The Mauritshuis museum in The Hague has reclassified three paintings previously attributed to Rembrandt as copies or studio works: *Portrait of Rembrandt with a Gorget* (ca. 1629), *Study of an Old Man* (ca. 1655–60), and *‘Tronie’ of an Old Man* (ca. 1630). The first was identified as a copy in 1999, the second was found to be by a student despite a genuine signature, and the third may have been painted by a student or Rembrandt himself. The museum now lists 11 works as authentic Rembrandts, including *The Anatomy Lesson of Dr. Nicolaes Tulp* (1632), and seven works whose authenticity has been questioned.
This matters because it reflects the ongoing scholarly rigor in Old Master attribution, where technical analysis and connoisseurship can overturn long-held beliefs. The reattributions affect the market value and historical understanding of these works, and the museum has incorporated the research into a new exhibition titled “Rembrandt?,” on view until July 13. Such revisions are common in museums with major collections and underscore the importance of provenance and scientific examination in art history.
