So a mirror, over an altar or elsewhere but anyhow in some artistic context, becomes a meeting point of the human mirroring and reflecting phenomenon and the universal reality that that the mirror itself is able to reflect. A mirror is a way between the visible and the invisible, as it extends sight beyond its seemingly normal faculties. Mirrors, in a room or over an altar, widen the characteristics of the eye and the faculties of the mind so that it offers a vision of totality. I think that there is only on mirror, divided and multiplied, in every available mirror in the world.
