Azerbaijan, NW Iran
This is a densely-knotted pure tribal expression. To see these high plains in winter is to understand. The people are the great Qizil Bash Turkic Persian Empire builders. They are partially nomadic to this day, with the boys herding the sheep to available grass throughout the seasons while the rest of the family remain in thick-walled villages.
The commercial dealers lump these interesting rugs with all the rest that end up in the Bazaars of Ardebil. I call this rug Meshkin but her grandmother’s rug would be Shahsevan the old tribal name which has fallen out of use these days.
