In the Bucolics and Georgics of Virgil we find frequent invocations to Pan as the god of shepherds, the guardian of flocks, and the inventor of the syrinx, or Pandean pipes.

Ipse, nemus linquens patrium, saltusque Lycæi,

Pan, ovium custos, tua si tibi Mænala curæ,

Adsis, O Tegeæe, favens.

Georg. i. 16-18.

God of the fleece, whom grateful shepherds love,

Oh, leave Lycæus and thy father’s grove;

And if thy Mænalus yet claim thy care,

Hear, Tegeæan Pan, th’ invoking prayer.

Georg. i. 16-18.
