The  octagon  is  surrounded  by  several  chapels,  built  in  the  14th  and
15th  cent.,  and  afterwards  partly  altered.  Adjoining  the  octagon
on  the  E.  is  the  lofty  and  elegant  Gothic  Choir,  begun  by  Ritier
Gerhard  Chorus  in  1353,  and  completed  in  1413.  A  thorough  re-
storation of  the  whole  edifice  has  now  been  some  years  in  progress.
On  the  right  and  left  of  the  principal  entrance,  borne  by  modern
pillars,  are  a  brazen  Wolf,  probably  of  Roman  origin,  and  a  Pime-Conc,
dating  from  the  10th  cent.,  both  having  doubtless  once  belonged  to  a
fountain,  the  water  of  which  flowed  from  apertures  among  the  hair
of  the  wolf,  and  from  holes  in  the  pine-cone.  According  to  the
mediaeval  legend  connected  with  the  wolf,  the  funds  for  the  erection
of  the  church  having  run  short,  the  devil  offered  to  supply  the  de-
ficiency on  condition  that  the  first  living  being  that  entered  the
building  should  be  sacrificed  to  him.  The  magistrates  entered  into
the  compact,  but  defrauded  the  devil  of  his  expected  reward  by
admitting  a  wolf  into  the  sacred  edifice  on  its  completion.  The
Bronze  Doors  were  cast  about  804.
