Caelus

Caelus or Coelus was a primal god of the sky in Roman myth and theology, iconography, and literature (compare caelum, the Latin word for "sky" or "the Heaven", hence English "celestial"). The deity's name usually appears in masculine grammatical form when he is conceived of as a male generative force, but the neuter form Caelum is also found as a divine personification. Also known as Uranus in both Greek and Roman mythologies.
