The Lattanzio Gambara fresco
In the upper part, Lattanzio Gambara has painted the last stage of Christ’s life cycle – the Ascension – conceptually linked to Correggio’s Assumption of Mary in the cupola. Christ is depicted at the top of the wall, with the apostles situated at the height of the matronea, facing the sky, from which two large angels in white robes are descending. At the bottom, either side of the door are two large monochrome figures: a king and Samson, who holds in his hand the donkey’s jawbone with which he killed a thousand Philistines. At their feet, two lions replicate the Christological symbolism of the Lion of Judah triumphing over Satan and the world. According to tradition, the figure overlooking the inside of the Cathedral, on the left-hand side of door, is Lattanzio Gambara himself. He is mirrored on the right by a similar figure, said to be Bernardino Gatti, known as the Sojaro. At the time, he was working on the Sanctuary of Santa Maria della Steccata, and probably responsible for bringing Gambara to work on the Cathedral.

The stained-glass window
The large stained-glass window dates back to 1954 The standard in the middle is the coat of arms of the Mount of Piety and depicts a pietà (an image of Christ deposed from the Cross). Saint Bernardo degli Uberti, patron of the diocese is depicted on the left and Saint Hilary of Poitiers, patron of the medieval town and now the city, is on the right.
