This volume is a rare edition in Dutch of the greatest of the anatomical 'flap' books. The work features three full-page plates with dozens of detailed anatomical illustrations superimposed so that lifting the layers shows the anatomy as it would appear during dissection. Although flaps had been used in printing before, Remmelin was the first to use them on this scale. Eight prints of the plates were produced then cut apart and pasted together to form the layers. The first authorized edition was printed in Latin in 1619 with the title Catoptrum Microcosmicum. The plates were printed in 1613, and the text without the plates was printed the following year, both without the consent of the author. Although Remmelin's work was very popular and went through a number of editions, the format of the flaps was very delicate and not practical for the dissection room. Copies such as this one with all of the flaps intact are very rare. (Text from the NLM website)
