Goetia is a type of European sorcery, often referred to as witchcraft, that has been transmitted through grimoires—books containing instructions for performing magical practices. The term "goetia" finds its origins in the Greek word "goes", which originally denoted diviners, magicians, healers, and seers. Initially, it held a connotation of low magic, implying fraudulent or deceptive mageia as opposed to theurgy, which was regarded as divine magic. Grimoires, also known as "books of spells" or "spellbooks," serve as instructional manuals for various magical endeavors. They cover crafting magical objects, casting spells, performing divination, and summoning supernatural entities like angels, spirits, deities, and demons. Although the term "grimoire" originates from Europe, similar magical texts have been found in diverse cultures across the world.

Hermeticism or Hermetism is a philosophical and religious system based on the purported teachings of Hermes Trismegistus. These teachings are contained in the various writings attributed to Hermes, which were produced over a period spanning many centuries and may be very different in content and scope.
