This illustration of a violin by Joseph Rocca was published in The Strad, February 1973. The following text is extracted from the article accompanying the photographs:
Giuseppe Antonio Rocca, better known by the anglicised form of his name, Joseph Rocca, was born at Barbaresco, near Turin, in 1807 and died around 1868 in Genoa. He worked for several years with Giovanni Francesco Pressenda, a maker who had been taught his craft in the workshop of Lorenzo Storioni who many consider the last of the old Cremonese school.
Rocca was essentially a copyist but did not confine himself to imitating Pressenda. His fine copies of the ‘Messie’ Stradivarius are highly prized as are his rarer Guarneri del Gesu models. He is also said to have made an occasional copy of a Maggini.
The Rocca illustrated is in very fine condition. It was made at Turin in 1847 and has its original label. The letters ‘G.R.’ are branded at the end of the neck at the throat of the scroll. The one-piece back is of handsomely broad flamed maple, the flames extending downwards from left to right. The ribs match the back, also the scroll and neck. The table is of spruce with medium fine grain at the centre opening out at the flanks. The brilliant orange-brown varnish is all original.
The principal measurements of this Rocca are: Length 14 inches (full); Upper Bouts 6 11/16 inches; Middle bouts 4 9/16 inches; Lower Bouts 8 3/16 inches.
