrook 1995). It was only Thera that vanished (Ibid.). Plato does not either mention any volcano eruption on Atlantis but the fact the island was destroyed by earthquakes and floods (Masjum 2006). Moreover, although recurring representations of bull ceremonies are the traces left by the same civilization, the evidence is hardly found on Santorini (Westbrook 1995). Yet it is abundant on Crete (Ibid.). Or maybe was Thera (and the Minoans) just a legacy of the Atlanteans, and not Atlantis itself?
Fatal thread to Cretans
Prof. Walter Friedrich, a geologist, thinks that the volcano eruption was entirely fatal for Thera, but not for Crete (History Channel 1980s). For Cretans living on the northern coast of their island, the biggest thread came from the sea (Ibid.). Giant waves of tsunamis swept across the Aegean, destroying their glamorous architecture and powerful fleet (Ibid.). The tsunami was enough to bring a great civilization to its knees but there were survivors (Lilley 2006). Knossos, the Minoan capital was too far inland to be destroyed (Ibid.). According to archaeological evidence, the Minoans rebuilt their palaces, and although they never regained their full power and influence, they could still create exquisite works of art (Ibid.).
‘Did the volcanic eruption on Santorini directly destroy the Minoan culture’, asks Dr Don Evely, the archaeologist (Masjum 2006). ‘The answer is simply no. If, however, we ask a more subtle question: did it contribute to the decline? Did it undermine the Minoan power? The answer is almost certainly yes.’ (Ibid.). The devastating effects of Thera’s eruption on Crete are not limited to the number of dead and destroyed palaces (Mitchell 2011). Minoan society suffered a serious shock (Ibid.). Archaeological data testifies a deep social unrest; towns and temples were looted and set on fire (Ibid.). People were probably sacrificed (Ibid.).
Invaders from Greece
A final outburst of destruction overtook the Minoans in around 1450 BC (Lilley 2006). In western Crete, an excavation in the heart of the modern town of Chania has revealed evidence of arson, which proves strong fires once took place there (Ibid.). It is a pattern repeated also in other sites across the island (Ibid.). Was this a revolution within the Minoan society or is it the evidence of conquest by outsiders? (Ibid.). The archaeologist, Dr Maria Vlazaki, discovered a highly unusual cemetery in Chania (Ibid.). It dates from the same period as the widespread destruction in the Minoan world (Ibid.). ‘These are warrior graves’, she claims (Ibid.). ‘They are single burials, something that is in opposition with the traditional [Minoan grave. The buried were of the age] between twenty-four and thirty. They [were] tall, robust and they look [like] invaders’ (Ibid.). These invaders’ burials have been also found at Knossos and elsewhere on Crete so it suggests an invasion from the mainland of Greece (Ibid.). The invaders are believed to have slashed and burned their way across Crete, overwhelming the Minoans (Ibid.).
Dr McGillivray believes that the tsunamis and forthcoming social unrest may have actually helped the Mycenaeans to attack Crete (Lilley 2006). Coastal towns of the Minoans, like Malia, had no protective walls (Ibid.). Minoan defences rested instead on their control of the sea as the leading naval power in the ancient world (Ibid.). ‘The [islanders] were so confident in their navy that they were living in unprotected towns and cities all along the coastline’, he explains (Ibid.). All that naval force must have been, however, smashed and lost in the waves of tsunamis (Ibid.). Meantime, the fleet of Mycenae had grown in power (Ibid.). ‘[Their] traditional homeland is on the southern shores of the Gulf of Corinth’, says Dr McGillivray (Ibid.). The archaeologist thinks that the tsunami could not reach into there because of its geographical landscape and natural closure from the sea (Ibid.). ‘Mycenaean Greeks up there were probably the only people who had survived with a navy, possibly in the whole eastern Mediterranean’, he explains (Ibid.). Hence their upcoming powerful empire.
Did these invaders encounter a dark side of Minoan culture? (Lilley 2006). In Knossos, archaeologists have found grisly human remains (Ibid.). ‘One of the most telling and horrifying deposits from the post-Thera eruption period in Crete was a deposit recovered in the town of Knossos up along the Royal Road and that [were] these cannibalized youths’, says Dr McGillivray (Ibid.). ‘The analysis of these bones from this […] deposit strongly [suggests] that [the bones] have been hacked up in order to take the flesh off [and] eat [it]. This cannibalistic aspect of the Minoans is probably one of the things that was recalled when the Greeks first arrived in Crete’ (Ibid.). Was this an origin of the Minotaur myth? (Ibid.). Did the Greeks imagine that these unlucky victims had been led to the labyrinth to be sacrificed to the Minoan bull god? (Ibid.). Whatever is the truth of their myth’s origins, within a generation of their arrival, the Greeks had conquered Crete (Ibid.). The last embers of Minoan culture flickered out (Ibid.).
