The Loggia owes its name to the painter Girolamo Romanino from Brescia who between 1531 and 1532 frescoed this important area that links the buildings that make up the Magno Palazzo, and thus creating one of his masterpieces.
In the middle of the ceiling is a painting depicting Phaethon in the Sun chariot pulled by fiery steeds in a dizzying race across the sky. On the sides are allegories to the Seasons, the Sun and the Moon; in the pendentives, great male nudes emerge from trompe-l’oeil shelves with life-like effect.
The lunettes depict biblical, profane, mythological, and Roman history scenes. Beginning on the wall by the stairs there is: Judith and Holophernes; a flute quartet; Virginio killing his daughter; Lucretia’s suicide; the Graces; Cleopatra’s death; a concert; Samson and Delilah; a courting scene; Venus and Cupid.
