About Aether Primordial
Aether (also Æther, Greek: Αἰθήρ), in Greek mythology, is one of the Protogenoi, the first-born elemental gods. He is the personification of the "upper sky," space, and heaven, and the elemental god of the "Bright, Glowing, Upper Air." He is the pure upper air that the gods breathe, as opposed to normal air (Ἀήρ, aer), the gloomy lower air of the Earth, which mortals breathe.
In Hesiod's Theogony, he was the son of Erebus and Nyx and brother of Hemera, both noted in passing in Cicero's De Natura deorum, but Hyginus Pref mentioned Khaos as his parent. The aether was also known as Zeus' defensive wall; the bound that locked Tartarus from the rest of the cosmos.
He has several offspring but Hyginus seems to confuse him with Ouranos when saying that Aether had Uranus by Gaia, his daughter. Aergia, a goddess of sloth and laziness, is the daughter of Aether and Gaia. Hyginus is also our source for telling us that Aether is the father of Ouranos and Gaia. But another source tells us that it is just Ouranos who is his child. And like Tartaros and Erebos, in Hellas he might have had shrines but no temples and probably no cult either. In the Orphic hymns, he is mentioned as the soul of the world from which all life emanates. Callimachus, in calling Ouranus Akmonides, claims him as the son of Akmon, and Eustathius in Alcman tells us that the sons of Ouranos were called Akmonidai.
