The frescoed gallery leads to the room of The Abduction of Proserpine. The mythological episode is portrayed at the centre of the ceiling: Proserpine is being abducted by Pluto, the god of the Netherworld, who tears her form her parents, Ceres and Jupiter, and takes her with him on his white horse.

The picture is inserted into an elaborate painted architectural structure with double banisters: on the lower series there are the allegoric figures of Poetry, Painting, Sculpture, and Music, to celebrate this place devoted to human arts. Poetry is carrying a book and some sheets bearing the date 1684, which corresponds to the year in which all the decorations commissioned by the Contarini family were completed, according to the critics. The same sheet also bears the initials MMP, recognised as belonging to Michele Primon, the painter. The initials should therefore mean "MICHELE PRIMON PINXIT" (painted by Michele Primon). Moreover, there are pairs of cherubs sticking out from the banisters and holding spectacular purple curtains, similar to those hanging in the Caryatid Room and adorning the doors in the Allegory Room. Big monochrome medallions brightened up by cheerful cherubs stand out from them. Each medallion is set inside a niche partially hidden by the curtains whose upper part is topped by a vase full of flowers and sided by two cherubs.

Fake niches with golden bronze statues are put at regular intervals along the walls; among them, there are a few Muses, Mercury with his traditional winged hat and his wand, Diana with her bow and a dog, and Minerva, the goddess who protects science and art, with her shield and helmet.
