Jan de Doot is the subject of a painting from 1655 by Carel van Savoyen. It shows De Doot, a smith, holding in one hand a kitchen knife, and in the other a large bladder stone the size and shape of an egg, set in gold. This 17th-century Dutch blacksmith is said to have performed a successful lithotomy on himself in 1651. The painting is part of the Portrait Collection of the Laboratory of Pathology, which is part of the University of Leiden.
