A dragon or serpent that terrorized the island of Salamis. There are two versions about how it was defeated. According to Apollodorus,1 the hero Cychreus killed the monster, after which he became the king of the island. Strabo2 however, states that — according to Hesiod — the serpent was reared by Cychreus from which it took its name. It was driven out by Eurolochus and welcomed to Eleusis by Demeter and made her attendant.
