The ceramics produced during the era of the Della Rovere family came from the ancient Casteldurante, which is now Urbania. Contacting the extremely skilful majolica craftsmen of Urbania to execute these splendid majolica was an obvious choice. Basing his work on some photos proposed by Andrea Ippoliti, the ceramist Silvio Biagini created majolica containing the allegories present on the ceiling of the Ducal Palace.
