Exterior Decorations
On all the windows of the first floor on the facade overlooking the garden, as well as on some ground-floor windows and the three central ones on the facade towards the courtyard we find bas-relief ornamentation conceived – in both content and form – by Giuseppe Parini.
One of the first exponents of Neo-classicism, this poet was invited by the patron to create mythology-inspired decorations that would emphasize the Villa’s prestige, nobility, generosity, and hospitality (see the list of reliefs below).
In order to transform these contents into images, in all likelihood Parini turned to the painter Giuliano Traballesi to coordinate his team of sculptors who were already working on the prestigious facade of the Duomo: Donato Carabelli, Cesare Ribossi, Andrea da Casareggio, Grazioso Rusca, Carlo Pozzi, and Angelo Pizzi.
In addition to the reliefs, alternated with Ionic columns on both facades, the cycle possesses thirty statues of classical deities on the balustrades of the upper section in correspondence to the columns themselves. Cronus, Cybele, Vesta, and Pluto can be found at the entrance to the ceremonial courtyard. Instead, on the side of the garden we find, from center to left: Juno, Apollo, Neptune, Minerva, Bacchus, Ganymede, Iris, Pomona, Pan, Naiade, Silenus, Maenads, and Hypnos and, from center to right: Jupiter, Venus, Cupid, Amphitrite, Mars, Ceres, Mercury, Hebe, Flora, Zephyr, Silvanus, Amore, and Cephalus. The balustrade runs between both large gables to the sides, which in turn are decorated with motifs of the Chariot of Day and Chariot of Night.
