Das Stunden-Buch, poetry collection in German

According to Wikipedia: "Rainer Maria Rilke (also Rainer Maria von Rilke) (4 December 1875 – 29 December 1926) is considered one of the German language's greatest 20th century poets. His haunting images focus on the difficulty of communion with the ineffable in an age of disbelief, solitude, and profound anxiety — themes that tend to position him as a transitional figure between the traditional and the modernist poets. He wrote in both verse and a highly lyrical prose. His two most famous verse sequences are the Sonnets to Orpheus and the Duino Elegies; his two most famous prose works are the Letters to a Young Poet and the semi-autobiographical The Notebooks of Malte Laurids Brigge. He also wrote more than 400 poems in French, dedicated to his homeland of choice, the canton of Valais in Switzerland."
