In her life, Edna St. Vincent Millay wrote a lot of plays and poetry collections. The most famous one is "The Ballad of the Harp-Weaver." This book won her the Pulitzer Prize for poetry in 1923. Also, as a good writer, she wrote five plays early in her living. For example, "The Lamp and the Bell" would be the best play she wrote in the 1920s. Published in 1921, "The Lamp and the Bell" was a play written for Vassar College about love between women. Moreover, she also wrote down "The King's Henchman" in 1927. This opera was described as “the most effectively and artistically wrought American opera ever to reach the stage.”
