in Roman mythology, was a god of very doubtful significance, of whom nothing certain is known save that in Rome, where the Tuscan street leads to the Forum, his statue was erected; and that a feast, Vertumnalia, was held on Aug. 27 in honor of him; also that Pomona, the goddess of fruit, was thought to have been his wife. Some call him god of the seasons, others god of trade; some say he came from the Tuscans, others from the Sabines.
