"The year 1713 gives us an admirable violin, the "Boissier," now owned by Senior Sarasate. Fetis mentions it as one of the finest existing Stradivaris, and we can certainly confirm his statement. Its outline is of the 14 and 1/16 inch form, the model a little fuller, though closely following that of the "Parke" instrument; the edge, corners, and purfling are perhaps a trifle neater, and the sound-holes more lightly cut. The varnish is also of great beauty, its tint being a shade redder than that of the "Parke," and the whole instrument is in very fine condition."
