The __Voynich Manuscript__ is an illustrated book written in an unknown alphabet in an unknown language, dubbed "Voynichese". Statistical analysis indicates patterns similar to actual languages, such as Zipf's laws, and possibly indicating that it is meaningful. For instance, in the botany section, the first word on each page occurs only on that page, and may be the name of the plant. It was apparently written by two authors who used different dialects or spelling conventions.
