Eudoxus of Cnidus (c. 408 – c. 355 BC) was an ancient Greek astronomer, mathematician and scholar who is considered by some to be the greatest of mathematicians in all Antiquity second only to Archimedes. Eudoxus was probably the source for most of book V of Euclid's Elements. His work on proportions became the basis for all quantitative work in science.
