In Italy, a tradition developed for re-enacting the birth of Christ
and the construction of scenes of the nativity. This is said to have
been introduced by Saint Francis as part of his efforts to bring
spiritual knowledge to the laity.
Saints Days have also contributed to our Christmas celebrations. A
prominent figure in today's Christmas is Saint Nicholas who for
centuries has been honored on December 6th. He was one of the
forerunners of Santa Claus.
Another popular ritual was the burning of the Yule Log, which is
strongly embedded in the pagan worship of vegetation and fire, as well
as being associated with magical and spiritual powers.
