FIRST EDITION OF THE EARLIEST COMPREHENSIVE EUROPEAN WORK ON OPTICS, and the first work containing descriptions of medieval laboratory instruments. Witelo, Perspectiva, or Opticae libri decem, written ca. 1270 is a massive work that relies extensively on Alhazen as well as other ancient writers on optics. 'The most outstanding feature of Witelo's method was his combination of manual and technical skill with mathematics for quantitative experiments with instruments. An excellent example of the use of this combination in the construction of an instrument is his work on the parabolic mirror, with which Alhazen's writings as known in Latin showed no acquaintance, though Roger Bacon had understood its essential properties ... [He] made some admirably original observations on the more purely psychological aspects of vision. These related chiefly to direct perception and the effects of association and reasoning on vision, and such problems as illusions, visual beauty, and the perception of distance and size and of the third dimension of space" (Crombie Robert Grosseteste and the Origins of Experimental Science p. 218). Witelo's work, served as the standard reference work on optics and was not surpassed until the seventeenth century, influencing scientists such as Brahe, Kepler, Galileo, and Descartes.
