The first major Roman poet to begin his career during the reign of Augustus,[3] Ovid is today best known for the Metamorphoses, a 15-book continuous mythological narrative written in the meter of epic, and for works in elegiac couplets such as Ars Amatoria ("The Art of Love") and Fasti. His poetry was much imitated during Late Antiquity and the Middle Ages, and greatly influenced Western art and literature. The Metamorphoses remains one of the most important sources of classical mythology.[4]
