FIRST EDITION TO INCLUDE DOPPELMAYR'S WORK ON FIELD MEASUREMENTS AND A VERY SCARCE MATHEMATICAL WORK, OCLC LISTS ONLY 9 INSTITUTIONAL COPIES, and there is no record of a copy sold at auction going back as far as the 1970s. This is the first edition to include valuable additional material by Johann Gabriel Doppelmayr, who was at this time professor of mathematics at the Aegidien-Gymnasium. Cantzler was an important 17th century cartographer and Trew contributed greatly to 17th century mathematics and astronomy. Item #27247
The first edition to include Doppelmayr's work on field measurements. Title-page in red and black, illustrated with an impressive allegorical frontispiece displaying a personified Mathesis standing triumphantly above regret, ignorance, difficulty and contempt. Also with 60 engraved plates, many of which are folding, displaying concepts, tools and techniques in the geometric and other related sciences, and with many more woodcut diagrams within the text. 8vo, in full contemporary vellum over stiff boards, the spine labeled in manuscript. [21ff], 514 pp. A handsome copy in fully original state, the first few leaves only with faint evidence of long-ago dampness, the front endpapers with extensive scholarly notes in an early hand.
