Rey (ری), the Rhagae of classical geography, lies on the plain just south of Tehran in northern Iran, under the southern flank of the Alborz. For most of its life it was one of the great cities of the Iranian plateau, Median, Parthian, Sasanian and then a Seljuk capital, until the Mongols sacked it in 1220 and it never recovered as a city in its own right. What survives is Shahr-e Rey, a southern district of the Tehran metropolitan area built around the shrine of Shah Abd al-Azim. Rugs carrying this origin therefore come from the Tehran plain and its workshops rather than from a village with a single inherited pattern book.

It is worth being straightforward about what that means. Rey is not one of the classical named weaves, and no separate Rey design canon exists in the way one exists for Tabriz, Kashan or Kerman. The weaving town of Tehran Province with a documented character of its own is Varamin, about 40 km south-east of Tehran, known for all-over mina khaniAn all-over repeating pattern of round flowers linked by a diamond lattice of vines, usually with the blossoms rendered in white or yellow on a dark blue or red ground. Beloved in Kurdish, Baluchi, and northwest Persian weaving, the design reads from a distance as a field of stars. Its name is popularly traced to a legendary patron, Mina Khan.See in the carpet dictionary fields, while Tehran itself produced only a small quantity of fine workshop work from the late nineteenth century onwards. A rug from this origin is best read from what it actually shows rather than from the place name attached to it.

Knot type is the most reliable of those readings. Central, eastern and southern Iran work the asymmetrical knotThe asymmetrical knot of hand-knotted rugs, the counterpart of the symmetrical Turkish (Ghiordes) knot. The weaver wraps the yarn around one warp thread and passes it under the neighboring one, usually working by hand without a hook. On the back of the rug the knots look staggered or diagonal rather than like tidy squares, and the pile feels softer; the knot permits finer detail and higher knot density. In Iran, a rule of thumb ties it to the central, eastern, and southern rugs (Kashan, Isfahan, Nain, Kerman), while the northwest and west favor the Turkish knot, though exceptions exist. Fine curvilinear florals are often credited to it, but Turkish-knot rugs can be just as intricate.See in the carpet dictionary, also called the Persian, farsi or Senneh knot, and the Tehran plain sits inside that zone rather than in the Turkish-knot north-west. The yarn wraps one warp and passes under the warp beside it, and it is tied with the fingers rather than with a hook, which is what lets the weaver hold fine detail and curved drawing. On the back it reads as slightly staggered and diagonal. The symmetrical or Turkish knotOne of the two main knots of hand-knotted rugs, also called the symmetrical knot (the other being the asymmetrical Persian or Senneh knot). The yarn is looped around two adjacent warp threads with both ends emerging between them, so the back shows small, even, squarish knot heads; weavers often tie it with a hook. Named after the town of Ghiordes (modern Gördes) in Turkey, it is typical of Turkey, the Caucasus and northwestern Iran (Tabriz, Bijar, Heriz, village Hamadan), where Seljuk Turks are said to have introduced it, and gives a durable, precise pile. The Persian knot is often credited with finer detail, yet knot type is a tendency, not a limit: Tabriz rugs woven with the Turkish knot reach about 500 knots per square inch (roughly 78 per cm²).See in the carpet dictionary wraps two warps at once and shows as even little rectangles; it belongs to Turkey, the Caucasus and north-west Iran.

Underneath the pileThe surface of a rug or carpet, made of upright fibers in cut tufts or loops. In a hand-knotted rug it is formed by the cut ends of thousands of wool or silk knots tied onto the warp row by row, trimmed lightly during weaving and given its final height by shearing at finishing. Pile thickness, measured from the back of the rug to the top of the pile, typically runs from low, about 1/8 to 1/4 inch (3 to 6 mm), to high, about 1/2 to 5/8 inch (13 to 16 mm). Fine, dense designs are cut short to keep the pattern sharp; higher pile suits traffic and heavy furniture, lower pile suits door clearance and humid rooms.See in the carpet dictionary sits a structure worth knowing by name. The warp runs the length of the rug and is the first thing laid on the loomThe frame on which the warp (vertical) threads are strung first and held under tension so the weft (horizontal) threads can be interlaced through them. Hand-knotted and hand-woven rugs are made on simple looms, such as upright village looms or the portable ground looms of nomadic weavers, where every knot is tied by hand. Loom size sets rug size: nomads' compact looms yield small rugs, city workshops with very large looms can weave palace sizes, and wooden looms in tribal and village weaving expand and contract over time, one cause of crooked rugs. Power looms such as Wilton, Axminster, and Jacquard are the industrial descendants, used for machine-woven carpet.See in the carpet dictionary; the weft crosses it horizontally, passing in and out between the rows of knots, and may be single or double. Together they form the foundation, and the knots tied around the warp make the pile you see and walk on. The fringes are not a trim but the warp itself emerging at the ends, and the flat kilimA flat-woven rug with no pile, traditionally made in Turkey, Iran, Afghanistan, and the Balkans. Colored weft threads are interlaced with the warp without knots, so both sides look alike. The fibers are typically wool, cotton, or goat hair, and natural dyes often give slight shade variations that are normal, not flaws. Its low profile clears doors easily, and it can hang as wall art. In a knotted rug, "kilim" also names the flat-woven band at each end, where extra weft rows secure the ends beside the fringe.See in the carpet dictionary band between pile and fringe is extra weft locking those ends closed. The side edges are overcast, wrapped around the outermost warps.

