The Voynich Manuscript/Claude Martin
Claude Martin claims that the Voynich manuscript would contain a phoney text, based on numeric sequences transcribed into anagrams. For example, a line forged on sequence 345678 would be retranscribed into 643875. This « fill in text method » would be used to produce text having some semantic similarities with a real text.
