Narrative threads  

Apostropher links to this fascinating story (also here) about Incan Khipus and the strong possibility that they may be a form of recorded language, not written, but woven and knotted. This is of great interest to me beacuse of my nascent study of Aymara - it looks like many of these khipu are found among the Aymara, which may be provocative. I'll be investigating this further - for one thing there's a book at Amazon, although maybe it's a little dated?
