Illustrated on the back cover. Marcus Opelius Diadumenian was only nine years old when his father Macrinus was hailed Augustus. The Historia Augusta reports that he was an exceptionally beautiful boy, tall, dark-eyed and strikingly blonde, despite his father’s Moorish blood. Hopeful of establishing a new imperial house, Macrinus placed the portrait of Diadumenian on his coinage, naming him Antoninus Cæsar. After Macrinus’ defeat Diadumenian fled towards Parthia, only to be overtaken and put to death
