This list of mythical creatures that begin with this letter and I am constantly gathering information from each continent, and is continually being updated.
Chrysomallus (Greek mythology)
(Crius Chrysomallus) was a fabulous, flying, golden-fleeced ram. It was sent by the cloud-nymphe Nephele to rescue her children Phrixos (Phrixus) and Helle when they were about to be sacrificed to the gods. The ram carried Phrixos all the way to Kolkhis (Colchis) 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 and his shining fleece became the goal of the quest of Iason (Jason) and the Argonauts. Phrixus married a daughter of King Aeetes of Colchis and begot Argus and three other sons. The quest of Jason and the Argonauts was for this fleece. The legend of the Golden Fleece may have some basis in reality. Ancient Colchis is the modern Georgian region of Mingrelia.
