 sm. 4to. sewn, uncut (portrait wanting and title and last 1. soiled) ; RARE, 1.1* 



Printed by James Young, 1645 



An extraordinary work, and interesting as having been influenced by Napier's discoveries. It is written in the' fanciful 

 language that might be expected from the translator of Rabelais, and is mathematically perhaps most interesting for 

 trying to create fresh though impracticable symbols.

The first Continental translation of Napier's Rabdologia (</. v. ante). It is very rare and was unknown to Pog^endorff, 

 Kastner, and Montucla. The imprint is interesting as an early use of the name Berlin at a time when according to 

 M. Deschamps and other bibliographers the city was called Friedrichsstadt.

 with diagrams 2 vols. sm. 4to. in 1, old Italian vellum (RARE), 1. Is Romce, 1604-6 



FIRST EDITIONS of both works. They were reprinted in 1660 and 1661 respectively. The first gained the admiration of 

 Galileo, who found it so much superior to his own researches in Discorsi e Demostrazioni, that he decided not to 

 continue his investigations on the subject. 



Valerio was a member of the Accademia de' Lincei, but expelled from it in 1616 for publicly declaring Galileo a follower 

 of Copernicus.
