He drew not only from the sources of learned and refined music--the music of musicians; but also drank deeply from the founts of popular music--that of the most simple and rustic folk.[288] He loved the latter. One finds noted down in his manuscripts the street cries of London, and he once told a friend that he received many inspirations for his best airs from them.[289] Certain of his oratorios, like _L'Allegro ed Il Penseroso_, are threaded with remembrances of his walks in the English country, and who can ignore the _Pifferari_ (Italian peasant's pipe) in _The Messiah_, the Flemish carillon in _Saul_, the joyous popular Italian songs in _Hercules_, and in _Alexander Balus_? Handel was not an artist lost in introspection. He watched all around him, he listened, and observed. Sight was for him a source of inspiration, hardly of less importance than hearing. I do not know any great German musician who has been as much a visual as Handel. Like Hasse and Corelli, he had a veritable passion for beautiful pictures. He hardly ever went out without going to a theatre or to a picture sale. He was a connoisseur, and he made a collection, in which some Rembrandts[290] were found after his death. It has been remarked that his blindness (which should have rendered his hearing still more sensitive, his creative powers translating everything into sonorous dreams) soon paralysed his hearing when its principal source of renewal was withdrawn. Thus, saturated in all the European music of his time, impregnated with the music of musicians, and the still richer music which flows in all Nature herself, which is specially diffused in the vibrations of light and shade, that song of the rivers, of the forest, of the birds, in which all his works abound, and which have inspired some of his most picturesque pages with a semi-romantic colour,[291] he wrote as one speaks, he composed as one breathes. He never sketched out on paper in order to prepare his definite work. He wrote straight off as he improvised, and in truth he seems to have been the greatest improviser that ever was. Whether extemporising on the organ at the midday services in St. Paul's Cathedral, or playing the _capriccios_ during the _entr'actes_ of his oratorios at Covent Garden--or improvising on the clavier in the orchestra at the opera, at Hamburg or in London, or "when he accompanied the singers in a most marvellous fashion, adapting himself to their temperament and virtuosity, without having any written notes," he astounded the connoisseurs of his time; and Mattheson, who may hardly be suspected of any indulgence towards him, proclaimed that he had no equal in this. One can truly say that "he improvised every minute of his life." He wrote his music with such an impetuosity of feeling, and such a wealth of ideas, that his hand was constantly lagging behind his thoughts, and in order to keep pace with them at all he had to note them down in an abbreviated manner.[292] But (and this
