Portraits of individuals and groups represent almost two-thirds of Rembrandt’s oeuvre. This painting is an outstanding example of the artist’s late style and is the second-last portrait he made, only two years before his death. Although advanced in age, Rembrandt here is still experimenting with technique and form. The sitter’s right hand is cropped, symbolic of a life beyond the picture frame, and his pose is dynamic. Rembrandt has also used the sharp end of his brush to gouge the paint in the sitter’s hair, which adds to the lively appearance of this yet to be identified subject.
