Persian Heriz rugs come from Heris and its wider weaving district in East Azerbaijan, northwestern Iran. They are best known for powerful geometry, especially large medallion-and-corner compositions, but the tradition is more varied than the familiar red field and angular central medallion suggest.
This guide brings together museum records, Encyclopaedia Iranica, and Persian academic research on Heriz design. It explains the region, history, structure, Cheshni pattern system, named designs, colors, market terminology, identification, value, and care. Where evidence applies only to one rug or a specialized group, the distinction is made clear.

What is a Heriz rug?
A Heriz rug is a pile carpet attributed to Heris and the surrounding weaving area. Encyclopaedia Iranica's survey of Azerbaijan lists Heris among the districts whose carpets became well known in Western markets. In English records, the place name may appear as Heriz, Heris, or less commonly Hariz.
Heriz should not be confused with Herati. Heriz is a place and regional carpet attribution. Herati is the name of a repeating motif used in many weaving areas. A rug can have a Herati pattern without being a Heriz rug.
The classic Heriz look combines a strong central organization with stepped or serrated drawing. Flowers, palmettes, leaves, and vines may lie beneath that geometry. The design is often bold enough to read from across a room, while closer inspection reveals small variations introduced during weaving.
Where are Heriz rugs from?
Heris is northeast of Tabriz in East Azerbaijan. Persian field research describes the town as the principal name within a broader network of nearby villages and production centers. Trade labels such as Bakhshayesh, Goravan, Mehraban, Karaja or Qarajeh, and Sharabian are connected with this wider northwest Persian context, but dealers have not always used the names consistently.
A 2014 field-based study in Goljaam notes that the Heriz area maintained recognizable principles in design, motif, color, and weaving while individual rugs and village practices still varied. This is why regional attribution should combine structure, design, age, provenance, and comparison with documented examples, rather than rely on a single medallion or commercial label.
Heriz rug history and the Tabriz connection
Heriz weaving has a local rural identity, but it did not develop in isolation. Tabriz was a major commercial and design center. Merchants and producers helped transmit commissions and patterns between the city and surrounding weaving districts. Heriz weavers then interpreted those designs through local materials, working methods, and visual preferences.
Iranica's study of Qajar-period carpets records a major expansion in Persian carpet production and export from the 1870s to World War I. Foreign demand affected sizes, palettes, and designs, while regional structures and design languages persisted. This commercial history helps explain both the international fame of Heriz carpets and the exchange of ideas between Tabriz and village workshops.
The Museum of Fine Arts, Houston identifies one Heriz carpet as made in Iran around 1870. It is a useful dated object for understanding nineteenth-century production. It does not prove the age or construction of another rug simply because that rug looks similar.
How are Persian Heriz rugs constructed?
A knotted pile carpet is built from lengthwise warps, crosswise wefts, and rows of knots whose cut ends form the pile. Fibre, yarn twist, knot type, weft arrangement and tension, warp depression, pile height, finishing, and repairs all affect the finished rug.
The Houston museum's circa 1870 example has wool pile on cotton warp and weft, symmetrical knotting, and a recorded density of 121 knots per square inch. Those details document that individual carpet, not a universal Heriz specification. Iranica's technical survey also explains that symmetrical and asymmetrical knots occur across the Near and Middle East. The older terms "Turkish knot" and "Persian knot" are therefore poor stand-alone tests of geography.
Iranica's review of carpet materials reports that Heris-area weavers once used fine, lustrous wool supplied by Shahsevan groups and later also obtained wool from Ardabil. Supply and materials changed over time. A seller should describe the actual pile and foundation rather than repeat one story for every Heriz rug.
Knot count is only one characteristic. A lower knot density can still support clear, confident drawing and durable construction. A high knot count does not by itself prove age, origin, quality, or value.
Cheshni: the Heriz handkerchief pattern system
The old claim that every Heriz rug was woven entirely from memory is too simple. Weavers could draw on memorized design knowledge, existing rugs, woven samples, graph-paper cartoons, and small cloth patterns known locally as Cheshni, often translated as "handkerchief patterns."
Abdollah Mirzaei's Goljaam study of Cheshni patterns describes a small piece of plain white cloth, commonly about 20 by 30 to 30 by 40 centimeters, carrying a painted design for part of a carpet. A Cheshni might show a quarter of a medallion-and-corner composition. A border could be supplied separately or woven from established knowledge.
The small cloth did not dictate every knot. It provided a framework that the weaver enlarged, simplified, completed, and varied. Curving lines drawn on cloth could become stepped or semi-geometric when translated into the carpet grid. Weavers could add or omit secondary motifs, adjust the spacing, and adapt the same design to different rug sizes.
This process helps explain why related Heriz rugs share a recognizable structure without becoming exact copies. Mirzaei argues that standardized printed and digital cartoons made weaving easier but reduced some of the variety and local design vocabulary encouraged by Cheshni use. The point is not that one method is automatically better. It is that Heriz angularity reflects a design process and regional aesthetic, not a lack of technical ability.
How to read a classic Heriz design
Mohammadi and Vandshoari's field study of contemporary Heriz design found recurring structural principles across six commonly woven design families. The rugs were not identical, but their organization could be compared through the size and form of the medallion, corners, connecting elements, borders, and repeated motifs.
In a classic lachak-toranj, or corner-and-medallion composition, three main zones organize the field:
- Toranj, the central medallion: often a large diamond, square, or layered geometric form that anchors the design.
- Lachak, the corners: four corner sections that answer the central medallion and help hold the composition together.
- The field between them: filled with angular leaves, flowers, palmettes, rosettes, vines, and smaller connecting devices.
A main border usually surrounds this field with narrower guard borders. Stepped outlines make the transition between zones feel forceful rather than delicate, yet the internal motifs may still derive from curving vegetal forms.
