I can't remember exactly where I read it, but I suspect it was either in David Van Edwards "Build your own Renaissance Lute" CD course, or "Historical Lute Construction" by Robert Lundberg, that the lack of lining between the soundboard and ribs is to keep the top as light and flexible as possible, and to make it easier to remove the top in the future for repair. In fact the overall construction philosophy of lutes, vihuelas, viols, Renaissance and Baroque guitars, seems to be light. As far as the backs are concerned, I suppose it was also in keeping with the light philosophy and if these instruments didn't suffer catastrophic failure due to inadequate glue surface between the back and sides under normal use, then linings aren't really needed. Modern guitars are built much more heavily than their ancestors.

Whenever I see constructional details of flat-backed plucked instruments after about 1800 or so they all seem to use either solid linings, or kerfing or tentallones to join the top and the back to the sides. This is true (I think) of all guitars, flat-backed mandolins, ukuleles bandurrias, timples... etc....they all use extra wood attached to the insides of the ribs. But at least some earlier (flat-backed, plucked) instruments don't. Have I got that right? If so, why do (some) earlier instruments just have soundboard and backs glued to the sides?
