PAN was the god of shepherds and hunters, and of the meadows and forests of the mountain wilds. His unseen presence aroused panic in those who traversed his realm.

Pan idled in the rugged countryside of Arkadia (Arcadia), playing his panpipes and chasingNymphs. One of these,Pitys, fled his advances and was transformed into a mountain-pine, the god’s sacred tree. Another, syrinx, escaped but was turned into a clump of reeds from which Pan crafted his pipes. And a third,Ekho (Echo), was cursed to fade away for spurning the god, leaving behind just a voice to repeat his mountain cries.
