Presenter Waldemar Januszczak asks why is Rembrandt's painting, The Anatomy Lesson of Dr Tulp, so great. In the 17th century, the Dutch developed a passion for public dismemberment. Dissections became a public event that would last from three to five days. Born in 1609 and moving to Amsterdam in 1631, Dr Tulp was an ambitious man who commissioned the newly arrived Rembrandt to paint this picture of one of his anatomy lessons mounted in 1632 by the Surgeons' Guild. The painting made Rembrandt's reputation and he went on to paint some of Amsterdam's finest people.
