Note 41 — Chapter VI · THE CONVERSION OF THE SAXONS.
Reading edition
Berserker was a hero of Norse legend who fought without coat of mail and overcame all foes. His descendants, called Berserkers, went into battle under the inspiration of a fury, or demoniacal possession, in which condition gnawing the rim of their shields, howling like wild beasts, and foaming at the mouth, they were supposed to be invulnerable. This fury was the Berserk, or Berserker’s, rage.
