Why the f-hole?

The violin was created in northern Italy, and from its initial emergence in the sixteenth century, the sound hole was in the shape of an "f." Why was this shape chosen? There is as yet no reasonable explanation. However, if the shape or size is changed, it has a dramatic effect on the tone of the instrument. In addition, the cross of the "f" shape marks the position of the bridge and the sound post. The inside and outside marks are at different locations, and the standard position is exactly between these two marks. At the very least, this is an argument against the use of the S-hole.
