Pan

Pan, in Greek mythology, was the god of the country, and in later times of all nature, and his parentage was ascribed to Hermes, Zeus, or Apollo, and Callisto or (Enoc. He was represented as possessing the lower limbs of a goat, horns on his bead, and half-human features. His voice inspired terror; hence the derivative "panic." Arcadia was the chief seat of his worship, and there he was supposed to wander on the mountains in the company of the nymphs and satyrs, playing on the pipes and dancing. Prophetic powers were attributed to him, and he promoted the fecundity of the flocks and herds.
