In this strange condition of affairs Gluck found his new sphere of labour--Gluck, himself overflowing with the revolutionary spirit, full of the enthusiasm of reform. At first he carried everything before him. Protected by royalty, he produced, on the basis of an admirable libretto by Du Rollet, one of the great wits of the time, "Iphigenia in Aulis." It was enthusiastically received. The critics, delighted to establish the reputation of one especially favoured by the Dauphiness Marie Antoinette, exhausted superlatives on the new opera. The Abbé Arnaud, one of the leading _dilettanti_, exclaimed--"With such music one might found a new religion!" To be sure, the connoisseurs could not understand the complexities of the music; but, following the rule of all connoisseurs before or since, they considered it all the more learned and profound. So led, the general public clapped their hands, and agreed to consider Gluck as a great composer. He was called the Hercules of music; the opera-house was crammed night after night; his footsteps were dogged in the streets by admiring enthusiasts; the wits and poets occupied themselves with composing sonnets in his praise; brilliant courtiers and fine ladies showered valuable gifts on the new musical oracle; he was hailed as the exponent of Rousseauism in music. We read that it was considered to be a priceless privilege to be admitted to the rehearsal of a new opera, to see Gluck conduct in nightcap and dressing-gown. Fresh adaptations of "Orpheus and Eurydice" and of "Alceste" were produced. The first, brought out in 1784, was received with an enthusiasm which could be contented only with forty-nine consecutive performances. The second act of this work has been called one of the most astonishing productions of the human mind. The public began to show signs of fickleness, however, on the production of the "Alceste." On the first night a murmur arose among the spectators--"The piece has fallen." Abbé Arnaud, Gluck's devoted defender, arose in his box and replied, "Yes! fallen from heaven." While Mademoiselle Levasseur was singing one of the great airs, a voice was heard to say, "Ah! you tear out my ears;" to which the caustic rejoinder was, "How fortunate, if it is to give you others!" Gluck himself was badly bitten, in spite of his hatred of shams and shallowness, with the pretences of the time, which professed to dote on nature and simplicity. In a letter to his old pupil, Marie Antoinette, wherein he disclaims any pretension of teaching the French a new school of music, he says--"I see with satisfaction that the language of Nature is the universal language." So, here on the crumbling crust of a volcano, where the volatile French court danced and fiddled and sang, unreckoning of what was soon to come, our composer and his admirers patted each other on the back with infinite complacency.
