His best critical work is the Richard Wagner and Tannhäuser, a more significant essay than Nietzsche's Richard Wagner in Bayreuth; Baudelaire's polemic appeared at a more critical period in Wagner's career. Wagner sent a brief, hearty letter of thanks to the critic and made his acquaintance. To Wagner Baudelaire introduced a young Wagnerian, Villiers de l'Isle Adam. This Wagner letter is included in the volume of Crépet; but there are no letters published from Baudelaire to Franz Liszt, though they were friends. In Weimar I saw at the Liszt house several from Baudelaire which should have been included in the Letters. The poet understood Liszt and his reforms as he understood Wagner's. The German composer admired the French poet, and his Kundry, of the sultry second act, Parsifal, has a Baudelairian hue, especially in the temptation scene. The end was at hand. Baudelaire had been steadily, rather, unsteadily, going downhill; a desperate figure, a dandy in shabby attire. He went out only after dark, he haunted the exterior boulevards, associated with birds of nocturnal plumage. He drank without thirst, ate without hunger, as he has said. A woeful decadence for this aristocrat of life and letters. Most sorrowful of sinners, his morose delectation scourged his nerves and extorted the darkest music from his lyre. He fled to Brussels, there to rehabilitate his dwindling fortunes. He gave a few lectures, and met Rops, Lemonnier, drank to forget, and forgot to work. He abused Brussels, Belgium, its people. A country where the trees are black, the flowers without odour, and where there is no conversation. He, the brilliant _causeur_, the chief _blaguer_ of a circle in which young James McNeill Whistler was reduced to the rôle of a listener--this most _spirituel_ among artists found himself a failure in the Belgian capital. It may not be amiss to remind ourselves that Baudelaire was the creator of most of the paradoxes attributed, not only to Whistler, but to an entire school--if one may employ such a phrase. The frozen imperturbability of the poet, his cutting enunciation, his power of blasphemy, his hatred of Nature, his love of the artificial, have been copied by the æsthetic blades of our day. He it was who first taunted Nature with being an imitator of art, with being always the same. Oh, the imitative sunsets! Oh, the quotidian eating and drinking! And as pessimist, too, he led the mode. Baudelaire, like Flaubert, grasped the murky torch of pessimism once held by Chateaubriand, Benjamin Constant, and Sénancour. Doubtless all this stemmed from Byronism. To-day it is all as stale as Byronism.
