Why would he even try to use Latin if the rest of the book is Voynichese?

Because he did not know Voynichese, not even the alphabet.  Not even enough to know that there were no Latin letters in it.

He may have been an owner who acquired the manuscript out of impulse or by inheritance, looked at the figures for a day or two, and never bothered to study the text -- "just some weird writing".

He could be a librarian scrambling to save a pile of books from damage by a storm and a leaking roof.

He could be a friend of the owner, who borrowed the book out of curiosity, promptly spilled his beer over it, wiped it off, and then clumsily tried to undo the damage.

Anyway, he did not know Voynichese, so when he looked at the few bits of writing that had survived his guesses could only be Latin letters.  And since some looked like crosses, he guessed that it must have been a charm...

All the best, --stolfi
