The Piano Nobile
The staircase that leads to the upper floors (on the left-hand side there is an access to the cowsheds), is a typical example of Roman Renaissance: between two walls, the ceiling with barrel vaults and a window at the back. After the first flight of stairs, on the right-hand side, there is a niche which hosts a male bust, on a fluted base, resting on a Ionic capital. In the middle of the vault on the first landing there is the Cardinal’s coat of arms.
After the second flight of stairs on the landing of the first floor we can see an arch fringed with Doric pilaster strips resting of socles adorned with the Cardinal’s coat of arms. We find here the motif of round plaques in polychrome marble, which we have seen used in the courtyard.
Inside, in the hall, the ceiling is adorned by coffers which present four figures of Sybilla. The moldings of the coffers present fine friezes with winged figures facing one another, the Chalice with host and other figures.
On the left-hand side, there is Sala Serpieri, superbly preserved, with a marvelous ceiling, floor in terracotta tiles and frescoed walls, in which we find a magnificent fireplace built in cipolin and surmounted by an allegoric scene. Among the treasures and antiquities of the palace, most of which lost, there is a fresco, considered excellent by Vasari, by Raffaellino del Colle, on cardboard by Giulio Romano, which represents the Holy Virgin with sleeping Christ Child and a marble memorial stone from the empire age (I century A.C.), surmounted by a sundial, which was used as a crop calendar (called “menologium rusticum Vallense”). This “menologium” (so named by Mommsen) was created at the same time as the so-called Colotianum, now at the National Museum of Naples.
