It is believed that the painter was born not in 1646, as De Dominici reported, but around 1652, based on the discovery, by Prota Giurleo, of the act of death from which it appears that he died in Naples on 27 June 1732 at the age "of 80 years".
His work at Spanish court continued until 1700, but on his return to Naples, Belvedere abandoned painting to devote himself completely to theatrical activity.
[1] Later Belvedere departed from the style of Paolo Porpora, that is, from works with Caravaggio-like period of still lives and flowers, apparently rejecting their mere "decorative" value.
He appears to have been influenced by Giuseppe Recco and never rhetorical "Baroque" exuberance of Giovan Battista Ruoppolo, deriving from them an exalting sense of light and vitality.
[2] Among his pupils or followers were Gasparo Lopez, Baldassare de Caro, Tommaso Realfonso, and Nicola Casissa.
