Shahr-e Babak sits in the north-western corner of Kerman province in Iran, roughly 250 km by road from Kerman city and high on an arid plateau at about 1,800 meters, on the margin where Kerman meets Yazd. Its name reads as the city of Babak, traditionally taken to be Babak or Papak, the father of Ardashir I, who founded the Sasanian dynasty; he is not the later rebel Babak Khorramdin, whose fortress stands far away in Azerbaijan. Beyond weaving, the district is known for Meymand, the rock-cut cave village inscribed by UNESCO in 2015, and for copper mining at Meydook. Rafsanjan lies to its east and Sirjan to its south.

That geography matters more than the province name printed on a label. This whole north-western quarter of Kerman is Afshar country, worked by a Turkic tribal people whose herds and looms have been on the plateau for centuries, and Afshar weaving is a tradition of its own rather than a village offshoot of the Kerman city workshops. Those workshops produce fine curvilinear rugs drawn out on a cartoon by a professional designer, with a celebrated master-dyer trade behind them. Shahr-e Babak weaving comes from the other side of Persian rug-making entirely: tribal and village looms, woolSee in the carpet dictionary-led, drawn in straight lines and angles.

Weaving here sits at the settled end of that tradition. Fully nomadic weavers move with their flocks through spring, summer and autumn and only weave once they have stopped for the winter, which limits them to small looms and whatever wool and dyestuff the season has provided. A settled district has permanent looms in several sizes, a steadier supply of dyed yarn and better tools, so the weaving is more regular and the range of formats wider. What does not change is the absence of a blueprint. The drawing is carried in memory, learned by sitting beside an older weaver and repeating what her hands do.

Design in the Afshar districts is therefore geometric, and reads as a family of repeated units rather than a single flowing composition. Expect an angular medallionSee in the carpet dictionary, or two or three stacked up the field, with hooked and latch-hook edges, stepped outlines and small filler motifs packed into the ground around them. Allover repeats are common, as are stylized birds, rosettes and diamond lattices. Borders are usually several narrow bands rather than one wide one. The weaver's own eye shows in small asymmetries: a motif that changes color halfway up the field, or a border that adjusts itself to fit the corner.

Among those motifs the botehSee in the carpet dictionary is the one most buyers recognize on sight, and it is a staple right across the Afshar districts. The word in Farsi means a bud or a young plant, and in Persian culture the shape stands for growth and regeneration; in a rug it reads as a teardrop, flame or pine-cone with a bent tip, repeated in rows across the field or gathered inside a medallion. City workshops draw it with soft curves. On an Afshar loomSee in the carpet dictionary it comes out square-shouldered and outlined, each one slightly different from its neighbor, often set in tidy diagonal rows against a plain ground.

Wool from the Kerman plateau is the material that gives the province's rugs their standing. Sheep here grow a coarse outer fleece over a soft, fine inner coat known as kork, and it is the kork that goes into the good rugs of the region. Spun by hand it takes dye deeply and keeps a soft luster. Because tribal and village weavers traditionally clip, spin and dye their own supply, the yarn in an older piece can vary subtly in thickness, which is what gives the pileSee in the carpet dictionary its faintly irregular, hand-made surface.

Color follows a shorter and more deliberate scale than the city rugs of the same province, which can carry anywhere between fifteen and thirty separate shades. Village and tribal dyeing works with what grows nearby and with the reliable classics: madderSee in the carpet dictionary for the red-to-rust range, indigo for the mid and dark blues, walnut huskSee in the carpet dictionary and other barks for browns, with undyed ivory and natural brown fleece left as they came off the sheep. The result is a short palette used in strong contrasts. AbrashSee in the carpet dictionary, the soft horizontal banding where one dye lotSee in the carpet dictionary ends and the next begins, is normal here and is not a fault.

Construction is wool-forward. The pile is wool throughout, and the foundation may be wool or cotton, with wool more usual in older and smaller pieces and cotton more common in later and larger ones; both are correct for the district. Knotting is moderate rather than fine by design, sitting above purely nomadic work and below the city workshops, because the drawing is geometric and does not need a dense grid to come out cleanly. The result is a relatively thick, robust rug that takes daily traffic well and is easier to live with than a fine silk-and-wool piece.

Formats tend to be modest. Afshar looms turn out a great many small and medium rugs, scatter sizes and the near-square pieces that began life as bag faces and animal covers, rather than the room-filling carpets made to order in the cities. That suits a modern home: a hallway, a bedside, the space in front of a sofa, or a pair used together. The geometry also carries at a distance, so a small rug in these designs reads clearly across a room in a way that a finely drawn floral of the same size often does not.

In the trade, work from this corner of the province may be offered as Afshar, under a neighboring district name such as Sirjan or Baft, or simply as Kerman, since the province name has traveled on its districts' output ever since Kerman was built up as one of the hubs supplying the European market in the nineteenth century. Knowing which name you are actually looking at matters. An Afshar-district rug is a tribal and village weaving with its own vocabulary, and it should be judged on the quality of its wool, the clarity of its drawing and the honesty of its dyes, not measured against a city rug it was never trying to be.

A Persian rug is an Iranian rug — a rug hand-knottedSee in the carpet dictionary in Iran — and the tradition behind it is the oldest documented anywhere. The earliest surviving carpet, the Pazyryk rugSee 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 dynastySee in the carpet dictionary, from 1501 to 1732, the court promoted weaving alongside painting and calligraphy, and the workshops of Tabriz, HeratSee in the carpet dictionary, Kashan and Kerman produced the masterpieces that now sit in museums. This is when the great central medallionSee 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 dynastySee 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 HerizSee in the carpet dictionary, BakhtiariSee in the carpet dictionary and KarajaSee in the carpet dictionary sit in between, mostly geometric and largely woven from memory. Tribal rugs — Baluch, TurkomanSee in the carpet dictionary, QashqaiSee 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 AbbasiSee in the carpet dictionary palmettes, flowing arabesques, the small repeating Herati patternSee in the carpet dictionary, medallions, garden and tree-of-life compositions. These combine with regional habits into styles a practiced 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: madderSee in the carpet dictionary reds, indigo blues, saffron yellows and the soft whites of undyed woolSee in the carpet dictionary, 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 batchesSee in the carpet dictionary — the effect called abrashSee in the carpet dictionary — are a mark of small-batch natural dyeing, not a flaw.

The pileSee in the carpet dictionary is almost always woolSee in the carpet dictionary, and in a Persian wool rug the wool itself decides much of the 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 yarnSee in the carpet dictionary gives a finer, softer thread than machine spinning. Fine pieces add silk highlights to a wool pile, and at the very top sits the Persian silk rug, 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 knotSee in the carpet dictionary, usual in central and eastern Iran, or the symmetric Turkish knotSee in the carpet dictionary, common in the north-west ever since Seljuk weavers introduced it in the eleventh and twelfth centuries. A large rug holds in the region of two million knots and can occupy a weaver for about a year.

Knot densitySee 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 densitySee 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 loomSee 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.
