Four 19th century Aymara coca bags. These bags all have natural dyes and are in excellent condition. Coca bags were very important within Andean highland cultures going back many centuries. 19th century Aymara coca bags are exceptional and are the proud continuation of the ancient warp-faced weaing tradition of the high Andes. Coca was considered sacred to the Andean people and Aymara coca bags demonstrate this importance by the fineness and excellence of the spinning, weaving and dyeing found in these bags. Others available.
