In the catacombs under Rome, we find artwork that is deeply phenomenologically symbolic in nature. Interestingly, it is formally similar to the sorts of artwork found in the large cathedrals built on top of it. But while the soaring cathedrals that tower over one above the surface portray an exoteric message melded with an esoteric connection to Nimrodian religions which it displaced, the subterranean artwork portrays biblical stories depicted in pure phenomenological archetype.
In a sense, this models the human experience. Our exoteric experience comes into contact with the power of civilization and the state (Nimrod). Our inner experience draws upon the pure archetypes of the vast Mass Unconscious.
As Lacan would point out, although there is some expression of form in the former which draws upon the latter, much of the essence is lost in translation between the catacomb and the cathedral.
