Ole Bull sought out the writer of this criticism, who gave him valuable advice, and for six months he devoted himself to ardent study under the guidance of able masters. In this way he learned to know himself, the nature and limitations of his own talent. We now arrive at the point in Ole Bull's career at which he became celebrated, and this was due to accident. He was at Bologna, where De Beriot and Malibran were to appear at one of the Philharmonic concerts. By chance Malibran heard that De Beriot was to receive a smaller sum than that which had been agreed upon for her services, and in a moment of pique she sent word that she was unable to appear on account of indisposition. De Beriot also declared himself to be suffering from a sprained thumb. It happened that Madame Colbran (Rossini's first wife) had one day heard Ole Bull practising as she passed his window, and now she remembered the fact, and advised the Marquis Zampieri, who was the director of the concerts, to hunt up the young violinist. Accordingly, Ole Bull, who had gone to bed very early, was roused by a tap on the door, and invited to improvise on the spot for Zampieri. Bull was then hurried off, without even time to dress himself suitably for the occasion, and placed before a most distinguished audience, which contained the Duke of Tuscany and other celebrities, besides De Beriot, with his arm in a sling. His playing charmed and captivated the audience, although he was almost overcome with exhaustion. After taking some food and wine he appeared again, and this time he asked for a theme on which to improvise. He was given three, and, instead of making a selection, he took all three and interwove them in so brilliant a manner that he carried the audience by storm. He was at once engaged for the next concert, and made such success that he was accompanied to his hotel by a torchlight procession, and his carriage drawn home by the excited people. Ole Bull continued his triumphant course through Italy. At Lucca he played at the duke's residence, where the queen-dowager met with a surprise, as Ole refused to begin playing until she stopped talking. At Naples he experienced the misfortune of having his violin stolen, and he was obliged to buy a Nicholas Amati, for which he paid a very high price. After playing and making a great success in Rome, he returned to Paris, where he now found the doors of the Grand Opera open to him, and he gave several concerts there. In 1836 he married Felicie Villernot, the granddaughter of the lady in whose house he had met with so much kindness during his first stay in Paris. Following the advice of Rossini, he went to London, where he made his usual success, notwithstanding the intrigues of certain musicians, who endeavoured to discredit him. Such was his popularity in England that he received for one concert, at Liverpool, the sum of L800, and in sixteen months' time he gave two hundred and seventy-four concerts in the United Kingdom.
