|Pictured: the Dungeons and Dragons theory.|
So, it remains a mystery. All anybody really knows is that an antiquarian book dealer named Wilfrid Voynich got a hold of it in 1912. (Thus, the name.) The general consensus is that the book is ~500 years old, but it could be older or younger (the hoax theory thinks it's a lot younger).
Whatever explanation there is, I think it's beautiful -- if anyone ever makes Voynich manuscript fabric, then I'd love to buy some. (If there's a Lolita skirt/dress out there, then even better!)
So what do you think, readers? Is it an almanac? Aliens? D & D? Or was it written for the noble purpose of stumping future archeologists?
