Antique Farahan rugs and carpets that were produced in the Arak region of west central Iran are remarkable for their ability to combine different qualities and sensibilities. The medallion design customary on so-called Sarouk-Farahans is classically Persian, as is all the minor detail. But the drawing is an interesting combination of suave curve-linearity and geometric styles.
Farahan rugs often come close to the angular drawing of Herizes and Serapis, but a much finer scale appropriate to designs of classical derivation. This delicacy of design relates closely to the weaving technique of Farahans, which is relatively tight and fine. The coloration of Farahan rugs and carpets tend to be rich yet soft, with emphasis on terracotta reds, delicate blues .
