Arrived in Hamburg, in the year 1703, Handel soon made the acquaintance of Mattheson, an intelligent and industrious young musician, who was competent to appreciate the genius of Handel, and faithfully to record the progress of the promising youth during his sojourn in Hamburg, which lasted about three years. Mattheson was four years older than Handel,--a difference which, between two lads of twenty-two and eighteen, is not without some weight in their mutual intercourse, especially if the elder is already enjoying a certain success, while the younger is a new comer, intent upon gaining a footing. Mattheson's observations about Handel, although occasionally tinged with jealousy of his talented brother artist, are therefore particularly noteworthy in the biography of the great composer. Johann Mattheson, born in Hamburg, in the year 1681, was at the time of Handel's arrival tenor singer and musical composer at the theatre of the town, and teacher of singing, the harpsichord, and thorough-bass. When, in the year 1705, an increasing deafness compelled him to relinquish his engagement as singer and actor in operas at the theatre, his accomplishments, combined with commendable habits of industry and punctuality, induced the British Ambassador at Hamburg to engage him as tutor for his son, and afterwards to appoint him his secretary. During an active life of unusual duration,--he died in the year 1764, at the age of 83,--Mattheson published a great number of treatises on musical subjects, some of which still possess value as books of reference. His vanity, not unfrequently exhibited in his writings, may in some measure have been nourished by his many flatterers among his musical contemporaries, who evidently feared his sarcastic pen all the more because they did not possess the literary ability to engage successfully in a controversy with him when they disagreed with his opinion.
