Sun gods, such as Ra in Egyptian mythology or Helios in Greek, often embody power and authority, governing natural cycles and influencing agriculture. These deities are associated with qualities like strength, nurturance, and eternity, reflecting the sun’s essential role in sustaining life. Their narratives often explore themes of creation, renewal, and the relationship between the divine and nature.
