Enki is the Sumerian god of water, knowledge , mischief, and creation. Later known as Ea in Akkadian and Babylonian. He was originally patron god of the city of Eridu, but later the influence of his cult spread throughout Mesopotamia and to the Canaanites, Hittites and Hurrians. He was associated with the southern band of constellations called stars of Ea, but also with the constellation AŠ-IKU, the Field (Square of Pegasus). Beginning around the second millennium BCE, he sometimes gets referred to in writing by the numeric ideogram for “40“, occasionally referred to as his “sacred number“.
