1. A son of Melaneus and Stratonice was king of Oechalia, probably the Thessalian town of this name. He was a skilful archer and married to Antioche, by whom he became the father of lole, Iphitus, Molion or Deion, Clytius, and Toxeus.
He was proud of his skill in using the bow, and is even said to have instructed Heracles in his art. He offered his daughter Iole as prize to him who should conquer him and his sons in shooting with the bow. Heracles won the prize, but Eurytus and his sons, with the exception of Iphitus, refused to give up Iole, because they feared lest he should kill the children he might have by her.
Heracles accordingly marched against Oechalia with an army: he took the place and killed Eurytus and his sons.
According to a tradition in Athenaeus he put them to death because they had demanded a tribute from the Euboeans.
The remains of the body of Eurytus were believed to be preserved in the Carnasian grove and in the Messenian Oechalia sacrifices were offered to him every year.
3. A son of Hermes and Antianeira, and brother of Echion, was one of the Argonauts.
He is sometimes also called Erytus.
