Woven air, running water, evening dew

Mughal courtiers had poetic names for the best Bengal muslins: abi-rawan, flowing water; baft-hawa, woven air; shabnam, evening dew ⁷. The finest grade of all, malmal khas or malmal shahi, was reserved for the emperor, and a court official, the Darogah-i-Malbus Khas, supervised the weavers who made it ⁵. A single piece could take up to six months on the loom ⁵.

The numbers explain the names. Most muslin sold today has 40 to 80 threads per square inch. Historical Dhaka muslin ran from about 800 to 1,200 ⁴. Banglapedia lists more than a dozen named varieties, from jhuna and tanzib to the patterned jamdani, each with its own weight and use ⁵.

A cotton that grew only by one river

The secret began in the field. The finest muslin was spun from phuti karpas, a cotton grown on the banks of the Brahmaputra and its branches in eastern Bengal ⁵⁸. Its fibres were short and difficult to machine-spin, but in skilled hands they could be drawn into an extraordinarily fine thread.

The spinning was done mostly by young women using a light spindle, the takua, often in the early morning or late afternoon on riverbanks or moored boats, where the humid air stopped the thread from snapping ⁸. The cotton then passed from cleaners to spinners to weavers, usually within a family or a group of two or three families working together ⁵. Making the cloth took sixteen separate steps ⁴. Weaving centres clustered around Dhaka: Sonargaon, Dhamrai, Teetbady, Junglebary and Bajitpur ⁵.

From the Periplus to the Mughal court

Bengal cottons appear in the earliest records of the Indian Ocean trade. The Periplus of the Erythraean Sea, a Greek merchant's guide of the 1st century CE, describes Indian cloth, muslin among it, traded at Red Sea ports for ivory and tortoiseshell, and Ptolemy's Geography mentions Bengal fabrics too ⁵⁷. Roman writers such as Petronius already called such cloth woven air ⁸.

Dhaka itself rose much later. When it became the Mughal provincial capital in the 17th century, imperial and noble patronage turned its muslin into a court luxury, and the trade flourished under Jahangir ⁵⁸. In 1747 Dhaka's cotton exports were valued at 28.5 lakh rupees ⁵. By the 1700s muslin had spread to Persia, Turkey and Europe, where it dressed Marie Antoinette and the heroines of Jane Austen's novels ⁴.

How the finest cloth on earth disappeared

After the Battle of Plassey in 1757 the English East India Company took control of Bengal, and the trade began to fall apart ⁵⁷. Mughal and nawab patronage vanished, the Company monopolised purchasing and pushed weavers into debt with ever lower prices, and cheap machine-made British cloth flooded the market ⁴⁵. Famines and floods added to the damage ⁷. Dhaka's exports had halved by the end of the 18th century and were worth under 10 lakh rupees by the mid-19th ⁵.

Dhaka muslin was still admired at the Great Exhibition in London in 1851 ⁵, but by then it was a relic. The phuti karpas plant itself is believed to have died out, and no seeds are known to survive ⁴⁸. The V&A still holds a jamdani muslin sari woven in Dhaka around 1855, one of the last pieces of the old industry to reach a museum ⁶.

Bringing it back from a dried leaf

Two projects in Bangladesh are now trying to recover the cloth. Bengal Muslin, launched in 2014 by the Drik photography agency under Saiful Islam, found a booklet of dried phuti karpas leaves at the Royal Botanic Gardens, Kew, sequenced their DNA and located a wild shrub in Bangladesh that was a close match ⁴. A separate government-backed effort led by the botanist Md Monzur Hossain at Rajshahi University has produced six saris ⁴.

Neither has yet grown enough of the cotton for a pure garment; Bengal Muslin blends it with other cotton into a hybrid yarn, and its saris have sold for thousands of pounds ⁴. The surviving patterned form, jamdani, has never died out, and has been recognised by UNESCO as intangible cultural heritage ⁸.

Background

Cotton grown along the Brahmaputra and Meghna in eastern Bengal, a short-stapled variety called phuti karpas, could be hand-spun into yarn finer than any machine of the time could manage. Bengali spinners and weavers turned it into muslins so light that Mughal courtiers named them woven air and running water, and Dhaka, Sonargaon and Dhamrai became the centres of a trade that reached Rome in the first century CE and Europe again in the eighteenth.

Significance

Dhaka muslin was for centuries the finest cloth anyone could buy, with thread counts that modern hand weaving has struggled to match. Its collapse under East India Company rule and British factory competition made it a lasting symbol of what colonial trade did to Indian craft industries.

Meanwhile in the West

European industrial textiles came much later (and undercut the craft).

Fair to say

The finest weaves and the specific cotton variety were later lost.

Path to modern innovation

A pinnacle of hand-textile technology.
