The geometrical curve, ’Witch of Agnesi’, has been named after Maria Gaetana Agnesi. Originally, the Latin name of the curve was ‘versoria’. However, in Italian it became ‘versiera’, which also means devil. Agnesi had talked about the curve in length in her book ‘Instituzioni analitiche ad uso della gioventù italiana’.

Maria was actually a very shy and private person. Some time now, she decided to join the church.

In 1739, Maria came across ‘Traité analitique des sections coniques’ of the Marquis Guillaume de l'Hôpital and became interested in mathematics. From 1740, she began to be guided by Father Ramiro Rampinelli, who later became professor of mathematics at the University of Pavia. With him, she studied differential as well as integral calculus.

In 1748, on the advice of Rampinelli, she published ‘Instituzioni analitiche ad uso della gioventù italiana’ (‘Analytical Institutions for the Use of Italian Youth’), in two big volumes. It was a text book on mathematics and some believe it was aimed educating her younger siblings.
