The author addresses the Dante theme of the end of Ugolino della Gherardesca and his boys imprisoned in the tower of Pisa. He titled small and large formats, grouping them in two narrative variants: one in which the protagonist shows to welcome the disaster with heroic resignation, and one literally illustrative of the verse "both hands for pain bites me". The one exhibited in Cremona is one of the versions of the first iconographic group, next to the canvas that Diotti painted for Count Paolo Tosio (now in the Civic Museums of Brescia) and which he exhibited at the Brera Academy, enjoying widespread critical appreciation. He departs from it for a simpler study of light and a greater pathetic charge of all the actors. In particular for the head of the protagonist, with a long beard with a shocked expression.
