Yet during his lifetime he was unappreciated and unsuccessful, and was a person of so little consequence that many details of his history are difficult to discover, while others which might now be interesting and instructive, are absolutely unknown. The very year and place of his birth are disputed. Some authorities claim that he was born in 1704 at Casoria, in the immediate vicinity of Naples; but the best are agreed upon the date of January 3, 1710, and name Jesi, a small town near Ancona, as the place. On the other hand, Fétis, after much examination, comes to the conclusion that he was born at Pergola, a town near Urbino,--whence his surname of Pergolese, his family name being Jesi--and sets down that the year was 1707. On this point he is evidently wrong, as he would thus make the composer older by three years at the time of his death than he is generally stated to have been. Of his boyhood nothing is known, but he must have shown in an unusual degree the musical talent so common in Italy, because he is found at about ten years of age as a charity student in Naples, and under the protection of the Duke of Maddaloni and Prince of Stigliano, the latter being first equerry to to the King of Naples. Here again accounts differ. On the one hand it is claimed that the boy was received into the Conservatory Dei Poveri di Gesú Cristo, while on the other it is argued with much probability that he was taught at San Onofrio. If the latter be accepted as the truth, the contradiction can be explained by the fact that his teacher, Gaetano Greco, was originally at the former institution, but spent his later years in connection with the latter. As the lad showed small aptitude for vocal music, he was first set to learn the violin of Domenico Mattei, who soon discovering the nature of his talent, sent him to Greco. This eminent master, himself a distinguished pupil of the great Alessandro Scarlatti, found Pergolese to be well worth cultivating and devoted himself to him with loving care. But in about two years Greco died, and Pergolese then received instruction from Durante, the famous master of counterpoint, whose methods are still followed in the royal conservatory at Naples, and from Feo. During this period his attention was concentrated upon the science of music and composition, and it is recorded that by the time he was fourteen years old, he had written some things of considerable consequence.
