Dietrich Of Bern
From BiblePortal Wikipedia
Dietrich Of Bern [1]
A favourite hero of German legend, who in the "Nibelungen" avenges the death of Siegfried, and in the "Heldenbuch" figures as a knight-errant of invulnerable prowess, from whose challenge even Siegfried shrinks, hiding himself behind Chriemhilda's veil; has been identified with Theodoric the Great, king of the Ostrogoths.
