Italian painter, born at Naples; studied under various celebrated masters at Naples, Rome, Lombardy, and other places, finally returning to Naples; in 1692 he received a commission from Charles II. of Spain to adorn the Escurial, and in the execution of this work remained at Madrid till 1700, when he again settled in his native city; he was famous in his day for marvellous rapidity of workmanship, but this fluency combined with a too slavish adherence to the methods of the great masters has somewhat robbed his work of individuality; his frescoes in the Escurial at Madrid and others in Florence and Rome are esteemed his finest work (1632-1705).
