Giordano Bruno
In 1861 he moved from Spoleto to Maddaloni, near Naples, where he published: "Il Panteismo di Giordano Bruno" ("The Pantheism of Giordano Bruno"). Fiorentino used to compare himself to Giordano Bruno for their similar character and to Vincenzo Gioberti for their similar political views. Thanks to this book he became a teacher at the University of Bologna in 1862. He stayed there for nine years, and here he wrote many books, like "Pietro Pomponazzi "or "Scritti varii".
