User blog comment:Theory of everything/Grimm Speculations Part Three: The Key/@comment-1114229-20120608221537

I finally got around to uploading a couple of images in png format. File:Atlas.png shows some interesting things: 1) An area labeled in part as "BEL", 2) An area labeled in part as "FR", and the latitude 52 degrees.

Of course, we don't know if Nick has the right map, but when he places the key map over the atlas page, the scales on the left line up. The key map is cleverly crafted to not show any coast line.

Fifty-two degree north crosses onto the European continent just south of the Hague, Netherlands, which is north of BELgium and south of an area once (and possibly still) known as FRisia.

Mannheim is about 150 miles from the coast.
