Lycus of Libya

Lycus or Lykos (Λύκος), in Greek mythology, was a king of Libya and son of the god Ares and the father of Callirhoê.

Mythology
Lycus had the custom of sacrificing strangers to his father. After the sack of Troy, Diomedes was cast up on the Libyan coast and when he was being sacrificed, the king's daughter Callirhoê fell in love with the hero and betrayed her father. She loosened Diomedes from his bonds and rescued him eventually, but committed suicide upon his departure.
