The original material in the rituals brought to light by Gardner is not cohesive, and mostly takes the form of substitutions or expansions within unoriginal material. Roger Dearnaley, in "An Annotated Chronology and Bibliography of the Early Gardnerian Craft", describes it as a "patchwork". One element that is apparently distinctive is the use of ritual scourging and binding as a method of attaining an ecstatic trance for magical working. Hutton argues strongly that this practice in Wicca does not reflect sado-masochistic sexuality (he refers in this connection to Gardner's own collection of very mild, quasi-pornographic material, which showed no traces of such interests), but is simply a practical method of work alternative to drugs or other more strenuous methods.
