Catoptrum microcosmicum [German], by Johann Remmelin. Ulm: Printed by Johann Schultes Buchtrucker, published by Johann Görlin Buchhandlers, 1661. [FOLIO QM21 .R45 1661], John Martin Rare Book Room, Hardin Library for the Health Sciences, University of Iowa Libraries.

From co-curator Damien Ihrig:
This book is one of my, admittedly many, favorites in the John Martin Rare Book Room (JMRBR) collection and this exhibit. Earlier works had incorporated flaps of various kinds to demonstrate layers of anatomy; however, Remmelin was interested in creating a complete anatomy using flaps. His Catoptrum microcosmicum was originally published in 1619 (also in the JMRBR collection) and included nearly 120 flaps (although a version of this book was initially published in 1613 by a printer friend of his, even though Remmelin did not think the book was ready). Interestingly, Catoptrum microcosmicum demonstrates a moral conflict with the presentation of bodies, adding modesty flaps, sometimes in multiple layers, over genitalia.
