Leonell C Strong a cancer research scientist and amateur cryptographer, believed that the solution to the Voynich manuscript was a "peculiar double system of arithmetical progressions of a multiple alphabet". Strong claimed that the plaintext revealed the Voynich manuscript to be written by the 16th-century English author Anthony Ascham, whose works include 'A Little Herbal', published in 1550. Although the Voynich manuscript does contain sections resembling 'A Little Herbal', the main argument against this theory is that it is unknown where Ascham would have obtained such literary and cryptographic knowledge.
