Archimedes of Syracuse, probably known best for his invention, the Archimedes screw, provided an approximation of the ratio of a circle's diameter to it's circumference around 300 B.C. He did this by approximating a circle as a polygon with an infinite number of sides. When the polygon had 96 sides each, he calculated the lengths of their sides and showed that the value of pi lay between 31⁄7 (approximately 3.1429) and 310⁄71 (approximately 3.1408), consistent with its actual value of approximately 3.1416.

The greek letter Pi was given to Archimedes' ratio by William Jones in 1706. Ludolph van Ceulen had provided an approximation to this number accurate to 30 digits around the year 1600.
