Alectryon
Alectryon (rooster, cock) In Greek mythology, a youth who was to watch for the approach of the sun when Ares was making love to Aphrodite so that they would not be discovered by her husband, Hephaestus.
Alectryon fell asleep, and the two lovers were discovered. In anger Ares turned Alectryon into a cock, which still heralds the dawn.
