Caelus

Caelus or Coelus was a god of the sky in Roman myth and theology and literature. Its name usually appears in masculine form when he is thought of as a male generative force.

According to Cicero and Hyginus, Caelus was the son of Aether and Dies ("Day" or "Daylight").^[1] Caelus and Dies were in this tradition the parents of Mercury.^[2]
