When two twin brothers Castor and Pollux went off with Jason and the rest of the Argonauts, they sailed to Argo,a ship built by Argus. They sailed to Colchis(near the eastern border of the Black Sea) with fifty other men. After many adventures Jason (with help from Medea's) stole the fleece from the dragon and sailed home. Athene is said to have recognize this event by placing their ship (Argo Navis), in the sky as a giant constellation.
