Chimpman’s Known World 2300 BC, 8 miles per hex Working Coastlines v1
With apologies for the exceedingly long title… This was another major step forward for John’s 2300 BC Known World map. Through a series of exploratory and experimental maps, he had now built up a very detailed picture of the coasts and bathymetry of the area. With these now largely in place, it was time to begin developing the terrain. John explained in his post at The Piazza at the time:
Alright, I’ve got one more map. This one just shows the coastlines and ocean topography. I really only focused on the Brun coast, and the Thanegioth Archipelago/Island – The IOD is very rough at this point.
There’s a lot of nice detail in these coasts, and it’s clear that John put a lot of work into drawing this map. It comes as no surprise, then, that he used this as the basis of all of his future 2300 BC maps — the first of which he would release just a week after posting this one. Before that, he would revisit this map to begin adding some terrain.
