There is something called Enochian Magick, based off the Book of Enoch. I've looked into it before, though never did much with it. There are articles here on SoM that talk a bit about Enochian Magick, as well as some forum posts. Use the search bar in the top right hand corner if you want to read about it.
The Book of Enoch itself is interesting- but that's about it. If you've never read it before, perhaps take the time to.
