Um manuscrito curioso - the «Voynich manuscript»:
«The Voynich manuscript is an illustrated codex, hand-written in an unknown script referred to as Voynichese.[18] The vellum on which it is written has been carbon-dated to the early 15th century (1404–1438). Stylistic analysis has indicated the manuscript may have been composed in Italy during the Italian Renaissance.[1][2] While the origins, authorship, and purpose of the manuscript are still debated, hypotheses range from a script for a natural language or constructed language, an unread code, cypher, or other form of cryptography, or perhaps a hoax, reference work (i.e. folkloric index or compendium), or work of fiction (e.g. science fantasy or mythopoeia, metafiction, speculative fiction) currently lacking the translation(s) and context needed to both properly entertain or eliminate any of these possibilities.
The manuscript is named after Wilfrid Voynich, a Polish book dealer who purchased it in 1912.[19] The manuscript consists of around 240 pages, but there is evidence that pages are missing. The text is written from left to right, and some pages are foldable sheets of varying sizes. Most of the pages have fantastical illustrations and diagrams, some crudely coloured, with sections of the manuscript showing people, fictitious plants, astrological symbols, etc. Since 1969, it has been held in Yale University's Beinecke Rare Book and Manuscript Library.[20][12][21] In 2020, Yale University published the manuscript online in its entirety in their digital library.[22]
The Voynich manuscript has been studied by both professional and amateur cryptographers, including American and British codebreakers from both World War I and World War II.[23] Codebreakers Prescott Currier [d], William Friedman, Elizebeth Friedman, and John Tiltman were unsuccessful.[24]
The manuscript has never been demonstrably deciphered, and none of the proposed hypotheses have been independently verified.[25] The mystery of its meaning and origin has excited speculation and provoked study.»
