Theano is considered by some to be the first known woman mathematician. Based on the works that have survived, it is thought that she worked on The Golden Mean and The Golden Rectangle. While her exact life story remains unknown, she is believed to be either the student or wife of Pythagoras, and sometimes both. Most agree that she was his wife and that they had several children together. It wouldn’t be unheard of for a mentor to become romantically involved with their student, especially with someone as smart and as talented as Theano. In Pythagorean Society, women had more of a chance to be treated as equals to their male counterparts. It is possible that over time, Western society and patriarchal forms of thought have pushed Theano’s work back in terms of accreditation and importance. Through time, especially in places that are predominantly Christian, their bias towards women and especially women scholars bleeds into their research. It is also considered that the patriarchal society in the larger portion of ancient Greece led to blatant sexism in all aspects of discovery, going back as far as the earliest philosophers. The work and discovery that Theano did alongside Pythagoras is a great example of the Matilda Effect, wherein the work of women is attributed to their more successful male colleagues. This can be due to many unrelated reasons, although most can be prescribed to societal and cultural values of the researchers at the time of their historical work.
