In ancient Greece, the symposium (Greek: συμπόσιον symposion or symposio, from συμπίνειν sympinein, "to drink together") was a part of a banquet that took place after the meal, when drinking for pleasure was accompanied by music, dancing, recitals, or conversation. Literary works that describe or take place at a symposium include two Socratic dialogues, Plato's Symposium and Xenophon's Symposium, as well as a number of Greek poems such as the elegies of Theognis of Megara. Symposia are depicted in Greek and Etruscan art that shows similar scenes.
In modern usage it has come to mean an academic conference or meeting such as a scientific conference. The equivalent of a Greek symposium in Roman society is the Latin convivium.
The Greek symposium was a key Hellenic social institution. It was a forum for men of respected families to debate, plot, boast, or simply to revel with others. They were frequently held to celebrate the introduction of young men into aristocratic society. Symposia were also held by aristocrats to celebrate other special occasions, such as victories in athletic and poetic contests. They were a source of pride for them.
Symposia were usually held in the andrōn (ἀνδρών), the men's quarters of the household. The participants, or "symposiasts", would recline on pillowed couches arrayed against the three walls of the room away from the door. Due to space limitations the couches would number between seven and nine, limiting the total number of participants to somewhere between fourteen and twenty seven (Oswyn Murray gives a figure of between seven and fifteen couches and reckons fourteen to thirty participants a "standard size for a drinking group"). If any young men took part they did not recline but sat up. However, in Macedonian symposia the focus was not only on drinking but hunting, and young men were allowed to recline only after they had killed their first wild boar.
