SaroukPopular, durable Persian city rugs from Sarouk, a town in central Iran about 50 km (31 miles) north of Arak, prominent from the 19th century and exported to Europe and America. A cotton foundation carries a medium-to-thick wool pile, at times with silk highlights, usually tied with the Persian knot (some older pieces use the Turkish knot) at medium-to-high density of up to about 320 knots per square inch (roughly 50 per cm²). Floral, medallion and allover designs, with some Herati, boteh and pictorial patterns, appear on beige, ivory, cream, navy or red fields, the red leaning toward orange or rust, usually with a thin secondary border. American Sarouks, woven mainly in the 1920s and 1930s, adapted designs and colors to U.S. taste, and many were re-dyed to a preferred rose red.See in the carpet dictionary is a village in the Farahan district of Markazi Province in central Iran, about 50 km north of the provincial capital, ArakRugs from Arak, a city in central Iran formerly called Sultanabad, and the villages around it, a weaving region that grew in the Qajar era when exports of Persian rugs to Europe and America thrived. Rug texts also use the city as a reference point: the town of Sarouk lies about 50 km (31 miles) to its north, and the Malayer villages lie between Arak and Hamadan. Older pieces of the area are still sold under the old name Sultanabad.See in the carpet dictionary. Arak itself was called 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 until the 1930s, and the old name still sits on rugs sold today. Sarouk, Farahan, Sultanabad and Mahal are all names from one stretch of the Arak plain rather than four unrelated places. In the trade the village name reaches well beyond the village itself: it describes the workshop style of the whole district, woven on town looms by trained weavers rather than by nomads. You will also meet the spellings “Sarough”, “Saruk” and “Saruq”, which all name the same weave.

Weaving here became widely known during the 19th century, when the wider rug trade noticed that these workshops were turning out unusually intricate drawing, rich color and a standard of finish that held steady from one piece to the next. That steadiness came out of how the work was organized: a drawn cartoon rather than a pattern carried in memory, several weavers at one 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 and the knots tied onto them. Hand-knotted rugs are made on simple looms, from those set up in weavers' homes to the compact, transportable ones of nomadic weavers, where every knot is tied by hand. Loom size sets rug size: nomads' small looms typically yield rugs no larger than about 4 x 6 or 5 x 7 ft (1.2 x 1.8 m or 1.5 x 2.1 m), city workshops with very large looms weave palace sizes, and the number of looms a workshop runs gauges its scale. 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, the industrial descendants, make machine-woven carpet.See in the carpet dictionary, and a master weaver keeping the line honest. The result is predictable in a way that village and tribal weaving rarely is, and more than any single motif it is what built the reputation of the name.

From the middle of the 19th century onwards the rugs went to Europe and then, in quantity, to the United States. Designs and colors were deliberately adjusted to what those markets wanted, and the adjustment was thorough enough to produce a named type of its own: the American SaroukA type of Sarouk woven mainly in the 1920s and 1930s, with patterns and colors adapted to what international buyers, above all in the United States, appreciated, and very popular there. It is also known as Mohajeran Sarouk. Its floral design later served as a model for newer Malayer and Mehraban rugs.See in the carpet dictionary, woven mainly in the 1920s and 1930s and hugely popular there. The trade also calls that group Mohajeran Sarouk, after another village of the Arak district, though the Mohajeran name is often kept for the finest weaving of the period. A related village type, Lilihan, was woven in part by Armenian weavers and carries a pattern of its own that American buyers took to.

Names shifted over the same period. Nineteenth-century pieces from this district were commonly sold as Farahan, after the district, and the Sarouk name took over during the 20th century, so older rugs are still catalogued either way. Quality did not run smoothly throughout. A dip in standards around the middle of the 20th century is well remembered, and it was the master weavers in the workshops themselves who noticed and pulled the level back up fairly quickly. A state-owned body also ran inspected workshops in the weaving cities, this district above all, controlling both woolA natural animal fiber used for the pile, and in some rugs also the foundation, of high-quality rugs. It is durable, resilient, stain resistant and flame resistant, feels soft and cushioned underfoot, insulates against cold, and takes up dye readily and holds it for many years. It also traps dust particles, which helps reduce allergic reactions. Quality depends above all on where the sheep graze: high-elevation pastures and good feed give thicker, oilier wool, with Manchester, New Zealand and Ghazni wools the best-known prized examples. Early-spring shearing and hand spinning (finer, softer thread than machine spinning) improve it further, while thin, dry wool from dead sheep goes into cheaper rugs.See in the carpet dictionary and weave; a weaver who made even a small error had to cut the work out and weave the section again.

