In Mesopotamian mythology, gods like Anu represent the sky, while Greek mythology features the Titanides, celestial beings like Helios, signifying the sun and its life-giving properties. These stories highlight the strong connection between the divine and the cosmos, shaping rituals and cultural understanding of the universe's workings.
