Sumerian mythology was the denomination which was functioned and adhered to by the Sumerian population, the first scholarly civilization of classical Mesopotamia. The Sumerians observed their deities as accountable for all concerns about the physical and social systems. Sumerian temples were simplistic, one-room arrangements, sometimes mounted on raised stages. Towards the conclusion of Sumerian civilization, these stupas progressed into ziggurats—high, pyramidal buildings with sanctums at the tops.
