The fifteenth-century Voynich Manuscript has been deemed “the most mysterious manuscript in the world.”
It’s written in a code that even World War I and World War II codebreakers can’t break, and it doesn’t seem to have any chapters or subheadings. The only reason people think they know what the book is about is because nearly all of the Voynich’s 246 pages are illustrated; pictures include botanical diagrams (some of planets that don’t seem to exist), astronomical figures, and drawings of naked ladies in rivers.
My theory? It’s a gift from our friends, the Ancient Aliens.
