[split] The Zipf law and the Voynich Manuscript

[Torsten]

That the main text obeys Zipf's law and the labels do not is not going to be easy to explain if you think it's something other than a meaningful text.  Maybe someone in the early 15th century had already discovered Zipf's law and consciously created a nonsense text to emulate these properties?

Actually, the Zipf's law does not prove meaningful text at all. Please have a look at this paper: You are not allowed to view links. Register or Login to view.

Indeed, Zipf's law describes the distribution of numbers measuring a complex system. For instances firm sizes fit to Zipf's law [see  You are not allowed to view links. Register or Login to view.].

What Zipf's law tells us is that in some way the text generation mechanism for the labels is less complex. The observation that more unique and rare words are used as labels allow a similar conclusion [see You are not allowed to view links. Register or Login to view.].
