The Portrait of a Musician is an unfinished painting by the Italian Renaissance artist Leonardo da Vinci, dated to c. 1483–1487. Produced while Leonardo was in Milan, the work is painted in oils, and perhaps tempera, on a small panel of walnut wood. It is his only known male portrait painting, and the identity of its sitter has been closely debated among scholars.
Perhaps influenced by Antonello da Messina's introduction of the Early Netherlandish style of portrait painting to Italy, the work marks a dramatic shift from the profile portraiture that predominated in 15th-century Milan. It shares many similarities with other paintings Leonardo executed there, such as the Louvre Virgin of the Rocks and the Lady with an Ermine, but the Portrait of a Musician is his only panel painting remaining in the city, where it has been in the Pinacoteca Ambrosiana since at least 1672. One of Leonardo's best preserved paintings, there are no extant contemporary records of the commission. Based on stylistic resemblances to other works by Leonardo, virtually all current scholarship attributes at least the sitter's face to him. Uncertainty over the rest of the painting arises from the stiff and rigid qualities of the body, which are uncharacteristic of Leonardo's work. While this may be explained by the painting's unfinished state, some scholars believe that Leonardo was assisted by one of his students.
