Ancient Metapontines

Little is known about his life or his beliefs, but he is sometimes credited with the discovery of the existence of irrational numbers. The discovery of irrational numbers is said to have been shocking to the Pythagoreans, and Hippasus is supposed to have drowned at sea, apparently as a punishment from the gods for divulging this and crediting it to himself instead of Pythagoras, which was the norm in Pythagorean society.

Brontinus of Metapontum (, also Brotinus, ; fl. 6th century BCE), Magna Graecia, was a Pythagorean philosopher and a friend and disciple of Pythagoras. Alcmaeon dedicated his works to Brontinus as well as to Leon and Bathyllus. Accounts vary as to whether he was the father or the husband of Theano.
