General Notes

Gunther, also called GUNDICAR, GUNDICARIUS, GUNNAR, GUNDAHAR, or GUNTHARIUS, Burgundian king (died 437) who was the hero of medieval legends.
The historical Gunther led the Burgundians across the Rhine in the early 5th century, establishing a kingdom at Worms. He supported the imperial usurper Jovinus (411) and fell in battle against the Huns in 437.
Gunther (called Gunnar) figures in the Eddaic poem Atlakvida, in which he is slain by Atli (Attila) the Hun and avenged by his sister, Atli's wife. In the 11th-century Latin poem (Waltharius), he and his warriors try unsuccessfully to kill the hero (Walter of Aquitaine) and steal his treasure. The 12th-century German epic Nibelungenlied associates him with Siegfried, who helps Gunther to win Brunhild and in return marries Gunther's sister Kriemhild. When Siegfried is later killed on Gunther's order, Kriemhild revenges his death by having Gunther and his followers slain while visiting the court of her second husband, Etzel (Attila)
