the end of his life; and that he refuted their charge in court by reading from his new Oedipus at Colonus. One of his sons, Iophon, and a grandson, called Sophocles, also became playwrights. Homosexuality An ancient source, Athenaeus’s work Sophists at Dinner, contains references to Sophocles' sexuality. In that work, a character named Myrtilus claims that Sophocles "was partial to boys, in the same way that Euripides was partial to women" ("φιλομεῖραξ δὲ ἦν ὁ Σοφοκλῆς, ὡς Εὐριπίδης φιλογύνης"), and relates an anecdote, attributed to Ion of Chios, of Sophocles flirting with a serving-boy at a symposium: He also says that Hieronymus of Rhodes, in his Historical Notes, claims that Sophocles once led a boy outside the city walls for sex; and that the boy snatched Sophocles' cloak (χλανίς, khlanis), leaving his own child-sized robe ("παιδικὸν ἱμάτιον") for Sophocles. Moreover, when Euripides heard about this (it was much discussed), he mocked the disdainful treatment, saying that he had himself had sex with the boy, "but had not given him anything more than his usual fee" ("ἀλλὰ μηδὲν προσθεῖναι"), or, "but that nothing had been taken off" ("ἀλλὰ μηδὲν προεθῆναι"). In response, Sophocles composed this elegy: Works and legacy Sophocles is known for innovations in dramatic structure; deeper development of characters than earlier playwrights; and, if it was not Aeschylus, the addition of a third actor, which further reduced the role of the chorus, and increased opportunities for development and conflict. Aeschylus, who dominated Athenian playwriting during Sophocles' early career, adopted the third actor into his own work. Besides the third actor, Aristotle credits Sophocles with the introduction of skenographia, or scenery-painting; but this too is attributed elsewhere to someone else (by Vitruvius, to Agatharchus of Samos). After Aeschylus died, in 456 BC, Sophocles became the pre-eminent playwright in Athens, winning competitions at eighteen Dionysia, and six Lenaia festivals. His reputation was such that foreign rulers invited him to attend their courts; but, unlike Aeschylus, who died in Sicily, or Euripides, who spent time in Macedon, Sophocles never accepted any of these invitations. Aristotle, in his Poetics (c. 335 BC), used Sophocles' Oedipus Rex as an example of the highest achievement in tragedy. Only two of the seven surviving plays can be dated securely: Philoctetes to 409 BC, and Oedipus at Colonus to 401 BC (staged after his death, by his grandson). Of the others, Electra shows stylistic similarities to
