Looking at Tim Kirk's Thurian Age Map I must say there aer a few things I disagree with. Howard said that Atlantis was a continent, and in the map it appears as a small island. Of course there really is no scale for the map so it might be that it just seems small. The biggest problem I have with it is the placement of the Pictish Isles. The Isles are the tops of mountains that will eventually be part of North America. The Picts and Native Americans both descend from these Islands in Howard's history. I just feel like the placement of the Isles is far too close to what would later become the Hyborian continent and even later Europe and Asia. As for Lemuria, I also think it is far too north on the map, not quite where I imagined it. Anyone else have any input on these subjects? Just curious. Great topic!
Hey RS! Here's what I had to say about Mr. Kirk's map three years ago (though be warned that my opinions have changed slightly since then)...
Lemme just say that I think Tim Kirk is probably the best map artist REH has had. His maps are clear, beautifully rendered and generally accurate. The have an "archaic" look that I find very evocative. Tim didn't have as much to work with on his Thurian Age map as say, his Hyborian or SK "Africa" maps. It would have taken a LOT more research (believe me) to have done the "Kull" map right. As we speak, I believe that Dale is working on a Thurian map. I think it's probable that I won't agree with THAT map either. I'll explicate those reasons to him when he posts his finished work. So, without diggin' out my notes, I'll touch on the major points against TK's map: west to east, north to south...
Kaa-u (Pictish Isles): also called the Sunset Isles. Tim chose to slap "Kaa-u" on the Pictish Isles. I can understand his reasoning, but for various reasons I disagree. The Isles are WAY too close to the Thurian mainland. The general opinion (and mine) is that the Pictish Isles are the tops of what will be the Rocky Mts. in the Hyborian Age (and ours). Moving east to Atlantis, we find, instead of a "small continent", a large island approx. the size of Great Britain or Madagascar. Atlantis is stated to be a navigational obstacle to the Picts and Lemurians. Therefore, I see Atlantis extending from the Azores, following the Mid-Atlantic Ridge almost to where Iceland would later rise. I envision Atlantis as being widest in the south, to accomodate the "savannah" and "jungle" of the Am-Ra tales (it also matches up with Plato). It then narrows in the middle and again widens out in the north. Sorta "spoon-shaped", you could say. The coordinates would be 35 N., 22-34 W. extending up to 67N., 15-25W.
Farsun: a major key and anchor for the whole map. It would appear that the Picts were settled in the mountains of the northern Farsunian/Valusian frontier. According to "The Hyborian Age", that's where we find them at the start of the HA. According to "The Lost Race", that's where we find the Picts (the Basques) from Neolithic times to the present day. Basically, Farsun=Zingara=Iberian Peninsula. I have Farsun sticking out to 12 degrees W. to accommodate the extra land up north while still being "westernmost".
Commoria and Thule: Commoria isn't even mentioned in the Kull tales. Not sure about Thule. Since "Thule" was originally applied to what geographers thought was the northernmost land, I'm placing it in the vicinity of the most northerly British Isles, about 60N., 8W. Commoria I see tucked into the southeast flank of Thule with no common border (in the time of Kull) touching on Valusia. Ever noticed the similarity between "Commoria" and "Cimmeria"? I think this is the area conquered by the northern Atlanteans.
Valusia: I place its western (coastal) boundary at about 6 degrees W., tucked in between the Farsunian and Thulean peninsulas, extending from 43-54 degrees N. Valusia (aka, "the City of Wonders"), the capital of the empire of Valusia, is positioned about where the Italian city of Bergamo is now situated. The Zalgara Mts. run north-south roughly along the 15 degrees E. meridian.
Kamelia and Verulia: I envision Kamelia occupying (roughly) a region including Holland, s. Denmark and n. Germany. I see Verulia situated s-e of Kamelia in the region roughly corresponding with Germany south of Berlin,plus Switzerland and w. Austria. This is because Dalgar, in "Swords of the Purple Kingdom", thought he could reach the Verulian border from the Valusian capitol IN ONE NIGHT!
Zarfhaana: I see this ancient kingdom encompassing Poland (s. of Warsaw), Slovakia, Hungary and Serbia (very roughly). There's a gulf n. of Warsaw "swarming with pirates and sea-rovers". The Camoonian Desert is now covered by the nations of Croatia and Bosnia. The Zhemri Mts.,"in the southeast", which "I" take to mean "the southeast of the Seven Empires", are basically the Balkans today. The "Zarfhaana'an Mts.", where lies Talunia, run roughly north-south on the 25 degrees E. meridian.
Grondar: lies betwixt the 25 E. and 35 E. meridians. It's n. border is where the Stagus empties into the "Zarfhaana'an Gulf". It's s. border lies somewhere about the 42-43 N. parallel.
Stagus R. and the World's End: I believe REH intended the Stagus to become the Styx after the Cataclysm. Instead of running due north, the Cataclysm turned the course of the Stagus due east at the 35 N. parallel. I've had the Stagus "meander" 5 degrees east to give Grondar a little more room. The World's End? It stretches east for a LOOONNG ways.
Thurania: covers an area stretching roughly from Sardinia to Istanbul, south to Crete and west to Tunis. It shares a western border with Farsun, its ancient enemy. VERULIA is never described as being south of Valusia.
"lesser principalities": stretch in an arc 100-200 miles deep, starting from Grondar's s-e border all the way to Farsun.
The Lost Lands: Why are they called "the LOST Lands"? I think there's a very interesting answer for that, but I shan't go into it now. I think they occupy a major portion of what we now call the Middle East.
That's enough for now. I'll just note that Tim didn't make the Thurian (Eurasian/African) continent anywhere near big enough, since we know that the eastern seaboard was pretty close to what it is today. Of course, if I had to cram all that on two paperback-sized pages, I probably would've compressed some things myself. 
That, plus the new (and fairly accurate, IMO) map of the Seven Empires that I worked up for my presentation on the Thurian Age down at Howard Days '07 and plenty of other stuff about Thurian Age maps is on THIS thread:
