upennmanuscripts: LJS 232 - Trattato delle proportioni et proportionalità This manuscript features: 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; other notes on the game. There are also later unrelated notes and pen trials on leaves before and after main texts. Unfortunately, this manuscript is often damaged and bled-through due to oxidation on many leaves. It was written in Florence after 1539.Do you want to know more? Click here! And here if you want to see the facsimile, or here for the video orientation.P.S.
