The Story
Edited and Annotated by Vincenzo De Risi. Translated by G.B. Halsted and L. Allegri
Saccheri's attempt to prove the Parallel Postulate is today considered the most important breakthrough in geometry in the 18th century, as he was able to develop for hundreds of pages and dozens of theorems a system in geometry that denied the truth of the postulate (in the attempt to find a contradiction).
