Risner was a student of Petrus Ramus and, as his successor, held the chair of mathematics at the Collège Royale de France in Paris. But a short time later he returned to his birthplace in Hersfeld. Important results of the collaboration between Ramus and Risner is the 1572 edition of two basic optical writings of the Arabic and Latin Middle Ages, namely the 'Opticae' by Ibn al-Haitam (Latin: Alhazen) and the 'Perspectiva' by Witelo. Risner's edition received a lot of attention and influenced Johannes Kepler in particular. The 'Opticae libri quatuor' was also created in collaboration with Ramus; the conception probably goes back to Ramus, while Risner worked out the details and the evidence. The main source of this writing was Witelo's 'Perspectiva'. Only the first book was fully worked out "(see NDB XXI, 646). Risner's 'Opticae libri quatuor' "later influenced Snell. It seems that the book was begun during the early years of Ramus and Risner's association; and it is probable that the basic outline was Ramus', while Risner was given the task of providing appropriate demonstrations and discussion . . . The work depends primarily on Witelo, although other ancient and medieval authors are also cited." (DSB). - Visit our website to see more images!.

[20], 259, [1 blank] pp.Rare work on optics and mathematics by Friedrich Risner (1533-1580), apprentice and colleague of Peter Ramus, the famous anti-Aristotelian humanist and educational reformer. The first edition appeared in 1606.Risner's mathematical abilities were highly praised by Ramus, who, in his will, even established a chair in mathematics at the Collège Royal de France with Risner as its first occupant. The first major result of the collaboration between Risner and Ramus was Risner's edition (1572) of two manuscripts discovered by Ramus: the first edition of Optics by Ibn al-Haytham (in Latin Alhazen), who worked at Cairo in the first half of the 11th century; and a greatly improved edition of Perspectiva by Witelo (in Latin Vitello), a Polish scientist of the second half of the 13th century. Alhazen's work preserved all that was known by the ancients in the field of optics, and Risner's edition and his own observations and corrections helped establish the science upon a new foundation. Risner's present Opticae, based partly on Witelo, appeared only posthumously, but was probably outlined by Ramus and further developed by Risner during the early years of their collaboration. It exerted a great influence on Snell and others.Badly browned, but otherwise in good condition, with an abrasion on the title-page and last text page (probably erasing a library stamp), not affecting the text. Re-backed and with some restorations to the boards.l VD17 12:159504X; cf. DSB 11, p. 468; Poggendorff II, col. 648; not in Honeyman; Houzeau-Lancaster.
