Context: Dionysian-Dithyrambs (German: "Dionysos-Dithyramben" ) is a collection of nine poems written in the fall of 1888 by Friedrich Nietzsche under the nom de plume of Dionysos.  The first six poems ("Zwischen Raubvögeln, Das Feuerzeichen, Die Sonne sinkt, Letzter Wille, Ruhm und Ewigkeit" and "Von der Armut des Reichsten") were published in the 1891 edition of "Also sprach Zarathustra".  Other three poems ("Klage der Ariadne, Nur Narr!  Nur Dichter!"  and "Unter Töchtern der Wüste") are compositions drawn from those found in "Also sprach Zarathustra" only slightly altered.  "Ruhm und Ewigkeit" was published at the finis of the 1908 first edition of "Ecce Homo"; however, it is now deemed to be a requisite part of "Dionysos-Dithyramben". The Devil Worshippers (German: Die Teufelsanbeter ) is a six-chapter 1920 silent German film directed by the Turkish director Muhsin Ertuğrul, written by Marie Luise Droop, and featuring Carl de Vogt in the title-role of Kara Ben Nemsi.  Later horror-star Béla Lugosi is being seen in one of his first supporting roles in a film.  The film was an adaptation of a chapter from the novel "Durch die Wüste" ("Through the Desert") of German author Karl May. Across the Desert (German: Durch die Wüste) is a 1936 German adventure film directed by Johann Alexander Hübler-Kahla and starring Fred Raupach, Heinz Evelt and Aruth Wartan.  It was based on a novel by Karl May.  It was the first sound adaptation of a May novel, and the only one to be produced during the Nazi era.  Set in the Ottoman Empire during the Nineteenth century, it portrays a series of oriental adventures of the two travellers Kara Ben Nemsi and Hadschi Halef Omar. Carl Philipp Emanuel Bach (8 March 1714 – 14 December 1788), also formerly spelled Karl Philipp Emmanuel Bach, was a German Classical period musician and composer, the fifth child and second (surviving) son of Johann Sebastian Bach and Maria Barbara Bach.  His second name was given in honor of his godfather Georg Philipp Telemann, a friend of Johann Sebastian Bach. Fritz Mühlenweg (also Fritz Muhlenweg; 11 December 1898 – 13 September 1961) was a German painter and author.  His most famous book is "In geheimer Mission durch die Wüste Gobi" (part one in English "Big Tiger and Compass Mountain"), published in 1950.  It was later shortened and translated into English under the title "Big Tiger and Christian." Die Israeliten in der Wüste (The Israelites in the Desert) is an oratorio by Carl Philipp Emanuel Bach. Durch die Wüste is the first full-length solo album by German keyboardist Hans-Joachim Roedelius, best known for his work with Cluster, Harmonia, and Aquarello.  The title is German for "Through the Desert." Through the Desert is a German-style board game designed by Reiner Knizia.  It was originally released in 1998 by German game publisher, Kosmos, under the name "Durch die Wüste".  Players place pastel colored plastic camels on a hexagon-based board in an attempt to score points by capturing watering holes and reaching oases. The Hangman's Daughter (original title in German: "Die Henkerstochter" ) is a novel by Oliver Pötzsch.
