With Mozart's return to Germany in 1779, being then twenty-three years of age, comes the dawn of his classical period as a composer. The greater number of his masses had already been written, and now he settled himself in serious earnest to the cultivation of a true German operatic school. This found its dawn in the production of "Idomeneo," his first really great work for the lyric stage. The young composer had hard struggles with poverty in these days. His letters to his father are full of revelations of his friction with the little worries of life. Lack of money pinched him close, yet his cheerful spirit was ever buoyant. "I have only one small room; it is quite crammed with a piano, a table, a bed, and a chest of drawers," he writes. Yet he would marry; for he was willing to face poverty in the companionship of a loving woman who dared to face it with him. At Mannheim he had met a beautiful young singer, Aloysia Weber, and he went to Munich to offer her marriage. She, however, saw nothing attractive in the thin, pale young man, with his long nose, great eyes, and little head; for he was anything but prepossessing. A younger sister, Constance, however, secretly loved Mozart, and he soon transferred his repelled affections to this charming woman, whom he married in 1782 at the house of Baroness Waldstetten. His _naïve_ reasons for marrying show Mozart's ingenuous nature. He had no one to take care of his linen, he would not live dissolutely like other young men, and he loved Constance Weber. His answer to his father, who objected on account of his poverty, is worth quoting:-- "Constance is a well-conducted, good girl, of respectable parentage, and I am in a position to earn at least _daily bread_ for her. We love each other, and are resolved to marry. All that you have written or may possibly write on the subject can be nothing but well-meant advice, which, however good and sensible, can no longer apply to a man who has gone so far with a girl." Poor as Mozart was, he possessed such integrity and independence that he refused a most liberal offer from the King of Prussia to become his chapel-master, for some unexplained reason which involved his sense of right and wrong. The first year of his marriage he wrote "Il Seraglio," and made the acquaintance of the aged Gluck, who took a deep interest in him and warmly praised his genius. Haydn, too, recognised his brilliant powers. "I tell you, on the word of an honest man," said the author of the "Creation" to Leopold Mozart, the father, who asked his opinion, "that I consider your son the greatest composer I have ever heard. He writes with taste, and possesses a thorough knowledge of composition."
