n : a manual of black magic (for invoking spirits and demons)
A grimoire /ɡrɪmˈwɑr/ is a textbook of magic. Such books typically include instructions on how to create magical objects like talismans and amulets, how to perform magical spells, charms and divination and also how to summon or invoke supernatural entities such as angels, spirits, and demons. In many cases, the books themselves are also believed to be imbued with magical powers, though in many cultures, other sacred texts that are not grimoires, such as the Bible, have also been believed to have supernatural properties intrinsically; in this manner while all books on magic could be thought of as grimoires, not all magical books should.
While the term grimoire is originally European and many Europeans throughout history, particularly ceremonial magicians and cunning folk, have made use of grimoires, the historian Owen Davies noted that similar books can be found all across the world, ranging from Jamaica to Sumatra, and he also noted that the first grimoires could be found not only in Europe but in the Ancient Near East.
