Mathematical Treasures - Robert Recorde's Pathway to Knowledge

This is the first page of Pathway to Knowledge by Robert Recorde (1510-1558).  The book is essentially a version of Euclid's Elements, with commentary by Recorde to make it easier to understand.  On this page are Euclid's first three postulates, that one can draw a line between any two points, that one can extend a straight line, and that one can draw a circle with a given center and a given radius.
