Interesting Fact - The Vikings
The vikings didn't wear horned helmets.
(They probably wore headgear in battle, but it was more likely made of leather, perhaps iron, and there were certainly no cow horns sticking out of each side.
We can blame Scandinavian artists from the 1800s, and Wagner for this historic innacuracy. Seemingly, Wagner's costume designer, Professor Carl Emil Doepler created horned helmets for the Viking characters in “Der Ring des Nibelungen” opera cycle in the 1870s.
Someone needs to tell Vicky the Viking!)
