Hook-shaft pattern loom - the world's first pattern loom

Hook-shaft pattern loom is excavated in the Laoguanshan Han dynasty tomb, Chengdu, Sichuan Province  in 2012. At the bottom of one wooden coffin, they discovered four model looms made of wood and bamboo, along with traces of silk threads and dyes. The largest of the four looms is 50 centimeters tall, 70 centimeters long and 20 centimeters wide. The other three looms are smaller, measuring around 45 x 60 x 15 centimeters. Of equal interest were the 15 miniature painted wooden human figures which, judging from their postures and inscriptions, may be models of the workers at a workshop where Sichuan jin silk was produced. To date these are the only complete models of Han dynasty looms with a confirmed provenance.
