Voynich manuscript
The Voynich manuscript was written in the 15th century in an unidentified script writing an indecipherable language. Its first recorded appearance was in Prague in the 17th century. (PROSE: Grey's Anatomy) It was known to be in the library of John Dee and was rediscovered by Wilfred Voynich in 1912.
In 1948, George Tremayne was assigned to work on the Voynich manuscript and gave a speech on a small discovery he made, that Roger Bacon had been one of the transcribers of the document in the 13th century. (PROSE: Ancient Whispers)
In the 27th century, the legitimacy of the manuscript was still debated. Cruixley said "any idiot with a Cardan grille" could have made the manuscript. He believed it was made by a prankster passing himself off as a mystic. Felix Ptarmegan Pfitch believed that Zipf's Law proves the manuscript isn't a polyalphabetic cipher. (PROSE: Grey's Anatomy)
