"Much of the information on 14th century northern Italy comes from Mussato's histories such as the "Historia Augusta Henrici VII Caesaris" (History of Henry VII) and the "De Gestis Italicorum Post Henricum VII Caesarem" (Concerning the Deeds of the Italians after Emperor Henry VII).The former is an account of Emperor Henry VII's expedition to Italy from 1310–1313 and the latter is an account of Italian politics "from August 1313 to at least July 1321".
