Goll mac Morna
(or Goal mac Morn
) was a member of the fianna
and an uneasy ally of Fionn mac Cumhail
in the Fenian Cycle
of Irish mythology
. He had killed Fionn's father, Cumhal
, and taken over the leadership of the fianna, but when Fionn grew up and proved his worth Goll willingly stepped aside in his favour.
His given name was Áed. He gained the name Goll ("one-eyed") when he lost an eye in his battle with Cumhal.
