Adaon ab Taliesin
 

Adaon, or Avaon as he's sometimes known, a bard himself, is also the son of Taliesin, the chief of the bards.  He is also celebrated for his valour.

 

In the Triads he is one of the three dauntless chieftains who feared nothing in the day of battle,  but rushed onwards regardless of death.

 

This courage and daring supported him through all the dangers of war. He fell at length by the hand of an assassin, Llawgad Trwm Bargawd or Llawgad Trwm Bargawd Eiddyn, whose name is preserved only as the perpetrator of this crime.
 

The bold and determined character of Adaon appears to have continued even after death, for there is a Triad in which Avaon is spoken of as one of the grave-slaughtering ones, so called from their having avenged their wrongs from their graves.
 

None of his poetry is known to be preserved, except the following which is given in the Englynion y Clyweid.-Myv. Arch. I. 173.

"Hast thou heard what Avaon sang,
The son of Taliesin, of the recording verse?
The cheek will not conceal the anguish of the heart."
