OSS-kar
Son of Oisín and grandson of Fionn mac Cumhaill, celebrated as one of the fiercest warriors of the Fianna.
Oscar ("deer-lover," continuing his father Oisín's deer-associated name) grows up to become one of the Fianna's most feared fighters, known for a battle-fury that echoes his grandfather Fionn's own youthful exploits. He is a constant presence at Fionn's side through the Fianna's later campaigns, bound as much by personal loyalty as by blood.
His death at the Battle of Gabhra, fighting on opposite sides from his own kin in a war between the Fianna and the High King, is remembered as the blow that breaks Fionn's spirit and marks the beginning of the Fianna's decline — grief for Oscar is one of the recurring themes Oisín returns to centuries later when recounting the Fianna's story to St. Patrick.
Oscar's name is usually explained as "deer-lover", from Irish os, "deer", and cara, "friend". As the son of Oisín he belongs to the third generation of the Fianna, and he is shown as quick-tempered and quick to act. In the tale of the Battle of Gabhra, the Cath Gabhra, he faces Cairbre Lifechair, the son of Cormac mac Airt, and Oscar kills him but is himself mortally wounded.
The battle is regularly given as the end of the Fianna, and Oscar's death is told with a good deal of grief. In some tellings his wife Aideen dies of sorrow, and a dolmen on the Hill of Howth, in Dublin, is known as Aideen's Grave. The name Oscar spread across Europe in the eighteenth century through James Macpherson's Ossian poems, which is one reason it is still common as a given name.
