The tradition of Befana appears to incorporate other pre-Christian popular elements as well, adapted to Christian culture and related to the celebration of the New Year. Historian Carlo Ginzburg relates her to Nicnevin. The old lady character should then represent the "old year" just passed, ready to be burned in order to give place to the new one. In many European countries the tradition still exists of burning a puppet of an old lady at the beginning of the New Year, called Giubiana in Northern Italy, with clear Celtic origins. Italian anthropologists Claudia and Luigi Manciocco, in their book "Una casa senza porte" ("A House without Doors") trace Befana's origins back to Neolithic beliefs and practices. The team of anthropologists also wrote about Befana as a figure that evolved into a goddess associated with fertility and agriculture.
