So far only a few rugs have been identified:
"Charles Robertson 2 detail" as a Karachov Kasak.
The last picture on Robertson’s page as Chajli.
Gérôme’s "Markos Botsaris" is a "Talish inspired" rug and the "Uzbeq embroidery"
is better defined as a Samarkand suzani.
Well…What about the others?
I am particularly curious about this one:
It’s a Caucasian, yes, but does it belong to a recognizable type?
And the first on the left from Gérôme’s Prayer in the House of an Arnaut Chief
What is it? Caucasian, Kurdish, East-Anatolian?
Dear folks -
No one is responding to Filiberto's challenge here, so I'll say what seems fairly obvious that the medallion in the first rug above is quite similar to some (usually the center on rather than the end ones) that appear on the Caucasian Kazaks, called "Luri-Pamak."
Here is an example:
There is also what Bennett calls a related group of "three medallion" Kazks that have similar medallions.
The border on the rug Filiberto refers to in the first painting is not reproduced in any Caucasian rug image I can find quickly. But there is a somewhat different version (diamonds in between rather than within devices containing the hooked elements) in some "pinwheel" Kazaks.
Best I can do on this one.

I think we’ll have to stay with the triple-medallion Kazak definition.
The main border looks like a plausible variation of the "kufik" motif.
It has to be seen who made the variation: Robertson or the weaver?
