Oronce Fine's Geometry

These are the opening pages of the section of the geometrical work of Oronce Fine (1494-1555) dealing with Euclid's work on circles. This section, in turn, was part of the geometry section (1530) of Fine's major work entitled Protomathesis (1532), which covered arithmetic, astronomy, and astronomical instruments, as well as geometry.  The pages displayed give a somewhat theoretical treatment of geometry, but Fine went on to such practical matters as measuring length, height, surface area, and volume.

Convergence also has on display as a "mathematical treasure" images of three more pages of the Protomathesis: the title page, frontispiece, and a page on using a quadrant to measure depths. These images are from the Lehigh University Linderman Library's Special Collections.