Counted on the back of the rug, knots per square inchThe number of knots in one square inch of a hand-knotted rug (KPSI, or knot density; 1 KPSI is about 15.5 knots per 10 x 10 cm), counted on the back by multiplying the knots along one inch of height by those along one inch of width, averaged over two or three areas. More knots show finer, sharper detail, like a higher-resolution screen, and usually add cost and some durability, but density alone does not grade quality. Rough bands run under about 80 for the coarsest tribal weaves, 80 to 200 for sturdy village and city rugs, 200 to 400 for fine floral city rugs, and 400 to 1,200 or more for the finest silk and silk-foundation pieces.See in the carpet dictionary (KPSI) describes how tightly it is woven, roughly the way pixels describe a screen. Because densityA measure of how tightly a carpet is packed. In machine-made carpet it describes the fibers in the pile and is calculated by multiplying the face weight by 36 and dividing by the pile height; higher density generally indicates better durability and performance. In hand-knotted rugs it means knot density (KPSI, knots per square inch), counted on the back and averaged over several areas (150 KPSI is about 23 knots per cm²). Like image resolution, higher density allows finer curves and sharper designs, usually with a lower-trimmed pile and more labor, but it is not the sole measure of quality: bold geometric village rugs are made at low to medium density.See in the carpet dictionary changes with the motif, faces and small florals running higher than open ground, it is honest to count two or three patches and average them. Numbers are lower than newcomers expect: a good antique Kashan of curvilinear urban drawing can measure around 240 knots per square inch and still be a medium weave that carries its pattern cleanly. Density earns its keep only where the drawing demands it, since curvilinear and floral patterns need it and geometric ones do not.

Nor is a high count by itself a mark of quality. All else being equal a denser rug is somewhat harder wearing, but HerizBold village rugs from the Heriz area of northwestern Iran, near Tabriz, and the best-known of all Persian village rugs. A coarse, tough wool pile on a cotton foundation, usually double-wefted for extra thickness, and a low-to-medium knot density (commonly quoted at about 120 to 170 KPSI, roughly 1,900 to 2,600 per 10 by 10 cm) make them very durable. The classic design is a large angular medallion with four corner pieces, sometimes an allover layout, in a rust red attributed to copper minerals in the local river, with dark navy and cream. Bakshaish and Serapi are their older forms.See in the carpet dictionary and BijarRugs from the city of Bijar in Kurdistan province, northwestern Iran, and the villages around it, woven by Kurdish tribespeople and, in workshops, Afshar weavers; the name covers both fine and coarse pieces. Nicknamed the "iron rugs" of Iran, they are among the heaviest rugs for their size, with a dense pile from double wefts, symmetrical (Turkish) knots, and rows beaten down hard, often while the wool is kept wet. Designs run from floral, Herati, and medallion to geometric, in jewel tones of rust, red, beige, and navy. Most are small rugs or runners, and the fringes are typically braided.See in the carpet dictionary are woven at low to medium density and are among the toughest Persian rugs made, while plenty of very fine new work is mediocre and plenty of low-density antiques are valuable. WoolA natural animal fiber used for the pile, and in some rugs also the foundation, of high-quality rugs, prized for its durability, resilience, natural stain resistance and fire-retardant properties. It feels soft and cushioned underfoot, insulates against cold, and takes up dye readily and holds it for many years. Quality depends above all on where the sheep graze: high-elevation pastures give thicker, oilier wool, and Manchester, New Zealand and Ghazni wools are the best-known prized examples. Spring shearing and hand spinning improve it further, while thin, dry wool taken from dead sheep ends up in cheaper rugs.See in the carpet dictionary quality, the evenness of the weave, the confidence of the drawing and the dyes tell you more than the number does. Treat density as one reading among several rather than as a score out of ten.

Wool carries most of what a buyer actually feels. It is soft underfoot, resists staining, takes dye deeply so colours hold their strength for years, insulates against a cold floor and traps dust rather than letting it circulate, which is why wool rugs suit households that are sensitive to it. The fleece is sheared, the spring clip counting as the best grade, then scoured to wash out grease and dirt, carbonised to clear the plant matter left in it, carded so the fibres lie parallel, and finally spun into yarn by wheel or by hand. Well-prepared spring wool feels noticeably different in the hand.

