In movies about witchcraft and sorcery, those who deal in black magic always rely on creepy spell books. But as it turns out, these seemingly fictional books actually exist in real life.
Clavis Inferni is a Scandanavian book of twisted magic, and it's also known in occultist communities as the Black Book. It is said that the book was studied by pupils of the Black School at Wittenburg -- a school in Germany dedicated to the practice of dark arts, and only they could decipher its strange script, which is a combination of Latin, Hebrew, and Agrippa's magic alphabet.
The author of this book is listed as Cyprianus, which is a name that many occult writers have adopted over the centuries.

The black books, grimoires, and books of spells are historically forbidden by Christian leaders to be read by practitioners. It is believed that reading these books all the way through invites the Devil into your home. But as reviled as they are, they are equally as championed in weird pockets of the Internet. Occultists still gather to this day.
