Agathon (; ; ) was an Athenian tragic poet whose works have been lost. He is best known for his appearance in Plato's Symposium, which describes the banquet given to celebrate his obtaining a prize for his first tragedy at the Lenaia in 416. He is also a prominent character in Aristophanes' comedy the Thesmophoriazusae. Life and career Agathon was the son of Tisamenus, and the lover of Pausanias, with whom he appears in both the Symposium and Plato's Protagoras. Together with Pausanias, he later moved to the court of Archelaus, king of Macedon, who was recruiting playwrights; it is here that he probably died around 401 BC. Agathon introduced certain innovations into the Greek theater: Aristotle tells us in the Poetics (1456a) that the characters and plot of his Anthos were original and not, following Athenian dramatic orthodoxy, borrowed from mythological or historical subjects. Agathon was also the first playwright to write choral parts which were apparently independent from the main plot of his plays. Agathon is portrayed by Plato as a handsome young man, well dressed, of polished manners, courted by the fashion, wealth and wisdom of Athens, and dispensing hospitality with ease and refinement. The epideictic speech in praise of love which Agathon recites in the Symposium is full of beautiful but artificial rhetorical expressions, and has led some scholars to believe he may have been a student of Gorgias. In the Symposium, Agathon is presented as the friend of the comic poet Aristophanes, but this alleged friendship did not prevent Aristophanes from harshly criticizing Agathon in at least two of his comic plays: the Thesmophoriazousae and the (now lost) Gerytades. In the later play Frogs, Aristophanes softens his criticisms, but even so it may be only for the sake of punning on Agathon's name (ἁγαθός "good") that he makes Dionysus call him a "good poet". Agathon was also a friend of Euripides, another recruit to the court of Archelaus of Macedon. Physical appearance Agathon's extraordinary physical beauty is brought up repeatedly in the sources; the historian W. Rhys Roberts observes that "ὁ καλός Ἀγάθων (ho kalos Agathon) has become almost a stereotyped phrase." The most detailed surviving description of Agathon is in the Thesmophoriazousae, in which Agathon appears as a pale, clean-shaven young man dressed in women's clothes. Scholars are unsure how much of Aristophanes' portrayal is fact and how much mere comic invention. After a
