Overview
Amphitryon (; Ancient Greek: Ἀμφιτρύων, gen.: Ἀμφιτρύωνος; usually interpreted as "harassing either side", Latin: Amphitruo), in Greek mythology, was a son of Alcaeus, king of Tiryns in Argolis. His mother was named either Astydameia, the daughter of Pelops and Hippodamia, or Laonome, daughter of Guneus, or else Hipponome, daughter of Menoeceus. Amphitryon was the brother of Anaxo (wife of Electryon), and Perimede, wife of Licymnius. He was a husband of Alcmene, Electryon's daughter, and stepfather of the Greek hero Heracles.
Mythology
Born—according to tradition—in Tiryns,
in Argolis in the eastern part of the Peloponnese, Amphitryon became King of Troezen
and regent of Mycenae.
He was a friend of Panopeus.
Having accidentally killed his prospective father-in-law, Electryon, king of Mycenae, Amphitryon was driven out of Mycenae by Electryon's brother, Sthenelus. He fled with Alcmene to Thebes, where he was cleansed from the guilt of blood by Creon, king of Thebes.
Alcmene, who was pregnant and had been betrothed to Amphitryon by her father, refused to marry him until he had avenged the deaths of her brothers, all but one of whom had fallen in battle against the Taphians. (It was on his return from this expedition that Electryon had been killed.) Amphitryon accordingly took the field against the Taphians, accompanied by Creon, who had agreed to assist him on condition that he slew the Teumessian fox which had been sent by Dionysus to ravage the Theban countryside.
