The Incan talking knots — knotted cords carrying records and messages; cord color is identity, pendant cords gather voices into one telling.
Quechua khipu (knot), borrowed into Spanish and English as quipu/quipus; the Incan recording system knotted cords of different colours into records and messages, with colour and position carrying meaning the way ink and layout do on a page.
The Incan talking knots — cords carrying records and messages by colour and by where each knot sits. A telling made of touch rather than ink, and no less a form of writing for that.
