Emperor Nero played the fiddle while he watched Rome burn.
According to Tacitus, a historian at the time, Nero was not actually in Rome when the fire broke out, he was in his villa in Antium (about 30 miles away).
When Nero heard about the fire he rushed back to Rome to organize relief efforts.
Also, it would have been impossible for Nero to have played the fiddle; it did not exist at the time.

The costume designer, Carl Emil Doepler, created horned helmets for the Viking characters for use in the production.
