In Paris, at this period, there lived a Monsieur de Caraman, Prince of Chimay, a great lover of music and very friendly to Cherubini, whom he invited to spend the summer of 1808 on his estate in Belgium, hoping that the quiet of rural life might restore the musician's failing strength. Cherubini accepted the invitation, and Auber, at that time his pupil, accompanied him to Chimay. The inhabitants of the place, having heard of the celebrated composer's arrival at the castle, sent a deputation to entreat him to compose them an ode to be sung on St. Cecilia's day. Cherubini, with harsh abruptness, refused to comply with the request. But soon afterwards the occupants of the castle saw him going about in a meditative mood, and then to set himself quietly and industriously to work. After another brief interval he called Auber to the piano, and showed him a recently completed _Kyrie_. When this had been sung through in the presence of his astonished and delighted friends, Cherubini wrote the _Gloria_, and presented both compositions to the highly elated townspeople, who gave them as satisfactory a public performance as possible, considering the very limited amount of talent at their command. This was the beginning of the celebrated F major mass for three-part chorus and orchestra. On his return to Paris, Cherubini completed the work, and in March, 1809, it was performed for the first time in the Prince's _salon_ by a select chorus and orchestra, before an audience of invited guests. In thus returning, a mature artist, to the field of his youthful endeavors, the composer was destined to exhibit his genius in its finest and most permanent qualities. The F major mass inaugurated a new order of church music, just as a new operatic style was created by "Lodoiska"; and if other opera composers came after him who followed different ideals and obscured his fame, it is an undeniable fact that the Catholic Church music of the nineteenth century can show us nothing worthy to stand by the side of Cherubini's works. He has here remained the unequalled master.
In running over the list of his compositions it is easy to see that from this time on he produced less and less of the dramatic order. In the year 1809 appeared the charming one-act Italian opera, "Pimmalione," which was performed at the Tuileries in the presence of Napoleon and the art-loving Empress Josephine. The name of the composer had not been communicated to the Emperor, who was profoundly stirred by the music; but when he learned that it was written by Cherubini, he manifested more astonishment than pleasure. Notwithstanding this, he sent the musician a handsome sum of money, and commissioned him to compose a festal ode on the occasion of his marriage to the Archduchess Marie Louise of Austria. Another one-act opera, with a French text, "Le Crescendo," was brought out in the Feydeau Theatre on the 1st of September, 1810. In 1813 there followed a work for the Grand Opera, where Cherubini had first presented his "Démophon" and "Anacréon" twenty-five years before. The new opera, however, was not well received, and a period of twenty years now elapsed before the production of another. In 1833 a remodelling of the old "Koukourgi," under the title of "Ali Baba," was given to the public. It deserves our admiration as the work of a septuagenarian, but is wholly ineffective from an artistic point of view.
