Of the Austrian Netherlands, Count Joseph de Ferrari published a chorographic map on the same scale as Cassini's Carte de la France (1777).
The Piazza Ferrari, a large irregular space, is the chief focus of traffic and the centre of the Genoese tramway system; it is embellished with a fine equestrian statue of Garibaldi, unveiled in 1893, which stands in front of the Teatro Carlo Felice.
He conceived methods for the general resolution of equations of the second, third and fourth degrees different from those of Ferro and Ferrari, with which, however, it is difficult to believe him to have been unacquainted.
Subsequently, towards the close of the 15th century, the refined court of Lodovico Sforza attracted such celebrated men as Bramante, the architect, Gauffino Franchino, the founder of one of the earliest musical academies, and Leonardo da Vinci, from whose school came Luini, Boltraffio, Gaudenzio Ferrari, Marco d'Oggiono, &c. Later, Pellegrino Tibaldi and Galeazzo Alessi of Genoa (the former a man of very wide activity) were the chief architects, and Leone Leoni of Arezzo the chief sculptor.
About Cardinal Ferrari's death there is more doubt; he probably died of fever, but the pope immediately confiscated his goods.
