Mathematical Treasure: Anonymous Practica geometriae

Frank J. Swetz (The Pennsylvania State University)

A brief manuscript entitled Practica geometriae was written in the latter part of the 13th century. Note the extensive marginal illustrations obviously added by a second author. Folios 41r, 41v, and 42r from this manuscript are shown. The entire manuscript consists only of folios 41r – 46v of the British Library’s Harley Manuscript 1.

The images above were obtained through the courtesy of the British Library. Each item may be examined in its entirety in the Library’s digital collection under the given reference.
