Once again Handel returned to Italian Opera. The public hatred pursued him here also. The royal family of Hanover was detested. It added to its own discredit by the scandalous disputes which took place between the King and his son. The Prince of Wales, in a spirit of petty spite against his father, who showed his affection for Handel, amused himself by attempting to ruin the composer. Encouraged by the opposition, and enchanted by the idea of making sport against the King, he founded a rival opera house, and as he could no longer set Bononcini up against Handel, as the former had been discredited by a case of flagrant plagiarism, which had an European circulation,[215] he approached Porpora, with a view to directing his theatre. "Then," says Lord Hervey, "the struggle became as serious as that of the Greens against the Blues at Constantinople under Justinian. An anti-Handelian was regarded as an anti-Royalist, and in Parliament, to vote against the Court was hardly more dangerous than to speak against Handel." On the other hand, the immense unpopularity of the King redounded on Handel, and the aristocracy combined to secure his downfall. He accepted the challenge, and after a third tour in Italy during the summer of 1733, again to recruit more singers, he bravely took up the fight with Porpora, to whom was added Hasse in 1734. They were the greatest rivals against which he had yet measured himself. But Hasse and Porpora had strong dramatic feeling, and especially were they the most perfect masters of the beautiful art of Italian melody and singing.[216] Nicolo Porpora, who came from Naples, was forty-seven years old. He had a cold but vigorous spirit, intelligent and possessing more than anyone else, except Hasse, all the resources of the Italian singing. His style was very beautiful, and it was not less broad than that of Handel. No other Italian musician of his time had such ample breadth of phrasing.[217] His writings seem of a later age than Handel's, and approximate to the time of Gluck and Mozart. Whilst Handel, despite his marvellous feeling for plastic beauty, often treated the voices as an instrument, and in his development the beautiful Italian lines occasionally became weighed down by German complexity, Porpora's music always kept within the bounds of classic purity, though the form was a little uninteresting in design. History has never done him sufficient justice.[218] He was quite worthy of measuring himself against Handel, and the comparison between Handel's _Arianna_ and that of Porpora, played at an interval of a few weeks,[219] did not prove to the advantage of the former. Handel's music is elegant, but one does not find the breadth of certain airs in Porpora's _Arianna à Naxos_. The form of these airs is perhaps of too classic a correctness, but the right Grecian breezes blow across his Roman temples.[220] He has been claimed as an Italian disciple of Gluck--a curious criticism which is bestowed occasionally on precursors.
