The  flower  of  the  chivalry  of  Munster  perished  also  on  that
fatal  field ;  for  the  seven  sons  of  OlLioll  Olum  who  had
come  to  assist  King  Art,  their  mother's  brother,  were  slain
to  a  man  on  the  field  or  in  the  rout  that  followed.
Fortunately  for  young  Cormac,  the  king's  son,  he  was
just  then  at  fosterage  in  Connaught,  probably  with  Nia  Mor,
who  was  his  cousin,  and  one  of  the  sub-kings  of  the  province
at  that  time.  So  Mac  Con,  the  usurper,  fuund  no  obstacle  to
prevent  him  assuming  the  sovereignty  of  Tara ;  and  we  are
told  that  he  reigned,  some  30  years,  from  a.d.  196  to  226.
