Aether in Greek and Roman Biography and Mythology
（Αἰθήρ), a personified idea of the mythical cosmogonies.
According to that of Hyginus (Fab. Pref. p. 1, ed. Staveren),
he was, together with Night, Day, and Erebus, begotten by
Chaos and Caligo (Darkness). According to that of Hesiod (Hes.
Th. 124), Aether was the son of Erebus and his sister Night,
and a brother of Day. (Comp. Phornut. De Nat. Deor. 16.) The
children of Aether and Day were Land, Heaven, and Sea, and
from his connexion with the Earth there sprang all the vices
which destroy the human race, and also the Giants and Titans.
(Hygin. Fab. Prof. p. 2, &c.) These accounts shew that, in the
Greek cosmogonies, Aether was considered as one of the
elementary substances out of which the Universe was formed. In
the Orphic hymns (4) Aether appears as the soul of the world,
from which all life emanates, an idea which was also adopted
by some of the early philosophers of Greece. In later times
Aether was regarded as the wide space of Heaven, the residence
of the gods, and Zeus as the Lord of the Aether, or Aether
itself personified. (Pacuv. apud Cic. de Nat. Deor. 2.36, 40;
Lucret. 5.499; Verg. A. 12.140, Georg. 2.325.) - A Dictionary
