The Metamorphoses is a Latin narrative poem by the Roman poet Ovid, considered his magnum opus. Comprising fifteen books and over 250 myths, the poem chronicles the history of the world from its creation to the deification of Julius Caesar within a loose mythico-historical framework. Although meeting the criteria for an epic, the poem defies simple genre classification by its use of varying themes and tones. Ovid took inspiration from the genre of metamorphosis poetry, and some of the Metamorphoses derives from earlier treatment of the same myths; however, he diverged significantly from all of his models. One of the most influential works in Western culture, the Metamorphoses has inspired such authors as Dante, Boccaccio, Chaucer, and Shakespeare. Numerous episodes from the poem have been depicted in acclaimed works of sculpture and painting by artists such as Titian. Although interest in Ovid faded after the Renaissance, towards the end of the twentieth century there was a resurgence of attention to his work; today, the Metamorphoses continues to inspire and be retold through various media. The work has been the subject of numerous translations into English, the first by William Caxton in 1480.
