In Ancient Greece, the symposium (Greek: συμπόσιον, sympósion or symposio, from συμπίνειν, sympínein, "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.
A symposium would be overseen by a "symposiarch" (Greek: συμπόσιάρχης : symposiárchēs) who would decide how strong the wine for the evening would be, depending on whether serious discussions or sensual indulgence were in the offing. The Greeks and Romans customarily served their wine mixed with water, as the drinking of pure wine was considered a habit of uncivilized peoples. However, there were major differences between the Roman and Greek symposia. A Roman symposium (convivium) served wine before, with and after food, and women were allowed to join. In a Greek symposium, wine was only drunk after dinner, and women were not allowed to attend.
The wine was drawn from a krater, a large jar designed to be carried by two men, and served from pitchers (oenochoe). Determined by the Master of Ceremonies, the wine was diluted to a specific strength and was then mixed. Slave boys would manage the krater, and transfer the wine into pitchers. They then attended to each man in the symposium with the pitchers and filled their cups with wine. Certain formalities were observed, most important among which were libations, the pouring of a small amount of wine in honour of various deities or the mourned dead. In a fragment from his c. 375 BC play Semele or Dionysus, Eubulus has the god of wine Dionysos describe proper and improper drinking:
For sensible men I prepare only three kraters: one for health (which they drink first), the second for love and pleasure, and the third for sleep. After the third one is drained, wise men go home. The fourth krater is not mine any more – it belongs to bad behaviour; the fifth is for shouting; the sixth is for rudeness and insults; the seventh is for fights; the eighth is for breaking the furniture; the ninth is for depression; the tenth is for madness and unconsciousness.
In keeping with the Greek virtue of moderation, the symposiarch should have prevented festivities from getting out of hand, but Greek literature and art often indicate that the third-krater limit was not observed.
Symposiums are often featured on Attic pottery and Richard Neer has argued that the chief function of Attic pottery was for use in the symposium. An amphora was used as a jug to hold the wine and usually one single cup was passed amongst the men. Cups used at symposiums were not as nearly intricate as amphoras. Pottery used at symposiums often featured painted scenes of the god Dionysus, satyrs, and other mythical scenes related to drinking and celebration.
Poetry and music were central to the pleasures of the symposium. Although free women of status did not attend symposia, high-class female prostitutes (hetairai) and entertainers were hired to perform, consort, and converse with the guests. Among the instruments women might play was the aulos, a Greek woodwind instrument sometimes compared to an oboe. When string instruments were played, the barbiton was the traditional instrument. Slaves and boys also provided service and entertainment.
The guests also participated actively in competitive entertainments. A game sometimes played at symposia was kottabos, in which players swirled the dregs of their wine in a kylix, a platter-like stemmed drinking vessel, and flung them at a target. Another feature of the symposia were skolia, drinking songs of a patriotic or bawdy nature, performed competitively with one symposiast reciting the first part of a song and another expected to improvise the end of it. Symposiasts might also compete in rhetorical contests, for which reason the word "symposium" has come to refer in English to any event where multiple speeches are made.
Etruscan art shows scenes of banqueting that recall aspects of the Greek symposia; however, one major difference is that women of status participated more fully in this as in other realms of Etruscan society. Women were allowed to drink wine and recline with men at feasts. Some Etruscan women were even considered "expert drinkers". Additionally, Etruscan women were often buried with drinking and feasting paraphernalia, suggesting that they partook in these activities. The most apparent distinctions between Greek and Etruscan drinking parties appear in Etruscan art. Etruscan paintings show men and women drinking wine together and reclining on the same cushions. The Sarcophagus of the Spouses, found in the Etruscan region dating to 520–530 BC, depicts a man and women lounging together in the context of a banquet, which is a stark contrast with gendered Greek drinking parties.
As with many other Greek customs, the aesthetic framework of the symposium was adopted by the Romans under the name of comissatio. These revels also involved the drinking of assigned quantities of wine, and the oversight of a master of the ceremonies appointed for the occasion from among the guests. Another Roman version of the symposium was the convivium. Women's roles differed in Roman symposia as well. Roman women were legally prohibited from drinking wine as a matter of public morality. Men were expected to control their own wine consumption, but women were not given this authority.
