A music professor has identified a new portrait of Leonardo da Vinci. The 500-year-old engraving, if verified, will be only the third known portrait of the Renaissance Master created during his lifetime.

The engraving was created by Marcantonio Raimondi in 1505, and has resided at the Cleveland Museum of Art since the 1930s, but the figure in in the 500-year-old image, which can be seen playing an instrument called the lira da braccio, was long thought to depict the Greek mythological figure of Orpheus, a prophet and musician.
