Greek: ostraca (plural) – oyster shells, ostracon (singular).
Ostracon is usually understood as a potsherd (“a piece of pottery, usually broken off from a vase or other earthenware vessel” (“Ostracon” 2021) or a flat stone piece (normally a flake of limestone), which was mainly used by artists from ancient Egypt and Greece for their freehand sketches and written notes.
“Generally discarded material, ostraca were cheap, readily available and therefore frequently used for writings of an ephemeral nature such as messages, prescriptions, receipts, students’ exercises and notes” (“Ostracon” 2021). Very exceptional are “the so-called figural ostracons [featuring] drawings, often sketches by artists or architects. The artists sketched their ideas on them with great freedom, avoiding the limitations of official art, thanks to which their sketches were more spontaneous, not devoid of the sense of accurate observation and a clear satirical message. One of the most beautiful and known examples of an ostracon paintings is a representation of an Egyptian dancer performing a somersault (Deir el-Medina, the New Kingdom, between sixteenth and the eleventh centuries BC.; see: Egyptian Dancer from Turin and Her Acrobatic Somersault).

Either a satire on upper-class life, or perhaps a scene from a fable. New Kingdom, either nineteenth or twentieth dynasties, circa 1295-1070 BC., from Thebes. Photo by Keith Schengili-Roberts (2007).
