Euclid, a Hellenist living in Alexandria, Egypt publishes Elements, a 13–volume treatise on geometry and the ancient Greek version of number theory.
Euclidean geometry employs, among other components:
– definitions
–postulates (axioms: highest level “laws”);
–propositions (theorems derived from postulates);
–proofs of theorems.
Euclidean geometry is a self–contained construct of mathematical and formal logic of elegance and perfection.
Elements has been revised in over 1,000 editions, and is considered the most successful “textbook” ever written.
