Oil on canvas. Lombard school of the 17th century. On the first canvas and mounted on the original frame. Set in a prison, the scene shows Saint Ambrose the bishop directing the person on his right, a soldier with a cross around his neck, towards the sky. He can be identified as Saint Victor, a Roman soldier originally from Mauritania, who served in Milan at the time of Maximian and was martyred for his Christian faith. It was the bishop of Milan who recounted the life and martyrdom of the saint in one of his writings and who spread his cult. On the left, another probable martyr of the faith, who witnesses the proclamation of the beatitude of his cellmate; around, numerous other figures of condemned men. The octagonal painting probably belongs to a series dedicated to the cult of the Holy Bishop of Milan. The canvas requires restoration and cleaning, presenting several stains and cuts (a tear in the centre, other smaller ones on the sides).
