Ah, so you mean a Vigenère-type cipher. I though @JoJo was referring to a codebook-style cypher, namely a substitution cipher operating on words instead of characters. Even if the codebook is used once and then lost or discarded, if the text is long enough...
I think that a Vigenère-type cipher is rather unlikely because it would "homogenize" the word frequencies -- instead of a "most common word" there would be multiple equally common "most common words", etc. So it would have to be someting even more complicated than a simple Vigenère. Seems rather unlikely for the times...
All the best, --stolfi
