1. Almost all the characters from the Germanic Heroic Age, especially in the Nibelungenlied, have real world counterparts. For example, 5th century Hunnic King Attila becomes Atli in the saga/Nibelungenlied, Theoderic the Great becomes Dietrich in the Nibelungenlied/Poetic Edda, 4th century Gothic King Ermanaric becomes Jörmunrik in Beowulf/Ermenrich in the German cycles, Kriemhild/Gudrun seems to be inspired by the real world 5th century Ildico, Gunnar/Gunther by Burgundian king Gundahar, etc. Scholars long debated who could be the historical siegfried
2. Name dispute : arminius was not his real birth name. His fathers name was sigimer. Given the Proto-Germanic custom of giving children names containing at least one element found in the parent’s name, it is thus most probable that Arminius’ original name began with seg/sig. His brother in tacitus’ work germanis called Flavus. Flavus means blonde in latin. It was commn in roman culture to have name/nickname based on physical attributes. “armenium,” a vivid blue, ultramarine pigment made from a stone from Armenia. German who has blue eyes and his brother has blonde hair, not even surprising
3. Siegfried was suckled by a doe and died like a deer pursued by hunters: Arminius belonged to the tribe of the Cheruskans, a name derived from the Germanic word-stem herut “deer, hart.
4. Locarion of gnita heat. an Icelander named Nikulás Bergsson went on a pilgrimage that took him over 4,000 miles away from his home in northern Iceland to jerusalem in the Holy Land. We don’t know much about him, but it is clear that he was a lettered Benedictine monk. Around the year 1153, however, Nikulás left his home to venture out towards the Holy Land. By 1155, perhaps thanks in part to the prestige he gained through such a pilgrimage, he had returned to northern Iceland to become the abbot of the newly formed monastery at munkathvera, where he remained until his death in either 1159 or 1160. He was mentioning Kilianstädten where fafnir was slayed. tuetoburg battle didnt happend there but there was a roman forum waldgirmes which romans planned to be the first real settelement in the area, they were accumulating taxes they were gathering. after the battle, romans hastily abondoned east of the rhine and cheruski later sacked it. archeology says no traceable activity after 9ad and evidence of burning and looting . kilianstadten and waldgirmes less then 60km apart both east of Frankfurt.
5. Consistent themes in all versions.
The treasury : sacking of
Curse of the gold = germanicus revenge campaigns that depopulated and devastated everything between river wesser and rhein
Family betrayal = segestes betrayed arminius
Family murder: he was assasinated by his own tribe
There is only one historic figure whose story fits in all those
6.iceland connection : North germanic sagas are way more conservative and preserved than west germanic due to isolation. Nearly everything we know about pre christian bliefs of germanic peoples coing from iceland. iceland officially converted to christianity around 1000 AD but kept many old traditions for 200 years. private pagan worship in household was permitted as compromise for peacefull transition. İn the times of Nikulas, memory was very fresh. Prose Edda would be written down just 60 years after his death by Snorri Sturluson
