Such queer humors and droll comparisons flash into the mind of Reuben, even under all his sense of awe,--a swift, disorderly mingling of the themes and offices which kindled his first sense of religious awe under a home atmosphere with the wondrous forms and splendor which kindle a new awe now. The great dome enwalling with glittering mosaics a heaven of its own, and blazing with figured saints, and the golden distich, "Thou art Peter,--to thee will I give the keys of the kingdom of heaven,"--all this seems too grand to be untrue. Are not the keys verily here? Can falsehood build up so august a lie? A couple of friars shuffle past him, and go to their prayers at some near altar; he does not even smile at their shaven pates and their dowdy, coarse gowns of serge. Low music from some far-away chapel comes floating under the panelled vaultings, and loses itself under the great dome, with a sound so gentle, so full of entreaty, that it seems to him the dove on the high altar might have made it with a cooing and a flutter of her white wings. A mother and two daughters, in black, glide past him, and drop upon their knees before some saintly shrine, and murmur their thanksgivings, or their entreaty. And he, with no aim of worship, yet somehow shocked out of his unbelief by the very material influences around him. Reuben's old wranglings and struggles with doubt had ended--where so many are apt to end, when the world is sunny and success weaves its silken meshes for the disport of self--in a quiet disbelief that angered him no longer, because he had given over all fight with it. But the great dome, flaming with its letters, _AEdificabo meam Ecclesiam_, shining there for ages, kindled the fight anew. And strange as it may seem, and perplexing as it was to the Doctor (when he received Reuben's story of it), he came out from his first visit to the great Romish temple with his religious nature more deeply stirred than it had been for years. _AEdificabo meam Ecclesiam._ _HE_ had uttered it. There was then something to build,--something that had been built, at whose shrine millions worshipped trustingly. Under the sombre vaultings of the great Florentine Cathedral, the impression was not weakened. The austere gloom of it chimed more nearly with his state of unrest. Then there are the galleries, the painted ceilings,--angels, saints, martyrs, holy families,--can art have been leashed through so many ages with a pleasant fiction? Is there not somewhere at bottom an earnest, vital truth, which men must needs cling by if they be healthful and earnest themselves? Even the meretricious adornments of the churches of Genoa afford new evidence of the way in which the heart of a people has lavished itself upon belief; and if belief, why, then, hope.
