If you’re searching for a Halloween costume, you may want to dive back in time. What’s more frightening than creepy demons from the 18th century? If a compendium of demonology is any indication, absolutely nothing. The Public Domain Review gathered together some of the most monstrous images from Compendium rarissimum totius Artis Magicae sistematisatae per celeberrimos Artis hujus Magistros or, in English, A rare summary of the entire Magical Art by the most famous Masters of this Art.

Written in German and Latin, the 1775 book is clearly designed to fool readers into thinking it’s an older text, since the title page declares that it’s from 1057. The demons inside are timelessly creepy, though, and it’s a collection that’s sure to provide you with some scary inspiration. Check out a few of our favorites, like this buff and jaunty intellectual goat (?) demon and his freaky pals:
