The theorizing priests, who speculated regarding the mysteries of life and death and the origin of all things, had to address the people through the medium of popular beliefs. They utilized floating myths for this purpose. As there were in early times various centres of culture which had rival pantheons, the adapted myths varied greatly. In the different forms in which they survive to us they reflect, not only aspects of local beliefs, but also grades of culture at different periods. We must not expect, however, to find that the latest form of a myth was the highest and most profound. The history of Babylonian religion is divided into periods of growth and periods of decadence. The influence of domestic religion was invariably opposed to the new and high doctrines which emanated from the priesthood, and in times of political upheaval tended to submerge them in the debris of immemorial beliefs and customs. The retrogressive tendencies of the masses were invariably reinforced by the periodic invasions of aliens who had no respect for official deities and temple creeds. We must avoid insisting too strongly on the application of the evolution theory to the religious phenomena of a country like Babylonia. The epochs in the intellectual life of an ancient people are not comparable to geological epochs, for instance, because the forces at work were directed by human wills, whether in the interests of progress or otherwise. The battle of creeds has ever been a battle of minds. It should be recognized, therefore, that the human element bulks as prominently in the drama of Babylon's religious history as does the prince of Denmark in the play of _Hamlet_. We are not concerned with the plot alone. The characters must also receive attention. Their aspirations and triumphs, their prejudices and blunders, were the billowy forces which shaped the shoreland of the story and made history. Various aspects of Babylonian life and culture are dealt with throughout this volume, and it is shown that the growth of science and art was stimulated by unwholesome and crude superstitions. Many rank weeds flourished beside the brightest blossoms of the human intellect that wooed the sun in that fertile valley of rivers. As in Egypt, civilization made progress when wealth was accumulated in sufficient abundance to permit of a leisured class devoting time to study and research. The endowed priests, who performed temple ceremonies, were the teachers of the people and the patrons of culture. We may think little of their religious beliefs, regarding which after all we have only a superficial knowledge, for we have yet discovered little more than the fragments of the shell which held the pearl, the faded petals that were once a rose, but we must recognize that they provided inspiration for the artists and sculptors whose achievements compel our wonder and admiration, moved statesmen to inaugurate and administer humanitarian laws, and exalted Right above Might.
