One folding engraved plate.  pp. Small 4to, attractive modern marbled boards, leather lettering-piece on spine. Augsburg: D. Francken, 1610. First edition and very rare. Faulhaber (1580-1635), a teacher of mathematics at Ulm and a friend of Kepler, made his most lasting accomplishments in the dissemination and explanation of the logarithmic method of calculation. One of Faulhaber's school's most famous pupils was Descartes, who studied there in 1620 (see William R. Shea's The Magic of Numbers and Motion. The Scientific Career of René Descartes, pp. 102-07). This is Faulhaber's second book and caused him considerable problems with the city's municipal council, as it was published without the permission of the office responsible for supervision of the schools. This book describes a surveying instrument invented by Daniel Speckle in the Netherlands. The fine plate depicts the semicircular instrument, which is divided into 220 parts. Fine copy, preserved in a box. ❧ D.S.B., IV, pp. 549-53. Poggendorff, I, 725. Tomash & Williams F23. (Inventory #: 6760)
