It was not particularly easy to make an opera out of the play, and Gallet and I worked together at it with considerable difficulty. We soon saw that we should have to eliminate the famous scene of the casting of the statue. When we reached this point in the play, Benvenuto had already done a good deal of singing, and this scene with its violence seemed certain to exceed the strength of the most valiant artist. In connection with our _Proserpine_, I have been accused of supposing that Vacquerie had genius. It would be too much to say that he had genius, but he certainly had great talent. His prose showed a classical refinement, and his poetry, in spite of fantastic passages which no one could admire, was sonorous in tone, contained precious material, and was both interesting and highly individual. What allured me in _Proserpine_ was the amount of inner emotion there was in the drama, which is very advantageous to the music. Music gives expression to feelings which the characters cannot express, and accentuates and develops the picturesqueness of the piece; it makes acceptable what would not even exist without it. Vacquerie approved highly the convent scene which Gallet invented. This introduced a quiet and peaceful note amidst the violence of the original work. Gallet wrote a sonnet in Alexandrine verse for Sabatino's declaration of his love. I was unable to set this to music, for the twelve feet embarrassed me and prevented my getting into my stride. As I did not know what else to do, I took the sonnet and by main force reduced the verse to ten feet with a caesura at the fifth foot. I took this to my dear collaborator in fear and trembling, and, as I had feared, he at once fell into the depths of despair. "That was the best thing in my work," he said. "I nursed and caressed that sonnet, and now you have ruined it." In the face of this despair, I screwed up my courage. As I had previously cut down the verse, I now tried lengthening out the music. Then, I sang both versions to the disconsolate poet. And what a miracle! He was altogether reconciled, approved both versions, and did not know which one to choose. We ended with a patchwork. The two quatrains are in verses of ten feet, and the two tiercets in Alexandrine metre. Outside of our work, too, our relations were delightful. We wrote to each other constantly in both prose and verse; we bombarded each other with sonnets; his letters were sometimes ornamented with water colors, for he drew very well and one of his joys was to cover white paper with color. Gallet drew the sketches for the desert in _Le Roi de Lahore_ and the cloister in _Proserpine_.
