Here the cold archbishop, discrediting the reports of the boy's genius, shut him up alone for a week to compose an oratorio, the text furnished by himself. Mozart, only ten years old, stood the test brilliantly. The next year a second tour was taken to Vienna, to be present at the marriage of the Archduchess Maria Josepha. The bride died from smallpox shortly after their arrival: and poor Wolfgang took the disease, and was blind for nine days. When he recovered, the musicians, moved by envy and jealousy, would not be outdone by a boy of twelve, who was equally at home in German or Italian opera, and determined to hiss off the stage whatever he might compose. Sad at heart, and disappointed, again the Mozarts went back to the old home. Two years later, after much self-sacrifice, the father took his boy to Italy for study. The first day in Passion Week they went to the Sistine Chapel to hear the famous "Miserere" of Allegri, which was considered so sacred, that the musicians were forbidden to take home any part of it, or copy it out of the chapel, on pain of excommunication. Wolfgang, as soon as he reached his lodgings, wrote it out from memory; which remarkable feat for a boy of fourteen astonished all Rome. So wonderfully did he play, that the audience at Naples declared there was witchcraft in the ring which he wore on his left hand, and he was obliged to remove it. At Milan, when he was nearly fifteen, he composed the opera "Mithridate," conducting it himself, which was given twenty nights in succession to enthusiastic audiences. After this came requests for operas from Maria Theresa, Munich, and elsewhere. He was busy every moment. Overworked, he was often ill; but the need for money to meet heavy expenses made constant work a necessity. All this time he wrote beautiful letters to his mother and sister. "Kiss mamma's hand for me a thousand billion times," is the language of his loving heart. He could scarcely be said to have had any childhood; but he kept his tenderness and affection to the last of his life. After their return to Salzburg, finding the new archbishop even less cordial than the old--the former had allowed Wolfgang the munificent salary of five dollars and a fourth yearly!--it was deemed wise to try to find a new field for employment. The father, now sixty years of age, must earn a pittance for the family by giving music-lessons, while the mother accompanied the son to Paris. The separation was a hard one for the devoted father, who could not say good-by to his idolized son, and poor Nannerl wept the whole day long. Mozart, now twenty-one, and famous, well repaid this affection by his pure character. He wrote: "I have God always before me. Whatever is according to his will is also according to mine; therefore I cannot fail to be happy and contented."
