His axiomatic method shaped mathematical reasoning and philosophical approaches to demonstration for over two millennia, influencing thinkers from Aristotle to Spinoza.
Authored the Elements, systematizing geometry through axiomatic deduction
Formulated Euclidean geometry and the five postulates
Proved the infinitude of prime numbers
Developed the Euclidean algorithm for finding greatest common divisors
Established the axiomatic method as a model for rigorous reasoning
