There was also a lot of mythology of that sort being created or imagined by academicians and projected on history around the turn and early half of the twentieth century. It was later overturned, but to put it in vaguely Hegelian terms, it was a bit like a spirit trying to come into being and took on a life of it's own... I'm not an expert in anything, so...

I guess he had a fondness for Anglo-Saxon and Teutonic languages going by the letters in the book; Beowulf, for example. His dislike of the Gaelic language was a little bit of a surprise to me, though.
