Crotone was in Theanus' time a colony of Magna Graecia.

Enheduanna (25th century BC) was a predecessor of Theano of Crotone. She is considered to be the first woman in the history of science and the first one to sign her work, in cuneiform; as well the Egyptian physician Peseshet or the Assyrian perfumers like Taputti, who paved the way for later women.

Some of Theano's contemporaries are other women in the Pythagorean school that were born around 500 BC, such as Damo, Myia and Arignote of Crotona, considered to be daughters of Theano and Pythagoras by several authors. Even though there is not much information about them, some other women belonging to this group were Babelica of Argos, Beo of Argos, Quilonis, Equecratia de Fliunte, Ecelo and Ocelo of Lucania, Habrotelia of Tarento, Cleecma, Cratesiclea, Lastenia of Arcadia, Pisirroda of Tarento, Fintis, Teadusa, Timica and Tirsenis of Sibaris. 

Following Theano, we can find Aglaonice (3rd century BC, known for her ability to predict eclipses) and Hypatia (4th century AD). 

Perhaps, the golden number is the first irrational number known by the Greeks. Irrational numbers are those having infinite non-periodic decimals, i.e. none of the decimal parts are repeated, as opposed to periodic decimals such as 10/3= 3.33. This contradicted some of the philosophy theories of the Pythagorean, since they linked mathematics with their philosophical vision of the world. That is why they decided to keep secret this discovery.
