Night, (Edipus and Creon, and the Italian Parnassus. By command of Prince Eugene, viceroy of Italy, Bossi undertook to make a copy of the Last Supper of Leonardo, then almost obliterated, for the purpose of getting it rendered in mosaic. The drawing was made from the remains of the original with the aid of copies and the best prints. The mosaic was executed by Raffaelli, and was placed in the Imperial Gallery of Vienna. Bossi made another copy in oil, which was placed in the museum of Brera. This museum owed to him a fine collection of casts of great works of sculpture acquired at Paris, Rome, and Florence. Bossi devoted a large part of his life to the study of the works of Leonardo; and his last work was a series of drawings in monochrome representing incidents in the life of that great master. He left unfinished a large cartoon in black chalk of the Dead Christ in the bosom of Mary, with John and the Magdalene. In 1810 he published a special work in large quarto, entitled Del Cenacolo di Leonardo da Vinci, which had the merit of greatly interesting Goethe. His other works are Delie Opinioni di Leonardo intorno alia simmetria de' corpi umani (1811), and Del Tipodell' arte della pittura (1816). Bossi died at Milan, December 15, 1816. A monument by Canova was erected to his memory in the Ambrosian library, and a bust was placed in the Brera.

BOSSI, Giuseppe Carlo Aurelio, Baron de, an Italian poet and diplomatist, was born at Turin, November 15, 1758. He made his first appearance as poet at the age of eighteen by the publication of two tragedies, Lea Silvia and I C ir cassi ; and four years later he took the degree of doctor of laws. In 1781, in consequence of his ode in praise of the edict of toleration promulgated by the Emperor Joseph IL, he was banished the kingdom; but having rendered during his exile an important service to his countrymen he was recalled and appointed undersecretary of state for foreign affairs. In 1792, on occasion of the French invasion, he was sent to the court of Prussia to negotiate an alliance, and thence went as ambassador to St Petersburg. Dismissed by the emperor in consequence of the treaty of alliance between Sardinia and France (1797), he was named ambassador to Venice, which he reached only in time to witness the fall of the republic. He was next appointed envoy to General Bonaparte in Italy. After the conquest of Sardinia Bossi was a member of the Provisional Government, and one of the three deputies sent to Paris to petition for annexation to France. The Russian invasion of 1799 drove him to take refuge in the Vaudois valleys. He was afterwards a member of the Provisional. Government, but retired in 1802. Three years later he was made prefect of the Ain; he was created baron by Napoleon I. in 1810, and was afterwards transferred to the prefecture of La Manche. Deprived on the second return of the Bourbons, he came to England, but returned to France the following year. He spent his remaining years in retirement. Besides the works above mentioned Bossi was author of a long poem entitled Oromasia, on the events of the French revolution; Monaca, a poem on the secularization of convents (1787); and various lyrical pieces, among which are Independenza Americana (1785), 0landa Pacificata (1788), Vision (1799), &c. He died at Paris, January 20, 1823.
