Deirdre of the Sorrows is a three-act play written by Irish playwright John Millington Synge, first performed at the Abbey Theatre by the Irish National Theatre Society in 1910. The play is based on Irish mythology, in particular the myths concerning Deirdre and Conchobar. The work was unfinished at the author's death in 1909, but was completed by William Butler Yeats and Synge's fiancée, Molly Allgood. [from Wikipedia]
Author

Edmund John Millington Synge (pronounced /sɪŋ/) was an Irish playwright, poet, prose writer, and collector of folklore. He was one of the cofounders of the Abbey Theatre. He is best known for the play The Playboy of the Western World, which caused riots during its opening run at the Abbey theatre. Synge wrote many well known plays, including "Riders to the Sea", which is often considered to be his strongest literary work. Although he came from an Anglo-Irish background, Synge's writings are mainly concerned with the world of the Roman Catholic peasants of rural Ireland and with what he saw as the essential paganism of their world view.
