VMs: Re: Mediaeval book written entirely in cipher

[Nick Pelling <incoming@xxxxxxxxxxxxxxxxx>]

This direction is potentially quite amazing. Just about all the different 
threads involved are "secret histories" -- camera obscura, ciphers, 
combinatorial machines, and even the "Theatre of Memory", which Culianu 
covers in some depth in his book on Renaissance imagination.

*Well* worth pursuing! :-))))  Go for it, Phil! :-)
