Nicoio Jomelli, an Italian composer, born in Aversa, near Naples, in 1714, died in Naples, Aug. 28, 1774. He was a pupil of Leonardo Leo. His Errore amoroso and Odoardo, produced in Naples before he was 24 years of age, established his reputation, and he was invited to Rome, where he composed two new operas. Thence he went to Bologna, where he studied under Padre Martini. After a successful career in the chief cities of Italy, he returned in 1749 to Rome, where his Artaserse was coldly received. In the following year he produced his Achille in Sciro with complete success in Vienna, where he made a congenial friend in the poet Metastasio, whose Didone he set to music, and on whose works he thenceforth almost exclusively employed himself. Returning to Rome in 1751, he was made chapelmas-ter of St. Peter's, but resigned in 1753 to accept an invitation from the duke of Wurtemberg to settle as musical director in Stuttgart. He returned to Naples in 1768; but his style no longer pleased, and his Dcmofoonte and Ifigenia in Aulide failed.

The Miserere was the last and greatest of his works.
