The Book of the Sacred Magic of Abra-Melin the Mage is a book that’s origin is debated. Some believe it is from the 15th century, where as some believe it is from the 18th century. Abramelin magic is a form of ceremonial magic using large magic squares and arrangements of letters to represent the wishes of the practitioner.
Although connected to ceremonial magic, it gets rid of much of the tools and complicated ritual involved. It also has heavily influenced the likes of Aleister Crowley and MacGregor Mathers.
