This painting, acquired as by Aert de Gelder, has for decades been assigned either to Rembrandt's cousin Karel van der Pluym (1625–1672), or to Heyman Dullaert (1636–1684), a Rotterdam poet and painter who was Rembrandt's pupil in the early 1650s. The connection with Dullaert is encouraged by Arnold Houbraken's reference (1721) to a canvas by Dullaert, The God of War Mars in a Reflecting Cuirass, that was sold as a Rembrandt in Amsterdam. However, the subject was fairly common (e.g., the famous Man in the Golden Helmet in Berlin, now attributed to an unknown Rembrandt pupil), and the present picture has little in common with Dullaert's few surviving works. Its style and subject do recall several paintings by Van der Pluym, though most of them are of lesser quality.
