  From  THE  DEVIL'S  DICTIONARY  ((C)1911  Released  April  15  1993)  [devils]: 
 
  ZENITH,  n.  The  point  in  the  heavens  directly  overhead  to  a  man 
  standing  or  a  growing  cabbage.  A  man  in  bed  or  a  cabbage  in  the  pot 
  is  not  considered  as  having  a  zenith,  though  from  this  view  of  the 
  matter  there  was  once  a  considerably  dissent  among  the  learned,  some 
  holding  that  the  posture  of  the  body  was  immaterial.  These  were 
  called  Horizontalists  their  opponents,  Verticalists  The 
  Horizontalist  heresy  was  finally  extinguished  by  Xanobus  the 
  philosopher-king  of  Abara,  a  zealous  Verticalist  Entering  an 
  assembly  of  philosophers  who  were  debating  the  matter,  he  cast  a 
  severed  human  head  at  the  feet  of  his  opponents  and  asked  them  to 
  determine  its  zenith,  explaining  that  its  body  was  hanging  by  the 
  heels  outside.  Observing  that  it  was  the  head  of  their  leader,  the 
  Horizontalists  hastened  to  profess  themselves  converted  to  whatever 
  opinion  the  Crown  might  be  pleased  to  hold  and  Horizontalism  took  its 
  place  among  _fides  defuncti_.
