this mighty intellectual transformation was imparted by Egypt, and sprang from the historical and philosophical reminiscences of the Alexandrian Museum. That renowned institution was the unique and practical embodiment of the passion for innovation, of the inventive faculty, of the utilitarian spirit of the ancient world. The doctrines of the higher antiquity were, as is well known, largely theoretical and speculative. The occasional appearance of men of genius like Hippocrates and Aristotle only served to emphasize the worthless character of the verbose and unprofitable disquisitions of the schools of Greek philosophy. Anterior to the fourth century before Christ, science owed little to experiment, and all knowledge of any value was empirical, or the result of purely accidental discovery. No intelligent method of investigation existed. No system which had for its object the physical amelioration of humanity was deemed worthy of attention. Such practical aims were trifles and beneath the dignity of the wise man of that age. His time was occupied in attempts to explain the nature of the soul, to define the supreme good, to discover the original essence of all created things, to demonstrate the fancied harmony or dissonance of numbers. In these absurd and fruitless occupations were wasted intellectual abilities which, properly directed, might have changed the aspect of nature and the condition of society many centuries before modern inventive genius was afforded an opportunity to exhibit its marvellous powers. The shrewd and discerning soldier, who, in the partition of empire, received as his share the ancient dominion of Egypt, pursued a diametrically opposite course in the policy he adopted for the promotion of education and literature. He united the culture of Macedon and the venerable traditions of the civilization of Persia with the experience gained in many campaigns. His skeptical and arbitrary nature had little sympathy with the abject superstitions of his Egyptian subjects, and still less with the despotic pretensions of their priesthood. His position as ruler invested him with almost theocratical authority. Scarcely was he seated upon the throne before a radical change was resolved upon. The genius of Ptolemy impelled him to attempt the modification of a system, sanctified by the practice of immemorial antiquity, in such a way that its outward observance would not be repugnant to Greek intelligence nor, by the violation of long-established prejudices, the stability of the newly constituted government be endangered. To accomplish this end, the worship of Serapis, the representative of Oriental Pantheism, was introduced. This strange co-ordination of skepticism and idolatry was productive of remarkable consequences. The Egyptians admitted with enthusiasm a new god into their Pantheon. The Ptolemaic dynasty was placed upon a firm and enduring basis. In the magnificent temple where was enshrined
