Zodiograph

That these kinds of elaborate zodiographs were not used to any extent, as far as we know, in the developmental stages of any writing system is due, we suspect, to the sub fades operation of a kind of "efficiency principle."

The process of shifting from a pictograph to a zodoiograph is the process of acquiring a pronunciation. This process we call "phoneticization," and it is at this point that pictographs, or any other kind of graphs, turn into writing.

Short of pointing to the corresponding khipu cartouche, an ideograph for “corn-planting month,” say, would have to be named to be spoken of, and all that is required to produce a zodiograph is for the spoken word to stick to the conventional graphic representation.
