in these towns refilled the drained purse; in 1770, the pope ennobled the boy, giving him the cross of the Golden Spur; and he was received into the famous _accademia filarmonica_ of Bologna. Meanwhile Wolfgang was considering the opera promised for Milan, and the 26th of December, 1770, "Mitridate, re di Ponto" was produced and received with unbounded enthusiasm. It was given twenty times, and the impresario hastened to make a new contract with the _cavaliere filarmonico_, as the Milanese called him. Father and son then visited Turin and Venice, and about this time Wolfgang probably wrote the oratorio "Betulia liberata." In the spring of 1771 they returned to Salzburg, where they found a letter from Count Firmian asking for a pastorale to celebrate the wedding of the Archduke Ferdinand with the Princess Beatrice of Modena. And now the boy fell in love with a woman ten years his elder. She was betrothed to another, and her marriage and Wolfgang's return to Milan in August ended the affair. Although in the house where he lodged, violinists, a singing teacher, and an oboe player plied assiduously their business, Wolfgang finished the promised composition, "Ascanio in Alba" in twelve days. It was first heard October 17. Its success was so great that Hasse's opera "Ruggiero" was neglected; and the kindly veteran simply said, "This young rascal will cause us all to be forgotten."

No. 9 Getreidegasse.] About the time that Wolfgang returned home, December, 1771, Sigismund, the Archbishop, died, and Hieronymus ruled in his stead. He was a man of mean and tyrannical spirit, and his reputation had preceded him, so that when he arrived in Salzburg he was received in gloomy silence. Nevertheless there were festivities, and Wolfgang wrote "Il sogno di Scipione," a composition unworthy of his pen. It was in this same year, 1772, that Dr. Charles Burney received a letter from a correspondent, saying that the lad was still a pianoforte virtuoso of great merit, but that as a composer he had reached his limit; and the writer then moralized over musical precocities, comparing them to premature fruits. Yet at this same epoch, Wolfgang wrote the celebrated Litany "de venerabile." In November he visited Milan again to compose and put on the stage the opera "Lucio Silla." There were many obstacles before and even during the representation; but the success of the work was unquestioned. This was the last opera written by Wolfgang for Italy. The impresarios were willing and eager; but the Archbishop was reluctant in granting even ordinary favors to his servant. And here is the end of the first period of Mozart's musical career.
