 It is thought that Thucydides commented on the myth in his famous work on the Peloponnesian War because Sophocles' play confused the mythical Tereus with contemporary ruler Teres I of Thrace.The story of Philomela, Procne and Tereus is largely influenced by the lost tragedy "Tereus" of Sophocles.Scholar Jenny Marsh claims that Sophocles borrowed certain plot elements from Euripides drama "Medea"—notably a wife killing her child in an act of revenge against her husband—and incorporated them in his tragedy "Tereus".
