[Persian] The Iranian primeval king who rules a realm where justice, order and abundance prevail. His name means "twin" and his wife and twin sister is Yimak. As king Yam he fulfils three social functions: he is pious as a priest, strong as a warrior, and rich as a large landowner. He was the favorite of the gods, but he fell from grace when he became disdain and mendacious, and he lost his immortality.
