ALCMENE, the daughter of Electryon, king of Mycenae, was betrothed to her cousin Amphytrion; but, during his absence on a perilous undertaking, Zeus assumed his form, and obtained her affections. Heracles (whose
world-renowned exploits will be related among the legends) was the son of Alcmene and Zeus.

Alcmene and Hercules

At the time of his birth Alcmene was living at Thebes with her husband Amphitryon, and thus the infant Heracles was born in the palace of his stepfather.

Aware of the animosity with which Hera persecuted all those who rivalled her in the affections of Zeus, Alcmene, fearful lest this hatred should be visited on her innocent child, intrusted him, soon after his birth, to the care of a faithful servant, with instructions to expose him in a certain field, and there leave him, feeling assured that the divine offspring of Zeus would not long remain without the protection of the gods.

Soon after the child had been thus abandoned, Hera and Pallas-Athene happened to pass by the field, and were attracted by its cries. Athene pityingly took up the infant in her arms, and prevailed upon the queen of heaven to put it to her breast; but no sooner had she done so, than the child, causing her pain, she angrily threw him to the ground, and left the spot. Athene, moved with compassion, carried him to Alcmene, and entreated her kind offices on behalf of the poor little foundling. Alcmene at once recognized her child, and joyfully accepted the charge.
