This illustration of a Joseph Rocca violin was published in The Strad, May 1938. The following text is extracted from the article accompanying the photographs:

Guiseppe Antonio Rocca, born in Turin in about 1810, was essentially a copyist; firstly of the Stradivarius model, especially the ‘Messie’, and of Guarneri, also according to some Maggini. Like Pressenda, with whom he worked, Rocca exhibits a decided preference for whole backs cut on the quarter and his material is almost always finely figured.

The example illustrated is a fine specimen of the maker’s Stradivarius copies in a wonderful state of preservation. Rocca violins have found increasing favour among soloists and orchestral leaders for their excellent tonal qualities.

His varnish entitles him to a high place amongst the last of the great Italian makers. In this feature he exhibits considerable variety both in colour and texture. The violin illustrated is a golden brown. Although the varnish has been generously applied it is very transparent and enhances the beauty of the handsome wood beneath.

The principal measurements are: Length, 14 inches; Stop, 13 inches; Upper Bouts, 6 5/8 inches; Lower Bouts, 8 1/8 inches full.
