EUPOLIS (c. 1 B.c.) , Athenian poet of the Old Com edy, flourished in the time of the Peloponnesian War. He is said to have been drowned by Alcibiades, whom he had attacked in one of his plays, but it is more likely that he died fighting for his country. He is ranked by Horace (Sat.i.4,I) along with Cratinus and Aris tophanes, as the greatest writer of his school. He was reputed to equal Aristophanes in the elegance of his style and Cratinus in his command of satire. Although he was at first on good terms with Aristophanes, their relations later became strained, and they accused each other of plagiarism. Of the 17 plays attributed to Eupolis, with which he won the first prize seven times, only frag ments remain. Of these the best known were : the Kolakes, di rected against the spendthrift Callias (q.v.) ; Marikas, an attack on Hyperbolus, the demagogue; the Baptai, against Alcibiades and his clubs. The Demoi and Poleis were political, dealing with the desperate condition of the state and with the allied (or tributary) cities.
