Giovanni Sabadino degli Arienti (Bologna 1445 – Bologna 1510) was an Italian humanist, author and poet. He worked as a secretary for Count Andrea Bentivoglio. His most famous work Novelle Porretane (1483) is a collection of sixty-one tales in imitation of Boccacio's Decameron. In De Triumphis Religionis, a treatise on the virtues of a prince, he described the court of Ercole d'Este as an exemplar of the virtue of magnificence. Long relegated to obscurity by critics of his "arid" style, Arienti has enjoyed more appreciation recently for his attempt to create a Bolognese literary vernacular.
