Sicyon was the son or grandson of Erechtheus. He married Zeuxippe, who bore him Chthonophyle - who in turn bore Polybus to Hermes. He is said to have given his name to the city of Sicyon on the Gulf of Corinth. If his name derives from sicyos, 'cucumber', then this may be either a 'fertility' name (even a phallic one) or else refer to some incident that has not come down to us.
