pupil of Anaxagoras, seems to be of the same opinion concerning the first generation of all things, for in his _Menilippe_ he has these verses: “‘A mass confused Heaven and Earth once were Of one form; but after separation Then men, trees, beasts of the earth with fowls of the air First sprang up in a generation.’ “But if this power of the earth to produce living creatures at the first origin of all things seem incredible to any, the Egyptians bring testimonies of this energy of the earth by the same things done there at this day; for they say that about Thebes in Egypt, after the overflowing of the river Nile, the earth thereby being covered by mud and slime, many places putrefy by the heat of the sun, and thence are bred multitudes of mice. It is certain, therefore, that out of the earth when it is hardened, and the air changed from its dew and natural temperament, animals are generated, by which means it came to pass that in the first beginning of all things various living creatures proceeded from the earth. And these are the opinions touching the original of all things.” It would be difficult to say to what extent this Greek conception of creation had its origin in, or was influenced by, Oriental conception. Certainly the resemblance between this description and the Mosaic accounts, as contained in the first two chapters of Genesis, is noteworthy. Quite probably the ideas of both Hebrews and Greeks had been moulded to some extent in the pattern of Egyptian thought. Be that as it may, it was the scheme of cosmogony expressed in the Hebrew legends that was to become dominant in post-classical times, and to rule unchallenged in the Western world for more than a thousand years. Indeed, this estimate of the time of real supremacy of the Hebrew thought is much too low; for that thought, though challenged as to some of its features by the science of the Renaissance which ushered in the period of modern history, was none the less to retain its hold upon the thoughts of men, but little abated in force, for another half millennium.
