The Metamorphoses is a a Latin narrative poem in fifteen books by Publius Ovidius Naso (43 BC-17/18 CE), better known in English as Ovid. The theme of transformation unites a disparate collection of legendary stories which progress from the beginning of the universe to the deification of Julius Caesar. In some tales, however, the metamorphosis is a minor element in the story, leading many scholars to look for other interpretations of the poem.
Notable English translations in the public domain include the 1567 edition of Arthur Golding, the version known to Shakespeare, who mentions no classical poet in his works except for Ovid; an edition by George Sandys in the 1620s, and the 1717 edition of Sir Samuel Garth, whose translators included John Dryden, Joseph Addison, Alexander Pope and William Congreve as well as Garth himself.
