Hi Pierre,
Many thanks for another interesting research on the subject!
Of course, as the official Caucaso-maniac on board, I am at once interested in the “Scheunemann rugs”. I agree, the one in FIG 147 has a familiar Caucasian flavour.
I can even (je-sais-quoi!) pin down one of the familiarities: the minor white-ground border with stylized “S”: I have a rather uncommon Caucasian flat-weave bag (Tabasaran according to Gamzatov or Lesghi according to Nooter), wool on cotton ground, with a very similar border.
Nooter’s “Flat Woven Rugs and Textiles from the Caucasus” shows three others examples in plates 135, 187 and 188. The last two have small rhombuses between the “S” instead of rectangles as in the border in FIG 147. Here is the scan of plate #188:
A quick and by no means exhaustive search among Anatolian and Turkmen rugs (didn’t look into the Persian, though) offered no results. Which doesn’t mean a similar border could not emerge if one looks harder around in the wider Rugdom production, of course. Nevertheless it’s still a tiny connection to Caucasus, don’t you think?
Regards,
Filiberto
