The Sumerians wrote many mythical and epic texts dealing with creation issues, the emergence of the world, the gods, descriptions of the heavens, and the lives of heroes in the wars that broke out between the nomads and the urbanites. They also deal with religious teachings, moral advice, astrology, legislation, and history. In this same line Akkadian literature also proceeded, so that the two languages converged, and sometimes they shared the same subject.[1]
