An illustration by Stephan van Calcar in Vesalius’s De Humani Corpus Fabrica [http://en.wikipedia.org/wiki/De_humani_corporis_fabrica]. Vesalius grew up near Gallows Hill, an area where criminals were executed and left to rot. As a child, he would look at bodily structures and take bones apart. In his book,published in 1543, offered the first accurate information of human anatomy and began to expose the long-standing mistakes in Galen’s work. It was the first book of its kind as well!
