## Geometriae Practicae Novae.

Nuremberg: Simon Halbmayer, 1627.

First complete edition and the first edition of the fourth part (the first part was published in 1616, the first three parts together in 1618). The first book is a treatise on general mathematics and the principles of geometry. The second deals entirely with techniques of surveying. The third part describes a surveying instrument (the 'mensula praetoriana') invented by the scientific instrument maker Johann Praetorius (Richter) and its application. The fourth part is in fact a German translation of Curzio Casati’s 'Geometricum problema' (1602). He shows himself to be particularly well acquainted with the contemporary Italian mathematical literature, giving in particular a resumé of some of the work of Pietro Antonio Cataldi: "The use of limited continued fractions in the expression of a relationship between large numbers is found in the 'Geometria practica' of Daniel Schweneter (1627), published soon after Cataldi’s death." (DSB, III, p.128). Cantor, Vorlesungen II, p.666-70; Zeitlinger/Sotheran, 2nd suppl, 2421; Poggendorff II 878.

Four parts in one volume. 4to: 200 x 154 mm. Contemporary vellum. With two engraved and two woodcut titles, and two engraved portraits. Some browning throughout. Liechtenstein book plate to front paste down and "Anno 1640" inscribed at top. (12), 296; (8), 198, (6); (12), 101, (3); 83, (5) pp.
