Franciska Danzi and Anton Raaff. Here too he met the famous Abbé Vogler, the teacher in future years of Weber and Meyerbeer, whom he disliked to the point of hatred. He sneered at his theoretical books, he called him "charlatan" and "humbug." A harsh verdict, and one not fully deserved, although this Vogler was truly an eccentric person, who boasted that he could make a composer in three weeks and a singer in six months. Now, certain members of the orchestra were engaged for concerts in Paris, and they begged Mozart to go with them, saying that Paris was the only town where such a composer would be appreciated and could make his fortune. At first he embraced their views and tried to convince his father that the plan was for the best. When everything seemed favorable, Leopold was astonished by the receipt of letters from Wolfgang, saying that he had abandoned the project, and at the same time giving ridiculous reasons for the change. The truth was that the boy was in love. Fridolin Weber, a man of good family and of education, was the prompter and the copyist of the Mannheim theatre. Poor as he was, he had cultivated the talents of his daughters. They were five in number. The second, Aloysia, was fifteen, distinguished for her beauty and superb voice. She and Mozart went together to the chateau of the Princess of Orange,--and they loved each other. She sang for the Princess and he played, and the letters written by Wolfgang to his father show more than a musician's interest in Aloysia. For her he wrote a passionate aria, choosing Metastasio's lines "Non so d'onde." This love making was stopped by a sensible and kindly letter from Leopold, and the boy and his mother set out for Paris. There were tears, and presents. Aloysia gave her lover two pairs of mittens which she had worked, and Fridolin added a roll of music paper and a copy of Molière. But Aloysia was piqued and never forgave Wolfgang for his obedience to his father. [Illustration: MARIA ANNA MOZART, Sister of the composer and remarkable as a musical prodigy.
