Abstract
Anatomic teaching has long informed surgical knowledge, experience, and skills. One tool for teaching that emerged during the Renaissance was the fugitive anatomic sheet, which used flap layers to reveal different levels of anatomy. In 1538, Vogtherr introduced the first fugitive sheets, which included illustrations of male and female figures with a torso paper flap that, when lifted, revealed the internal organs in a cartoonish style. The popularity of these anatomic fugitive sheets spurred an increase in small print-and-sale workshops. In 1543, Vesalius included fugitive anatomic sheets in his books Fabrica and Epitome , containing large paper flapped models that could be created by cutting out and gluing images of human internal anatomy onto a base layer. Students could tack these manikins up to a nearby wall during dissection. Significant collaboration between Vesalius and his publisher occurred to coordinate the integration of large foldable sheets featuring the cutout models into his works. Vesalius's groundbreaking discoveries, his use of the most advanced printing techniques, and his innovative teaching style are fundamental aspects of the legacy of medical education. This article shows these remarkable fugitive anatomic sheets from the original publications of Fabrica and Epitome together for the first time. It explores the innovative concepts and applications of Vesalius's unique printings.
