Gluck at the Trianon. From painting by E. J. C. Hamman.

"Iphigenia" was produced on April 19, 1774, and Marie Antoinette applauded from the royal box without ceasing. On the first representation, opinions were divided, but at the second performance the approval was unanimous. When Marie Antoinette became queen shortly afterward, she gave the composer a pension of six thousand francs, with the entrée to her morning receptions. He often visited her at Trianon, where the daughter of Maria Theresa was always gracious to the forester's gifted son. The next work of Gluck to be given in Paris was his "Orpheus and Eurydice," whose success was greater than that of the "Iphigenia," and caused Rousseau to publicly acknowledge that he was mistaken in asserting that the French language was unsuitable to set to music. He also said that the music of "Orpheus" had reconciled him to existence, and met the reproach that Gluck's work was lacking in melody with the words, "I believe that melody proceeds from every pore."

When the composer's next opera, "Alcestis," was produced, in 1776, the queen gave it her decided approbation, and loyally supported Gluck against the king's preference for the older form of opera, and the partisans of the Italian composer Piccini, who was Gluck's rival for the favour of the Parisians. Great was the battle between the warring factions, the "Gluckists" and the "Piccinists," whose differences of opinion sometimes even resulted in personal encounters in the theatre. Between the two composers themselves, matters were more pleasant. When Piccini's "Roland" was being studied, the composer, unused to conducting and unfamiliar with the French language, became confused at a rehearsal. Gluck happened to be present, and, rushing into the orchestra, threw off his wig and coat, and led the performance with such energy and skill that all went smooth again. On the other hand, Piccini, when he learned of the death of his whilom rival, expressed his respect for Gluck by starting a subscription for the establishment of an annual concert to be given upon the anniversary of the composer's death, at which nothing but his music should be performed.

Gluck's "Armida" was given its first presentation in 1777, and increased his fame so much that his bust was placed in the Grand Opera beside those of Lulli, Rameau, and Quinault. "Iphigenia in Tauris" was produced in 1779, with great success, but "Echo and Narcissus," the last opera which Gluck gave in Paris, was a failure. He left France for Vienna in the same year, never to return, though his royal pupil pressed him to do so in the most flattering manner.

Before taking leave of Gluck, let us read the eloquent words with which Ernest Newman closes his book on "Gluck and the Opera." "The musician speaks a language that is in its very essence more impermanent than the speech of any other art. Painting, sculpture, architecture, and poetry know no other foe than external nature, which may, indeed, destroy their creations and blot out the memory of the artist. But the musician's material is such that, however permanent may be the written record of his work, it depends not upon this, but upon the permanency in other men of the spirit that gave his music birth, whether it shall live in the minds of future generations. Year after year the language of the art grows richer and more complex, and work after work sinks into ever-deepening oblivion, until music that once thrilled men with delirious ecstasy becomes a dead thing, which here and there a student looks back upon in a mood of scarcely tolerant antiquarianism. In the temple of the art a hundred statues of the gods are overthrown; and a hundred others stand with arrested lips and inarticulate tongues, pale symbols of a vanished dominion which men no longer own. Yet here and there, through the ghostly twilight, comes the sound of some clear voice that has defied the courses of the years and the mutations of taste; and we hear the rich canorous tones of Gluck, not, perhaps, with all the vigour and the passion that once was theirs, but with the mellowed splendour given by the touch of time. Alone among his fellows he speaks our modern tongue, and chants the eternal passions of the race. He was, indeed, as Sophie Arnould called him, 'The musician of the soul;' and if we have added new strings to our lyre, and wrung from them a more poignant eloquence than ever stirred within the heart of Gluck, none the less do we perceive that music such as his comes to us from the days when there were giants in the land."
