Corax (mythology)
In Greek mythology, Corax (Ancient Greek: Κόραξ Korax or Κόρακος means 'raven') or Corex was the 16th king of Sicyon who reigned for 30 years. Family 
Corax was the elder son and heir of King Coronus, descendant of the city's founder Aegialeus. He was brother of Lamedon. Mythology 
In some versions of the myth, Corax received the throne from his predecessor Echyreus, in whose reign Danaus became the king of Argos. After Corax died childless, Lamedon was his rightful successor, but Lamedon was usurped by Epopeus who came from Thessaly and seized the kingdom from him. In the latter's reign, the conflict between Sicyon and Thebes ensued. Notes
