The Book That Can't Be Read. The Voynich Manuscript.

Countless books have been banned throughout human history. Countless people have been persecuted for what they've written, read or declared. Countless people have avoided this through symbolism and cryptography...but only one book has been found that no one on Earth has been able to decipher and still keeps it's secrets within it's glorious pages of other-worldly illustrations and depictions...Check out The Voynich Manuscript, an ancient text that has yet to be deciphered and is called by many "the most mysterious manuscript on the planet."
