Description

Quipu, or string abacus. Five thin strands of twisted wool fibre are tied to a loop of similar construction. The cords each carry a series of knots, used as a counting or record keeping system. One holds a separate strand, tied near the top. Strands are coloured blue-grey, blue and tan, a mix of brown and tan, brown, and two are completely tan. The loop is light tan and grey-blue.
