Barbers also used to be surgeons and perform operations. The
barber pole is actually the symbol for the barber/surgeon, blood
and bandages. see associated www The modern barber pole originated
in the days when bloodletting was one of the principal duties of
the barber. The two spiral ribbons painted around the pole
represent the two long bandages, one twisted around the arm before
bleeding, and the other used to bind is afterward. Originally, when
not in use, the pole with a bandage wound around it, so that both
might be together when needed, was hung at the door as a sign. But
later, for convenience, instead of hanging out the original pole,
another one was painted in imitation of it and given a permanent
place on the outside of the shop. This was the beginning of the
modern barber pole.
