Historian born in Milan 1459, died perhaps in 1519. He served Lodovico il Moro, by whom he was appointed valet of Gian Galeazzo Sforza; after the fall of the Moro, he suffered pain and very serious damage. Noteworthy is his Historia patria (princeps 1503), the first history of Milan in the vernacular from its origins to 1499, precious (although often lacking in critical sense) starting from the age of the Communes, for the sources used, many of which are now lost.
