His first patron was the Marchese Guidubaldo del Monte of Pesaro, a man equally eminent in science, and influential through family connexions.
Thus he granted the Malatesta brothers the investiture of Rimini, Pesaro, Fano and Fossombrone, and they arranged a division of the state.
Guastafamiglia took Pesaro, which was held by his descendants down to the brothers Carlo and Galeazzo.
The latter won the title of " l'Inetto " (the Incapable) by the foolish sale of his rights over Pesaro to the Sforza in 1447.
Other cities where the ceramic industries keep their ground are Pesaro, Gubbio, Faenza (whose name long ago became the distinctive term for the finer kind of potters work in France, falence), Savona and Albissola, Turin, Mondovi, Cuneo, Castellamonte, Milan, Brescia, Sassuolo, Imola, Rimini, Perugia, Castelli, &c. In all these the older styles, by which these places became famous in the IthI8th centuries, have been revived.
