Dog in Rembrandt’s The Night Watch was copied from widely available book, suggests new research

New research suggests that the barking dog in the lower right corner of Rembrandt's *The Night Watch* (1642) was copied from a title-page illustration by the Dutch artist Adriaen van de Venne. Anne Lenders, curator of 17th-century Dutch paintings at the Rijksmuseum, recognized the resemblance while visiting an exhibition on Van de Venne at the Zeeuws Museum. Macro X-ray fluorescence scans of the painting's underdrawing confirmed the similarity, though Rembrandt modified the dog's posture and added a tongue to make it appear alert and barking at a drum.
