In Yeats and Gregory's Cathleen Ní Houlihan (1902), she arrives at an Irish family's home as they are making preparations for the marriage of their oldest son.
In Yeats and Gregory's play, Kathleen Ni Houlihan tells the family her sad tale, interspersed with songs about famous Irish heroes that had given their life for her.
She ultimately lures the young groom away to join in the failed Irish Rebellion of 1798 against the British during the French Revolutionary Wars.
Richard Kearney (1988, p. 218) suggests that the Kathleen Ni Houlihan myth represents the view that the blood sacrifice of heroes is needed to free and redeem Ireland.
Seán O'Casey's The Shadow of the Gunman (1923) quotes the last line of Carbery's "The Passing of the Gael," as the character Seumas Shields complains about various aspects of Irish culture.
Irish poet Seamus Heaney has suggested that the character of Sarah in Brian Friel's Translations (1980) can be seen as a Kathleen Ni Houlihan-like figure desperately trying to regain her voice and identity.
