Deirdre of the Sorrows is a 1910 drama by Irish playwright J.M. Synge, completed posthumously by his fiancée Molly Allgood and W.B. Yeats. Based on the Ulster Cycle, it tells the tragic story of Deirdre, prophesied from birth to bring strife through her beauty. Raised to be the bride of King Conchubor, she instead falls in love with Naoise and flees with him. After seven years in exile, they are lured back to Ulster under false promises of peace. Betrayed, Naoise and his brothers are slain, and Deirdre chooses death over submission to the king. The play, rich in myth and Irish cultural identity, reflects the ideals of the Irish Literary Revival and remains one of Synge’s most celebrated works.
