In Roman mythology, Vertumnus (; also Vortumnus or Vertimnus) is the god of seasons, change and plant growth, as well as gardens and fruit trees. He could change his form at will; using this power, according to Ovid's Metamorphoses (xiv), he tricked Pomona into talking to him by disguising himself as an old woman and gaining entry to her orchard, then using a narrative warning of the dangers of rejecting a suitor (the embedded tale of Iphis and Anaxarete) to seduce her. The tale of Vertumnus and Pomona has been called the only purely Latin tale in Ovid's Metamorphoses.
Vertumnus' festival was called the Vertumnalia and was held 13 August.
Vertumnus is a painting by Mannerist painter Giuseppe Arcimboldo produced in Milan c. 1590-1591. The painting is Arcimboldo's most famous work and is a portrait of the Holy Roman Emperor Rudolf II re-imagined as Vertumnus, the Roman god of metamorphoses in nature and life; the fruits and vegetables symbolize the abundance of the Golden Age that has returned under the Emperor's rule.
