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 old Bakhtiari is from the town of Saman, traditionally a 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.
