Euclide

Euclide, known in English as Euclid, was a Greek mathematician active in Alexandria during the 3rd century BCE. Very little is known about his life, and precise dates are uncertain. He is traditionally regarded as a prominent figure in Hellenistic mathematics, associated with the development of a systematic, axiomatic approach to geometry and number theory.

His most famous work is Elements (Stoicheia), a comprehensive treatise that compiles and organizes knowledge on

Beyond the Elements, Euclid is traditionally credited with other mathematical works, some now known only by

Euclid’s impact extends beyond mathematics: the axiomatic method he popularized influenced the philosophy of science and
