Restitution of the Two Books on Plane Loci of Apollonius of Perga together with On Spheric Contacts by Pierre de Fermat (1601-1665)

Pierre de Fermat, the famous French Renaissance mathematician who gave us Fermat's Last Theorem, left no mathematical records so far as the English speaking world is concerned. This is because he wrote primarily in Latin. Here for the first time are some of his early works restoring the lost geometry treatise of Apollonius of Perga as well as Fermat's own expansion of plane loci into the third dimension using spheres.

This English translation is based on Paul Tannery's 1891 edition of The Works of Pierre de Fermat (Les Oeuvres des Pierre de Fermat) and includes 65 geometrical diagrams necessary to understand the test. This work is easily accessible to anyone with a basic knowledge of geometry and gives us a glimpse inside the mind of one the greatest mathematical minds in European history.
