So this is further confirmation of a location site considered most likely for the last 35 years or so. Northern Germany, west of Hanover but still south of Bremen. the use of the word pass in all historical descriptions had always lead me to believe it was further south in areas of more topography.
I wish I had been able to travel Germany and see that varied land first hand, but alas, it is still on my list.
Yeah, the 19th c “memorial” to Herman/Arminius is way, way off.
