Johann Zahn (1641-1707).
Oculus artificialis teledioptricus sive telescopium. Nuremberg: Johann Christoph Lochner, 1702.
Second edition of Zahn’s treatise on the microscope and the telescope. The work is particularly valuable for its illustrations of both simple and compound microscopes of the period, including the type of compound instrument used by Robert Hooke. It contains many descriptions and diagrams, illustrations and sketches of both the camera obscura and magic lantern, along with various other lanterns, slides, projection types, peepshow boxes, microscopes, telescopes, reflectors, and lenses. The number of folding/double-page engravings varies among copies; the Burndy copy contains 6, while the Wellcome copy contains 4, as here. Cf. first edition: Garrison and Morton 263: 'includes the first complete history of early microscopes'; NLM/Krivatsy 13208; Norman 2278.
