Anselmo Bellosio was born into a family of organ makers in 1743 and moved to Venice at the age of nineteen or twenty. He began working as a violin maker in 1770, probably in the workshop of Giorgio Serafin, and he took over Serafin’s business in 1777. Many of his instruments bear original labels dated as early as 1754, but these were obviously back-dated, possibly for tax reasons. The viola made circa 1780 bears an original label dated 1762.
Bellosio’s work is rare but skillfully executed and beautifully finished, and he is considered the last of the eminent Venetian makers. To quote Charles Beare, “the great 18th century Venetian school of violin making can be said to have died out in his shop under the clock tower in Piazza San Marco.” Bellosio died of pneumonia at the age of 50. His most notable pupil was Marco Antonio Cerin, whose best work bears a striking resemblance to that of his master.
