ALCMENE, in ancient Greek mythology, the daughter of Electryon, king of Mycenae, and wife of Amphitryon.
He fled with Alcmene, Electryon's daughter, to Thebes, where he was cleansed from the guilt of blood by Creon, his maternal uncle, king of Thebes.
Alcmene, who had been betrothed to Amphitryon by her father, refused to marry him until he had avenged the death of her brothers, all of whom except one had fallen in battle against the Taphians.
On his return to Thebes he married Alcmene, who gave birth to twin sons, Iphicles being the son of Amphitryon, Heracles of Zeus, who had visited her during Amphitryon's absence.
Amphitryon was the title of a lost tragedy of Sophocles; the episode of Zeus and Alcmene forms the subject of comedies by Plautus and Moliere.
In this character she pursues with vindictive hatred the heroines, such as Alcmene, Leto and Semele, who were beloved by Zeus.
