Amphitryon

Amphitryon was a human husband of Alcmene and step-faher of Heracles. He had a son named Iphicles and accepted Heracles as his own son. He was the son of Alcaeus and Astydamia, therefore being a paternal grandson of Perseus and a maternal grandson of Pelops. His two uncles were kings of Argos.

Mythology
Amphitryon was a Theban general, who was originally from Tiryns in the eastern part of the Peloponnese. He was friends with Panopeus.

Having accidentally killed his father-in-law Electryon, king of Mycenae, Amphitryon was driven out by Electryon's brother, Sthenelus. He fled with Alkmene, Electryon's daughter, to Thebes, where he was cleansed from the guilt of blood by Creon, king of Thebes.

Alkmene, who was pregnant and had been betrothed to Amphitryon by her father, refused to marry him until he had avenged the death 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 country.

The Taphians, however, remained invincible until Comaetho, the king's daughter, out of love for Amphitryon cut off her father's golden hair, the possession of which rendered him immortal. Having defeated the enemy, Amphitryon put Comaetho to death and handed over the kingdom of the Taphians to Cephalus. On his return to Thebes, he married Alkmene, who gave birth to twin sons, Iphicles and Heracles. Only the former was the son of Amphitryon because Heracles was the son of Zeus, who had visited Alcmene during Amphitryon's absence. He and Alkmene also had a daughter named Laonome.

He fell in battle against the Minyans, against whom he had undertaken an expedition, accompanied by the youthful Heracles, to deliver Thebes from a disgraceful tribute.
