Phrynichus (/ˈfrɪnɪkəs/; Greek: Φρύνιχος), son of Polyphrasmon the Elder and pupil of Thespis, was one of the earliest of the Greek tragedians. Some of the ancients regarded him as the real founder of tragedy. Phrynichus is said to have died in Sicily. His son Polyphrasmon was also a playwright.
He gained his first victory in a drama contest in 511 BC. His famous play, the Capture of Miletus or the Sack of Miletus, was probably composed shortly after the conquest of that city by the Persians during the Ionian Revolt. Miletus was a colony of Athens and therefore traditionally held especially dear to the mother city. The audience was moved to tears by Phrynichus' tragedy, with the poet being fined "ὡς ὑπομνήσας οἰκεῖα κακά", "for reminding familiar misfortunes". As a result, the play was banned from being performed again. (Herodotus 6.21.10)
In 476 BC Phrynichus was successful with the Phoenissae, called after the Phoenician women who formed the chorus. This drama celebrated the defeat of Xerxes I at the Battle of Salamis four years earlier. provided the funds as choregos (producer), and one of the objectives of the play was to remind the Athenians of his great deeds. The Persians of Aeschylus (472 BC) was modeled after the Phoenissae.
