I haven't read through this thread yet (I will soon) but I recently came across a Germanic link to the Y head that Q has posted about a few times. I think it comes from a Germanic rune the nazi's used called the life rune. It's not exactly a Y, its inside of the peace symbol right side up, however the german word for it comes from the common germanic word for elk, which would explain the Rothschild elk head costume. I think we should dig into this.

Also I don't know if anyone has dug into this but the germanic tribes of Europe are more important than the vikings. They conquered Rome and much of Europe later on as the franks (merovingians and carolingians), eventually becoming the holy roman empire.
