A short note by T. A. Joyce describing a miniature pre-Spanish Peruvian loom of the Chimu period in the British Museum, with its dimensions and construction. The loom is set up for double-faced cloth with two warps and two wefts, white and brown cotton, and has two heddle rods and a reed shed-stick. Joyce describes the continuous warping, the twined selvage, the cat-and-stepped-coil design, and the thread counts. He compares the heddle-leash arrangement with looms elsewhere and dates the piece to after about 1400 A.D. and before the Spanish arrival.
