Voynich manuscript

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), glossolalia[19] or work of fiction (e.g. science fantasy or mythopoeia, metafiction, speculative fiction).

Isn't it obvious?

You should've blurred the pic, since that text definitely is not safe for work!
