After the Greek philosopher Pythagoras about whom very little is known that isn't speculative. We are not even sure if Pythagoras' theorem can with any accuracy be attributed to him. He set up a religious sect in southern Italy and was the first of the Greeks to dub himself a philosopher. He believed that everything is related to mathematics and that numbers are the reality of which everything is made.
