CLAVIUS, Christoph (1538-1612). Geometria practica. Rome: A. Zannetti, 1604.
4o (205 x 157 mm). Woodcut diagrams in text. (Some mostly marginal worming, occasionally catching letters, some pale browning and dampstaining.) Contemporary vellum (a bit worn and soiled). Provenance: some early marginalia, early inscription on front flyleaf.
FIRST EDITION. "Clavius states among other things a method of dividing a measuring scale into subdivisions of any desired smallness, which is far more complete than that given by Nonius and must be considered as the precursor of the measuring instrument named after Vernier, to which perhaps the name Clavius ought accordingly to be given" (Catholic Encyclopedia). Brunet II:92.
