He left Naples in the springtime, and returned to Rome, where he met, at the Palace of the Cardinal Ottoboni, Bishop Agostino Steffani, who by a curious combination of attributes was at the same time Kapellmeister at the Court of Hanover, and charged with secret missions by different German princes.[119] Steffani was one of the most finished musicians of his time. He established a firm friendship with Handel, possibly when travelling together to Venice, where Handel's _Agrippina_ was played at the opening of the Carnival season, 1709-10, at the theatre of San Giovanni Grisostomo.[120] The success exceeded all anticipations. Mainwaring says that he took all his hearers by storm. There were great acclamations, and cries of _Viva il caro Sassone_ and extravagances impossible to record. The grandeur of the style struck them all like thunder. The Italians had good reason to rejoice, for they found in Handel a most brilliant exponent, and _Agrippina_ is the most melodious of his Italian operas. Venice then made and unmade reputations. The enthusiasm aroused by the representations at San Giovanni Grisostomo's spread itself out over the whole of musical Europe. Handel remained the whole of the winter at Venice. He seemed undecided as to what course to follow. It was quite on the cards that he should pass through Paris.[121] Handel had familiarised himself with the French language.[122] He showed, as it happened, a singular attraction for the most beautiful subjects of our French tragedy.[123] With his prodigious adaptability, and his Latin qualities, the clarity of his lines, his eloquence, logic, and his passionate love for form, he would have rejoiced exceedingly in assimilating the tradition of our art, and taking it up with an irresistible vigour.[124] But at Venice, whilst he was still hesitating what to do, he encountered the Hanoverian nobles, amongst whom was the Baron Kielmansegg, who invited him to follow them. Steffani himself had offered him with a charming grace his post as Kapellmeister at the Court of Hanover. Handel went then to Hanover. * * * * *
