The deep history of weaving is attested by spindle whorls and loom weights, so the evolution of techniques may be tracked through changes in these durable artefacts; however, wooden looms rarely preserve. Here, the authors document a series of loom weights and associated charred timbers and fibres that represent the remains of a Bronze Age warp-weighted loom, uncovered at the settlement of Cabezo Redondo in south-eastern Spain. Based on the number, weight and size of the weights, hypothetical reconstructions of loom setup and resultant textile products are proposed, revealing possible diversification of weaving processes in the mid-second millennium BC.
