In 1896, his poem "Madonna" appeared in a Viennese periodical and Hesse released his first small volume of poetry, "Romantic Songs." In 1897, a published poem of his, "Grand Valse", drew him a fan letter. It was from Helene Voigt, who the next year married Eugen Diederichs, a young publisher. To please his wife, Diederichs agreed to publish Hesse's collection of prose entitled "One Hour After Midnight" in 1898 (although it is dated 1899). Both works were a business failure. In two years, only 54 of the 600 printed copies of "Romantic Songs" were sold, and "One Hour After Midnight" received only one printing and sold sluggishly. Furthermore, Hesse "suffered a great shock" when his mother disapproved of "Romantic Songs" on the grounds that they were too secular and even "vaguely sinful."
