Syssitia

The syssitia (in Classical Greek τὰ συσσίτια / ta syssítia) was, in Ancient Greece, a common meal for men and youths in social or religious groups, especially in Crete and Sparta, though also in Megara in the time of Theognis (6th century BC) and Corinth in the time of Periander (7th century BC).

The banquets spoken of by Homer relate to this tradition. Some reference to similar meals can be found in Carthage and according to Aristotle (Politics VII. 9), it prevailed still earlier amongst the Oenotrians of Southern Italy.

The origin of the syssitia is unknown; while Lycurgus certainly made use of the practice in Sparta, we do not know whether he introduced the practice or developed an existing one.
