“ Buzjani's Heptagon”


Digital print, 13" X 13", 2007.



This print was inspired by Abu’l-Wefa Buzjani's (10th Century Persian mathematician) construction of a regular heptagon contained in his treatise, “On Those Parts of Geometry Needed by Craftsmen”. His construction is illustrated by the linework in the center portion of the print. The characters around the perimeter of the design repeat Buzjani’s name in Farsi.
