Kottabos (Ancient Greek: κότταβος) was a game of skill played at Ancient Greek and Etruscan symposia (drinking parties), especially in the 6th and 5th centuries BC. It involved flinging wine-lees (sediment) at a target in the middle of the room. The winner would receive a prize (κοττάβιον or "kottabion"), comprising cakes, sweetmeats, or kisses.
Ancient writers, including Dionysius Chalcus, Alcaeus, Anacreon, Pindar, Bacchylides, Aeschylus, Sophocles, Euripides, Aristophanes, and Antiphanes, make frequent and familiar allusion to the practice; and it is depicted on contemporaneous red-figure vases. References to the practice by the writers of the Roman and Alexandrian periods show that the fashion had died out. In Latin literature, it is almost entirely unknown.
