This is the time of year when vampires, ghosts, and
other spirits from the nether world start appearing in stores
and on our front porches all in anticipation of Halloween. The
roots of Halloween are in the pre-Christian Druid new year
celebration. The Druid (or Gallic ) new year began November 1
which coincided with the end of the harvest which accounts for
the food aspect of the holiday.
The tradition was that the spirits of the dead would come out
the night
before (October 31) in anticipation of the new year.
The twentieth century American version of Halloween is a kind
of Dionysian festival in which a symbolic ( although some take it
literally) loss of all inhibitions leads to an equally symbolic
anything goes mentality which manifests itself in the form of
costumes portraying anti-societal characters such as pirates,
vampires, goblins, ghosts, etc.,etc.
