Sorry but I think there should be alittle correction in the map names (in the first post)
The name of this map should not be Armenia. It should be Georgia. it includes the whole Georgia(Kartli and Lazica) and a small part of Armenia. So I think the name should be changed 

Here is a map to compare the territories. it is not the map for the exact date but from this map you can see what territory it is.
PS. Egris is Lazica. We Georgians called it Egris, and Bizantines called it Lazica 
Really nice maps
