How many Sundays did we spend doing the cryptograms and crosswords in the newspaper?
Dan Brown -- The Da Vinci Code
P. O. Dolphin’s Barn: the transliterated name and address of the addresser of the 3 letters in reversed alphabetic boustrophedonic punctated quadrilinear cryptogram (vowels suppressed) N. IGS.
James Joyce -- Ulysses
…the whole point of his "Current Shorthand" is that it can express every sound in the language perfectly, vowels as well as consonants, and that your hand has to make no stroke except the easy and current ones with which you write m, n, and u, l, p, and q, scribbling them at whatever angle comes easiest to you, his unfortunate determination to make this remarkable and quite legible script serve also as a Shorthand reduced it in his own practice to the most inscrutable of cryptograms.
George Bernard Shaw -- Pygmalion
A common form of Jewish cryptogram, the Atbash Cipher was a simple substitution code based on the twenty-two-letter Hebrew alphabet.
