Although Sophocles won second prize with the group of plays that included Oedipus Rex, its date of production is uncertain. The prominence of the Theban plague at the play's opening suggests to many scholars a reference to the plague that devastated Athens in 430 BC, and hence a production date shortly thereafter.

Cartwright, Mark. "Greek Religion". World History Encyclopedia. Retrieved 17 January 2017. "... These traditions were first recounted only orally as there was no sacred text in Greek religion and later, attempts were made to put in writing this oral tradition, notably by Hesiod in his Theogony and more indirectly in the works of Homer.
