Zurich, Switzerland: J. J. Bodmer, 1646. Second edition. Hardcover. Quarto (4to). Very good- condition. Item #012620
Lacks the title page and 8 pages of plates, including some fold-outs. [viii], 308 leaves. Original full vellum binding is stained and soiled, with wrinkling to front board, with the fore-edge vellum loosened. This is the revised and enlarged second edition of one of the earliest and most comprehensive German handbooks on land surveying. Swiss mathemetician Arduser (1584-1665) discusses the theoretical problems of Euclid's geometry and offers detailed descriptions of two surveying instruments. He includes instructions on how to build and operate them: a clinometer with horizontal compasses and Galileo's newly invented "instrumentum partium" which is carefully depicted in one of the unfortunately lacking plates. The text contains over 100 woodblock illustrations and diagrams, and 19 two-thirds or full page woodcuts. Minor staining to bottom edge of pages, affecting the margin only. Title continues "...sich im bawen, feldmassen vnd visieren zu uben begeren, zu nutz und gefallen beschriben, und jetz von newem vmb zwey Bucher vermehrt."
