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.[1] The painting was later lost during the Papal attack on Monteriggioni, led by the Templar Cesare Borgia.[2]
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.[3]
Ezio eventually managed to steal the painting back.[3]
