Pythagoreans

Parmenides wrote about 470 B. C. He is represented as a serious and influential man, with a high moral character. He exercised strong influence upon such philosophers as Plato and Democritus, and was a political power in the city of Elea, of which he was a native. He was not a stranger to the Pythagoreans. The large fragment of his poem is the most ancient monument extant of metaphysical speculation among the Greeks.
