GANELON OF MAINZ was the stepfather of Roland, against whom he bore a grudge. He contrived to bring about his destruction by betraying him to the Saracens, who over-powered and killed him in the Valley of Roncesvalles, as related in the well-known "Chanson de Roland." VALHALLA'S HALL. King Ludwig I of Bavaria ordered a Greek temple to be built on the banks of the Danube near Regensburg, to which he gave the name of Valhalla. In this the busts of all great Germans are placed--as, for instance, with great ceremony, that of Bismarck some years ago, and recently that of Wagner. Atta Troll's epitaph is a satirical imitation of the poetic effusions of Ludwig I, who considered himself a poet but was nothing more than an affected versifier. His mania for compression and for participial forms (not to be tolerated in German) more than once drew the arrows of Heine's wit. The last line: "Talent none, but character," has become a familiar phrase in Germany. CANTO XXV PYRENEEAN LAFAYETTE. Lafayette fought for the Revolution in France as well as in America. "THAT WHICH SONG WOULD MAKE ETERNAL," &c. A quotation in a semi-satiric vein from Schiller's "The Gods of Greece." CANTO XXVI DROVE THE SNAKES AND LIONS FAR. A burlesque quotation from Freiligrath's poem "Der Löwenritt," from which also the reference later on to the crocodile is taken. CANTO XXVII VARNHAGEN VON ENSE (1785-1858). After abandoning his career as a diplomat, von Ense married the celebrated Rahel. He lived in Berlin, where the salon of his wife became the meeting-ground for artists and writers. In his youth he associated closely with the romantics--de la Motte Fouqué, Chamisso, and Clemens Brentano, the brother of Bettina von Arnim. Though imitating the heavy and cautious style of the later Goethe he was a good writer, and his biographies of celebrated men belong to the best in German literature. He endeavoured, but without success, to win over the all-powerful Austrian Minister Metternich to the cause of "Young Germany."
