Vertumnus was the god of seasonal change, of the turning year, of the metamorphoses by which one form of vegetation succeeded another (his name from verto, "to turn"). He was an Etruscan deity in origin (his Etruscan name was Voltumna, the chief god of the Etruscan league, in whose sanctuary at Volsinii the Etruscan twelve-cities held their council); he came to Rome with the Etruscan absorption and was Romanized as the god of the orchard's seasonal succession and of all transformations. He had a statue in the Vicus Tuscus near the Forum, and his festival the Vertumnalia was on August 13.
His principal narrative — the wooing of Pomona — is told under her entry above; the rest of his mythology was sparse. His shape-shifting capacity was his distinctive attribute, and the Latin poets used him as the type of the changeable: Propertius's fourth book contains a poem in which Vertumnus speaks in his own voice and lists the many forms he can assume. As a god of change, he was a natural patron of merchants whose fortunes turned with the seasons; he received small offerings from such people in his shrine.
