an eminent painter, so called by way of contraction from Giuseppe d'Arpino the town of Naples where he was born in 1560. Being carried to Rome very young, and employed by painters then at work in the Vatican to grind their colours, he soon made himself master of the elements of design, and by degrees grew very famous. His wit and humour gained him the favour of popes and cardinals, who found him buffoonery in plenty. Gregory XIII showed him great respect; and Louis XIII, of France made him a knight of the order of St Michael. By the force of a happy genius he acquired a light and agreeable manner of designing; though it is remarked by De Piles, that he degenerated into a style which neither partook of true nature nor of the antique. His battles in the Capitol are the most esteemed of all his pieces. He died at Rome in 1640.
