Following the stories of Afro Brazilian origin, I interpreted in this way the divinity called Oxumare.
The rainbow serpent represents the junction between male and female, a union that makes the existence of life possible, that allow water and land, mortality and immortality, the ambiguous and opposites, and everything that is double to complement each other.
It is a large snake that wraps the Earth with its tail and ensures the integration of the planet and the renewal of the universe governing its transformations. Art transforms man, transforms his soul and his understanding of the world.
