Sfortunati, G. Nuove lume. Libro de arithmetica... Con uno breve trattato di geometria. Venedig, G. & P. Nicolini da Sabio, 1545. 4to (21:16 cm ). Mit einigen Holzschnittdiagrammen. 129 num. Bll. , 1 w. Bl. Hldr. d. 19. Jh. , etwas berieben. ( ) Adams S 1042; Hoock-J. S20.4; Riccardi I/2, 453; Smith, Rara 177. - Wohl dritte Ausgabe, bis auf Titel- u. Schlußblatt identisch mit der Erstausgabe von 1534, eine bei Smith aufgeführte Ausgabe von 1543 ist nicht nachweisbar ( 2. A. 1544). "Lo Sfortunato, il cui nome figura nella famosa quistione fra Cardano e Tartaglia, viene meritamente noverato tra i migliori autori aritmetici del principio del secolo decimosesto" (Riccardi). - Recht breitrandig, teilw. etwas braun- oder fingerfleckig, vereinzelt hs. Marginalien. Titel mit Besitzvermerk "Hippolito Biotti", dat. 1694 ( teilw. gestrichen). Probably third edition (first 1534, second 1544, the 1543 edition seems to be a ghost). "Sfortunati wrote his treatise along the lines followed by Borghi and Feliciano... His work is fairly complete as to the operations with integers and fractions, and is satisfactory as to the examples illustrating the Italian business life of the sixteenth century. The treatise closes with some work in practical mensuration and some mercantile tables" (Smith). - Some marginal thumbing and staining, a few marginal ink annotations. A copy with good margins, bound in 19th cent. half-morocco, somewhat rubbed.