A major controversy
Dating the Thera’s eruption has become one of the major controversies in academic world.
“For more than two centuries archaeologists have refined the Bronze Age Mediterranean historical framework by observing the relative order of superimposed levels on a series of sites. Next, they established inter-site relationships based on common cultural characteristics – primarily in ceramics, art and architecture” (MacGillivray 2007:150). “Based on archaeological correlations between the Aegean, Egypt and the Levant, the eruption of Santorini was believed to have occurred around 1500 BC., after the beginning of the New Kingdom in Egypt, [that is to say in the sixteenth century BC.]” (Ehrlich, Regev, Boaretto 2018). “The traditional date around 1500 BC. was first proposed in the 1930s by Marinatos. It has […] been challenged by a controversial new date of around 1600 BC., dividing prehistorians into two camps and generating heated debate” (Castleden 1998-2001:191).
Turning for help to ancient Egyptians
In 1980s, two scientists first disputed the archaeological dating (History Channel 1980s). These were the German geologists, H. Pichler and W. L. Friedrich who radiocarbon-dated the charcoal found in the volcanic rocks (Ibid.). According to the results they obtained, the eruption of the volcano took place around 1650 BC. (Ibid.). It would mean that Thera’s explosion was over one hundred years earlier than it was primarily thought (History Channel 1980s; Wengler 2009). Accordingly, “the Minoans in [their] mature stages [would have been] contemporaries of the ‘Foreign Princes’ of Egypt’s Hyksos period, a century earlier than Hatshepsut’s reign in the historical chronology” (MacGillivray 2007:150).
In this case, some scholars turn for help to Egyptian texts, which “may give a clue to the absolute date [of Thera’s eruption” (MacGillivray 2007:159). And they find there interesting records, which may actually refer to the volcanic explosion and its devastating results. At the turning of the fifteenth century BC., “one of Hatshepsut’s best known dedications was the rock-cut temple to the lioness-goddess Pakhet, near Beni Hasan in Middle Egypt. […] Here, Hatshepsut carved a very revealing account of herself and her deeds in that region over the architrave” (Ibid.:159). Some scholars interpret the text “as Hatshepsut sending braziers to her subjects driven by raging storms and total darkness into the temples” (Ibid.:159). One of her deeds “was to care for refugees who swarmed into Middle Egypt from the Nile delta because of the incursion of the sea there” (Ibid.:160). There is also another text from much later Ptolemaic period (third or second centuries BC.), but referring to the events having happened during the Eighteenth Dynasty (Ibid.:160). Namely, the words of an Egyptian scribe recall biblical descriptions of darkness covering the earth (Ibid.:160). “[He writes:] ‘there was no exit from the palace by the space of nine days. Now these days were in violence and tempest: none, whether god or man, could see the face of his fellow’. This nine-day period reads suspiciously like an Egyptian multiple of three, which meant ‘a long time’, and so refers to a lengthy period of storms and darkness” (Ibid.:160).
Additionally, there is also a very interesting writing on the fragmented stele, ascribed by some scholars to Ahmose, the pharaoh and founder of the Eighteen Dynasty in the middle of the sixteenth century (Jacobovici, Cameron 2006). ‘It records some tremendous catastrophe that happened to Egypt’, says Prof. Donald Redford, the archaeologist (Ibid.). ‘We aren’t quite clear what it was but it involved rain and thunder and lightening, such a storm that rarely happens in northeastern Africa. I mean that’s a dry area’ (Ibid.). For this reasons, the stele has been known as the Tempest or Storm Stele (“Tempest Stele” (2020). Apart from ravaging storms, it also confirms that Egypt was enveloped in darkness and that statues of its gods were toppled to the ground, which may have happened due to a sequence of severe earthquakes (Jacobovici, Cameron 2006).
