through his influence his father, who had always previously opposed the order, became a member, during this visit at Vienna. Soon afterward the father died. For the lodge Mozart wrote much music, both of a liturgical character and for concerts, and special entertainments, and in the "Magic Flute" there are many reminiscences of the order. A year later he made the acquaintance of the celebrated librettist, Lorenzo da Ponte, who proposed to adapt Beaumarchais' comedy, "The Marriage of Figaro," which after some difficulty in obtaining the consent of the emperor, on account of the objectionable character of the story, was done, and the work produced at Vienna, May 1, 1786. The theater was crowded, and many airs were repeated, until at later performances the emperor prohibited encores. A pleasing scene took place at the last dress rehearsal. Kelly, who took the parts of Don Basilio and of Don Curzio, writes: "Never was anything more complete than the triumph of Mozart and his 'Marriage of Figaro,' to which numerous overflowing audiences bore witness. Even at the first full band rehearsal, all present were roused to enthusiasm, and when Benucci came to the fine passage '_Cherubino Alla Vittoria, Alla Gloria Militar_,' which he gave with stentorian lungs, the effect was electric, for the whole of the performers on the stage, and those in the orchestra, as if actuated by one feeling of delight, vociferated '_Bravo, Bravo, Maestro. Viva, Viva, grande Mozart_.' Those in the orchestra I thought would never have ceased applauding, by beating the bows of their violins against their music desks. And Mozart, I never shall forget his little animated countenance. When lighted up with the glowing rays of genius, it is as impossible to describe it as it would be to paint sunbeams." Yet the success did not improve his position in money affairs. Soon afterward, however, he was invited to Prague, to see the success his beautiful work was making there. He was entertained handsomely, and found the town wild with delight, at the novelty, the spontaneity and charming quality of his music. He also gave two concerts there, which were brilliantly successful, and having been many times recalled he sat down at the piano and improvised for half an hour, the audience resisting every effort he made to stop. After returning to Vienna he obtained another libretto from Da Ponte, that of "_Don Giovanni_," which was produced at Prague, October 29, 1787. It is told, as a characteristic incident of Mozart's method of working, that the overture of this opera had not been written until the night before the performance. At every suggestion Mozart answered, tapping his forehead, "I have it all here." But not a line had been written. Late at night he set about writing it. His wife made him some punch, of which he was very fond, and sat with him telling him fairy stories, in order to keep him awake. Early in the morning the overture
