"The Tariffa, perhaps the rarest of all Kircher's works and his least characteristic, is entirely mathematical" (Merill).
L'ouvrage le plus rare d'Athanase Kircher (1602-1680), le Tariffa propose de nombreuses solutions à des problèmes d'arithmétique et de géométrie. Le premier volume est essentiellement consacré à la trigonométrie, le second volume contient des tables pour faciliter les calculs vectoriels, des surfaces, et des formes géométriques. Le premier volume est richement illustré de 24 planches gravées sur bois.
"The Tariffa Kircheriana offered a detailed description of the miraculous Kircherian combinatorial art that would quickly allow all the princes and nobles of Europe - and presumably anyone else "occupied by more important business" who could read Latin - to master all of geometry and arithmetic. In fact, Kircher himself seems to have become exactly that sort of person by 1679 - at least this was how his associates described him rather than acknowledging that he was no longer capable of completing his own books. Kircher consigned the final preparation of the Tariffa to Benedetto Benedetti, professor of mathematics at la Sapienza, who described how "new occupations of great moment" had obliged Kircher to offer him the pri