Such ancient records are usually pinpointed to the Eighteenth Dynasty, between the second part of the sixteenth and first part of the fifteenth century BC. But are these records dated correctly? If the stele had been really created by Ahmose and it talks about the Thera eruption, that would place it during the reign of the pharaoh, which is believed to have happened between 1550/49 and 1524 BC, or even twenty years earlier (MacGillivray 2007; “Ahmose I” 2020), which in turn, corresponds to the Late Minoan IA period (1600-1500 BC.). On the other side, Hatshepsut’s exact time of reigning is similarly unclear but usually estimated for the first half of the fifteenth century, sometimes between 1504-1483 or 1478-1458 BC. (MacGillivray 2007; “Hatshepsut” 2020), which mostly fell in the Late Minoan IB period (1500-1450 BC). If there are such discrepancies in dating the ruling of particular Egyptian kings, it is also highly probable some ancient texts are either wrongly ascribed (Ahmose’s stela refers just to a pharaoh, not Ahmose himself) or their date estimated incorrectly (Jacobovici, Cameron 2006).
Moving back to the seventeenth century BC., before Egypt’s consolidation by the Eighteenth Dynasty, it was the Egypt’s dark period (Wengler 2009). The kingdom of Egypt was split in two (Ibid.). The northern region (the Nile delta) was ruled by Hyksos, foreign invaders from Asia Minor (Ibid.). The time that followed brought economic decline and serious unrest (Ibid.) The rule of the Hyksos kings for long had reminded a trauma in the Egyptian minds (Ibid.). Did that period overlap with the volcano eruption on Thera?
Geologists make their way
For years now, doubts have been growing among scientists about the exact date of the eruption (Wengler 2009). On Santorini, colossal rocks were hurled through the air by the last great eruption of the Bronze Age (Ibid.).
Between these rocks, a geologist and student of Prof. Friedrich’s, Tom Pfeiffer, found in 2003 – as both geologists say – a critical evidence buried beneath the layers of lava (Wengler 2009; Volcano Discovery 2020). It was an olive branch of a tree smashed by Thera’s eruption (Wengler 2009). Around it, there were remains of olive leaves, twigs and olive stones, which signifies the tree was alive at the time of eruption (Ibid.). As it was an organic material, the remnants were carbon-dated (Ibid.). The moment, the olive branch died would mean the exact date of the volcanic eruption (Ibid.). Since the time of previous results, Prof. Friedrich obtained in 1980s, he has been convinced that the once accepted date of 1500 BC. for the eruption should be officially pushed back a hundred years (History Channel 1980s; Wengler 2009). He was sure that if the previous results had been confirmed by the results obtained by a recently found branch, the new timing would have been unchallengeable (Wengler 2009). Having conducted comparative tests, the geologists have received results confirming that the eruption took place in the seventeenth century BC. and not in the sixteenth century BC. or later (Ibid.). Accordingly, Santorini exploded somewhere between 1620 and 1600 BC (Ibid.). As Prof. Friedrich claims the confirmed date of the tree should have huge consequences for future research and for the understanding of ancient history in general (Ibid.).
Similar date has also been obtained by the soil specialist, Prof. Hendrik Bruins, who has studied Palaikastro’s deposits, which were accumulated by the tsunamis that had smashed the northern coast of Crete (Lilley 2006). He has radiocarbon-dated the cattle bone found on the beach in the deposit (Ibid.). According to the received results, the cattle bone comes from around 1600 BC. (Ibid.) For Prof. Bruins, who has been convinced that the Thera’s eruption took place around 1600 BC., it proves that the chaotic deposit is the result of the tsunami generated by the outbreak of the volcano (Ibid.). Thera’s eruption also produced “enormous volumes of ash and sulphuric acid aerosols which [usually] reduce atmospheric temperatures and may be detected in tree rings as years of slow growth” (Castleden 1998-2001:191). Forensic science and ancient records are also based on these dense clouds of ash across the Middle East and around the world (Westbrook 1995).
And they also pinpoint the years between 1628-1626 BC. to Thera’s eruption (Westbrook 1995). Although there is a difference of around thirty years between several independent studies, it is still the seventeenth century BC. they identify (Westbrook 1995; Castleden 1998-2001:191). Thera’s ash has also been found on the Nile, which is traced back to the same time period, like a fingerprint (Westbrook 1995). “An independent study of Irish bog oaks [has] revealed that 1628-1626 BC were very poor growth years. […] A search for acidity peaks in ice cores taken from the Greenland ice sheet failed to produce anything perceptible for 1500 BC., but revealed acidity peak for 1645 BC., which some eagerly identified as evidence of an early date for the Thera eruption” (Castleden 1998-2001:191).
