Mark off on the scale A B as many divisions as there are lbs. in the tension of a string, for example 18, and from that point draw a line parallel to B D, cutting A D at the point 8 in that scale. Then, if the tension of a string be 18 lb., the downward pressure on the bridge will be 8 lb.; and therefore for the above angle the downward pressure of any string on the bridge will be 8/18=4/9 of the tension of that string.
The whole of the downward pressure of the first string falls upon the Treble Foot of the Bridge.
The downward pressure of the second string is about 2/3 the Treble Foot of the Bridge, and 1/3 on the Bass Foot.
The downward pressure of the third string is about 1/3 on the Treble Foot, and 2/3 on the Bass Foot.
The whole of the downward pressure of the fourth string falls upon the Bass Foot of the Bridge.
SECTION IV
The Italian School
The fifteenth century may be considered as the period when the art of making instruments of the Viol class took root in Italy, a period rich in men labouring in the cause of Art. The long list of honoured names connected with Art in Italy during the fifteenth, sixteenth, and seventeenth centuries is a mighty roll-call indeed! The memory dwells upon the number of richly-stored minds that have, within the limits of these three centuries, bequeathed their art treasures to all time; and if here we cannot suppress a comparison of the art world of the present Italy with that of the periods named, still less can we fail to be astonished as we discover the abyss into which Italy must be judged to have sunk in point of merit, when measured by the high standard which in former days she set herself. But perhaps the greatest marvel of all is the rapidity of the decadence when it once set in, as it did immediately after the culminating point of artistic fame had been reached.
