What We Know Now:

The Pythagorean theorem's attribution to the Greek philosopher represents mathematics' most famous miscredition. The legend suggests Pythagoras formulated the triangle relationship around 500 BCE through divine inspiration, with stories of sacrificing oxen to celebrate. This fits our preference for heroic individual achievement over collective knowledge.

Historical evidence reveals the theorem was widely understood centuries before Pythagoras. Babylonian clay tablets from 1800-1600 BCE show sophisticated understanding of Pythagorean triples. Ancient Egyptian surveyors used the 3-4-5 relationship to re-establish property boundaries after Nile floods.

Indian and Chinese mathematicians also documented the relationship centuries before Greek documentation. These civilizations used the principle practically without necessarily providing the generalized proof that became Pythagoras's contribution. The theorem's real history reveals how fundamental mathematical truths often emerge independently across civilizations.
