So, in linguistics we have the family tree of languages going back to the Proto-Indo-European. Is there any similar scholarship suggesting Judaism back before the Babylon days was related to any other religions? Is the idea of a prehistoric bridge between Abrahamic and Dharmic faiths (for instance) utterly ridiculous or are there linguistic and cultural links that hint that might be the case?

I had a question about Benjamin of Tudela's itinerary: who was his intended audience? How common were such journeys among Jews around the same time? Why does he spend so much time describing the Exilararch and the towns of nowadays Iraq and Iran, compared to what I assumed to be his destination, Jerusalem? Who could and how could they afford such a journey? And most important, are there versions of his itinerary transliterated into modern Hebrew? I only found manuscripts in scripts I can barely read.

How would you say "the wife of Dunash ben Labrat" in Hebrew (including transliterated in the Roman alphabet)?
