Hello /asatru/, I was making research about my ancestors(Türks) beliefs and traditions, I've found a source about both our and your people. I've found this book neutral enough, and I wanted to share it since you guys intrested in with this kind of stuff.
Also by saying 'rus' in that script, most likely he refers kievan rus who are scandinavian.

He thought scandinavians were dirty but very handsome, if I'm not wrong it's mentioned in one of these sources.
Sorry for if it's posted before and bad english
