Mathematical Treasure: Fermat’s Varia opera mathematica

Author(s): 
Frank J. Swetz (The Pennsylvania State University)

The French mathematician Pierre de Fermat (1601–1665) is best known for his “Last Theorem,” proved in 1995 by Andrew Wiles, but he also made contributions to other aspects of number theory, the foundations of the calculus, and analytic geometry. For various reasons, including long periods of civil unrest in his relatively isolated home of Toulouse, many of Fermat’s results were not published until after his death. In particular, this 1679 volume was the first effort to bring together his significant works as well as his mathematical correspondence.

Much of the work recorded in Varia opera mathematics fits within the prehistory of the calculus.
