The opportuneness of this warning is confirmed by the astonishment of those who consider the passage from ancient to Christian or medieval historiography; for what can be the meaning of this passage, in which we find ourselves faced with a miraculous and mythological world all over again, identical as it seems, in its general characteristics, with that of the ancient historians, which has disappeared? It is certainly not progress, but rather falling into a ditch, into which also fall all the dearest illusions relating to the perpetual advance of humanity. And the Middle Ages did seem to be a ditch or a declivity, sometimes during the period itself and most clearly at the Renaissance, and this image is still represented in common belief. Restricting ourselves solely to the domain of historiography, and following up the impression of astonishment at first caused by it, we end by representing events at the beginning of the Middle Ages somewhat in the way they appeared to our writer Adolfo Bartoli, in his introductory volume to the _History of Italian Literature,_ which is all broken up with cries of horror and with the gesture of covering the face lest he should see so much ugliness. "We are in a world," writes Bartoli, when speaking of Gregory of Tours, "where thought has descended so low as to cause pity, in a world where a conception of history no longer exists," and history also becomes "a humble handmaid to theology--that is to say, an aberration of the spirit." And after Gregory of Tours (continues Bartoli) there is a further fall: "Behold Fredigarius, in whom credulity, ignorance, and confusion surpass every limit... there survives in him nothing of a previous civilization." After Fredigarius, with the monastic chronicle, we take another step down-ward toward nothingness, though this would seem to be impossible. Here "we seem to see the lean monk putting his trembling head out of the narrow window of his cell every five or eleven years, to make sure that men are not all dead, and then shutting himself up again in the prison, where he lives only in the expectation of death." We must protest against such shrinking back (which makes the critic of to-day look like the "lean monk" whose appearance he has so vividly portrayed); we must assert that mythology and miracle and transcendency certainly returned in the Middle Ages--that is to say, that these ideal categories again acted with almost equal force and that they almost reassumed their ancient bulk, but they did not return _historically identical_ with those of the pre-Hellenic world. We must seek in the heart of their new manifestations for the effective progress which is certainly accomplished by Gregory of Tours and Fredigarius, and even by the monkish chroniclers.
