About

GEOMETOR • durer is the scholarly Digital Scriptorium edition and exact symbolic engine for Albrecht Dürer’s Underweysung der Messung, mit dem Zirckel un[d] Richtscheyt, in Linien Ebnen unnd gantzen Corporen (Nuremberg, 1525; 2nd ed. 1538), collated with Joachim Camerarius’s 1532 Paris Latin translation Institutionum Geometricarum Libri Quatuor.

Historical Significance

Published in Nuremberg in 1525 and dedicated to his lifelong humanist friend Willibald Pirckheimer, Dürer’s Underweysung der Messung is the first printed mathematics book in the German language and the decisive bridge between two worlds:

1. Classical Greek Deductive Geometry (demonstrative): Euclid’s Elements, Archimedes’s spirals and semi-regular polyhedra, Apollonius’s conic sections, Nicomedes’s conchoid, and Plato/Sporus/Hero’s solutions to the Delian doubling of the cube.

2. Northern & Italian Workshop Practice (mechanice): Medieval stonemasons’ single-aperture compass traditions (Geometria Deutsch, Matthäus Roriczer, Abū al-Wafāʾ), Luca Pacioli and Leonardo da Vinci’s Divina Proportione (1509), Leon Battista Alberti and Piero della Francesca’s linear perspective, Vitruvian architecture and gnomonics, and Nuremberg punchcutting and calligraphy.
