Aether was one of the primordial deities in Greek mythology, the son of the primordial deities Erebus (darkness) and Nyx (night), or according to Orphic Hymns, Chronos (time) and Ananke (necessity). He was the brother of Hemera (day), and according to some sources, he fathered Gaea (earth), Thalassa (sea) and Uranus (heavens). He was the personification of the upper air that only gods breathe, as opposed to the normal air breathed by mortals. The air encircling the mortal world was called Chaos or Aer, while the Underworld where the dead dwelled was enveloped in Erebos, the mist of darkness.
