Federico da Montefeltro
With the decline of the political prestige of the Gabrielli family, Gubbio was thereafter incorporated into the territories of the House of Montefeltro. Federico da Montefeltro rebuilt the ancient Palazzo Ducale, incorporating in it a "studiolo" veneered with intarsia like his "studiolo" at Urbino. The maiolica industry at Gubbio reached its apogee in the first half of the 16th century, with metallic lustre glazes imitating gold and copper.
