the people—even if the orthodox establishment opposes it. In some definitions, witches differ from sorceresses in that they do not need to use tools or actions to curse; their maleficium is believed to flow from some intangible inner quality, may be unaware of being a witch, or may have been convinced of their nature by the suggestion of others. This definition was pioneered in 1937 in a study of central African magical beliefs by E. E. Evans-Pritchard, who cautioned that it might not match English usage. Historians have found this definition difficult to apply to European witchcraft, where witches were believed to use physical techniques, as well as some who were believed to cause harm by thought alone. Spell casting Probably the best-known characteristic of a witch is her ability to cast a spell—a set of words, a formula or verse, a ritual, or a combination of these, employed to do magic. Spells traditionally were cast by many methods, such as by the inscription of runes or sigils on an object to give that object magical powers; by the immolation or binding of a wax or clay image (poppet) of a person to affect them magically; by the recitation of incantations; by the performance of physical rituals; by the employment of magical herbs as amulets or potions; by gazing at mirrors, swords or other specula (scrying) for purposes of divination; and by many other means. Necromancy (conjuring the dead) Strictly speaking, necromancy is the practice of conjuring the spirits of the dead for divination or prophecy, although the term has also been applied to raising the dead for other purposes. The biblical Witch of Endor performed it (1 Samuel 28th chapter), and it is among the witchcraft practices condemned by Ælfric of Eynsham: "Witches still go to cross-roads and to heathen burials with their delusive magic and call to the devil; and he comes to them in the likeness of the man that is buried there, as if he arises from death." Witchcraft and cunning-craft Traditionally, the terms "witch" and "witchcraft" had negative connotations. Most societies that have believed in harmful witchcraft or 'black' magic have also believed in helpful or 'white' magic. In these societies, practitioners of helpful magic provided services such as breaking the effects of witchcraft, healing, divination, finding lost or stolen goods, and love magic. In Britain they were commonly known as cunning folk or wise
