Whenever he appeared at the theatre, he was called upon the stage from all parts of the house; yet all this time he could not earn enough to live. He received only a hundred dollars from his "Don Giovanni," and less for the others. He gave lessons every hour he could spare, concerts in the open air, borrowed from his friends, scrimped himself, to send money to his sick wife at Baden, pawned his silver plate to make one more unsuccessful journey to win the aid of indifferent princes, and fainted often at his tasks after midnight. Still he wrote to "the best and dearest wife of my heart," "If I only had a letter from you, all would be right," and promised her to work harder than ever to earn money.
When Constance was at home with him, if he left her in the morning before she awakened, he would leave a note for her with the words, "Good-morning, my darling wife. I shall be at home at -- o'clock precisely." Once when she had been ill for eight months, and Mozart was composing beside her as she slept, suddenly a noisy messenger entered. Alarmed lest his wife should be disturbed, he rose hastily, when the penknife in his hand fell, and buried itself in his foot. Without a word escaping his lips, he left the room, a surgeon was called, and, though lame for some time, the wife was not told of the accident.
His compositions found few purchasers, for the people generally could not comprehend them. Publishers' shops were closed to him, unless he would write in the popular style. "Then I can make no more by my pen," he said bitterly, "and I had better starve and go to destruction at once." So poor had his family become, that, with no fuel in the house, he and his wife were found by a friend, waltzing to keep warm.
About this time a sepulchral-looking man called to ask that a "Requiem" be written on the death of the wife of an Austrian nobleman, who was to be considered the author, and thus his intense grief be shown, though manifested through a lie. Mozart consulted with his wife, as was his custom, and, as she indorsed it, he accepted the commission for fifty dollars. Overworked, harassed by debts which he could not pay, hurt at the jealousies and intrigues of several musicians, disappointed at the reception of his new opera at Prague, his hopeful nature forsook him, and he told Constance that the "Requiem" would be written for himself.
