Heads Will Roll

Roman portrait statues were often built with detachable heads. When a new emperor took power, sculptors didn't carve entirely new statues — they simply removed the old head and attached a new one to the existing body. The toga-clad torso, the military breastplate, the heroic nude body stayed the same. Only the face changed.

This wasn't laziness. It was political efficiency. The Roman Empire covered millions of square miles, and every town needed statues of the current ruler in public spaces. Carving new full-body statues for every emperor across the entire empire would have been impossibly slow and expensive.
