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.

Witchcraft, as most commonly understood in both historical and present-day communities, is the use of alleged supernatural powers of magic. A witch is a practitioner of witchcraft. Traditionally, "witchcraft" means the use of magic or supernatural powers to inflict harm or misfortune on others, and this remains the most common and widespread meaning. According to Encyclopedia Britannica, "Witchcraft thus defined exists more in the imagination of contemporaries than in any objective reality. Yet this stereotype has a long history and has constituted for many cultures a viable explanation of evil in the world". The belief in witchcraft has been found in a great number of societies worldwide. Anthropologists have applied the English term "witchcraft" to similar beliefs in occult practices in many different cultures, and societies that have adopted the English language have often internalised the term.
