2.  As  a  set-off  to  this  donation,  we  have  the  Acts  of  a
synod  held  at  the  Lateran,  while  Charlemagne  was  still  in
Rome,  where  we  are  told  Adrian,  with  the  full  consent  of
153  bishops  and  abbots  attending  it,  bestowed  on  Charle-
magne the  right  of  choosing  the  Pope,  and  of  inducting  him
both  into  his  temporalities  and  his  see.  Bishops  and  abbots
were  bound  by  the  same  ordinance  to  resort  to  him  for
investiture,  previously  to  their  consecration.  This,  had  it
actually  taken  place,  would  have  supplied  Urban  II.  with
an  unassailable  precedent  for  the  Sicilian  monarchy  granted
by  him,  a.d.  1098,  to  Count  Eoger  of  Sicily,  which  Car-
dinal Baronius  incurred  the  wrath  of  Spain  for  calHng  in
question,

Mansi  calls  this  council  *  partim  fictitia,  partim  dubia,'
without  deciding  which  it  is  most.^  Sigebert  of  Gremblouj-s
is  the  main  authority  for  it,  but  it  is  omitted  in  some  MSS.
of  his  work.  Those  who  reject  it,  accordingly,  maintain  it
was  the  addition  of  a  partisan  in  those  MSS.  which  contain
it,  forgetting  that  partisans  have  been  known  to  omit,  as
well  as  to  add.  Gratian  not  only  records  it  as  official,  but
caps  with  it  a  similar  concession  made  to  the  first  Otho  by
Leo  VIII.,  who  quotes  the  act  of  Adrian  in  justification  of
his  own.'*  Fictitious  or  not,  it  points  to  the  fact  that  there
were  three  parties  interested  in  the  work  assigned  to  it :  an
imperial,  a  papal,  and  a  liturgical,  each  bent  on  advancing
schemes  of  its  own.
