have it in the opera was not conceived by Mariette Bey, but by Verdi while working hand in hand with the original author of the libretto, which, though designed for an Italian performance, was first written in French prose. The Italian Theatre in Cairo was built by the khedive, Ismaïl Pacha, and opened in November, 1869. It is extremely likely that the thought of the advantage which would accrue to the house, could it be opened with a new piece by the greatest of living Italian opera composers, had entered the mind of the khedive or his advisers; but it does not seem to have occurred to them in time to insure such a work for the opening. Nevertheless, long before the inauguration of the theatre a letter was sent to Verdi asking him if he would write an opera on an Egyptian subject, and if so, on what terms. The opportunity was a rare one, and appealed to the composer, who had written "Les Vêpres Siciliennes" and "Don Carlos" for Paris, "La Forza del Destino" for St. Petersburg, and had not honored an Italian stage with a new work for ten years. But the suggestion that he state his terms embarrassed him. So he wrote to his friend Muzio and asked him what to do. Muzio had acquired much more worldly wisdom than ever came to the share of the great genius, and he replied sententiously: "Demand 4000 pounds sterling for your score. If they ask you to go and mount the piece and direct the rehearsals, fix the sum at 6000 pounds." Verdi followed his friend's advice, and the khedive accepted the terms. At first the opera people in Cairo thought they wanted only the score which carried with it the right of performance, but soon they concluded that they wanted also the presence of the composer, and made him, in vain, munificent offers of money, distinctions, and titles. His real reason for not going to prepare the opera and direct the first performance was a dread of the voyage. To a friend he wrote that he feared that if he went to Cairo they would make a mummy of him. Under the terms of the agreement the khedive sent him 50,000 francs at once, and deposited the balance of 50,000 francs in a bank, to be paid over to the composer on delivery of the score.
