The duality of light and dark characters in mythology explores the balance between good and evil, knowledge and ignorance. Light is often associated with hope, wisdom, and divinity, represented by figures like the Greek god Apollo, while darkness embodies chaos, confusion, or evil, often personified by deities like Hades. This interplay reflects the human struggle to navigate moral complexities and the eternal quest for understanding and enlightenment. Various cultures use these contrasts to symbolize the dual nature of existence, illustrating that light and darkness coexist within each individual, shaping their journey and choices.
