Quipus in the colonial Andes

Knotted-cord records did not stop at the conquest. Acosta's 1590 Seville printing says the quipocamayos were bound to render account like public notaries and had to be given entire credit; he saw Indians produce knotted accounts at a corregidor's residencia as "testigos y escritura cierta", and a woman carry her confession on a bundle of threads. Garcilaso, who checked curacas' tribute against their knots as a boy, is also the witness who calls the system perishable.
