Adolphe Didron, in his book Christian Iconography, states what happened: “The figure of Christ, which had at first been youthful, becomes older from century to century... as the age of Christianity itself progresses. ”
Adolphe Didron valgustab seda arengut oma raamatus ” Christian Iconography ”: ” Kristuse esialgu nooruke kuju muutub sajandist sajandisse vanemaks,.. nii nagu kristlusele endalegi vanust lisandub. ”
