From Hamburg to Italy

Handel's probationary appointment to Domkirche expired in March 1703. By July Handel was in Hamburg. Since he left no explanation for the move biographers have offered their own speculation.

Donald Burrows believes that the answer can be found by untangling Mainwaring's confused chronology of the trip to Berlin. Burrows dates this trip to 1702 or 1703 (after his father's death) and concludes that since Handel (through a "friend and relation" at the Berlin court) turned down Frederick's offer to subsidise his musical education in Italy (with the implicit understanding that he would become a court musician on his return), Handel was no longer able to expect preferment (whether as a musician, lawyer or otherwise) within Brandenburg-Prussia. Since he was attracted to secular, dramatic music (by meeting the Italians Bononcini and Attilio Ariosti and through the influence of Telemann), Hamburg, a free city with an established opera company, was the logical choice.

The question remains, however, why Handel rejected the King's offer, given that Italy was the centre of opera. Lang suggests that influenced by the teachings of Thomasius, Handel's character was such that he was unable to make himself subservient to anyone, even a king. Lang sees Handel as someone who could not accept class distinctions that required him to regard himself as a social inferior. "What Handel craved was personal freedom to raise himself out of his provincial milieu to a life of culture." Burrows notes that, like his father, Handel was able to accept royal (and aristocratic) favours without considering himself a court servant; and so, given the embarrassed financial condition of his mother, Handel set off for Hamburg to obtain experience while supporting himself.

In 1703, he accepted a position as violinist and harpsichordist in the orchestra of the Hamburg Oper am Gänsemarkt. There he met the composers Johann Mattheson, Christoph Graupner and Reinhard Keiser. Handel's first two operas, Almira and Nero, were produced in 1705. He produced two other operas, Daphne and Florindo, performed in 1708.

According to Mainwaring, in 1706 Handel travelled to Italy at the invitation of Ferdinando de' Medici. (Other sources say Handel was invited by Gian Gastone de' Medici, whom Handel had met in 1703–04 in Hamburg.) Ferdinando, who had a keen interest in opera, was trying to make Florence Italy's musical capital by attracting the leading talents of his day. In Italy, Handel met librettist Antonio Salvi, with whom he later collaborated. Handel left for Rome and since opera was (temporarily) banned in the Papal States, composed sacred music for the Roman clergy. His famous Dixit Dominus (1707) is from this era. He also composed cantatas in pastoral style for musical gatherings in the palaces of duchess Aurora Sanseverino (whom Mainwaring called "Donna Laura") one of the most influential patrons from the Kingdom of Naples, and cardinals Pietro Ottoboni, Benedetto Pamphili and Carlo Colonna. Two oratorios, La resurrezione and Il trionfo del tempo, were produced in a private setting for Ruspoli and Ottoboni in 1709 and 1710, respectively. Rodrigo, his first all-Italian opera, was produced in the Cocomero theatre in Florence in 1707. Agrippina was first produced in 1709 at Teatro San Giovanni Grisostomo in Venice, owned by the Grimanis. The opera, with a libretto by Cardinal Vincenzo Grimani, ran for 27 nights successively. The audience, thunderstruck with the grandeur and sublimity of his style, applauded for Il caro Sassone ("the dear Saxon" – referring to Handel's German origins).
