Such a people could offer no resistance to the steadily-increasing tyranny of the Eastern Empire.

In vain did such men as Chrysostom and Basil oppose their personal influence to the hideous intrigues and villainies of the Byzantine court; the ever-downward career of Eastern Christianity went on unchecked for two more miserable centuries, side by side with the upward development of the Western Church; and, while the successors of the great Saint Gregory were converting and civilising a new-born Europe, the Churches of the East were vanishing before Mohammedan invaders, strong by living trust in that living God, whom the Christians, while they hated and persecuted each other for arguments about Him, were denying and blaspheming in every action of their lives.
But at the period whereof this story treats, the Graeco-Eastern mind was still in the middle of its great work.

That wonderful metaphysic subtlety, which, in phrases and definitions too often unmeaning to our grosser intellect, saw the symbols of the most important spiritual realities, and felt that on the distinction between homoousios and homoiousios might hang the solution of the whole problem of humanity, was set to battle in Alexandria, the ancient stronghold of Greek philosophy, with the effete remains of the very scientific thought to which it owed its extraordinary culture.

Monastic isolation from family and national duties especially fitted the fathers of that period for the task, by giving them leisure, if nothing else, to face questions with a lifelong earnestness impossible to the more social and practical Northern mind.

Our duty is, instead of sneering at them as pedantic dreamers, to thank Heaven that men were found, just at the time when they were wanted, to do for us what we could never have done for ourselves; to leave to us, as a precious heirloom, bought most truly with the lifeblood of their race, a metaphysic at once Christian and scientific, every attempt to improve on which has hitherto been found a failure; and to battle victoriously with that strange brood of theoretic monsters begotten by effete Greek philosophy upon Egyptian symbolism, Chaldee astrology, Parsee dualism, Brahminic spiritualism-graceful and gorgeous phantoms, whereof somewhat more will be said in the coming chapters.
I have, in my sketch of Hypatia and her fate, closely followed authentic history, especially Socrates' account of the closing scene, as given in Book vii.
