Nope -- or, at least, according to some Andean paleolinguist I was chatting up at a conference 18 months ago in Chile, the field of quipu studies is now evenly split. The older version is that quipu were purely tax records, so that they recorded mostly who gave how many potatoes to whom, when, and where they ended up. A newer interpretation suggests that they may have started out that way, but later developed into a form capable of containing more complex narratives. He offered a lot of evidence for the newer view, but the only one I really understood was that for almost 70 years, archeologists (et al) argued the same thing about Maya glyphs -- that they were only calendrical and numeric.

I saw a huge exhibit of them in Santiago; they're truly beautiful and full of details that might or might not signify (variations in distances between knots, color of thread, thickness of thread, type of knots, how many threads are attached to each other in what configurations.) A great puzzle.

Had you heard, too, that somewhere in inland lowland Yucatan there's a stele containing some Mayan prince's proad boast that he ate a lot of fresh seafood? In the Late Classic as now, I guess, fine dining was a status marker.
