Chimpman’s Mogreth 2300 BC, 8 miles per hex City Comparison
This map provided a snapshot into the city placement thinking of John Calvin and Geoff Gander as they designed Mogreth, in late August 2009. Geoff had just posted an altered map of Ylaruam showing the positions of Mogreth’s chief settlements. John replied on The Piazza:
Here is an overlay of the city placement on the 24mph map with the city placements at 8mph specified in your above map.
Isshum, Theliir, and Teshos are spot on. It looks like Ithkesh and Ussur may be off by a hex (either on the original map or the new map). Ssugath I’ve placed directly over the modern position of Tameronikas. That one is way off from your original positioning in the 24mph map.
Frankly I like the idea that Ssugath = Tameronikas, but we’ll have to make some changes to the map if we want it to be so. I suppose that the swamp could be extended all the way to the hills.
Most of these placements stuck — all but Theliir in the south, which they moved another 24 mile hex south.
The slight misalignment here was likely due to the inherent misalignment between 8 and 24 mile per hex maps of this region of the Known World that originated in GAZ1 and GAZ2.
