They aided in data collection and book - keeping , admit the monitoring of revenue enhancement obligations , census records , calendric information , and military organization . The electric cord hold numeric and other value encoded on grayback in a base-10 positional system . Some quipu had as many as 2,000 cords .

The Khipu Database Projectdescribes quipu and how they run :

Most of the exist khipu are from the Inka geological period , approx 1400 – 1532 CE .

The word khipu comes from the Quechua word for “ gnarl ” and denote both singular and plural . Khipu are textile artifacts composed of corduroys of cotton or once in a while camelid fiber . The cords are arranged such that there is one main cord , called a primary cord , from which many pendant cords hang . There may be additional cords attached to a pendent cord ; these are termed subordinate . Some khipu have up to 10 or 12 grade of subsidiaries . Khipu are often display with the primary cord stretched horizontally , so that the pendants appear to mold a curtain of parallel electric cord , or with the master electric cord in a curve , so that the pendants radiate out from their full point of attachment . When khipu were in use , they were enthrall and store with the chief cord rolled into a spiral . In this configuration khipu have been compared to drawstring mop .

Each khipu corduroy may have one or many knot . Leland Locke was the first to show that the knots had numeric signification . The Inkas used a decimal system of counting . number of varying magnitude could be indicated by mile type and the position of the gnarl on its cord . begin in the 1970 ’s , Marcia and Robert Ascher conduct invaluable research into the numeric significance of khipu , and developed a system of record khipu detail which is still in wide usance today among khipu researchers . More recently , researchers such as Gary Urton have recognized the depth of information hold back in non - numeric , structural constituent of khipu .

Regrettably , many of these quipu were destroy by the Spanish conquistador in the 16th century , do this late find all the more precious .
