Jim, It's a long time ago since I talked to you at HallOfMaat. I'm so happy to finally talk to you again.

Here is a nice article on this topic of Shinar, for those wishing to learn more. Although the author finds a new location for Shinar that differs from Jim and I, it is a thorough and well constructed article that lays out the biblical passages in question. Note: The article references Jim as well.

Some of the highlights include:
"Accad of Genesis 10 is also spelled Akkad(e) and Agade in the literature (Arnold 2004, p. 23); and Archad in the Brenton and NETS LXX. We will use the Akkad spelling in this paper, because it appears to be currently the commonest one."
...
"Isaiah 10:9: “Is not Calno as Carchemish? Is not Hamath as Arpad? Is not Samaria as Damascus?”"
...
" Genesis 10:10 should read, “And the beginning of his kingdom was Babel, and Erech, and Accad, all of them in the land of Shinar.”
...
"It is this author’s suggestion that the Calneh of the Bible is Washshukanni (there are many spelling variations), capital of the powerful Hurrian kingdom of Mitanni (also called Hanigalbat), that rose to power some time around 1500 BC (Oates 1979, p. 207)"

As I've said.. I think Calneh is Karne, near Arados/Arpad (modern day Tartus). You can see it on the map near Hamath.
Archad instead of Akkad raises questions... Arqa was the Phoenecian Irqata. This Arqa kind of matches 2 names, Erech and Archad. Which to choose? It is located in this same block of cities, Zimyra, Karne, Byblos. If we identify Arqa as Archad, then what would Erech be?
