As with the stories of Cano and Derdriu (Irish tale), the story of Gráinne is thought to be one of the origins of the Tristan story. She is the Irish counterpart of Isolde.

She was the wife of the Irish chieftan Finn. Under the influence of a potion, she fell in love with Diarmaid, Finn’s nephew. The lovers eloped and began an affair.
