What was discovered

Systematisation of Greek geometry and arithmetic in thirteen books deduced from definitions, postulates and common notions. It fixed the model of what a proof is and was the most used textbook in history.

The fifth postulate (on parallels) was questioned since antiquity, and its independence was only proved in the 19th century.

What it led to

  • the axiomatic method
  • non-Euclidean geometry (through the fifth postulate)
  • Hilbert's Grundlagen
  • number theory
