Task: Question Generation
Input (English): Passage: Handel's earliest opera compositions, in the German style, date from his Hamburg years, 1704–06, under the influence of Johann Mattheson. In 1706 he traveled to Italy where he remained for three years, developing his compositional skills. He first settled in Florence where he was introduced to Alessandro and Domenico Scarlatti. His first opera composed in Italy, though still reflecting the influence of Hamburg and Mattheson, was Rodrigo (1707, original title Vincer se stesso ê la maggior vittoria), was presented there. It was not particularly successful, but was part of Handel's process of learning to compose opera in the Italian style and to set Italian words to music.Handel then spent time in Rome, where the performance of opera was forbidden by Papal decree, and in Naples. He applied himself to the composition of cantatas and oratorios; at that time there was little difference (apart from increasing length) between cantata, oratorio and opera, all based on the alternation of secco recitative and aria da capo. Works from this period include Dixit Dominus and the dramatic cantata Aci, Galatea e Polifemo, written in Naples. While in Rome, probably through Alessandro Scarlatti, Handel had become acquainted with Cardinal Grimani, a distinguished diplomat who wrote libretti in his spare time, and acted as an unofficial theatrical agent for the Italian royal courts. He was evidently impressed by Handel and asked him to set his new libretto, Agrippina. Grimani intended to present this opera at his family-owned theatre in Venice, the Teatro San Giovanni Grisostomo, as part of the 1709–10 Carnevale season.
Output (English): What is the name of the person that was introduced to Alessandro and Domenico Scarlatti?
