In Roman mythology, fauns are place-spirits of untamed woodland. Romans connected their fauns with Greek satyrs, wild and orgiastic drunken followers of Bacchus. However, fauns and satyrs were originally quite different creatures. Both have horns and both resemble goats below the waist, humans above; but originally fauns had goat-like hooves, satyrs human feet. The Romans also had a god named Faunus and goddess Fauna, who, like the fauns, were goat-people.
Pan in Greek religion and mythology, is the companion of the nymphs, god of shepherds and flocks, of mountain wilds, hunting and rustic music. Two other Pans were Argeus and Nomios. Like Pan, both were the sons of Hermes, Argeus' mother being the nymph Sose, a prophetess: he inherited his mother's gift of prophecy, and was also a skilled hunter. Nomios' mother was Penelope (not the same as the wife of Odysseus). He was an excellent shepherd, seducer of nymphs, and musician upon the shepherd's pipes. Most of the mythological stories about Pan are actually about Nomios, not the god Pan. Although, Agreus and Nomios could have been two different aspects of the prime Pan, reflecting his dual nature as both a wise prophet and a lustful beast.
