Ferreto wrote in
Latin. His best known work is his
Historia rerum in Italia gestarum ('history of Italian deeds'), a history of northern Italy—both
Venetian and
Imperial—from 1250 to 1318. The central episode of the
Historia is the
Italian expedition of
Henry VII of Germany (begun 1310), his coronation as
Holy Roman Emperor (1312) and his premature death (1314). The conflict between the
Staufers and the
Angevins following the death of the Emperor
Frederick II (1250) provides the background. Ample space is also devoted to the rule of the
Habsburgs from 1291 to 1308. Ferreto was an eyewitness to much of the later history in his
Historia. He also makes use of the contemporary
Historia Augusta of Mussato, although he has a diametrically opposed attitude to
Cangrande I della Scala for his liberation of Vicenza from Paduan control, which Mussato laments and he praises. He shares Mussato's view that history is a guide to action in the present. Although he endeavours to be objective, his
partisanship of the Empire shows through. Ferreto probably began work on the
Historia around 1330 and was still working on it at his death. It is conserved in a single manuscript, now in Vicenza,
Biblioteca Civica Bertoliana, MS 314 (formerly
shelfmarked G.7.9.17 and Gonz.21.10.12). Ferreto also wrote poetry. His
priapic verses survive only in fragments. He wrote a poem in 110 lines on the death of Dante Alighieri in 1321, although it appears unfinished. It was written between Cangrande's takeover of Padua in September 1328 and his death in July 1329. The original poem was in four books, but the surviving version has a fifth book in
metrical prose that is not by Ferreto. All of Ferreto's works have been published by . Ferreto was an early humanist. His achievements in that regard exceed those of his teacher, Campesani. He shares "with Mussato the honour of inaugurating a novel historical technique, which marks the beginning of humanist historiography." In his works, "the rôle of the individual in the shaping of events" is more pronounced than in other medieval works. ==Notes==