Design tells you which tradition a piece belongs to more reliably than its origin label does. A floral medallionA floral rug built around one central medallion, either a single large flower or a cluster of small blooms joined into one shape, often echoed by smaller medallions above, below and beside it. The medallion is traditionally said to stand for the sacred lotus. Because it takes up field space, the flowers and branches are smaller and thinner than in allover floral rugs. The design is typical of Tabriz, Kerman, Sarouk and Kashan, and its strong center makes it a natural focal point of a room.See in the carpet dictionary, its centre built from one large blossom or from many small ones gathered into a single form, with satellite medallions above, below and to the sides and thin branching stems across the field, is the language of urban workshops. The lotus stands behind that central form, a sacred flower in the tradition. A blockier geometric medallionA layout in which one large angular medallion stands at the center of the field, with separate corner designs and a much lighter pattern over the remaining ground, so the medallion is the clear focal point. Smaller geometric medallions often sit above and below the main one. It is typical of village and tribal rugs such as Heriz, Abadeh, Zanjan, Karaja and Qashqai, and is the angular counterpart of the floral center medallion.See in the carpet dictionary with filled corner spandrels and a lighter field around it comes instead from village and tribal looms, where the drawing is remembered rather than set out on a cartoon.

History here is a story about a city rather than about a loom. Rey was a major Seljuk centre in the eleventh and twelfth centuries, the period when Turkic weavers brought the symmetrical knot into Persia, an influence still legible in Tabriz, Azerbaijan and Hamadan. The Mongol sack ended that city, and the weaving centres named in every account of Persian carpets lie elsewhere: Tabriz, Herat, Kashan and Kerman under the Safavids, then Tabriz, SultanabadAntique Persian carpets from Sultanabad, the former name of the Arak region of Iran, a newer weaving center that flourished under the Qajars in the late 19th and early 20th centuries and supplied European and American buyers. Their typical layout is an allover field of oversized palmettes, lotus blossoms, floral sprays and angular vines, recalling the Shah Abbasi pattern in a rustic village manner rather than the precise curvilinear drawing of city rugs. Indigo or midnight blue with rust or brick red, gold and olive is a classic palette. Because Sultanabad no longer exists under that name, antique examples are scarce and command higher prices.See in the carpet dictionary, Kerman and Mashhad as the manufacturing hubs of the nineteenth-century Qajar peak, when English and German demand drew European and American firms into Persian production.

Placing one of these rugs is straightforward. A medallionA large motif at the center of a rug's field, around which the rest of the design is organized. Floral medallions, typical of city rugs such as Tabriz, Kashan and Sarouk, are often read as a lotus blossom; geometric ones, often hexagonal or diamond-shaped, mark village and tribal rugs such as Heriz and Zanjan. A medallion may stand alone, pair with four corner pieces, be flanked by smaller medallions above and below, or repeat down a long field such as a runner. Rugs with a pattern repeating across the whole field and no central motif are called allover. In a well-made rug the medallion sits at the center and the corners mirror one another, as closely as handwork allows.See in the carpet dictionary design works as the focal point of a room, centred on the floor itself or on the table and seating, because the eye settles where the medallion does; an all-over field is more forgiving of furniture standing on it. Turn the rug over before you decide, since the knot, the density and the regularity of the weave are all visible at once on the back, and check the pile height and the firmness of the edges while you are there. Those four things predict how a rug will live with you better than any label.

Persian carpets stand as living masterpieces of textile art, representing over 2,500 years of cultural heritage and unparalleled craftsmanship that has influenced rug making worldwide. These extraordinary floor coverings transform spaces into galleries of woven artistry, each piece telling its own unique story.

The distinguishing characteristics of authentic Persian carpets lie in their hand-knottedA rug construction in which the weaver ties each knot of wool or silk pile yarn by hand around adjacent warp threads on a loom, then runs a weft through the row and beats it down. The cut knot ends form the pile, the warps and wefts form the foundation, and the warp ends become the fringe. A rug can take months or even years, and the work leaves subtle irregularities: patterns not perfectly symmetrical, opposite edges a few inches different in length, an uneven fringe. Authentic Persian, Oriental and Turkish rugs are hand-knotted, unlike hand-tufted rugs (sometimes sold as “handmade”) and machine-made ones, whose backs feel stiff and evenly aligned.See in the carpet dictionary construction, with skilled artisans tying each knot individually - often up to 1,000 knots per square inchThe number of knots in one square inch of a hand-knotted rug (KPSI, or knot density; 1 KPSI is about 15.5 knots per 10 x 10 cm), counted on the back by multiplying the knots along one inch of height by those along one inch of width, averaged over two or three areas. More knots show finer, sharper detail, like a higher-resolution screen, and usually add cost and some durability, but density alone does not grade quality. Rough bands run under about 80 for the coarsest tribal weaves, 80 to 200 for sturdy village and city rugs, 200 to 400 for fine floral city rugs, and 400 to 1,200 or more for the finest silk and silk-foundation pieces.See in the carpet dictionary in the finest pieces. This meticulous process creates rugs of exceptional densityA measure of how tightly a carpet is packed. In machine-made carpet it describes the fibers in the pile and is calculated by multiplying the face weight by 36 and dividing by the pile height; higher density generally indicates better durability and performance. In hand-knotted rugs it means knot density (KPSI, knots per square inch), counted on the back and averaged over several areas (150 KPSI is about 23 knots per cm²). Like image resolution, higher density allows finer curves and sharper designs, usually with a lower-trimmed pile and more labor, but it is not the sole measure of quality: bold geometric village rugs are made at low to medium density.See in the carpet dictionary and durability, explaining their ability to last for generations while growing more beautiful with age.

