> the real showstopper is an amulet called a bracteate with two stylized designs: a man in profile, his long hair pulled back in a braid, and a horse in full gallop. An expert in ancient runes says she was awestruck when she finally made out the inscription on top: “He is Odin’s man.”
> These embossed runes are the oldest known written mention of Odin, the Norse god of war and ruler of Valhalla. Ginnerup’s bracteate, which archaeologists describe as the most significant Danish find in centuries, extended the worship of Odin back 150 years
I don't think this is right. The first mention of Odin by a Germanic source could date to 500 AD. But the Romans wrote about the Germanic gods several centuries prior to that. They used the equivalence we still use today, calling Odin "Mercury". But what they say about the Germanic gods is compatible with what we know from Germanic sources; there's no reason to believe there was a change in the gods.
I note that the image on the bracteate features a pretty prominent swastika. Maybe Hitler was accidentally on to something after all.
