Such are the new problems and the new solutions which Christianity brought to historical thought, and it may be said of them, as of the political and humanistic thought of the ancients, that they constitute a solid possession of perpetual efficacy for the human spirit. Eusebius of Cæsarea is to be placed beside Herodotus as 'father' of modern historiography, however little disposed it may be to recognize its parents in that barbaric author and in the others who were called 'fathers of the Church,' to whom, and particularly to St Augustine, it yet owes so great a part of itself. What are our histories of culture, of civilization, of progress, of humanity, of truth, save the form of ecclesiastical history in harmony with our times--that is to say, of the triumph and propagation of the faith, of the strife against the powers of darkness, of the successive treatments of the new evangel, or good news, made afresh with each succeeding epoch? Do not the modern histories, which narrate the function performed or the pre-eminence assumed by this or that nation in the work of civilization, correspond to the _Gesta Dei per Francos_ and to other like formulas of medieval historiography? And our universal histories are such not only in the sense of Polybius, but also of the universal as ideal, purified and elevated in the Christian sense; hence the religious sentiment which we experience on approaching the solemnity of history. It will be observed that in presenting it in this way we to some extent idealize the Christian conception; and this is true, but in the same way and in the same measure as we have idealized ancient humanism, which was not only humanism, but also transcendency and mystery. Christian historiography, like ancient historiography, solved the problems that were set to it, but it did not solve other problems that were only formed afterward, because they were not set to it. A proof of this is to be found in the caprices and the myths that accompanied its fundamental conception. The prodigious and the miraculous, which, as already observed, surrounded Christian historiography, bore witness precisely to the incomplete ideality of the new and loftier God, the thought of whom became converted into a myth, his action into fabulous anecdotes. Yet when it was not a question of miracles, or when these were reduced to small compass, attenuated and held back, if not refuted, there nevertheless remained the miracle of the divinity and of the truth, conceived as transcendent, separated from and opposed to human affairs. This too was an attestation of the Christian spirit, in so far as it surpassed the ancient spirit, not with the calmness and security of thought, but with the violence of sentiment and with the enthusiasm of the imagination. Transcendency led to a consideration of worldly things as external and rebellious to divine things: hence the dualism of God and the world, of a _civitas colestis_ and of another
