Spheres of Pythagoras
Theano 6th Century BCE
The Pythagorean school was as much a Sisterhood as a Brotherhood. Theano of Crotona was a philosopher, physician, astronomer and mathematician. Along with her three daughters, she was a student of Pythagoras and was one of the most celebrated of the Pythagoreans. Theano later married Pythagoras and directed his school after he died with her sons, Arimnestes and Telauges. Although Pythagoras did not write his own teachings down, Theano was known through her many written works on cosmology, virtue and mathematics. Theano’s most important treatise was on the principle of the Golden Mean.
