Bartolomeo Nazari (May 31, 1693 - August 24, 1758) was an Italian painter of the late-Baroque, mainly active in Venice as a portraitist. Born in Clusone, near Bergamo. By 1716, he had become an apprentice under Angelo Trevisani, but visited in 1723 the Roman studio of Angelo's brother, the Venetian Francesco Trevisani, and then also studied with Benedetto Luti. Nazari likely knew personally Fra Galgario, the renowned portraitist from Bergamo, and is described by some as a pupil. He returns to Venice in 1724, and is registered with the Fraglia dei Pittori by 1726. In 1744, he traveled to Frankfurt to paint the emperor Charles VII and his family and other members of the court. In 1756, he was inducted into the newly founded Accademia of Venice. His son Nazario Nazari was also a painter. Among his patrons was Consul Joseph Smith and the former general Johann Matthias von der Schulenburg (who owned over eight diverse portrait paintings). He painted the portraits of a number of operatic singers including Farinelli. He died returning from Genoa, where he had painted the Doge.
