The 10 most frightening unsolved mysteries in history (With Pictures)

7. Voynich Manuscript

In the 1600s, a man in Prague named Georgius Barschius wrote to his buddy Athanasius Kircher who lived in Rome, sending a book with the letter of intricate pictures and strange text. He asked his friend to help translate it, but it was not in a language either could understand. So Kircher asked around, and eventually, linguists and historians came from all over the help discern what was written in the book. It has flowers, plants, recipes, star charts, and other illustrations, which are all of real plants and cosmic events, but the writing is not in a language anyone can understand. 400 years later, we still obsess over the manuscript, and it is still really creepy. How can a whole written language just disappear?
