(1758–1823). Italian painter. He is best known as a decorative painter in the neoclassical style. After training with Batoni at the Accademia di S. Luca in Rome he went on to design decorations for Catherine II of Russia (1788) and to contribute to schemes at the Tuileries Palace in Paris for Napoleon (c. 1800–9). His most important work was fresco decoration in the Palazzo Milzetti at Faenza. Giani was also a fine draughtsman in a style reminiscent of Fuseli.
