Nyx in Greek and Roman Biography and Mythology
（Νύξ), Nox or Night personified. Homer (Hom. Il. 14.259,
&c.) calls her the subduer of gods and men, and relates that
Zeus himself stood in awe of her. In the ancient cosmogonies
Night is one of the very first created beings, for she is
described as the daughter of Chaos, and the sister of
Erebus, by whom she became the mother of Aether and Hemera.
(lies. Theog. 123, &c.) According to the Orphics (Argon. 14)
she was the daughter of Eros. She is further said, without
any husband, to have given birth to Moros, the Keres,
Thanatos, Hypnos, Dreams, Momus, Oizys, the Hesperides,
Moerae, Nemesis, and similar beings. (Hes. Th. 211, &c.;
Cic. de Nat. Deor. 3.17.) In later poets, with whom she is
merely the personification of the darkness of night, she is
sometimes described as a winged goddess (Eur. Orest. 176),
and sometimes as riding in a chariot, covered with a dark
garment and accompanied by the stars in her course. (Eur.
Ion 1150; Theocrit. ii. in fin.; Orph. Hymn. 2. 7; Verg. A.
5.721; Tib. 2.1. 87; V. Fl. 3.211.) Her residence was in the
darkness of Hades. (Hes. Th. 748; Eurip. Orest. 175; Verg.
A. 6.390.) A statue of Night, the work of Rhoecus, existed
at Ephesus (Paus. 10.38.3). On the chest of Cypselus she was
represented carrying in her arms the gods of Sleep and
Death, as two boys (5.18.1). - A Dictionary of Greek and
Roman biography and mythology, William Smith, Ed.
Nyx in Wikipedia
In Greek mythology, Nyx (Νύξ, "night", Nox in Roman
translation) was the primordial goddess of the night. A
shadowy figure, Nyx stood at or near the beginning of
creation, and was the mother of personified gods such as
Hypnos (sleep) and Thßnatos (death). Her appearances in
mythology are sparse, but reveal her as a figure of
exceptional power and beauty...
