Portrait of a Musician

Leonardo da Vinci's Portrait of a Musician was a depiction of the an unidentified man.

Painted 1490, the painting was eventually purchased by the Ezio Auditore da Firenze and placed in the gallery at the Villa Auditore. The painting was later lost during the Papal attack on Monteriggioni, led by the Templar Cesare Borgia.

Five years after the attack on Monteriggioni, in 1506, Ezio Auditore - whilst looking for a now-kidnapped Leonardo - learned that the Portrait of a Musician held part of a map identifying the location of the Temple of Pythagoras, and that the painting now was in the possession of a man named Patrizio, an old flame of Lucrezia Borgia, who intended to sell it to Ercole Massimo.

Ezio eventually managed to steal the painting back.
