  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Gnomonic  \Gno*mon"ic\,  Gnomonical  \Gno*mon"ic*al\,  a.  [L. 
  gnomonicus,  Gr  ?:  cf  F.  gnomonique  See  {Gnomon}.] 
  Of  or  pertaining  to  the  gnomon,  or  the  art  of  dialing. 
 
  {Gnomonic  projection},  a  projection  of  the  circles  of  the 
  sphere,  in  which  the  point  of  sight  is  taken  at  the  center 
  of  the  sphere,  and  the  principal  plane  is  tangent  to  the 
  surface  of  the  sphere.  ``The  gnomonic  projection  derives 
  its  name  from  the  connection  between  the  methods  of 
  describing  it  and  those  for  the  construction  of  a  gnomon 
  or  dial.''  --Cyc.  of  Arts  &  Sciences.