Drawing is floral rather than geometric, laid out either around a central medallionA large motif at the center of a rug's field, around which the rest of the design is organized; the large central medallion is said to have been introduced in the Safavid era (16th-17th centuries). Floral medallions, typical of city rugs such as Tabriz, Kashan and Sarouk, are often read as a lotus blossom, and the motif has also been read as mirroring the interior dome of a mosque; geometric ones, often hexagonal or diamond-shaped, mark village and tribal rugs such as Heriz and Zanjan. A medallion may stand alone, come with four corner pieces, be flanked by smaller medallions above and below, or repeat down a runner. Rugs with 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 or as an all-over field, with the all-over floral and the 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 the two you meet most often. Within those layouts the classic Persian motifs all appear: herati, the fish-and-leaf lattice; botehA teardrop-shaped motif with a curved upper tip, ubiquitous in Persian and Kashmiri weaving for centuries. The Persian word is glossed as “budding flower or plant,” and the motif stands for growth and regeneration; it is also read as a cypress that bends in the wind but rarely breaks, a flame, a seed, a pine cone or a stylized almond. When Scottish mills began imitating Kashmir shawls in the 19th century, the boteh became known in the West as “paisley,” after the town of Paisley. In rugs it usually repeats throughout the field, notably in Tabriz, Sarouk, Kerman, Mashhad and Malayer pieces.See in the carpet dictionary, the curled almond shape that became paisley in Europe; gulAn octagonal or polygonal, stylized flower motif repeated in rows across the field of Turkmen rugs. The same repeat is typical of Baluchi rugs, where a flower sits inside each octagon, and of Bokhara rugs, woven chiefly in Pakistan after Turkmen models. In older Turkmen rugs each tribe (Tekke, Salor, Ersari and others) typically kept its own gul, so an expert can often tell the tribe from the motif, whereas modern pieces mix guls freely. The word means “flower” or “rose” in Persian, though the shapes are highly geometric rather than naturalistic.See in the carpet dictionary hennai, the henna flower; and afshan, literally scattered flowers, an all-over of symmetrical leafy branches, rosettes and paired sprays with no medallion to anchor the eye. Open fields, garden panels and vase designs are woven here as well, and pictorial rugs, which only a short list of workshop centers attempts at all: Tabriz most of them, then Kashan, Isfahan and here.

One detail is worth knowing before you look at a rug closely. A Sarouk's main border is usually shadowed by a much thinner secondary borderA narrow band running alongside the wide main border of a rug, framing it and completing the boundary around the field much as a frame surrounds a painting; it is also called a secondary border. Many Sarouk rugs, for example, wrap a much thinner secondary border around the primary one, and wide floral borders, as on some Tabriz and Kashan rugs, are often edged by narrow guards. The broad main border and its slim guards together form a hierarchy of bands that sets off the design.See in the carpet dictionary running around it, a narrow guard stripe framing the wide one, and once you have seen it you will pick it out across a room. The border is also almost always in a different color from the field, so the composition reads as a picture inside a frame rather than as one continuous surface running from edge to edge.

Fields are usually beige, ivory or cream on the light side, navy or a mid blue on the dark side, or red. The red is the useful one. A Sarouk red leans towards rust and orange rather than burgundy, and that tilt is one of the quickest ways to tell it apart from the cooler, deeper reds of Kashan or Tabriz. Highlights run to yellows and to many shades of blue and green. The palette overall is broad, comparable with Tabriz for sheer range, and largely built on natural dyes, which is why antique examples tend to look better with age rather than tired.

Underneath, the structure is the one city workshops settled on: a cotton foundation, rigid and stable, which holds a rug flat and square and resists the pull that sends a looser weave out of shape. 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 is wool, occasionally wool with silk used for highlights only. A silk foundationA rug base in which the warp and weft threads are silk rather than the usual cotton or wool. Silk is finer and thinner, so many more knots fit into each square inch; silk-based rugs typically run about 500 to 1,000 knots per square inch (roughly 78 to 155 per square centimeter). It is found mainly in fine traditional city rugs, most commonly Qum and Isfahan, and also in select Tabriz workshops and a special group of Yomut Turkoman rugs. The pile above may be wool, silk and wool, or pure silk.See in the carpet dictionary is not part of this tradition, and any claim of one deserves a second look. Some older pieces use kurk, a particularly soft and fine grade of wool, and are shorn short, so short-pile antique Sarouks do exist alongside the thicker modern ones.

