FIRST EDITION. A FINE COPY IN A CONTEMPORARY GERMAN BINDING. Witelo (or Vitellio), of Silesia, wrote his treatise on perspective in the 1270s. The first book contains the mathematical principles required to understand perspective, designed to supplement Euclid's Elements
, and the remaining nine books on optics and perspective were based primarily on Alhazen, though Witelo shows his familiarity with other mathematical sources. It was a very influential text, becoming a university textbook alongside Alhazen, and was a considerable influence on practical perspective in art as well as among scientists, until Kepler's Ad Vitellionem paralipomena
of 1604 rewrote the science of optics while acknowledging his debt to Witelo.
The roll-tooled border has been connected with the binder Wenzel Dörffler (active 1561-1581; Haebler I 273) and with a Cologne binder, but neither of these is considered correct. The watermark in the pastedowns is similar to Briquet 5006 and 5007 (a tall crown containing a star), variants of which were common across Germany from the 1520s onwards.
