Since the 18th Century, Fereghan rugs from between Arak and Kashan have ranked among the best fine rugs in Persia. The various mosaic designs of these rugs, of which there are around 20 variants compose of, the famous ‘Herati’ pattern, central motif designs, tree of life prayer designs and diamonds filled with rosettes. The border designs are ornamented with angular palmettes, leaves, rosettes. Colours tend to be light blue, purple, or rare natural white.
Fereghan carpets are unlike their neighbours Sarouk which are more formal often using an elaborate central medallion. Fereghan weavers preferred floral motifs of shrubs and vines using more green dyes and hints of yellow. Fereghan or Ferahan rugs were woven in the Arak district which was once the capital of Persia. They wove a variety of designs with Sarouk-Fereghan rugs more classical in their structure and rugs from Malayer and Fereghan using palmettes, shrubs, geometric motifs.
