​CESTI, MARC’ ANTONIO (1620?–1669?), Italian musical composer, was born at Florence about 1620. He was a pupil of Carissimi, and after holding a post somewhere in Florence as maestro di cappella entered the papal chapel in 1660. In 1666 he became Vice-Kapellmeister at Vienna, and died at Venice in 1669. Cesti is known principally as a composer of operas, the most celebrated of which were La Dori (Venice, 1663) and Il Pomo d’ oro (Vienna, 1668). He was also a composer of chamber-cantatas, and his operas are notable for the pure and delicate style of their airs, more suited to the chamber than to the stage.