Knotting is Persian, or asymmetrical, which lets the weaver pack knots tightly and follow a curve without the drawing turning blocky. Some older Sarouks were tied with the 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 instead. 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 runs from medium to high, reaching around 320 knots per square inchThe number of knots in one square inch of a hand-knotted rug (KPSI; 1 KPSI is about 15.5 knots per 10 x 10 cm), counted on the back with a ruler by multiplying the knots along one inch of height by those along one inch of width, averaged over two or three areas. More knots give sharper detail, like a higher-resolution screen, and, all else equal, somewhat more durability and a higher price, but density alone does not grade quality: Heriz and Bijar are durable at low to medium counts, while floral curvilinear designs blur without enough knots. Figures run from under about 80 for coarse tribal weaves such as Gabbeh and Qashqai, through roughly 120 to 225 for many village rugs and 300 to 700 for fine city rugs such as Nain and Isfahan, to 600 to 1,000 or more for pure silk Qum.See in the carpet dictionary at the top of the range, with plenty of sound pieces well below that; antiques in the low 200s already carry vines that swirl and flow rather than break into steps. Counts far above 320 belong to the very fine city weaves of QumPersian rugs from the city of Qum (Qom), a comparatively young weaving center whose rugs are known for the highest knot density of any Persian type. About nine in ten are pure silk on a silk foundation, at roughly 600 to 1,000 knots per square inch (KPSI; about 93 to 155 per cm²); the rest, with kork wool or silk-and-wool piles, run about 300 to 700 KPSI (about 47 to 108 per cm²). Designs are floral medallions, hunting scenes and pictorials, mostly in soft pastel, ivory, gold and green tones (a pistachio-green field is prized) on light or dark grounds. Newer rugs usually carry a workshop signature, older ones often do not. The local water is said to soften and brighten silk, so silk rugs from across Iran are sent there for washing.See in the carpet dictionary, Isfahan and Nain, not to this district.

Pile is medium to thick, which places these rugs with 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 wool's strength is traditionally credited to copper-bearing mountain water. The classic design is a large angular medallion with four corner pieces, sometimes an allover layout, in a rust red traditionally credited to copper minerals in the local river, with dark navy and cream. Bakshaish and Serapi, the latter now over a century old, are their older forms.See in the carpet dictionary, Mashad and BijarRugs from the city of Bijar in Kurdistan province, northwestern Iran, and the villages around it; the name covers both fine and coarse double-wefted pieces, woven by Kurdish tribes and, in workshops, Afshar weavers. Nicknamed the “iron rugs” of Iran, they are among the heaviest rugs for their size: double wefts, symmetrical (Turkish) knots, and rows beaten down hard, often while the wool is kept wet, give a thick, dense pile. Designs run from floral, Herati, and medallion to geometric, drawing on Isfahan and Kashan as well as Russian, Caucasian, and European sources (a French-style rose bouquet among them), in jewel tones of rust, red, beige, and navy. Bijars are often small rugs or runners, large sizes are rare, and the flat-woven ends and fringes are typically braided.See in the carpet dictionary rather than among the close-clipped city weaves. That matters in practice: a thicker pile takes footfall well, so a Sarouk suits a hallway, a living room or a dining room, where a darker field also forgives the occasional spill. Durability here is not a theoretical claim. Pieces of 40 and 50 years old turn up regularly in excellent condition, which is about as direct a test as a rug ever gets.

Few weaves cover the size range so completely. Small mats from about 60 by 90 cm, scatter sizes up to 120 by 180, the common room sizes of 150 by 210 and 180 by 270, large formats of 240 by 300 and 300 by 425, and oversize pieces beyond all belong to this district; the workshops have very large looms and deep resources, so commissioned and palace formats past roughly 3.6 by 5.5 metres are possible. Runners are a particular strength, from about 1.8 up to 6 metres, in narrow and wide widths, the wide ones turning up more often on older pieces.

A last point places the weave among its neighbours. Rugs from south-eastern Malayer follow Sarouk and Farahan drawing so closely that the two can be hard to separate, and the newer Mehraban style leans on Sarouk patterns, the American Sarouk design in particular. The traffic runs outward here: this drawing is copied by its neighbours more than it borrows from them. For a buyer it comes down to something plain enough. A Sarouk offers curvilinear floral drawing with a red you can recognize, on a foundation and a pile built to be walked on for decades.

