Singular to say, though he himself represented the very opposite pole of art spirit and method, Mozart was to him the greatest of his predecessors. Perhaps it was this very fact, however, which was at the root of his sentiment of admiration for the composer of "Don Giovanni" and "Le Nozze di Figaro." A story is told to the effect that Meyerbeer was once dining with some friends, when a discussion arose respecting Mozart's position in the musical hierarchy. Suddenly one of the guests suggested that "certain beauties of Mozart's music had become stale with age. I defy you," he continued, "to listen to 'Don Giovanni' after the fourth act of the 'Huguenots.'" "So much the worse, then, for the fourth act of the 'Huguenots,'" said Meyerbeer, furious at the clumsy compliment paid to his own work at the expense of his idol. Critics wedded to the strict German school of music never forgave Meyerbeer for his dereliction from the spirit and influences of his nation, and the prominence which he gave to melodramatic effects and spectacular show in his operas. Not without some show of reason, they cite this fact as proof of poverty of musical invention. Mendelssohn, who was habitually generous in his judgment, wrote to the poet Immermann from Paris of "Robert le Diable": "The subject is of the romantic order; i.e., the devil appears in it (which suffices the Parisians for romance and imagination). Nevertheless, it is very bad, and, were it not for two brilliant seduction scenes, there would, not even be effect.... The opera does not please me; it is devoid of sentiment and feeling.... People admire the music, but where there is no warmth and truth, I can not even form a standard of criticism." Schlueter, the historian of music, speaks even more bitterly of Meyerbeer's irreverence and theatric sensationalism: "'Les Huguenots' and the far weaker production 'Le Prophete' are, we think, all the more reprehensible (nowadays especially, when too much stress is laid on the subject of a work, and consequently on the libretto of an opera), because the Jew has in these pieces ruthlessly dragged before the footlights two of the darkest pictures in the annals of Catholicism, nor has he scrupled to bring high mass and chorale on the boards."
