Lipogrammatic text

[davidjackson]

Well, I have suggested earlier in this thread that the point could possibly be, for example, Yorkist English people, perhaps in northern France during the period of English control of that region in 1415-1429, communicating with each other in a cipher which also omitted entirely certain letters in the word "Lancaster", perhaps first of all omitting "L" and "A", for example.

We have two threads going on here:

• Arguing for a lipogrammatic text that excludes words
  
• Arguing for a lipogrammatic text that excludes letters
  

The first would read "the House of ..."
The second would read "the House of ncster". Which, I suggest, is hardly a difficult code to break.
(A real medieval encrypted text would have read "the House of DoolyDally", where DoolyDally is known by sender and receiver to be Lancaster).

The first quarter of the 15th century is exactly when the nobles transitioned from French to English.. it is impossible to say whether anybody in any position to be worried about who was reading their diaries would be written in Anglo-French or Norman
French at that time.

Anyway, back to my basic question that I always ask - if the whole thing is written in an unknown alphabet, why bother obfuscating the plain text?
