The Megalithic Structure of Trilithon in the Worldwide Architecture

The definition of trilithon or trilith is derived from the Greek words, which stand for “‘having three stones’ (τρι-/tri- ‘three’ + λίθος/lithos ‘stone’)” (“Trilithon” 2021). The word trilithon was primarily applied by an English antiquarian, physician and Anglican clergyman, William Stukeley (1687-1765), who had “a significant influence on the later development of archaeology. [He] pioneered the scholarly investigation of the prehistoric monuments of Stonehenge and Avebury in Wiltshire [and] published over twenty books on archaeology and other subjects during his lifetime” (“William Stukeley” 2021).

Precisely, trilithon is a megalithic structure consisting of three boulders: two vertical and the third arranged horizontally. In such constructions, the two large vertical stones, called posts, constitute the only support for the third stone, which is set horizontally across the top, referred to as a lintel.

The definition of trilithon “is commonly used in the context of megalithic monuments”. Trilithons were built in the Neolithic and Bronze Age, possibly as religious objects or astronomical observatories. “The most famous trilithons are those of Stonehenge in England, those found in the Megalithic temples of Malta […] and the Osireion in Egypt. […] The term also describes the groups of three stones in the Hunebed tombs of the Netherlands and the three massive stones forming part of the wall of the [so-called] Roman Temple of Jupiter at Baalbek, Lebanon. Far from Europe and the Middle East, another famous trilithon is the Haʻamonga ʻa Maui in Tonga, Polynesia” (“Trilithon” 2021).

Tablinum – Main Living Room in a Former Italian House

From the late Latin tab(u)linum – a kind of gallery, terrace in the Roman house.

“[Tablinum] was a room, generally situated on one side of the atrium and opposite to the entrance; it opened in the rear onto the peristyle, with either a large window or only an anteroom or curtain” (“Tablinum” 2021). In the later Roman house, the tablinum was situated between an atrium with which it was connected, and the hortus (garden). Initially, it housed a marriage bedroom, then “the main office and reception room for the house master. [As such, tablinum] was the office in a Roman house, the father’s centre for business” (Ibid.) Over time, it was transformed into a reception room, “where [a master] would receive his clients. [At that time, its] walls were richly decorated with fresco pictures, and busts of the family were arranged on pedestals on the two sides of the room” (Ibid.).
