Euclid

The first important mathematician associated with Alexandria was Euclid (c.250 BC), who wrote on optics and conics, but is mainly remembered for his Elements. The most influential and widely read mathematical book of all time, the Elements is a compilation of results known at the time, and consists of thirteen books on plane and solid geometry, number theory, and the theory of proportion. A model of deductive reasoning, it builds from initial axioms and postulates, using rules of deduction to derive each new proposition in a logical and systematic order.
