To me, cracking the Jagged Edged cipher is about spotting patterns. The Jagged Edged cipher is what I call it. I’ve no idea what, if anything, it’s actually called.
I realise it must be a Freemason cipher ; and no I’m not a Freemason. The earliest example, that I’ve found so far, is the Introduction written by Ben Jonson to William Shakespeare’s First Folio (1623). It involves no deaths, whatsoever, just very clever word play.
I suspect the origins of The Jagged Edged cipher go back perhaps as much as a 150 years earlier ; in texts of 1460s / 1470s in the Florentine dialect of Italian.
Along the way, I’ve found the Jagged Edged cipher, without any deaths, whatsoever, in these poems in English:
Ozymandias (Percy Shelley) 1818
The Charge of the Light Brigade (Alfred Tennyson) 1854
Invictus (William Ernest Henley) 1875
I’ve also found The Jagged Edged cipher has been used in the disappearance of people who later reappeared alive:
Michelle Knight / Georgina DeJesus / Amanda Berry
An as yet unsolved case of a 17 year (juvenile) British girl who’s been a Missing Person for several years. Based upon the Kampusch and Knight / DeJesus / Berry cases I think that it’s possible that the British youngster could still be alive. But, I don’t know that as a fact only as a decryption of the Jagged Edged cipher. Recently I read in the national newspapers that a police force says that she’s not alive.
My interest in The Jagged Edged cipher isn’t about death rather the challenge of cracking a cipher that some smart Alecs think is unique.
