(24),303.(1) pp. and 4 folded engraved plates. With notes on front free endpaper in a contemporary hand. First edition of this importent work on Dioptrics. The work is dedicated to Euler, who wrote his famous work "Dioptrica" from 1769-71. Klügel continued and improved Euler's work, making some importent corrections.Klügel became professor in mathematics at Helmstadt. His extensive work in mathematics - e.g. Lambert, one of the outstanding forerunners of non-euclidean geometry, expressly referred to Klügel, who is also cited by most later critics of the problem of parallel lines - and physics began then and increased after his transfer to the chair of mathematics and physics at the University of Halle. His works included papers, textbooks, and handbooks on various branches of mathematics. (DSB VII:405). - Poggendorff I:1277. [Attributes: First Edition; Hard Cover]
