Stephens began with the poetry collection Insurrections (1909) and gained recognition with his first novel, The Charwoman's Daughter (1912). His masterpiece, The Crock of Gold (1912), is a philosophical fantasy blending Celtic folklore with sharp social satire, following a Philosopher whose wife elopes with a Piper, drawing the gods into human affairs. Other notable works include The Demi-Gods (1914), Irish Fairy Tales (1920), and Deirdre (1923), a lyrical retelling of the ancient tragic heroine's legend. His poetry collections include Songs from the Clay (1915) and Reincarnations (1918).
During World War II, Stephens broadcast from London as "The Merry McGowan," charming listeners with his Irish wit. He died in 1950, remembered as a distinctive and beloved voice in Irish literature.
