This is not really an article, it only offers three maps with some spare additional information.
Three maps, made by GardenStone, all contain a little bit of historical Germanic information.
Map 1 offers an overview of names of Germanic deities in the region where now the Netherlands and Belgium are located. Most of the names are written at the places where the evidence for them were found, few are placed where they were worshiped. The names are passed down in different ways, for the big majoritiy of them it concerns inscriptions from the first few centuries CE.
The map shows the current geographic situation, which rather differs from ca. 2000 years ago.
Map 2 contains an overview of the assumed places where Germanic peoples in the first few centuries CE had their homelands at the territory where now the Netherlands and Belgium are located. Please note, that the locations of quite a few of them are equivocal. The map shows the current geographic situation, which rather differs from ca. 2000 years ago.
Map 3 contains about the same information as map 2, but now it shows the assumed geographic situation from ca. 2000 years ago.
