Agathon
Agathon (; Greek: Ἀγάθων, gen.: Ἀγάθωνος; c. 448 – c. 400 BC) 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 lifelong companion 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 subjects. Agathon was also the first playwright to write choral parts which were apparently independent from the main plot of his plays.
