"Research into the Black Madonna phenomenon is limited due to a wide consensus among scholars that the dark-skinned aspect was unintentional." something in art, something on the outskirts of mainstream religion, found across *many* instances -- unintentional? the silliest thing I've read in some time now! it may be metaphorical & symbolic, or it may be literal, or (most definitely) it may vary across the cities and centuries, but it sure is intentional. and that outskirts/ outsider thing -- yea, you bet it is addressing an otherwise-unfulfilled need of the community.
