Brother of Nycteus in Greek mythology, Lycus was brother-in-law to Antiope whom Zeus impregnated. She fled in shame to King Epopeus of Sicyon and abandoned her children, Amphion and Zethus. They were exposed on Mount Cithaeron, but were found and brought up by a shepherd. Nycteus, unable to retrieve his wife, sent his brother Lycus to take her. He did so and gave her as a slave to his own wife, Dirce.
One of the four sons of Pandion. Upon the death of Pandion, Lycus and his brothers (Aegeas, Nisos, and Pallas) took control of Athens from Metion, who had seized the throne from Pandion. They divided the government in four but Aegeas became king. He became the ancestor of the Lycians of Asia Minor.
