How long does it take to make a tradition? Surely a longevity spanning four decades denotes a yearly gathering that has taken hold of a group’s psyche. If this is indeed the case, consider the pagan faction Bay Area Reclaiming’s Spiral Dance a full-blown, locally born folkway. The rite takes place each year during the Halloween season, or Samhain, as the pagan holiday of death and regeneration is best known. During the gathering — which also serves as Reclaiming Bay Area’s biggest fundraiser of the year — dance, acrobatics, elaborate altars, and song mark a program largely geared around the spiral dance itself, in which group members move in a whorl (widdershins, as the counterclockwise movement is known in faiths from Wicca to Judaism) that invokes rebirth as the cold season approaches. It’s a gorgeous, all-inclusive sight, regardless of the number or character of the deities to which you pay homage. (You’re invited too, atheist babes.)
