Included in the Simon "Necronomicon" is a story that is a variant of the Enuma Elish, the Babylonian creation epic. It relates how Marduk (Leader of the Elder Gods) slew Tiamat (Queen of the Ancient Ones), clove her body in two and created the Heaven and the Earth from the two halves. The Elder Gods also created mankind from the blood of Kingu (an Ancient One). Other Ancient Ones are imprisoned beneath the Earth or beyond the Heavens. With the exception of the terms "Elder Gods" and "Ancient Ones" (which were first popularized by the fiction of H. P. Lovecraft), many of these stories are derived from authentic myths.
