This fragment formed part of a larger relief. In keeping with Lombard workshop tradition, it may have been carved by a skilled assistant to Amadeo's design. The shield shows the French fleur-de-lis quartered with the serpent of the Visconti family, who ruled Milan during periods of French occupation.
