Publius Ovidius Naso, known more commonly today as Ovid, originally composed his Metamorphoses in Latin and completed the work around 8 CE. The Metamorphoses combines hundreds of Greco-Roman mythological tales into 15 books of poetry, brief summaries of which follow.

This guide follows A. D. Melville’s 1986 translation for Oxford World’s Classics, and citations reference page numbers rather than line numbers. This guide follows Melville’s divisions of the various myths, although not all editions will make such divisions. This guide also discusses some potentially triggering topics, including violence, sexual violence, death, suicide, cannibalism, and enslavement.
