If you thought James Joyce’s Ulysses was difficult to understand, take a gander at the legendary “Voynich Manuscript.”

The 240-page book is housed in Yale’s Beinecke Rare Book and Manuscript Library and has been carbon-dated to roughly 1420. It’s full of bizarre handwriting and cryptic drawings—that look like the scribblings of a productive person on LSD.

And the biggest mystery of all? Experts can’t decipher what any of it means or says. Find out more about the manuscript in the TED-Ed video above.
