In the attack on Rome by the imperial forces of Charles V, Holy Roman Emperor under the command of Charles III, Duke of Bourbon and Constable of France, Cellini's bravery proved of signal service to the pontiff. According to Cellini's own accounts, he shot and injured Philibert of Châlon, prince of Orange (and, allegedly, shot and killed Charles III resulting in the Sack of Rome). His bravery led to a reconciliation with the Florentine magistrates, and he soon returned to his hometown of Florence. Here he devoted himself to crafting medals, the more famous of which are "Hercules and the Nemean Lion", in gold "repoussé" work, and "Atlas supporting the Sphere", in chased gold, the latter eventually falling into the possession of Francis I of France.
