Stunden-Buch or The Book of Hours is a collection of poetry by Rainer Maria Rilke. With its dreamy, melodic expression and neo-Romantic mood, it stands as one of the most important of Rilke's early works. Rilke displayed a wide range of his poetic talent employing provocative language and use of a turn-of-the-century Art Nouveau aesthetic. The suggestive musicality of his verses developed into the hallmark of his later lyric poetry.
