What a Heriz is.
Heriz is a town about seventy kilometres east of Tabriz, in the East Azerbaijan province of north-west Iran, and it gives its name to the rugs woven across the surrounding villages. Where a Tabriz is drawn from a precise gridded cartoon by a workshop designer, a Heriz is drawn from memory and from a village stencil. The two towns sit within a morning of each other and produce almost opposite rugs.
You know a Heriz by its geometry. The field carries one oversized angular medallion, stepped rather than curved, with bold blocky corner spandrels and large palmettes drawn in straight lines. The palette is earthy and sun-baked: madder rust and terracotta for the field, indigo navy for the border, walnut brown, and undyed ivory for the corners. Where a workshop rug aims for exactness, a Heriz aims for presence. Nothing about it is delicate, and that is the point.
Almost every Heriz you will meet is a large rug. The villages wove at room and palace scale for the American export market - nine by twelve, ten by fourteen, and up - because that is what the market wanted for dining rooms and drawing rooms. Scatter-size Heriz pieces exist but are uncommon. For the full atlas entry, the knot-count figures, the border vocabulary, and the identification checklist, see the Heriz knowledge page, which sits alongside the rest of the Persian rug types.
Heriz, Serapi, Bakshaish - the distinction the trade blurs.
This is where most Heriz confusion lives, and it is worth being precise, because the names carry very different prices. The first thing to understand is that Serapi is not a place. There is no town of Serapi weaving Serapi rugs. It is a trade name, applied in the Western market to the earlier and finer rugs of the Heriz district, broadly those woven before about 1900.
What earns the name is the drawing. A Serapi breathes. The medallion is smaller in proportion to the field, there is more open ground around it, the palette is softer and more atmospheric - dusty rose, sage, apricot rather than full rust - and the wool is finer. A later Heriz fills more of the field, draws bolder and heavier, and runs to a stronger, more saturated red. Set the two side by side and the difference is obvious. Read a listing without the rug in front of you and it is not, which is precisely why the Serapi label gets applied generously.
Bakshaish is a genuine village, in the same district, and its rugs are the loosest and most individual of the group. A Bakshaish medallion may be abstracted, asymmetrical, or set off-centre, and the field commonly shows strong abrash - the horizontal banding that appears where a weaver changed dye lots mid-rug. In a workshop piece that would be a flaw. In a Bakshaish it is the appeal, and collectors pay for it.
For the owner, the practical consequence is this: all three are village weaving on a heavy cotton foundation with the same mountain wool, so all three are cleaned and repaired the same way. The distinction matters for what the rug is worth and for how carefully a restorer should tread, not for the method. An early Serapi with soft vegetable dyes wants a gentler wash than a robust mid-century Heriz, and that call is made piece by piece at inspection.
Why a Heriz outlasts everything around it.
Three decisions compound into the toughest rug in the Persian tradition. The first is the wool. Heriz flocks graze the slopes of Mt. Sabalan, and the fleece they carry is unusually dense and high in lanolin. Lanolin is what gives the pile its faint sheen, and it is also a natural soil repellent - dirt sits on the fibre rather than binding into it, which is a large part of why these rugs clean up so well after decades of use.
The second is the knot count, and it runs counter to instinct. A Heriz is knotted at roughly sixty to a hundred and twenty knots per square inch, which is coarse by Persian standards and a fraction of a fine Tabriz. Owners sometimes read that as a lesser rug. It is the opposite of a weakness here: a lower knot count means each individual knot is larger and holds more wool, so there is simply more fibre standing between a shoe and the foundation. Fineness buys detail. Coarseness buys years.
The third is the structure. The foundation is heavy cotton warp with wool weft, considerably more substantial than a workshop rug's, and the edges are finished with thick hand-wrapped wool selvedges built to carry load. A Heriz holds its rectangle, lies flat, and resists the curling and rippling that plague lighter rugs under furniture. It was woven as a floor rather than as an object, and it behaves like one.
