Denying any responsibility for this is: The Thinker
The author writes:
It is rather a mystery as to what happened to the famous historical chronicler of the 17th Century, Sir Randolph Wren of Reading, but last month historians uncovered some previously unseen manuscripts in the man's former house. What we do know is that during the English Civil War he did his utmost to appear neutral on the outside, but deep down was an avid supporter of the Parlimentarian faction; we also know that he had a penchant for writing in various forms of code.
He went missing around 1660, during the Restoration, however going off the dates written on the papers we found, corroborated by analysis of the handwriting and the presence of a purseful of coins, these more recent manuscripts date from 1662. Slight issue, the bulk of the writing is, you guessed it, written in code, and a previously unknown form too. The museum has given me permission to republish copies of these manuscripts, so over the next eight weeks I'll be publishing a page or two at a time on this website so that you, the readers, can assist in our deciphering efforts!
Or, would you rather I just posted more comics of "Percy the Cat" again?
*sigh* The cat it is then...
