Heap's Law

[Anton]

For example - the stars are not stars, but symbols of flowers.

This is my long term suspicion - that labels are not "labels", in the sense that they are not "identifiers". What would be the cause for this - either the deliberate intention to avoid giving out clues for decryption, or perhaps some intrinsic limitations of the "encoding" process, - is not quite clear.

What is obvious though is that, say, if stars labels are not identifiers then, - considering that for practical purposes the reader would need some means of identifying them, - the charts must follow some well-known visual pattern (well-known at the time of writing, of course). If the plants Ids' are conveyed by mnemonics, then for "stars" diagrams (whether they in fact are stars, stones or otherwise) the only means of identifying them would be each star's position on a well-known diagram.