What a century of foot traffic actually does.
Durable is not the same as immortal, and because a Heriz genuinely does stay in service for generations, most of the ones we see have accumulated real wear. It arrives in a predictable order, and knowing the order tells you where to look on your own rug.
The selvedges go first. The wool wrapping along the two long edges takes the load every time the rug is walked across, vacuumed, or shifted under a chair leg, and it frays away strand by strand. That matters more than it looks: the selvedge is what holds the outermost warps in place, and once it is gone the rug has an open edge that will begin to unravel inward. A frayed selvedge caught this year is a modest repair. The same rug three years on can be losing pile into the border.
The ends go second. Fringe is not decoration - it is the warp threads of the rug itself, extending past the last row of weft. As the securing rows loosen, the fringe pulls away and takes the end of the rug with it, row by row. And third comes the pile itself, along whatever line the household actually walks: from a doorway to a chair, around the end of a dining table. The pile thins there first, and in the worst cases wears down far enough to show the pale cotton warp beneath, which is what the photograph above shows.
There is also the damage that is not from feet. Thick, dark, undisturbed wool under a heavy sideboard is exactly what clothes moths look for, and a Heriz pile is ideal habitat - see identifying and treating moth damage. And sun through a south-facing window will soften the madder reds over years, unevenly, in the shape of the light.
How a Heriz is washed.
By hand, off the floor, in cool water, with every colour dye-tested before any water touches the rug. A Heriz takes a proper hand-wash better than almost any rug we handle - the wool is robust and the foundation is heavy - but it is still natural fibre with madder and indigo dyes, and it must never be steam cleaned or run through a machine. Heat felts the pile and takes the lanolin sheen with it, swells the cotton warp, and can move the reds into the ivory corners. The same reasoning as steam cleaning a Persian rug applies here in full.
The stage that matters most on a Heriz is the one nobody sees. Before any water, the dry grit is dusted out from the back, and on a room-size village rug that has held a dining table for forty years the quantity is genuinely startling. That grit is abrasive; every step grinds it against the base of the wool. Dusting a Heriz thoroughly does more for its remaining life than anything else in the process.
Then the wash itself: soap matched to the fibre, cool temperature-controlled water, flushing the soil out rather than driving it in, and a thorough rinse so nothing is left to attract dirt back. The rug dries flat with air moving on both faces, over days. What comes back is a Heriz with its rust returned to depth, its navy separated cleanly from its ivory, and the lanolin sheen visible again. Between washes the rug wants very little: gentle regular vacuuming with the beater bar off, and a hundred-and-eighty-degree rotation once a year so sun and traffic age it evenly. Our full method is set out on the Persian rug cleaning service.
What restoration can bring back.
A Heriz is one of the most rewarding rugs to restore, because the structure underneath is usually sound long after the surface looks tired. Each of the three wear patterns has a hand remedy. Frayed selvedges are re-wrapped along the edge in wool matched to the original colour, which stops the unravelling and restores the rug's straight edge. Loose ends are secured and the lost weft rows rewoven so the fringe is anchored in the rug again rather than hanging off it.
Worn pile is reknotted. New wool, dyed to match the surrounding field as it looks now rather than as it looked in 1910, is tied knot by knot into the bare area on the original foundation and then sheared to the height of the pile around it. Done properly on a Heriz the repair is genuinely difficult to find, because the coarser village knotting is more forgiving of a hand-matched join than a fine workshop weave would be. This is the work described on the rug repair and oriental rug restoration pages.
Where sun has taken the colour rather than the wool, colour restoration rebuilds the depth with light-fast dyes matched to the rug as it stands. The judgement in all of this is knowing when to stop. An antique Heriz should look its age; the goal is a rug that is structurally sound and honestly worn, not one pretending to be new. Every piece is inspected by hand before any work begins, and we tell you plainly what a wash alone will recover, what needs the loom, and what is better left as the record of a century of use.
