ritual scheme in British Traditional Wicca traditions is: Purification of the sacred space and the participants Casting the circle Calling of the elemental quarters Cone of power Drawing down the Gods Spellcasting Great Rite Wine, cakes, chanting, dancing, games Farewell to the quarters and participants These rites often include a special set of magical tools. These usually include a knife called an athame, a wand, a pentacle and a chalice, but other tools include a broomstick known as a besom, a cauldron, candles, incense and a curved blade known as a boline. An altar is usually present in the circle, on which ritual tools are placed and representations of the God and the Goddess may be displayed. Before entering the circle, some traditions fast for the day, and/or ritually bathe. After a ritual has finished, the God, Goddess, and Guardians are thanked, the directions are dismissed and the circle is closed. A central aspect of Wicca (particularly in Gardnerian and Alexandrian Wicca), often sensationalised by the media is the traditional practice of working in the nude, also known as skyclad. Although no longer widely used, this practice seemingly derives from a line in Aradia, Charles Leland's supposed record of Italian witchcraft. Many Wiccans believe that performing rituals skyclad allows "power" to flow from the body in a manner unimpeded by clothes. Some also note that it removes signs of social rank and differentiation and thus encourages unity among the practitioners. Some Wiccans seek legitimacy for the practice by stating that various ancient societies performed their rituals while nude. One of Wicca's best known liturgical texts is "The Charge of the Goddess". The most commonly used version used by Wiccans today is the rescension of Doreen Valiente, who developed it from Gardner's version. Gardner's wording of the original "Charge" added extracts from Aleister Crowley's work, including The Book of the Law, (especially from Ch 1, spoken by Nuit, the Star Goddess) thus linking modern Wicca irrevocably to the principles of Thelema. Valiente rewrote Gardner's version in verse, keeping the material derived from Aradia, but removing the material from Crowley. Sex magic Other traditions wear robes with cords tied around the waist or even normal street clothes. In certain traditions, ritualised sex magic is performed in the form of the Great Rite, whereby a High Priest and High Priestess invoke the God and Goddess to possess them before performing sexual intercourse to
