The possible adhesive materials available during the middle ages were most likely animal protein (think gelatin) or hydrating minerals. The latter would be my choice. Like concrete the presence of water (high humidity in the cathedral) would help with the long term hydration process. I'm less inclined to think polymerization of animal protein because of the degradation over long periods of time, and a lot of adhesive candidates may be hydrophilic--but, the water cleaves the bonds eventually. Then, like Jeff suggests, if the artwork had to be redrafted in place, some sort of tacky-adhesive must have been in play. Has anyone followed up with the Vatican?

Maybe we're looking agt adhesion the wrong way, especially for non-glossy micromosaics. What if, instead of applying glue and setting each individual tessera into it, you laid them on a surface just taky enough to hold them in place while you were doing the arranging, and then sprayed a colour-neutral adhesive solution over them? Especially if you'd found a pair of adhesives (tacky short-term backing plus coating in place) that stuck even more firmly together? I don't know if that was the Vatican's (or anybody else's) solution, but I'll bet it could work…
