Manuscript Monday: LJS 232 – Trattato delle proportioni…

Dot Porter, Curator, Digital Research Services at the University of Pennsylvania Library, offers a video orientation to Penn Library’s LJS 232, Trattato delle proportioni et proportionalità by Benedetto Varchi. This manuscript was written in Italian in Florence, Italy, after 1539. It is a treatise by Benedetto Varchi on proportion as the basis for rithmomachia, a mathematical game played on a chessboard with pieces that each have a shape and a number; a dialogue written by Carlo di Ruberto Strozzi, in which Cosimo Rucellai, who introduced the game to Benedetto Varchi, teaches the rules to Strozzi and Jacopo di Piero Vettori.
