Herakles (Ancient Greek: Ἡρακλῆς μαινόμενος, Hēraklēs Mainomenos, also known as Hercules Furens) is an Athenian tragedy by Euripides that was first performed c. 416 BC. While Herakles is in the underworld obtaining Cerberus for one of his labours, his father Amphitryon, wife Megara, and children are sentenced to death in Thebes by Lycus. Herakles arrives in time to save them, though the goddesses Iris and Madness (personified) cause him to kill his wife and children in a frenzy. It is the second of two surviving tragedies by Euripides where the family of Herakles are suppliants (the first being Herakles' Children). It was first performed at the City Dionysia festival.
