empire  ;  but  the  austerity  of  his  chsracter  oauaed  him
to  be  very  little  re^tted. It  is  aaid  that  he  meditated

n  native  of  Sicca,  in  Nnmidia,  who  is  aappoied  to  have
lived  -between  180  and  240  A.D. He  was  s  member
of  the  medical  profession,  and  has  left  behind  him  two
works :  the  one  entitled,  **  Libri  Qaiiqitt  lardanm
pafsimtun,"  and  tbe  other,  **  Lihri
tret  etleruoi  me  aeulcrum  wuntmum."  Both  are
drawn  front  Greek  authors  \  from  Themison,  Thessa-
1ns,  and,  above  all,  Soianua. C»Uua  Aurelianus  being
the  only  antbor  of  the  sect  called  Methodista  who  has
come  down  to  ae  (if  we  ejxept  Oetavins  Horstianua,
iriio  lived  in  the  da^  of  Oe  Emperor  V^ratiniaD,  and
la  little  known),  faia  work  is  puticniarij  nluable,  as
preserving  to  ns  an  account  of  many  theories  and  views
of  practice  which  would  odwrwise  have  been  lost;  but
even  of  itself  it  ia  deserving  of  much  attention  (or  the
]»actical  infonnation  which  it  contains. Cslius  is  le-
mariiable  for  learning,  understanding,  and  scrupubMs
accuracy ;  but  bia  style  is  much  loaded  with  technical
tenos,  and  no  means  elegant. He  baa  treated  of
the  moat  important  diseases  whicb  come  under  tbe  care
of  the  f^ysicisn  in  die  following  manner. In  tbe  first
place,  he  gives  a  very  circumstantial  account  of  tbe
^mptoms,  which  he  does,  however,  more  like  a  lyste-
matic  writer  and  a  comfriler,  than  as  an  original  ob-
server of  nature. Nef  t,  be  is  at  great  pains  to  poant
out  the  distinction  between  the  disease  he  is  treating
of  and  those  vrhieh  very  nuily  resemble  it.'  HeafW
ward  endeavours  to  determine  tbe  ntf  m«  and  aeat  of
the  disease ;  and  this  part  frequently  contains  valuable
references  to  tbe  works  of  Erasistratus,  the  celebrated
Alexandrean  anatomist. Then  comes  Us  account  of
tbe  trestment,  which  is,  in  geneni,  sensible  and  sci-
entific, but  somewhat  too  formal,  timid,  and  fettered
by  tbe  rales  of  the  sect. He  ia  nvenious,  bowevttr,  in
Mien  delivering  a  free  statemeut  w  modes  of  practice,
essentially  dinerent  from  his  own.
