Both operas failed in 1737, and Handel then went back to the King's Theatre, for which he wrote his last opera _Deidamia_ in 1740. Of Handel's arrival in England, and of the manner in which his first opera was received, I have spoken in the preceding chapter. Of his previous life in Germany but little is recorded; indeed, he left that country at the age of twenty-five. It is known, however, that he was for some time engaged at the Hamburgh theatre, where operas had been performed in the German language since 1678. Rinuccini's _Dafne_, set to music by Schutz, was represented, as has been already mentioned, at Dresden in 1627, (or according to other accounts 1630); but this was a private affair in honour of a court marriage, and the first opera produced in Germany in public, and in the German language, was Thiele's _Adam and Eve_, which was given at Hamburgh in 1678. The reputation of Keiser at the court of Wolfenbüttel caused the directors of the Hamburgh Theatre, towards the close of the century, to send and offer him an engagement; he accepted it, and in the course of twenty-seven years produced as many as one hundred and sixty operas. Mattheson states that both Handel and Hasse (who was afterwards director of the celebrated Dresden Opera) formed their styles on that of Keiser.[20] Mattheson, himself a composer, succeeded Keiser as conductor of the orchestra at the Hamburgh Theatre, holding that post, however, conjointly with Handel, whose quarrel and duel with Mattheson have often been related. Handel was presiding in the orchestra while Mattheson was on the stage performing in an opera of his own composition. The opera being concluded, Mattheson proposed to take Handel's place at the harpsichord, which the latter refused to give up. The rival conductors quarrelled as they were leaving the theatre. The quarrel led to a blow and the blow to a fight with swords in the market place, which was terminated by Mattheson breaking the point of his sword on one of his antagonist's buttons, or as others have it, on the score of his own opera, which Handel carried beneath his coat. Handel went from Hamburgh to Hanover, where, as we have seen, he received an invitation from some English noblemen to visit London, and, with the permission and encouragement of the Elector, accepted it.
