Mboi Tu’i is a term from the Guarani language, primarily spoken in Paraguay, which translates to "snake of the sky" or "celestial serpent." In Guarani mythology, the Mboi Tu’i is a significant cultural symbol representing a powerful and benevolent serpent associated with the sky and water. The term "Mboi" (מבווי) means "snake" or "serpent," and "Tu’i" (טוי) refers to the sky or heavens. This mythological creature is often depicted as a guardian of knowledge and wisdom, embodying the connection between the earthly and celestial realms. The Mboi Tu’i is also linked to the creation stories of the Guarani people, where it plays a role in shaping the natural world. In broader indigenous South American contexts, similar serpent deities appear in various mythologies, reflecting a shared cultural significance of serpents as symbols of power and transformation.
