By using French and Italian archive sources we describe Cauchy's life and work in Gorizia for the
first time in historiography. We claimed that Cauchy's close connections with Jesuits did not affect
just his political activities, but also a great deal of his scientific work. The scarce preserved Cauchy's
manuscripts help us to throw some light on the Cauchy's role at the exiled Bourbon court in Gorizia.
We find the main Cauchy's scientific collaborators in Prague, Vienna, Graz, Ljubljana, and Gorica.
In that way we present the most probable scenario of Cauchy-Mocnik collaboration on Močnik's
popularization of Cauchy's theory ofequitation and on Močnik's Ph.D. dissertation in Graz. With that
work Cauchy considerably influenced the development of Slovene mathematics.
