SCOTLAND: The Roman builders of the Antonine Wall used vibrantly painted sculptures as a propaganda tool to convey Rome’s superiority over native Scottish tribes. When the wall was built in the mid-2nd century A.D., sculpted blocks depicting Rome’s military exploits were periodically embedded into it at strategic locations. X-ray and laser technology has now shown for the first time that they were originally finished with red and yellow paint, which would have enhanced their visual impact.
