There is some truth to this. Archeological finds have discovered helmets with horns and wings, but these have always been designated for the priests to wear during ceremonies. Vikings warriors did not wear them into battle. In fact, it is debatable whether Viking warriors wore helmets at all. So where did this myth come from? It most likely started with the ancient Roman and Greek writers like Plutarch, who vividly described the northern tribes as wearing all manner of strange things on their heads.
