Babylonian scribes listed Pythagorean triples a thousand years before Pythagoras

A single Old Babylonian tablet, Plimpton 322, records sets of whole numbers that satisfy a-squared plus b-squared equals c-squared, arranged in a systematic table. It was written more than a thousand years before the Greek thinker whose name is now attached to that relationship was even born.

How we know

Plimpton 322 dated to the Old Babylonian period, c. 1800 BCE (range 1800-1600 BCE); Pythagoras born c. 570 BCE. Gap: 1800 - 570 = ~1,230 years.
