Orphic literature in the context of "Nyx (mythology)"

The Erinyes (/ɪˈrɪni.iːz/ ih-RI-nee-eez; Ancient Greek: Ἐρινύες, sg. Ἐρινύς Erinys), also known as the Eumenides (Εὐμενίδες, the "Gracious ones"), are chthonic goddesses of vengeance in ancient Greek religion and mythology. A formulaic oath in the Iliad invokes them as "the Erinyes, that under earth take vengeance on men, whosoever hath sworn a false oath". Walter Burkert suggests that they are "an embodiment of the act of self-cursing contained in the oath". Their Roman counterparts are the Furies, also known as the Dirae. The Roman writer Maurus Servius Honoratus (c. 400 AD) wrote that they are called "Eumenides" in hell, "Furiae" on Earth, and "Dirae" in heaven. Erinyes are akin to some other Greek deities, called Poenai.

According to Hesiod's Theogony, when the Titan Cronus castrated his father, Uranus, and threw his genitalia into the sea, the Erinyes (along with the Giants and the Meliae) emerged from the drops of blood which fell on the Earth (Gaia), while Aphrodite was born from the crests of sea foam. Apollodorus also reports this lineage. According to variant accounts, they are the daughters of Nyx ('Night'), while in Virgil's Aeneid, they are daughters of Pluto and Nox (the Roman name for Nyx). In some accounts, they were the daughters of Eurynome (a name for Earth) and Cronus, or of Earth and Phorcys (i.e., the sea). In Orphic literature, they are the daughters of Hades and Persephone.

In Greek mythology, Erebus (/ˈɛrəbəs/; Ancient Greek: Ἔρεβος, romanized: Érebos, lit. 'darkness, gloom'), or Erebos, is the personification of darkness. In Hesiod's Theogony, he is the offspring of Chaos, and the father of Aether and Hemera (Day) by Nyx (Night); in other Greek cosmogonies, he is the father of Aether, Eros, and Metis, or the first ruler of the gods. In genealogies given by Roman authors, he begets a large progeny of personifications upon Nox (the Roman equivalent of Nyx), while in an Orphic theogony, he is the offspring of Chronos (Time).

The name "Erebus" is also used to refer either to the darkness of the Underworld, the Underworld itself, or the region through which souls pass to reach Hades, and can sometimes be used as a synonym for Tartarus or Hades.

In Greek mythology, Nyx (/nɪks/ ; Ancient Greek: Νύξ, lit. 'Night') is the goddess and personification of the night. In Hesiod's Theogony, she is the offspring of Chaos, and the mother of Aether and Hemera (Day) by Erebus (Darkness). By herself, she produces a brood of children which are mainly personifications of primarily negative forces. She features in a number of early cosmogonies, which place her as one of the first deities to exist. In the works of poets and playwrights, she lives at the ends of the Earth, and is often described as a black-robed goddess who drives through the sky in a chariot pulled by horses. In the Iliad, Homer relates that even Zeus fears to displease her.

Night is a prominent figure in several theogonies of Orphic literature, in which she is often described as the mother of Uranus and Gaia. In the earliest Orphic cosmogonies, she is the first deity to exist, while in the later Orphic Rhapsodies, she is the daughter and consort of Phanes, and the second ruler of the gods. She delivers prophecies to Zeus from an adyton, and is described as the nurse of the gods. In the Rhapsodies, there may have been three separate figures named Night.

The Orphic Hymns are a collection of eighty-seven ancient Greek hymns addressed to various deities, which were attributed in antiquity to the mythical poet Orpheus. They were composed in Asia Minor (located in modern-day Turkey), most likely around the 2nd or 3rd centuries AD, and were used in the rites of a religious community which existed in the region. The Hymns are among the few extant works of Orphic literature (the tradition of texts attributed to Orpheus in antiquity), and recent scholars have observed parallels between the collection and other Orphic works.

The collection is preceded by a proem (or prologue), in which Orpheus addresses the legendary poet Musaeus, and calls upon around seventy deities to be present. The individual hymns in the collection, all of which are brief, typically call for the attention of the deity they address, before describing them and highlighting aspects of their divinity, and then appealing to them with a request. The descriptions of deities consist primarily of strings of epithets (titles or adjectives applied to gods), which make up a substantial portion of the hymns' content, and are designed to summon the powers of the god. The deity featured most prominently in the collection is Dionysus, who is the recipient of eight hymns, and is mentioned throughout the collection under various names. Most of the deities featured in the Hymns are derived from mainstream Greek mythology, and a number are assimilated with one another.
