Antique Persian carpets from the Ferahan (also spelled Farahan or Feraghan) plain in central Iran, known for all-over Herati patterns and subtle color palettes. These 19th-century rugs typically feature a diamond lattice of small floral motifs, often in navy blue, rust red and ivory, and are prized for their fine weave and balanced, restrained compositions. In today's trade the name is also used for newly made Pakistani workshop rugs of the Peshawar (Chobi) type, woven from hand-spun wool and vegetable dyes in subdued colors and mostly Persian-inspired all-over designs, and sometimes for Sarouk rugs from the same region; such rugs are not antique Ferahan carpets.
A classic Persian design built on a diamond repeated across the field, with a small flower or leaves inside each diamond and curved leaves at its sides; the leaves are read as stylized fish, said to circle a lotus. The name comes from Herat, the city in Afghanistan where the design is said to originate; it is also called the fish design, and Mahi means “fish” in Persian. It is one of the three main design families, woven as an allover pattern or around a central medallion with diamonds inside and outside it, and it sometimes appears as a thin border. It is common in Tabriz, Sarouk, Mashhad, Moud, Bijar, Hamadan, Abadeh, Zanjan, Kerman and Kashan rugs.
