a thousand years that I need tarry beyond the frontier which after all is a frontier of my own choosing. And I shall always welcome my ancient brother on a return visit of at least the same length. If I claim to walk lightly at his side through the ages between the first Olympiad and the great Teutonic invasion of Gaul, I bid him walk more steadily, more abidingly, at my side through the ages between the Teutonic invasion of Gaul and the Ottoman conquest of Trebizond. In my next academic year I shall not need to ask leave to play truant even for so short a space as I have spoken of. My main subject will then lie fully within the barrier. We shall cross the Rhine and the Channel with the Vandal and the Saxon of the fifth century. And if it may still be sometimes needful to look back to Arminius and Ariovistus, to remember that men of our own stock fought against Gaius Julius and Gaius Marius, we can in return again call on our elder brethren to look forward for a far longer space, to assure them that we hold them thoroughly at home, not only in the Rome, Western or Eastern, of any age, but in the Aquæ Grani of Frankish Cæsars and in the Jerusalem of Lotharingian Kings. * * * * * There is one truth which in one sense I need not set forth again--it has been my lot to set it forth so often--but which I must none the less set forth almost every time that I open my mouth among you, for it must be the groundwork of my whole teaching, as it is the groundwork of all sound historic teaching. This is the truth that the centre of our studies, the goal of our thoughts, the point to which all paths lead and the point from which all paths start again, is to be found in Rome and her abiding power. It is, as I said the first time I came before you, one of the greatest of the evils which spring from our artificial distinctions where there are no distinctions in nature, from our formal barriers where there are no barriers in fact, that this greatest and simplest of historic truths is thereby wholly overshadowed. He who ends his work in 476 and he who begins his work in 476 can neither of them ever understand in its fulness the abiding life of Rome, neither can fully grasp the depth and power of that truest of proverbial sayings which speaks of Rome as the Eternal City. And none but those who have thoroughly grasped the place of Rome in the history of the world can ever fully understand the most notable historic feature of the age in which we ourselves live. We live in an age from which Rome has passed away, an age at least in which Rome has lost her headship. And, by one of the wonderful cycles of history, the Romeless world from which Rome has passed away is in not a few points a return to the elder Romeless world on which Rome had not yet risen. In both alike the European world lacks a centre; in both alike, each city or nation does what is right in its own eyes, without even the theory of a controlling power. The fuller
