Mudpuppy: You might want to check some of the material at the Camelot Project site: [http://rodent.lib.rochester.edu/camelot/cphome.stm]. This will lead you to sites which are primarily concerned with the Arthurian Legends cycle, but some of the leading scholars in Celtic Britain have entries in various bibliographies here, and you just might run across some pre-Christian rituals and shamanistic practices which are peripheral to Arthuriana. Check some British/Irish/Scottish folklore sources on the St. George Play and other similar quasi-dramatic pieces. These are generally thought to be evolutionary manifestations of pre-Christian rituals associated with Affective Magic. Good luck in your search. Bill Foster [Bill in Alabama]
