Krios Khrysomallos (greek, Κριος Χρυσομαλλος; latin, Crius Chrisomallus) was a fabulous, flying, golden-fleeced ram, sent by the cloud-nymphe Nephele to rescue her children Phrixos and Helle when they were about to be sacrificed to the gods. The ram carried Phrixos all the way to Kolkhis at the far end the Black Sea and then instructed the boy to sacrifice him to the gods and lay his fleece in the grove of Ares. Khrysomallos was afterwards placed amongst the stars as the constellation Aries.
