The Weaver's Thread at Nevasa: Microscopic Evidence for Cotton Spinning in Chalcolithic Maharashtra

By Kavya Sharma

In the mid-1950s, during excavations led by H.D. Sankalia along the Pravara River in Ahmednagar district, Maharashtra, archaeologists unburied a series of Chalcolithic (Copper Age) burials at the site of Nevasa (Sankalia et al., 1960). Among the grave goods was a necklace of small copper beads (Sankalia et al., 1960). Deep inside the narrow perforations of those copper beads, protected from total organic decay by corrosion products, lay mineralized fragments of string (Gulati in Clutton-Brock et al., 1961).

Laboratory analysis conducted by A.N. Gulati revealed that the beads were strung on a compound thread: core strands of wild silk wrapped with a nep (clump of short fibers) of cultivated cotton (Gulati in Clutton-Brock et al., 1961).

That tiny organic residue offers crucial physical evidence for textile production in the Northern Deccan during the second millennium BCE. Evidence shows that during the Jorwe phase (roughly 1400–1000 BCE), farming communities in rural Maharashtra were not merely harvesting raw plant fibers; they were spinning, blending, and processing them into functional cordage and cloth (Chakravarti, 2016).

The Chemistry of Mineralized Fibers

Organic materials like cotton thread rarely survive thousands of years in the monsoon-drenched soils of central India. When plant fibers decay, soil microbes digest the cellulose within decades.

The preservation of the Nevasa thread relied on a chemical process called mineralization. As the copper beads oxidized over centuries, copper salts leaching from the metal penetrated the surrounding textile strands. These metallic compounds acted as a biocide, killing off bacteria and fungi before the thread could completely decompose. Microscopic examination showed that while the organic material itself broke down, copper carbonate casts precisely preserved the structural twist, diameter, and cellular features of the cotton and silk fibers (Gulati in Clutton-Brock et al., 1961).

The identification of Gossypium (cotton) fibers at Nevasa established that Chalcolithic communities possessed the technical knowledge required to process raw cotton bolls (Clutton-Brock et al., 1961). Raw cotton fibers feature a distinctive natural twist—termed convolutions—that allows them to interlock when spun under tension. Combining cotton with silk strands created a reinforced thread capable of holding metal beads, demonstrating an intentional choice of material properties by local craftspeople (Gulati in Clutton-Brock et al., 1961).

Spindles and Seeds in the Jorwe Phase

Microscopic fiber fragments are only one part of the archaeological picture. To understand how textile production fitted into daily life, archaeologists look at the broader toolkits recovered from Jorwe phase layers across Nevasa and neighboring sites like Chandoli and Inamgaon (Dhavalikar, 1988).

Excavators at Nevasa recovered numerous terracotta spindle whorls—perforated ceramic discs fitted onto wooden drop spindles to provide momentum while twisting raw fiber into yarn (Sankalia et al., 1960). The weight and diameter of these whorls directly influence the thickness of spun yarn: lighter whorls produce fine cotton threads, whereas heavier ceramic discs yield coarse cords suitable for mats or heavy garments.

Archaeobotanical soil flotation—a method of washing site sediment to recover carbonized plant remains—yielded charred seeds of Gossypium alongside crops such as barley, wheat, lentils, and flax (Kajale, 1988). While isolated fiber finds might theoretically indicate trade imports, the presence of charred cotton seeds confirms local cultivation (Kajale, 1991). Farmers were growing cotton bolls in the rich black cotton soils (regur) of the Pravara valley, ginning the seed from the fiber, and spinning yarn within their village settlements (Kajale, 1988).

Household Crafts in a Rural Economy

Scholars debate the economic organization of Chalcolithic Deccan settlements (Dhavalikar, 1984). Unlike the urbanized centers of the earlier Harappan civilization, which maintained large-scale industrial workshops, settlements like Nevasa consisted primarily of rectangular wattle-and-daub mud houses (Chakravarti, 2016).

Evidence shows that textile production at Nevasa operated as a household-level craft integrated with subsistence farming (Dhavalikar, 1988). Spindle whorls were recovered scattered across ordinary house floors rather than concentrated in centralized craft precincts (Sankalia et al., 1960). Families cultivated cotton as part of a multi-cropping strategy tailored to the semi-arid climate of Maharashtra (Kajale, 1988). Spinners spun thread during dry seasons between planting and harvest, providing household garments, cordage for stringing beads, and materials for local exchange (Gulati in Clutton-Brock et al., 1961).

The tiny thread from Nevasa demonstrates that thousands of years ago, long before the Deccan became a renowned global hub for cotton exports, rural households along the Pravara River had already mastered the micro-technologies of fiber selection, blending, and spinning (Gulati in Clutton-Brock et al., 1961).
