At Venice he was highly praised, but at Bologna he won the celebrity which continued through life. Malibran was to sing in two concerts, but feigned illness when she learned that the man she loved, De Beriot, was to receive a smaller sum than herself, and would not appear. The manager of the theatre was in despair. Meantime, in a poor hotel, in an upper room, Ole Bull was composing his concerto in the daytime, and playing on his violin at night by his open window. Rossini's first wife heard the music, and said, "It must be a violin, but a divine one. That will be a substitute for De Beriot and Malibran. I must go and tell Zampieri" (the manager). On the night of the concert, after Ole Bull had been two hours in bed from weariness, Zampieri appeared, and asked him to improvise. He was delighted, and exclaiming, "Malibran may now have her headaches," hurried the young artist off to the theatre. The audience was of course cold and disappointed till Ole Bull began to play. Then the people seemed to hold their breath. When the curtain fell, he almost swooned with exhaustion, but the house shook with applause. Flowers were showered upon him. He was immediately engaged for the next concert; a large theatre was offered him free of expense, one man buying one hundred tickets, and the admiring throng drew his carriage to the hotel, while a procession with torchlights acted as guard of honor. Ole Bull had stepped into the glory of fame in a single night. Henceforth, while there was to be much of trial and disappointment, as come to all, he was to be forever the idol of two continents, drawing crowded houses, honored by the great, and universally mourned at his death. He had come to fame as by accident, but he had made himself worthy of fame. Malibran at first seemed hurt at his wonderful success in her stead, but she soon became one of his warmest friends, saying, "It is your own fault that I did not treat you as you deserved. A man like you should step forth with head erect in the full light of day, that we may recognize his noble blood." From here he played with great success at Florence and Rome, at the latter city composing his celebrated "Polacca Guerriera" in a single night, writing till four o'clock in the morning. It was first conceived while he stood alone at Naples, at midnight, watching Mount Vesuvius aflame. Returning to Paris, he found the Grand Opera open to him. Here, at his first performance, his a-string snapped; he turned deathly pale, but he transposed the remainder of the piece, and finished it on three strings. Meyerbeer, who was present, could not believe it possible that the string had really broken.
