 This suggested that a meaningless hoax manuscript as long and as apparently linguistically complex as the Voynich manuscript could be produced, complete with coloured illustrations, by a single person in between 250 and 500 hours.However, there is debate about the features of the manuscript which Rugg's suggested method was not able to emulate.The two main features are lines showing different linguistic features from the bulk of the manuscript, such as the Neal keys, and the statistical properties of the text produced.
