**Tommaso Ceva** He was an Italian Jesuit mathematician, poet and priest. He was born in the city of Milan on December 20, 1648 and died on February 2, 1737. Although less well known than his brother Giovanni Ceva (from which the term "ceviana" comes from), he was also brilliant mathematical and physical.

In mathematics, he studied arithmetic, geometry and gravity, publishing the work *Opuscola mathematica* (1699). This work, together with a brief treatise proposing a new method for the division of angles, was reviewed in *Acta Eruditorum*, a German monthly scientific journal that was published for 100 years (between 1682 and 1782), founded in Leipzig by Otto Mencke and Gottfried Wilhelm Leibniz.

Tommaso Ceva was a professor of mathematics and rhetoric at Brera College in Milan. He was the interlocutor of a famous mathematician of the time, Guido Grandi, with whom he exchanged nearly five hundred letters. One of his students was Giovanni Gerolamo Saccheri, a Jesuit priest and Italian mathematician who was the first to demonstrate non-Euclidean geometry theorems.

As a poet Tommaso Ceva wrote the Latin poem *Iesus puer*, translated into several languages, and has belonged to the Pontifical Academy of Arcades since 1718.
