Voynich Manuscript

 Voynich Manuscript is a hand written and illustrated codex in a language that is not known to this day. The carbon dating performed on the manuscript put it in the early 1400s. Until recently some scholars claimed that it was all gibberish, but this year (2013) scientists from England and Argentina published a paper documenting their identification of a semantic pattern in the writing, suggesting that it is a coded message still yet to be decoded.
