PEURBACH, Georg von (1423-1461). Quadratu[m] Geometricu[m] praeclarissimi Mathematici Georgii Burbachii. Nuremberg: Johann Stuchs, 1516.
First edition of this paper on Peurbach's long distance measuring instrument. The Austrian astronomer describes 'an instrument made up of an open square with two graduated sides and a pointer and sight attached to turn on the vertex opposite the graduated sides. The instrument is used for measuring altitudes of heavenly bodies or objects on earth and, by taking measurements from different positions, for determining the distance of inaccessible objects on the earth' (DSB). Rare: only one other copy traced at auction in the past 40 years (ABPC). Adams P-2270; USTC 688980; VD16 P-2054.
Folio (302 x 202mm). 10 leaves, printed in red and black, numerous woodcut diagrams and a large cut of Peurbach's device repeated on A2v (occasional light staining). Disbound. Provenance: Innsbruck, Christoph Wilhelm Putsch (1542-1572, inscription on title dated 1558) – Schweinfurt, Otto Schäfer (monogram stamp, bought in 1966).
