Giulio was born into one of the leading families in Sinigaglia. The town of Sinigaglia, now known as Senigallia, is in central Italy and at the time of Giulio's birth was part of the Papal States. In fact the family went back very many generations in their association with Sinigaglia and one of the members of the family in the 12th century had been Lamberto Scannabecchi who became Pope Honorius II in 1124. Fagnano was brought up to follow the family tradition of high office in Sinigaglia. He was appointed gonfaloniere in 1723. Gonfaloniere literally means "standard bearer" and it was a title of high civic magistrates in the medieval Italian city-states such as Sinigaglia. Such offices were not easy in these times and Fagnano was subjected to many false charges made against him by envious citizens who were maliciously trying to damage his reputation. Fagnano had many children, one of whom was Giovanni Fagnano who followed in his father's footsteps becoming interested in mathematics. Giulio Fagnano was self educated in mathematics and treated the subject as a hobby. However, he achieved considerable international fame as a mathematician, and rightly so given the outstanding contributions which he made on a number of different topics.

Fagnano continued his father's work on the triangle and wrote an unpublished treatise on the topic. One theorem on the triangle which he discovered is worth quoting. He proved that given any triangle T, then the triangle whose vertices are the bases of the altitudes of T has these altitudes as the bisectors of its angles.

He improved Bombelli 's work on complex numbers. Considering triangles he looked at interesting problems such as: Given ABC find P minimising PA +PB +PC For a quadrilateral ABCD find P minimising AP+BP+CP+DP He also discovered that if X is the centre of gravity of the triangle ABC then XA +XB +XC = (AB +BC +CA )/3. In his study of the rectification of the lemniscate, Giulio Carlo Fagnano introduced ingenious analytic transformations that laid the foundation for the theory of elliptic integrals and his work was to lead to elliptic functions. He made many other major contributions. References (4 books/articles) References elsewhere in this archive: Giulio Fagnano was elected to the Royal Society of London in 1723.
