In Greek mythology, the Golden Fleece (Χρυσόμαλλον δέρας, Chrysómallon déras, literally, Golden-haired pelt) is the fleece of the golden-woolled, winged ram, Chrysomallos, that rescued Phrixus and brought him to Colchis, where Phrixus then sacrificed it to Zeus. Phrixus gave the fleece to King Aeëtes who kept it in a sacred grove, whence Jason and the Argonauts stole it with the help of Medea, Aeëtes' daughter. The fleece is a symbol of authority and kingship.
In the historical account, the hero Jason and his crew of Argonauts set out on a quest for the fleece by order of King Pelias in order to place Jason rightfully on the throne of Iolcus in Thessaly. Through the help of Medea, they acquire the Golden Fleece. The story is of great antiquity and was current in the time of Homer (eighth century BC). It survives in various forms, among which the details vary.
Nowadays, the heraldic variations of the Golden Fleece are featured frequently in Georgia, especially for Coats of Arms and Flags associated with Western Georgian (Historical Colchis) municipalities and cities, including the Coats of Arms of City of Kutaisi, the ancient capital city of Colchis.
Athamas the founder of Thessaly, but also king of the city of Orchomenus in Boeotia (a region of southeastern Greece), took the goddess Nephele as his first wife. They had two children, the boy Phrixus (whose name means "curly," as in the texture of the ram's fleece) and the girl Helle. Later Athamas became enamored of and married Ino, the daughter of Cadmus. When Nephele left in anger, drought came upon the land.
Ino was jealous of her stepchildren and plotted their deaths; in some versions, she persuaded Athamas that sacrificing Phrixus was the only way to end the drought. Nephele, or her spirit, appeared to the children with a winged ram whose fleece was of gold. The ram had been sired by Poseidon in his primitive ram-form upon Theophane, a nymph and the granddaughter of Helios, the sun-god. According to Hyginus, Poseidon carried Theophane to an island where he made her into a ewe so that he could have his way with her among the flocks.
