The Orthodox stayed true

[The Liturgist]

I'm not entirely sure what the thesis of this thread is, but I love a good map, and anything cartographic in general.
European tribes in the early middle ages is a fascinating thing to study.

You may find the history of the church in the British Isles quite interesting. Being at the edge of the former [Western] Roman Empire, the forms of Christianity which developed here are quite distinct from those of the European mainland.
Although not formally termed an 'Empire', the Celts of the British Isles maintained cultural and trade connections along the western seaboard. The map shows Hibernia (Ireland), Wales, Cornwall, and Brittany, but this extended further to Galicia.

On a slightly different topic, anyone else a devotee of the Paradox line of grand strategy (map staring) games? I have wasted/invested so many hours on Crusader Kings (1,2,3). There are some pretty neat mods for Crusader Kings 2 which extend the game's timeline back to the 6th century (albeit focusing on the British Isles and northern Gaul).

Paradox sounds interesting. I love that type of game although I prefer the sort where you build things, for example the 1990s Sim City games (versions 2000, 3000 and 4), Rollercoaster Tycoon, Transport Tycoon, etc.

I’m writing a novel set in a fictional North American city with a large mass transit system, and mapping the realistic development of that system from the 1860s until the present, including in the case of the 1991 map every individual route and service pattern, is thrilling, and has also produced a visually interesting map which you might like to see.
