The term "vault of heaven" is a metaphorical expression used to depict the celestial sphere or the entire expanse of the sky visible from Earth. It is brimming with celestial bodies like stars, planets, and galaxies. In ancient times, this concept was widely believed to be an ethereal dome, a solid or semi-solid structure that encompassed the Earth.
The term "vault" refers to a curved or arched structure that resembles the shape of an archaic rooftop. The "heaven" in this context refers to the vast expanse of outer space, believed to be the dwelling place of deities or divine beings, and the ultimate significance of the afterlife.
According to this definition, the vault of heaven is the colossal dome that encloses the Earth, stretching above and around it. It encompasses all celestial bodies and seemingly infinite space, stirring questions about the mysteries of the universe and human existence.
