The genesis of the work is linked to the controversy over the precedence that for forty years opposed the representatives of the Este house to the Medici, putting into play, beyond the apparent futility of the causes, reasons of substantial rank and prestige for both families, committed to consolidating the fortunes of their states. The two authors tell stories about Ferrara with particular regard for the members of the family of the Dukes of Este, pushed by them to magnify the glories of the city and, above all, of its rulers. On Gaspare Sardi (about 1480 – after 1559), in the Literary History of Italy, Giovanni da Pozzo, speaking of the language used, says that the Histories of Ferrara certainly do not benefit from a vernacular dedicated to annals aimed at mere support of a still formidable potentate.
