This great amount of variation, some of which obscures the original Platonic form of each polyhedron, demonstrates the theory of the time that all the variation seen in the physical world comes from the combination of these basic elements. Following these chapters, additional engravings depict additional polyhedral forms, including

artist, based on drawings by Jamnitzer. As Jamnitzer describes in his prologue, he built models of polyhedra out of paper and wood and used a mechanical device to help trace their perspective. This process was depicted in another engraving by Amman from around 1565, showing Jamnitzer at work on his drawings. Amman included this engraving in another book, ''Das Ständebuch'' (1658).


Related works

A later work on perspective, ''Artes Excelençias de la Perspectiba'' (1688) by P. Gómez de Alcuña, was heavily influenced by Jamnitzer. A 2008 German postage stamp, issued to commemorate the 500th anniversary of Jamnitzer's birth, included a reproduction of one of the pages of the book, depicting two polyhedral cones tilted towards each other. The full sheet of ten stamps also includes another figure from the book, a skeletal icosahedron. A French edition of ''Perspectiva corporum regularium'', edited by Albert Flocon, was published by Brieux in 1964. Gutenberg Reprints republished it both in the original German and in the French edition in 1981. A Spanish translation of ''Perspectiva corporum regularium'' was published in 2006.
