Domesticles was one of the Argonauts who sailed with Jason to bring the Golden Fleece to Argos. Ten years later, he was part of the second expedition of the Argo when Castor and the Blood-Eye Cult stole the Golden Fleece. He agreed to go on the second voyage only if Hercules would lead it as he didn't trust Jason who was in a depressed and alcoholic state. Domesticles was a master of the discus and worked well with Phoebe (HTLJ "Once a Hero").
