On the other hand, the athame stands as one of the four elemental tools in modern occultism, traditionally standing for fire, for witches, and air, for ceremonial magicians. (From the known origins of Wicca, with Gardner's own Book of Shadows, the athame represents fire; where the wand corresponds to air. Other varieties of Wiccan practice may switch those two around.) The other three elemental tools are the wand, the pentacle, and the cup or chalice. These four magical tools correspond to four "weapons" of significance in Celtic myth—the sword, the spear, the shield, and the cauldron (and/or grail). The same four ritual tools also appear in the magical practices of the western hermetic tradition, derived from The Golden Dawn, who pioneered the modern occult tradition and new age spirituality; and they appear in tarot decks as the four card suits: swords, cups, wands, and pentacles. The athame is an elemental tool, while the sword is often a tool representing power, used to keep Spirits in check during goetic Evocation. Wiccans sometimes use the sword as a substitute for the athame.
