Lipogrammatic text

what would be the point in a long text

I can imagine reasons of magic or political-symbolic origin, e.g. Guelphs vs Ghibellines (both would have to exclude the letter G, anyway). As soon as there are examples, like the said Petrus, this is an interesting possibility which should not be excluded.

The foremost question is whether letters would be excluded from the plain text or from the cipher text. The latter is easily checked - one just needs to check whether there are any folios or paragraphs missing any of the Voynichese glyphs (rare stuff like x excluded, of course), and if so, if there is any system in arrangement of such folios or paragraphs. From the plots in the VQP I can quickly see that there hardly is a paragraph without a, o or i, and even q is quite, quite widespread.
