The evidence of the Marmor Parium confirms that Sophokles ‘died under Kallias’, who was archon from the summer of 406 to the summer of 405. The Frogs was produced during the archonship of the same Kallias, at the Lenaia: that is, in January/February 405. The Frogs refers to the dead poet in the prologue, in the second prologue, and in the exodos (76–82, 786–94, 1515–19): in the prologue and in the exodos Sophokles is mentioned in connexion with the return of Dionysos from Hades with a good tragic poet (cf. 71–85 and 1414–1533), and in the second prologue in connexion with the contest between Aeschylus and Euripides for the tragic throne in Hades (cf. 757–1410).
