The period before the deluge was the one of revelation in the Mesopotamian mythology, when the basis of all later knowledge was laid down. The antediluvian sages were culture-heroes, who brought the arts of civilization to the land. During the time that follows this period, nothing new is invented, the original revelation is only transmitted and unfolded. Oannes and other sages taught all fundations of civilization to antediluvian mankind.
