Good catch, nice read, with a computational angle.
Take a walk down some of the older lanes in London, say near Borough Market or back up towards Southwark, or the other side between Brick Lane and Petticoat Lane, and imagine yourself back in the 1700s.
Coffee houses, close groups having meetings, private rooms upstairs in narrow houses. The feeling that true knowledge was being passed on. The meaning people found in the processes of the primitive technology.
It strikes me that the boring bits of the decoding (tokenising the symbols, entering the tokens) could be farmed out using a web site hosting scans of texts. The computational resource could perhaps be spare cycles on a PC with an appropriate application. Scope for lay science of a particularly interesting kind, and the refinement of algorithms as they are applied to a larger corpus of texts.
