I know that the answer to the question "What was Die Alpen?" is in "Jean-Jacques Rousseau was the first of many to present the Alps as a place of allure and beauty, banishing the prevalent conception of the mountains as a hellish wasteland inhabited by demons. Rousseau's conception of alpine purity was later emphasized with the publication of Albrecht von Haller's poem Die Alpen that described the mountains as an area of mythical purity. Late in the 18th century the first wave of Romantics such as Goethe and Turner came to admire the scenery; Wordsworth visited the area in 1790, writing of his experiences in The Prelude. Schiller later wrote the play William Tell romanticising Swiss independence. After the end of the Napoleonic Wars, the Alpine countries began to see an influx of poets, artists, and musicians, as visitors came to experience the sublime effects of monumental nature.". Can you tell me what it is?
