Alectryon (mythology)

Two roosters on an ancient Greek black-figure vase from Villa Giulia.

Alectryon (from Ancient Greek: ἀλεκτρυών, Alektruṓn pronounced [alektryɔ̌ːn], literally meaning "rooster") in Greek mythology, was a young soldier who was assigned by Ares, the god of war, to guard the outside of his bedroom door while the god took part in a love affair with the love goddess Aphrodite. Alectryon however failed at his job when he fell asleep, allowing Helios, the god of the Sun, to see the two lovers and alert Hephaestus, the husband of Aphrodite, who then caught the two lovers in the act. Enraged with Alectryon's incompetence, Ares changed him into a rooster in anger. In his effort to reconcile, Alectryon never skipped on alarming people of Helios's arrival thereafter.

The story is an aetiological myth that attempts to explain both the origin of the roosters and the reason why they crow each morning at dawn, warning of the Sun approaching. The myth is not mentioned by Homer, who first related the story of Ares and Aphrodite's infidelity in his Odyssey, but rather it was interpolated later by various authors.
