Life Imitating Architecture
Christianity was turning outward and visible things inwards. The basilicas built in Rome by the Emperor Constantine, after his conversion in 312, gave architectural expression to the difference of focus between paganism and the new moral beliefs. In place of the ancient temple, with its splendid columns and decorations on the exterior, the Christian basilica was simple, unadorned brick on the outside, with columns and decorations reserved for the interior. The change was symptomatic. Where paganism had concerned itself primarily with external conformity of behaviour, Christianity now concerned itself especially with inner conviction.
Never noticed that.
