Each form of the sacrosanct was regarded by members of the culture which gave rise to it as a revelation of the Truth; at Byzantium it was not a mere hypothesis that was sponsored by the majesty of the Byzantine style. To us, however, these forms make their appeal as forms alone - in other words, as they would be were they the work of a contemporary (and, since this actually is unthinkable, they affect us in a puzzling manner); or else as so many grandiose vestiges of a faith that has died out. We look at them from outside; they are still emotive, but they are no longer true. Thus we deprive them of what was their most vital element; for a religious civilization that regarded what it revered as a mere hypothesis is inconceivable.
