3. The Mysteries of the Druids and the ‘Drottes’

Places of Initiation. The adytum or ark of the mysteries was called a cromlech, and was used as the sacred pastos, or place of regeneration. It consisted of three upright stones, as supporters of a broad, flat stone laid across them on the top, so as to form a small cell. Kit Cotey's House, in Kent, was such a pastos. Considerable space, however, was necessary for the machinery of initiation in its largest and most comprehensive scale. Therefore, the Coer Sidi, where the mysteries of Druidism were performed, consisted of a range of buildings, adjoining the temple, containing apartments of all sizes, cells, vaults, baths, and long and artfully contrived passages, with all the apparatus of terror used on these occasions. Most frequently these places were subterranean; and many of the caverns in this country were the scenes of Druidical initiation. The stupendous grotto at Castleton, in Derbyshire [Peak Cavern], called by Stukeley the Stygian Cave, as well as the “Giants Caves” between Luckington and Badminton [in Wilts.], certainly were used for this purpose.
