Varia Opera Mathematica
EXTREMELY RARE FIRST EDITION of Fermat's Collected Works, containing the first publication of most of his work. "Fermat shares with Descartes the innovation of analytical geometry by applying algebra to geometry. He, independently, represented a curve by an equation defining its characteristic properties. He published little but, in the manner of his times, announced his discoveries in letters to other mathematicians. Among his discoveries was a general method of solving questions of maxima and minima, a method he used in 1629 and one in use today. He contributed basic concepts in the theory of numbers and probability. The above [Varia Opera], published after his death, first presented his work and correspondence" (Dibner 108). Provenance: the Inner Temple Library, with small ink stamp on title and a few other leaves; English mathematician Francis Maseres's (1731-1824) copy with his signature on front flyleaf and annotations in text. Folio, contemporary calf rebacked. With five engraved folding plates; engraved head and tailpieces, diagrams in text. Scarce portrait not present, as often. Occasional light browning and foxing. A very good copy.