A Persian rug is a rug 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 in Iran, and the tradition behind it is the oldest documented anywhere. The earliest surviving carpet, the Pazyryk rugThe oldest known pile carpet in the world, woven around the 5th century BC and discovered in 1949 in the frozen tomb of a Scythian noble in Siberia's Altai Mountains. Grave robbers left the burial mound open, so cold and moisture froze the chamber and sealed the carpet in ice for some 2,500 years. Its symmetrical knots, about 36 per square centimeter (roughly 230 per square inch), show that carpet weaving was already a mature art in antiquity. It is often described as the oldest Persian rug and as early evidence of tribal weaving, a craft that began as protection against cold and damp. It is displayed in the Hermitage Museum in St. Petersburg.See in the carpet dictionary, was found preserved in a frozen burial mound and dates to the fifth century BC — roughly 2,500 years ago — and it is already accomplished work, not a beginner's craft. What began as warm, hard-wearing floor coverings for tribal households grew, over those centuries, into the art form that every other rug-weaving country has borrowed from.

Two later chapters shaped what a Persian carpet looks like today. Under the Safavid dynastyThe Persian ruling house that reigned from 1501, beginning with Shah Ismail, into the 1730s, whose court patronage of painting, calligraphy and weaving made this the golden age of Persian rugs. Many museum and top-auction masterpieces come from the era, with Tabriz, Herat, Kashan and Kerman the largest centers. As patterns grew more complex, designers, often miniature painters, became separate from the weavers who worked from their drawings; the large central medallion, curvilinear and geometric layouts and richer flowers and vines became hallmarks, and patterns were standardized for export to Asian and European markets. The Afghan invasion of Isfahan in 1722 interrupted weaving in the main manufacturing centers for several years, though tribes and villages carried on.See in the carpet dictionary, from 1501 to 1732, the court promoted weaving alongside painting and calligraphy, and the workshops of Tabriz, HeratRugs from Herat, a historic city in western Afghanistan that was among the largest rug-producing centers of the Safavid period (16th to early 18th century), alongside Tabriz, Kashan and Kerman. The city also gives its name to the Herati design, a repeated diamond holding a small flower or leaves, with curved leaves at its sides, which is said to have originated there and is still woven in many Persian rugs.See in the carpet dictionary, Kashan and Kerman produced the masterpieces that now sit in museums. This is when the great central medallionA large motif at the center of a rug's field, around which the rest of the design is organized; the large central medallion is said to have been introduced in the Safavid era (16th-17th centuries). Floral medallions, typical of city rugs such as Tabriz, Kashan and Sarouk, are often read as a lotus blossom, and the motif has also been read as mirroring the interior dome of a mosque; geometric ones, often hexagonal or diamond-shaped, mark village and tribal rugs such as Heriz and Zanjan. A medallion may stand alone, come with four corner pieces, be flanked by smaller medallions above and below, or repeat down a runner. Rugs with 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 appeared, and when designs grew elaborate enough that a separate designer — often a miniature painter — drew the pattern onto a cartoon for the weaver to follow. The second chapter came in the nineteenth century, under the Qajar dynastyThe era of the Qajar dynasty, which ruled Persia in the 19th century and produced the largest rug output in Persian history. Weaving revived after the turbulence of the 1700s that had halted the main manufacturing centers, and exports to Europe and America thrived, with England and Germany the biggest buyers. Newer centers such as Sultanabad and Kashan rose alongside Tabriz and Kerman, and European and American companies set up their own manufacturing hubs in Persia. Rugs from these large factories follow standardized, easily recognized designs, unlike village and tribal rugs, whose weavers still design their own patterns.See in the carpet dictionary, when production reached its historical peak, exports to Europe and America boomed, and the workshop industry whose descendants still weave today took its modern shape.

