A tourist amid the fragments of the Colossus of Constantine at the Palazzo dei Conservatori, Musei Capitolini, Rome, 1962. The original statue—which dates from between 313 and 324 CE and was some forty feet high—depicted the seated emperor and was installed at one end of the Basilica of Maxentius in Rome. Only the head and fragments of the arms and legs, all made of marble, have survived; scholars believe that the rest of the body was constructed of wood and mud brick. Apologies to eagle-eyed art historians: we have reversed the image so that Constantine’s astonishing face would not be concealed under our logo; the reversal has transformed the right hand of the emperor into his left.
