The Ars Goetia is one of the most notorious works of ritual occultism ever created. Originally part of a loose literary history dating to the 17th century, it was compiled with other material by Samuel MacGregor Mathers in 1904, forming the infamous "Lesser Keys of Solomon" or Lemegeton. Containing a list of seventy two demons, their seals, and the method by which they can be summoned by the Master, this book (for it is its own book) contains a fair mix of the bizarre along with its demonology, with grotesque descriptions of otherworldly beings constrained by King Solomon himself; those selfsame fiendish devils which, by his power, built the Temple of Jerusalem itself.