The trade sorts Persian rugs into three families. City rugs — Tabriz, Kashan, Kerman, Nain, Isfahan — are woven in workshops from a drawn design, carry the highest knot densities and come in the widest range of colors, sizes and patterns. Village rugs such as 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 wool's strength is traditionally credited to copper-bearing mountain water. The classic design is a large angular medallion with four corner pieces, sometimes an allover layout, in a rust red traditionally credited to copper minerals in the local river, with dark navy and cream. Bakshaish and Serapi, the latter now over a century old, are their older forms.See in the carpet dictionary, BakhtiariColorful rugs of the Bakhtiari, a Zagros Mountains tribe that was nomadic until much of it settled southwest of Isfahan in the 19th century and whose weaving now spreads across more than 200 villages; smaller pieces tend to be tribal work and larger ones come from the region's villages. The foundation is usually cotton under a wool pile from the tribe's own sheep, though some small tribal pieces are wool throughout, and every row is beaten down so hard that the pile ends up dense and long-lasting. The signature layouts are the garden panel design (Khesti, also spelled Kheshti), a grid of framed squares that each show a garden scene meant as a view of paradise, and the medallion-and-corner design with a semi-geometric center medallion. Deep red and dark navy are the usual field colors.See in the carpet dictionary and KarajaVillage rugs from a group of villages in the Azerbaijan region of Iran, at the western edge of the Heriz weaving area and named for the village of Karaja at their center. Wool pile on a cotton foundation (very old pieces may have a wool one), Turkish knot and single weft, so the pile is thinner and softer than the usually double-wefted Heriz, and knot density is low to medium. Two bold geometric medallions with hook-like edges typically alternate down a runner, often on a different ground color with each repeat, and on wide rugs the repeated medallions read as a geometric allover, in orange-reds, blues, creams and browns. Their soft, thin pile and great lengths, some over 20 feet (6 m), make them popular as hallway and stair runners.See in the carpet dictionary sit in between, mostly geometric and largely woven from memory. Tribal rugs — Baluch, TurkomanTribal rugs woven by Turkoman (Turkmen) nomads, whose forebears came from the Afghan and Uzbek region and who later settled in the Turkmen region of Iran. Rows of octagonal guls (“flowers”) cover a deep red, reddish-brown or occasionally cream field, accented in black, blue, green or beige; prayer designs also occur. Foundation and pile are usually wool, said to come from the soft undercoat of Karakul sheep, though a cotton foundation is occasionally used. In older pieces each tribe kept its own gul design, whereas newer rugs freely mix them. Turkoman designs inspired Bokhara and Khal Mohammadi rugs and are the Persian design closest to Baluchi work, which they predate; the low-to-medium pile suits places where doors swing over the rug.See in the carpet dictionary, QashqaiTribal rugs woven by the Qashqai, a nomadic tribe of southwestern Iran that unites Turkic, Arab, Kurdish and Lur groups and has lived in the region since at least the 16th century. Designs come from memory rather than written plans, pairing geometric and medallion layouts, occasionally in a simpler, sparsely detailed form, with animals, plants and household objects, in jewel-tone reds, saffron gold and indigo, often on deep red or dark navy grounds. The thick, hard-weaving wool of the tribe's own flocks is durable yet soft, forming a medium-height, dense pile on a cotton or wool foundation that suits busy areas; compact looms keep sizes small, typically 4 x 6 ft (1.2 x 1.8 m) or 5 x 7 ft (1.5 x 2.1 m) plus runners.See in the carpet dictionary, each named after the people who weave it — are made on small portable looms, so they run smaller, and their bold geometric drawing comes from the weaver's own head rather than from paper.

The design vocabulary draws on a deep stock of motifs: 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 palmettes, flowing arabesques, the small repeating Herati patternA 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.See in the carpet dictionary, medallions, garden and tree-of-life compositions. These combine with regional habits into styles a practised eye can place at a glance, from the bold geometric medallions of Heriz to the fine curvilinear florals of Isfahan.

The classic palette is built on natural dyes: 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, saffron yellows and soft ivory tones, settled into combinations refined over centuries. Natural dyes age gracefully, mellowing into the patina that older rugs are prized for, and slight shifts of tone between dye batchesA single batch of dye, together with the yarn colored with it, all of which takes the same shade. Natural dyes are made in small artisanal batches, and when one runs out the replacement cannot be matched exactly, so yarn from different lots differs slightly in tone. In a finished rug the difference shows as the color shifts known as abrash, which is read as a sign of hand dyeing, whereas a perfectly flat, uniform color suggests synthetic dyes and machine making.See in the carpet dictionary — the effect called abrashSubtle shifts in color within a handmade rug, often visible as horizontal bands across the field. They arise because successive dye batches never match exactly, because differences in the wool's fat and oil content make colors change unevenly with age, and, in cream areas woven from undyed wool, because the fiber changes tone as it ages. Abrash often grows more distinct with age, so in an older rug it counts as a sign of natural dyes and hand production rather than a fault, while a newer rug is still checked for even color. Machine-made and some new hand-knotted rugs imitate it on purpose.See in the carpet dictionary — are a mark of small-batch natural dyeing, not a flaw.

