Your Bakhtiari is a great example of the classic central medallion design which is considered to be a metaphor for a prosaic reality in the corners, layering to a deeper consciousness in the center. This fine Bakhtiari is from the town of Saman. Saman traditionally was the source of the finest Bakhtiari rugs and the area of the nobility. These days the appellation Saman simply means a finely knotted rug from anywhere in the Chahar Mahal. Saman can be found on google maps.
