Sophocles, son of Sophilus, from the deme of Colonus, an Athenian tragic poet, born in the 73rd Olympiad (488/5 BCE), so that he was 17 years older than Socrates. He was the first to use three actors and the so-called tritagonist, and he was the first to introduce a chorus of fifteen young men, there having previously been twelve chorus members. He was called ‘the bee’ on account of his sweetness. He himself started the custom of pitting one drama against another, rather than competing by general levy, as it were. He wrote an elegy and paeans and a prose tract on the chorus, in which he takes issue with Thespis and Choirilus. He had the following children: Iophon, Leosthenes, Ariston, Stephanus, Menecleides. He died after Euripides, aged ninety. He produced one hundred and twenty three dramas; as some say, many more. He won twenty four victories.