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 is almost always woolA natural animal fiber used for the pile, and in some rugs also the foundation, of high-quality rugs. It is durable, resilient, stain resistant and flame resistant, feels soft and cushioned underfoot, insulates against cold, and takes up dye readily and holds it for many years. It also traps dust particles, which helps reduce allergic reactions. Quality depends above all on where the sheep graze: high-elevation pastures and good feed give thicker, oilier wool, with Manchester, New Zealand and Ghazni wools the best-known prized examples. Early-spring shearing and hand spinning (finer, softer thread than machine spinning) improve it further, while thin, dry wool from dead sheep goes into cheaper rugs.See in the carpet dictionary, and the wool decides much of the rug's quality. The best fleece comes from high-altitude flocks, where it grows thicker and richer in natural oils; spring-sheared wool beats the autumn clip, and hand-spun yarnWool yarn spun from cleaned, carded fleece by hand or on a manual wheel rather than by machine, after which the spun threads are twisted together into thicker, stronger strands before dyeing. It gives finer, softer threads than machine spinning, so the wool feels softer and looks shinier, and hand spinning is said to preserve the wool's natural lanolin. It is usual in Kazak and Peshawar rugs woven in Pakistan and in Afghan Khal Mohammadi rugs, all of which are also colored with natural dyes.See in the carpet dictionary gives a finer, softer thread than machine spinning. Fine pieces add silk highlights to a wool pile, and the finest are woven in pure silk. Foundations are usually cotton in city weaving, wool in tribal and older pieces, silk at the very top of the range.

Every knot is tied by hand, one at a time, in one of two forms: the asymmetric Persian 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, usual in central and eastern Iran, or the symmetric 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, common in the north-west ever since Seljuk weavers introduced it in the eleventh and twelfth centuries. A large carpet holds in the region of two million knots and can occupy a weaver for about a year.

Knot densityThe number of knots in one square inch of a hand-knotted rug (KPSI; 1 KPSI is about 15.5 knots per 10 x 10 cm), counted on the back with a ruler by multiplying the knots along one inch of height by those along one inch of width, averaged over two or three areas. More knots give sharper detail, like a higher-resolution screen, and, all else equal, somewhat more durability and a higher price, but density alone does not grade quality: Heriz and Bijar are durable at low to medium counts, while floral curvilinear designs blur without enough knots. Figures run from under about 80 for coarse tribal weaves such as Gabbeh and Qashqai, through roughly 120 to 225 for many village rugs and 300 to 700 for fine city rugs such as Nain and Isfahan, to 600 to 1,000 or more for pure silk Qum.See in the carpet dictionary is the figure newcomers fixate on, and the finest silk-foundation pieces do reach as much as 1,000 knots per square inch. But 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 only matters as far as the drawing demands it: a curvilinear Isfahan needs a fine weave to stay sharp, while a geometric Heriz is famously durable at a modest count. Material, symmetry, color harmony and condition say more about quality than any single number.

Persian carpets settle into modern rooms as naturally as classical ones, as a focal point in a living room, a foundation under a dining table or a quieter accent in a bedroom. Care is undemanding: gentle vacuuming without a rotating brush, an occasional turn for even wear, and a professional wash about every five years — sooner in a hallway or entrance, less often in a quiet room.

A hand-knotted Persian rug tends to outlast its owners. Pieces a century old regularly survive in fine condition, their colors settled and their pile supple, often looking better than when they left 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 and the knots tied onto them. Hand-knotted rugs are made on simple looms, from those set up in weavers' homes to the compact, transportable ones of nomadic weavers, where every knot is tied by hand. Loom size sets rug size: nomads' small looms typically yield rugs no larger than about 4 x 6 or 5 x 7 ft (1.2 x 1.8 m or 1.5 x 2.1 m), city workshops with very large looms weave palace sizes, and the number of looms a workshop runs gauges its scale. 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, the industrial descendants, make machine-woven carpet.See in the carpet dictionary. A well-chosen, well-kept rug holds its worth and passes down as a family heirloom rather than being replaced — which is precisely what the knots, the wool and the dyes were always for.
