The National Gallery in London is about to open an exhibition called 'Dutch Portraits: the age of Rembrandt and Frans Hals'. The reason I'm flagging it up here is that it includes one of the most famous medical portraits of all time: The Anatomy Lesson of Professor Nicolaes Tulp. The odious showman anatomist Gunther von Hagens models himself on Tulp. You can read more about the painting here and here. The exhibition runs from 27 June to 16 September 2007.
