I must note also the important influence on literature exercised by Alexander the Great; for while his travels encouraged the more accurate research of geography, the very splendour of his achievements seems to have brought history again into the sphere of romance. The appearance of all great men in the world is followed invariably by the rise of that mythopoeic spirit and that tendency to look for the marvellous, which is so fatal to true historical criticism. An Alexander, a Napoleon, a Francis of Assisi and a Mahomet are thought to be outside the limiting conditions of rational law, just as comets were supposed to be not very long ago. While the founding of that city of Alexandria, in which Western and Eastern thought met with such strange result to both, diverted the critical tendencies of the Greek spirit into questions of grammar, philology and the like, the narrow, artificial atmosphere of that University town (as we may call it) was fatal to the development of that independent and speculative spirit of research which strikes out new methods of inquiry, of which historical criticism is one. The Alexandrines combined a great love of learning with an ignorance of the true principles of research, an enthusiastic spirit for accumulating materials with a wonderful incapacity to use them. Not among the hot sands of Egypt, or the Sophists of Athens, but from the very heart of Greece rises the man of genius on whose influence in the evolution of the philosophy of history I have a short time ago dwelt. Born in the serene and pure air of the clear uplands of Arcadia, Polybius may be said to reproduce in his work the character of the place which gave him birth. For, of all the historians--I do not say of antiquity but of all time--none is more rationalistic than he, none more free from any belief in the 'visions and omens, the monstrous legends, the grovelling superstitions and unmanly craving for the supernatural' ([Greek] {197a}) which he is compelled to notice himself as the characteristics of some of the historians who preceded him. Fortunate in the land which bore him, he was no less blessed in the wondrous time of his birth. For, representing in himself the spiritual supremacy of the Greek intellect and allied in bonds of chivalrous friendship to the world-conqueror of his day, he seems led as it were by the hand of Fate 'to comprehend,' as has been said, 'more clearly than the Romans themselves the historical position of Rome,' and to discern with greater insight than all other men could those two great resultants of ancient civilisation, the material empire of the city of the seven hills, and the intellectual sovereignty of Hellas.
