 Roman poet Virgil compares the mourning of Orpheus for Eurydice to the "lament of the nightingale".While Ovid's retelling of the myth is the more famous version of the story, he had several ancient sources on which to rely before he finished the Metamorphoses in A.D. 8.Many of these sources were doubtless available to Ovid during his lifetime but have been lost or come to us at present only in fragments.
