Aether or
Aither (
Æthere, , ), in
ancient Greece, was one of the
primordial deities. Aether is the personification of the upper air. He embodies the pure upper air that the gods breathe, as opposed to the normal air (, ) breathed by mortals. Like
Tartarus and
Erebus, Aether may have had shrines in ancient Greece, but he had no temples and it is unlikely that he had a cult.
