Publius Ovidius Naso, known to modern readers as Ovid, was a Roman poet, well-versed in mythology of the Greco-Roman world. Many Roman gods or figures corresponded almost identically with Greek gods or characters, and Ovid treats them all as part of the known world. His most famous work is probably the Art of Love. Metamorphoses cemented his reputation as a prime source for legends and mythology, and his works lay behind many Medieval and Renaissance stories. Late in life, he was exiled by Augustus Caesar, as he was finishing the Metamorphoses (The Changes).
