But I’ll draw your attention to something slightly different:
1). You mean that the encryption scheme is very complex, but it will be complex if you want to encrypt a book very quickly. You won’t be able to write a 200‑page book in a week, even in unencrypted form. Why couldn’t the author simply come in the evenings, take the parchment, and gradually encrypt the text? Moreover, if one person was doing the encrypting (and I don’t think that’s the case), they could have done it in a fairly measured and lengthy manner. And in their old age, let our beloved “silly scribes” copy their drafts onto parchment.
This is regarding the encryption.
2). VMS is hardly some kind of fairy tale. It’s unlikely that the text spanning 200 pages is coherent. The maximum is Quire 13 and Pharma, where the text is clearly connected in terms of meaning, but only within the section. That is, if you need to extract some information from this book, you can use the key to open a couple of the necessary pages and decipher them. If the difficulty for you lies in the number of pages, then there isn’t any here. In Quire 13 there are 20 pages. I don’t think that even if it were a book cipher, it would be that difficult.
This is regarding the decryption.
Of course, these are all assumptions, and I can’t prove it... But at the very least, this is a reminder that sometimes you need to doubt. Even your own words
