Portrait of Constantine or of one of his sons

This head, slightly larger than life-size, is likely to represent either a juvinile portrait of Constantine, or a portrait of one of his sons. Dating to 1471, the Capitoline Museums are the world's oldest public museums. Their collection of classical sculpture is one of Italy's finest, including crowd-pleasers such as the iconic Lupa capitolina (Capitoline Wolf), a sculpture of Romulus and Remus under a wolf, and the Galata morente (Dying Gaul), a moving depiction of a dying Gaul warrior. There's also a formidable picture gallery with masterpieces by the likes of Titian, Tintoretto, Rubens and Caravaggio.
