Rossi wrote the operas "Il Sejano," "Clorilda," "Mitrane." The beautiful aria "Ah! rendimi," well known to all singers, is from his opera "Mitrane." Luigi Rossi, of whose presence in Rome we hear as early as the year 1620, was also a very talented composer. His only known opera is "Il palazzo incantato." But none of these composers rivalled, either in talent or reputation, their great contemporary, Alessandro Scarlatti, who was born in 1659 at Trapani in Sicily and died in 1725 at Naples. He was a pupil of Carissimi. The secret of his great power lay in his recognition of the true value of counterpoint. He was wise enough to see that the art for which Peri and Monteverde had expressed their undisguised contempt, formed the technical basis of all true greatness in music. Scarlatti was considered the most learned musician, as well as the greatest genius of the age. His power of production was almost incredible. His first opera, "L'Onesta nell Amore" (1680), was followed by no less than a hundred and fourteen other operas. He is known to have written two hundred masses, and far more than that number of cantatas. Very few of these were printed, and the majority have been consequently lost. Signs of rapid progress are everywhere apparent in these operas,--most of all in the recitative and the form of the aria. Scarlatti is supposed to be the inventor of the recitative obligato (with accompaniment) and the da capo (repetition of a musical movement). His son, Domenico Scarlatti, of whom we shall have later to speak, became one of the greatest harpsicord players on record. Alessandro's greatest contemporaries in Germany were the older members of the Bach family, who steadily made advances in musical art, more especially in the higher branches of sacred music, culminating in the great Sebastian Bach.

Nevertheless, the century gave birth to some composers whose genius was not merely great in comparison with the talent displayed by contemporary writers, but so truly great in itself that it seems impossible they should ever be forgotten. Among the Italian followers of Scarlatti was the favorite pupil of Legrenzi, Antonio Lotti (1667-1740). He invested the form left by Scarlatti with a melodious grace so modern in character that some of his arias, e. g. "Pur dicesti," are still regarded as standard compositions. He wrote more than twenty operas. In 1756 he was elected maestro di capella at St. Mark's, and in the same year he was commissioned by the Venetian Republic to compose, in honor of the Doge's wedding the Adriatic, the famous "Madrigale per il Bucintoro," entitled "Spirito di Dio."
