The “Muscle Men” have been created in true Renaissance style in De Humani Corporis Fabrica Libri Septem. Vesalius and Calcar excelled in elevating medical illustration into an art form. The muscle men illustrations can be found in Liber II (book 2) of the Fabrica, between pages 170 and 208.
The Fabrica is considered one of the most important medical books ever published, and changed the way that anatomy was understood and taught.
