Isfahan · Persian carpets
On Persian Rugs
Isfahan, Iran
I grew up in Iran and trained as an architect there. Long before I could draw a plan, I understood what it meant for a room to have a carpet in it — that the floor was where a household actually lived, and that the thing covering it was not decoration but structure.
Isfahan
A city that organised itself around a square
Shah Abbas I moved the Safavid capital to Isfahan in 1598 and rebuilt it around Naqsh-e Jahan, a square so large it was laid out for polo. The mosques, the palace and the entrance to the bazaar all address it. UNESCO inscribed it as a World Heritage Site in 1979, and it remains one of the most complete pieces of urban design anywhere.
That century is also when Persian carpet weaving reached the height of its ambition. Court workshops in Isfahan, Kashan and Tabriz produced carpets as considered as the buildings around them — the same vocabulary of arabesque, palmette and medallion, worked in wool and silk rather than tile.
It matters to me as an architect that these were never separate disciplines. The person setting out a carpet's medallion and the person setting out a courtyard were solving a related problem: how a centre holds a field, and how a border tells you where the field ends.
The bazaar
Where a carpet is still unrolled in front of you
The Grand Bazaar of Isfahan runs from the square under vaulted brick, and parts of it are far older than the Safavid city built around it. Carpets are still sold there the way they have always been sold: pulled from a stack, thrown open on the floor, and looked at while tea arrives.
That ritual is not theatre. A carpet cannot be judged folded, or in a photograph, or under a single light. It has to be seen flat, from both ends — the pile runs one way, so a rug read against the nap is a different colour from the same rug read along it. Sellers know which end to show you first.
Reading a rug
What I look at, in order
Most of what tells you whether a carpet is hand-made, and roughly what it is, can be established in a few minutes without instruments. None of it requires taking anyone's word.
- 01
Turn it over first
On a hand-knotted rug the design reads clearly on the back, knot by knot, because the knots are the rug. A machine-made rug shows a regular grid, often with a stiff backing or latex glue, and the pattern is blurred or absent underneath.
- 02
The fringe should be the rug
Fringes are the warp threads the rug was woven on, emerging at the ends. If the fringe is sewn or glued on as a separate strip, the rug was made by machine. This single check settles a surprising number of questions.
- 03
Knot type and count
Persian weaving generally uses the asymmetric knot, Anatolian and Caucasian the symmetric one. Count knots across an inch on the back in both directions. Fine Isfahan work runs very high; a low count is not automatically bad, but it should match what is being claimed and charged.
- 04
Look for abrash
Abrash is a soft horizontal shift in colour where the weaver moved to a new dye lot. It is evidence of hand-dyed yarn and hand weaving, not a defect — and it is one of the harder things to fake convincingly.
- 05
Test the colour, gently
Natural dyes age unevenly and usually lighten toward the tip of the pile. Press a damp white cloth firmly into the pile: significant colour transfer suggests a fugitive synthetic dye or a rug that has been over-dyed to hide wear or fading.
- 06
Feel the wool
Hand-spun wool varies slightly in thickness along its length and keeps enough lanolin to feel supple, with a low sheen that grows with use. Wool that feels dry, squeaky or brittle has usually been over-washed or stripped.
- 07
Trust the irregularities
Motifs that vary slightly across a field, borders that do not quite resolve at the corners, a rug that is a centimetre wider at one end — these are the fingerprints of a person at a loom. Perfect symmetry throughout is a warning, not a reassurance.
- 08
Treat silk claims sceptically
Mercerised cotton and viscose are routinely sold as silk. Real silk is warm to the touch, extremely strong, and lacks the cold, over-bright lustre of viscose — which also crushes and greys where it is walked on. Where the price turns on the answer, ask for it in writing.
- 09
Signatures prove less than people think
Isfahan's best-known workshops sign their work in a cartouche, and those signatures are among the most copied things in the trade. A signature is a claim to be checked against the weaving, not a substitute for checking it.
None of this makes me an appraiser. Anything that turns on a number — insurance, probate, resale — should go to a qualified valuer. What it does let me do is tell a client, honestly, whether the rug in front of them is what the label says it is.
In the work
The largest textile decision in the room
In a finished interior a carpet is doing more work than anything else soft in the room. It sets the acoustic — a hard-floored room with no rug is a room people raise their voices in. It fixes the circulation, because furniture placed off a rug never quite looks placed. And it carries more colour, across more square footage, than any other single specification.
So I would rather start from a rug than arrive at one. If a client already owns a good carpet, it is usually the most interesting constraint in the project, and the palette is better for being answerable to it. Buying one last, to fill a gap in a scheme that is already resolved, is how rooms end up with an expensive object nobody looks at.
The other reason is durability. A well-made carpet on a good foundation will outlast every other thing bought for the room, including the sofa and probably the house's current owners. Very little else specified for an interior can be said to improve for the next hundred years.
