DUIFFOPRUGCAR, Gaspar, Bologna. This famous maker of Viols is said to have settled in Bologna in the early part of the sixteenth century. He appears to have obtained much renown as an inlayer of musical instruments, and it is stated that Francis I., upon the occasion of his visit to Italy in 1515, prevailed upon the Viol-maker to settle in France. The name of Duiffoprugcar has been made familiar to us, not so much on account of his merits as a Viol-maker, but almost wholly on account of his having been represented as the first maker of the Violin tuned in fifths, and the representation having been supported by the production of three Violins signed and dated 1511, 1517, 1519. I saw, about the year 1877, one of these, and was informed by the owner that the others were almost identical. The instrument bore distinct evidence of its being a modern French imitation, or rather an ingenious creation evolved from a myth, which in all probability had its origin in France. Duiffoprugcar was unquestionably an artist of a high order, but his abilities appear to have been chiefly directed to the art of wood-inlaying, rather than to the making of stringed instruments. He made Viols da Gamba, and he may have made smaller Viols, though I am not aware of any being in existence; but there is no evidence whatever to show that he made Violins. FARINATO, Paolo, Venice, 1695-1725. FICKER, Johann Christian, Cremona, middle of the 18th century. Although dating from Cremona, has nothing in common with Cremonese work. FICKER, Johann Gottlieb, Cremona, 1788. FIORILLO, Giovanni, Ferrara, 1780. The style is a mixture of German and Italian, the former preponderating. The sound-hole is an imitation of that of Stainer. His Violoncellos are among his best instruments. FIORINO, Fiorenzi, Bologna, about 1685. FREI, Hans, Bologna, 1597. Lute and Viol-maker. There is an instrument of this make at the Bologna Academy of Music. It is probable there was a family connection between Hans Frey, of Nuremberg, and this maker. GABRIELLI, Giovanni Battista, Florence, about the middle of the 18th century. Gio Battista Gabrielli, fece in Firenze, 17-- Johanes Baptista de Gabriellis, Florentinus fecit 1742. The instruments of Gabrielli are now becoming better known and appreciated. They bear evident marks of having been made with extreme care. The model, unfortunately, is often not all that could be desired, being too rounded. When this is not the case, the tone is excellent. The wood is mostly very handsome, and the sides and backs evenly marked. The varnish is wanting in mellowness, but is very transparent; its colour is chiefly yellow. The Tenors and Violoncellos are superior to the Violins. The scroll is neatly cut, but weak in design. The letters G. B. G. were often branded on the instruments of Gabrielli. GABRIELLI. Other makers of this name (Antonio, Bartolommeo, Cristoforo) appear to have dated from Florence.
