Tripod
Tools of Witchcraft

No, not a camera tripod: this tripod is based on ritual equipment from the Oracle of Delphi. The Pythoness at Delphi sat atop a tripod, a high three-legged stool, overlooking a steaming chasm that allegedly inspired psychic vision in order to deliver her prophesies. The key to the tripod is the three legs.

Early Greek altars were sometimes placed on a tripod. The most common modern tripod is essentially a cauldron standing on three legs (see Cauldron).