Each Persian carpet's design vocabulary draws from a rich tradition of motifs: elegant Shah AbbasiA classic Persian floral style named after the Safavid ruler Shah Abbas, which began as a royal court pattern about 400 years ago. Its main features are stylized, feather-like palmette leaves and lotus flowers, the lotus being an ancient symbol of long life, arranged in strict symmetry with scrolling ornament around a central medallion, often a rosette. Early examples favored deep reds and blues, while later rugs in this style often turn to muted neutral tones. The design appears in Kashan, Nain and Tabriz rugs.See in the carpet dictionary flowers, graceful arabesques, intricate Herati patterns, and magnificent medallions. These elements combine with regional variations to create distinct styles, from the bold geometric patterns of HerizBold village rugs from the Heriz area of northwestern Iran, near Tabriz, and the best-known of all Persian village rugs. A coarse, tough wool pile on a cotton foundation, usually double-wefted for extra thickness, and a low-to-medium knot density (commonly quoted at about 120 to 170 KPSI, roughly 1,900 to 2,600 per 10 by 10 cm) make them very durable. The classic design is a large angular medallion with four corner pieces, sometimes an allover layout, in a rust red attributed to copper minerals in the local river, with dark navy and cream. Bakshaish and Serapi are their older forms.See in the carpet dictionary to the delicate floral compositions of Isfahan.

The color palette of Persian carpets represents a masterclass in natural dyeing techniques. Rich madderThe root of the madder plant (Rubia tinctorum), a natural red dye and the source of the terracotta tones in Persian and Oriental rugs. Together with indigo and walnut husks it is among the plant dyes used to color the wool, bonding to its natural lanolin. Slight shade variations within one color area, known as abrash, are normal in rugs dyed this way.See in the carpet dictionary reds, indigo blues, vibrant saffron yellows, and subtle ivory tones come together in harmonious combinations that have been perfected over centuries. These natural dyes age gracefully, developing a sought-after patina that enhances the carpet's character.

Superior materials form the foundation of every genuine Persian carpet. The finest woolA natural animal fiber used for the pile, and in some rugs also the foundation, of high-quality rugs, prized for its durability, resilience, natural stain resistance and fire-retardant properties. It feels soft and cushioned underfoot, insulates against cold, and takes up dye readily and holds it for many years. Quality depends above all on where the sheep graze: high-elevation pastures give thicker, oilier wool, and Manchester, New Zealand and Ghazni wools are the best-known prized examples. Spring shearing and hand spinning improve it further, while thin, dry wool taken from dead sheep ends up in cheaper rugs.See in the carpet dictionary, sourced from high-altitude sheep and spun by hand, provides remarkable resilience and a luxurious feel. In prestigious pieces, silk highlights add shimmer to wool backgrounds, while all-silk carpets offer unmatched luminosity and refinement.

Persian carpets adapt beautifully to both traditional and contemporary settings. Their timeless designs complement modern minimalist spaces as effectively as they enhance classical interiors. Whether used as striking wall-to-wall installations, elegant room-sized carpets, or dramatic wall hangings, these pieces command attention while creating atmosphere.

The investment potential of Persian carpets is well-documented, with fine examples appreciating in value over time. Each piece represents a tangible asset that combines aesthetic appeal with historical significance. The finest examples are often considered alternative investments, particularly those from renowned weaving centers or featuring unusual designs.

Maintenance of Persian carpets reflects their premium status. Their natural materials respond well to professional cleaning, while regular careful vacuuming and rotation ensure even wear. Many pieces actually improve in appearance over decades, developing subtle variations in color and acquiring a lustrous sheen.

Owning a Persian carpet means participating in one of humanity's oldest and most refined decorative arts traditions. These pieces represent more than floor coverings; they are portable works of art that bring warmth, sophistication, and cultural richness to any environment they grace.
