A drawing by Jacopo Ligozzi (Italian 1547-1627), one of the most remarkable artists of the Medici court, is on public view in New York for the first time at Christopher Bishop Fine Art (1046 Madison Avenue at 80th Street) and has been extended through March 31. Ligozzi’s The Contest of Pan and Apollo, c. 1585, presents a musical competition between two gods. An idealized representation of the Golden Age, Ligozzi’s drawing was intended to bring not only prestige but power to his principal patrons, the Medici family of Florence.
