VD 17 32:701326B (1 of 2 variants); NLM/Krivatsy 11945; Sommervogel VIII, p.198; Wellcome V, p.292; Becker, Collection of ophtalmology, 378. RARE FIRST EDITION, this copy in the variant with the dedication to György Szelepcsényi, Bishop of Esztergom. Treated in three books are optics, catoptrics and dioptrics, further the manufacture of optical devices with corresponding illustrations. Published in the same year that Isaac Newton was making his great advances in the study of light, this encyclopedic and lavishly illustrated book is a classic on optics, combining both physical and physiological optics. The anatomy and physiology of the eye and the physical properties of light are extensively treated. There is a great deal of historical information about the development of the optical science from Aristotle to the work of his contemporaries such as Kepler, Kircher, Aguilon and Scheiner. (see Becker). There are quite a number of 17th century books in which the theory of the Camera Obscura is explained (Kircher, Schott a.o.), but Traber's work arguably explains this invention best and illustrates it with some striking plates. Scheiner's apparatus for the observation of sun-rays and several types of the Camera Obscura are illustrated on the finely engraved plates. Zacharias Traber (1611-1679) was an Austrian Jesuit who taught mathematics in Vienna. - Visit our website to see more images!
