The Pasquino Group is a group of marble sculptures that copy a Hellenistic bronze original, dating to ca. 200–150 BCE. At least fifteen Roman marble copies of this sculpture are known. Many of these marble copies have complex artistic and social histories that illustrate the degree to which improvisatory "restorations" were made to fragments of ancient Roman sculpture during the 16th and 17th centuries, in which contemporary Italian sculptors made original and often arbitrary and destructive additions in an effort to replace lost fragments of the ancient sculptures.
