> Limestone is soft and porous and will never glisten the way marble does. It was polished fine limestone, though. Maybe it wouldn't have had the same optical qualities as polished marble, but it could [in theory] easily have been incredibly bright with a high reflectance. Modern polished limestone can have a strong gloss almost indistinguishable from polished marble, but maybe that's from modern sealants, polishers, or power tools?