Named Heriz design families
Local and commercial names often preserve associations with designers, merchants, or recognized arrangements. The Persian field study discusses designs including Tajeri, Samad Khani, Sabouri, Esmail Beig, and an all-over Afshan format. These names describe design families, not a mechanical checklist for authenticating a rug.
Samad Khani designs are especially useful for seeing how a rounded or layered medallion can be translated into semi-geometric drawing. Details and proportions still vary from one rug to another.
Samovar and Baligh-Shamama borders
The samovar border uses a repeated vessel-like unit in the main border. It is sometimes compared with the broad trade label "turtle border," but the local samovar name is more specific to the form discussed in Heriz design studies.
In the Baligh-Shamama border name, baligh means fish in Azerbaijani, while the study describes shamama as a type of round flower. The border combines fish-like or leaf-like elements with round floral units. These names are valuable parts of local design vocabulary, but they should not be turned into fixed symbolic claims without evidence.
Rare pictorial and all-silk Heriz carpets
The familiar wool medallion carpet is not the whole story. A 2025 study in the University of Tehran's Journal of Fine Arts: Visual Arts examined a specialized group of all-silk pictorial carpets attributed to Heriz and the wider Tabriz context. The researchers reviewed more than one hundred examples and selected twenty-four for detailed analysis. Their imagery includes Waq-Waq trees, unusual human and animal forms, demons, dervishes, and other figures interpreted in relation to Qajar-period Sufi discourse.
These carpets are a rare, specialized subgroup. They should not be treated as the standard design of commercial Heriz rugs, and their attribution can require careful comparison between Heriz and Tabriz evidence. Their importance is that they show how broad and intellectually complex the region's weaving history can be.
Heriz, Serapi, and nearby market names
Serapi, also written Serape, is a market term connected with the broader Heriz tradition. Dealers often use it for older carpets with spacious drawing and particular color relationships, but usage is inconsistent. Serapi is not the name of a separate Iranian weaving town and should not be treated as a precise grade.
Iranica's entry on indigo discusses blue in Heriz production and notes carpets "also called Serape," confirming a historical connection between the labels without creating a universal classification rule. For the terminology and its problems, read our separate guide to the meaning of Serapi.
The same caution applies to nearby names. Bakhshayesh, Goravan, Mehraban, Karaja, and Sharabian can offer useful regional context, but a label should be supported by the rug's complete structure, design, date, and provenance.
Colors and dyes in Heriz rugs
Heriz carpets may include red, rust, dark and medium blue, ivory, warm brown, green, yellow, and salmon tones. Palette varies with period, dye lot, material, workshop, and individual production.
Iranica associates a medium blue with urban Heriz production and explains that indigo can produce different depths of blue. It also records the arrival of synthetic indigo in the late nineteenth century and notes that plant-derived and synthetic indigo yield the same chemical colorant. Visual inspection alone cannot always establish the source of a blue dye.
Abrash is a visible shift in color across part of a rug. It may result from a change in yarn or dye batch and can reveal the sequence of weaving. Abrash should be read with the rest of the rug. Color alone cannot prove that a rug is antique, naturally dyed, or Persian, and precise dye claims may require testing.
How to identify and evaluate a Heriz rug
Start with the complete object, not a single motif or sales phrase:
- Origin: Is the rug represented as Persian or Iranian, and what evidence supports the attribution?
- Structure: Examine the pile, warp and weft fibres, knot type, weft arrangement, sides, ends, and back.
- Design: Does the layout fit the wider Heriz vocabulary without being used as sole proof of origin?
- Condition: Check pile wear, exposed foundation, repairs, stains, corrosion, edge loss, end loss, and any areas that have been painted or rebuilt.
- Age: Is the date supported by physical evidence, documentation, and comparison, or is it only a broad dealer estimate?
- Use: Confirm exact dimensions, thickness, condition, and suitability for the intended room.
Ask for clear front, back, side, end, pile, and repair photographs when those views are not already available. A close view should supplement, not replace, a complete view. When age, origin, condition, or value materially affects the purchase, an in-person examination is preferable.
Persian Heriz versus Indo-Heriz
"Indo-Heriz" generally describes a rug woven in India using a design inspired by Persian Heriz carpets. It is an origin label, not another spelling of Persian Heriz. An Indian-made rug may be well constructed, but it should not be represented as woven in Iran.
Export-oriented carpet designs and palettes have been copied across countries for well over a century. Confirm the country of manufacture and judge the actual materials, structure, workmanship, and condition rather than relying on a Heriz-style medallion.
Are Heriz rugs valuable?
There is no fixed Heriz price per size or knot count. Value can change with origin, age, condition, dimensions, design, materials, fineness, color, provenance, rarity, and current market demand.
No rug is guaranteed to appreciate. An older rug with serious foundation damage may be less useful or valuable than a later example in strong condition. For insurance, estate planning, or a significant financial claim, use a qualified independent appraisal rather than a retail asking price or online description.
Living tradition and care
The Cheshni study treats local design vocabulary and the weaver's freedom to interpret a small pattern as forms of cultural knowledge. Recording old patterns, names, and methods matters because a standardized cartoon can preserve a design while still reducing the variations created through local practice.
For the rug itself, choose placement according to condition. Use a suitable rug pad, rotate the rug periodically, limit prolonged direct sunlight and moisture, and respond to spills according to the fibres and dyes involved. Do not assume that a dense or heavy rug is immune to insects, water, fire, harsh chemicals, or unsuitable cleaning.
Before washing or repairing an older Heriz, consult a specialist experienced with hand-knotted rugs. Poor washing, aggressive fringe replacement, overcasting, painting, or structural repairs can change both appearance and value.
