The Physician ("Doctor Studying a Bottle") is a 1653 oil painting by Dutch Golden Age artist Gerrit Dou, and is now part of the Christchurch Art Gallery.
It exists in two versions: one (oil on copper sheet) in the Christchurch Art Gallery[1] and the other in the Kunsthistorisches Museum.
[2] The artwork is a typical Leiden fijnschilders Dutch style "niche painting" of the 17th century.
It depicts a figure (the physician) holding a bottle of orange liquid up to the light.
The relief below the window of children by Francois Duquesnoy was one that Dou repeated for many of his “niche paintings.” This article about a seventeenth-century painting is a stub.
