<P> Euclid ( / ˈjuːklɪd / ; Greek : Εὐκλείδης Eukleidēs ( eu̯. klěː. dɛːs ) ; fl. 300 BC ) , sometimes given the name Euclid of Alexandria to distinguish him from Euclides of Megara , was a Greek mathematician , often referred to as the `` founder of geometry '' or the `` father of geometry '' . He was active in Alexandria during the reign of Ptolemy I ( 323 -- 283 BC ) . His Elements is one of the most influential works in the history of mathematics , serving as the main textbook for teaching mathematics ( especially geometry ) from the time of its publication until the late 19th or early 20th century . In the Elements , Euclid deduced the theorems of what is now called Euclidean geometry from a small set of axioms . Euclid also wrote works on perspective , conic sections , spherical geometry , number theory , and rigor . </P>