Who is closer to the truth?
“In spite of the strenuous lobbying of a seventeenth-century BC. date, the evidence in its favour is inconclusive. To begin with, the eruptions are not the only cause of narrow tree rings: weather patterns vary for a great many reasons. […] From Thera itself comes a different kind of evidence. […] Some radiocarbon dates for the destruction level of Thera are too old for the […] eruption date. Charcoal from a Minoan hearth in the Athinios quarry in 1979 was dated to 1800 BC.; fava beans found in jug in Building 4 produced a date of 1700 BC. It has been claimed that [these] increasing numbers of radiocarbon dates favour the older date […] In fact, the average of over twenty radiocarbon dates from Akrotiri is 3200 BP, which rather calibrates to 1500 BC. (Castleden 1998-2001:191).
It is also worth to note that there can be some inaccuracies in standard carbon dating, leading to further mistakes in estimating an exact date for archaeological finds (Gorey 2018). “Research conducted by Cornell University [in 2018] could be about to throw the field of archaeology on its head with the claim that [due to] a number of inaccuracies in commonly accepted carbon dating standards, […] many of […] established historical timelines are thrown into question, potentially needing a re-write of the history books” (Ibid.).
In 2018, further attempts of dating have been conducted using tree rings.
According to University of Arizona-led research, “[new] analyses that [have used] tree rings could settle the long-standing debate about when the volcano Thera erupted by resolving discrepancies between archaeological and radiocarbon methods of dating the eruption, according to new research. […] ‘It’s about tying together a timeline of ancient Egypt, Greece, Turkey and the rest of the Mediterranean at this critical point in the ancient world – that’s what dating Thera can do’, said lead author Charlotte Pearson, an assistant professor of dendrochronology at the UA Laboratory of Tree-Ring Research. ‘What we can say now is that the radiocarbon evidence is compatible with the archaeological evidence for an eruption of Thera in the 16th century BC’, Pearson said” (Jensen 2018).
Is it a compromise?
The date of Thera volcanic eruption is regarded as crucial as it “has far reaching consequences in the archaeology of the Aegean, Egypt and the Levant, and the understanding of their interconnections” (Jensen 2018). This is why the fierce debate between the two camps, mainly between archaeologists and geologists has still been going on. Nevertheless, the UA Laboratory of Tree-Ring results have offered a provisional compromise.
“Archaeologists have estimated the eruption as occurring sometime between 1570 and 1500 BC by using human artifacts such as written records from Egypt and pottery retrieved from digs. Other researchers estimated the date of the eruption to about [1600-1650] BC. using measurements of radiocarbon, sometimes called carbon-14, from bits of trees, grains and legumes found just below the layer of volcanic ash. […] By using radiocarbon measurements from the annual rings of trees that lived at the time of the eruption, the UA-led team dates the eruption to someplace between 1600 and 1525” (Jensen 2018).
Although the results are more in favour of later dates for the eruption, as an estimated “time period overlaps with the 1570-1500 date range from the archaeological evidence” (Ibid.), the highest point of the same results points to the date of 1600 BC, also proposed by geologists.
If standard methods fail, scientists count on legends
With just few written records as their guide, scholars usually have no choice but to use legends as launching pads for their studies (Masjum 2006). ‘When volcanologists are trying to reconstruct an ancient eruption, [they] use everything [they] can, all the available data and certainly, there are a lot of collaboration between volcanologists, historians and archaeologists’, says Dr Rosaly Lopes Gaultier (Ibid.). ‘In Santorini, for example, it turned out to be a great collaboration because archaeologists can tell the things helping to date the eruption, while other scientists studying the volcano can tell more about the effects and sequence of events. So it ends up tying it all together. And you even look at legends and stories’ (Ibid.).
Today, the only things that have survived from the Minoan culture are the remains of their monumental architecture, being visited by flocks of tourists every summer (Masjum 2006). Yet for most the real story of the catastrophic disaster smashing the civilisation is too heavy for their relaxing vacation. Soon they abandon the ancient stones and go to sandy beaches. Yet, endowed with natural grandeur, the Aegean islands fire people imagination. In this idyllic landscape the atmosphere of the past is still very tangible. And it makes them unconsciously listen to its legends.
