Which Roman god of the woods and fields was identified with the Greek Pan? Faunus was the Roman god most often identified with Pan.
Faunus was an old Italian deity associated with forests, open countryside, fields, shepherds, and fertility in livestock. Roman writers also portrayed him as an oracle who could reveal the future through dreams or mysterious voices. In some legendary accounts, Faunus was a king of Latium who became divine after death.
The identification with Pan developed through interpretatio Romana, the Roman habit of equating their gods with familiar Greek deities. Pan was the Greek god of the wild, shepherds, flocks, and rustic music, so the pairing was natural. Later Roman art often gave Faunus Pan-like horns and goatish features.
Silvanus is an easy mix-up because he too was connected with woods and boundaries, but he was not the standard Roman equivalent of Pan. Priapus was chiefly linked with fertility and gardens, while Vertumnus governed seasonal change and plant growth. Faunus was honored at the Faunalia, celebrated on February 13 and December 5.
