In the category, 'questions I got ages ago and am only now getting to', I want to talk about the Goddess Nyx today. I have received the following reader question:

"Do you know anything about worshiping Nyx in the modern world?"

Nyx (Νυξ) is the deep Night, born from Khaos (Χαος) and the sister-wife of Aither (Αιθηρ, 'Light'). In Hellenic mythology, Nyx draws a veil of darkness between the shining atmosphere of the aither and the lower air of earth (aer) at set times in the day, bringing night to man. In the morning, Her daughter Hêmera (Ἡμερα, 'Day') removes this veil, and exposes the Earth once more to Light. As Hesiod writes in the Theogony:

"[At the ends of the earth, where lie the roots of earth, sea, Tartaros :] There stands the awful home of murky Nyx wrapped in dark clouds. In front of it [Atlas] the son of Iapetos stands immovably upholding the wide heaven upon his head and unwearying hands, where Nyx and Hemera draw near and greet one another as they pass the great threshold of bronze: and while the one is about to go down into the house, the other comes out at the door. And the house never holds them both within; but always one is without the house passing over the earth, while the other stays at home and waits until the time for her journeying come; and the one holds all-seeing light (phaos) for them on earth." [744]
Nyx and Hêmera continually work to both create and dissolve darkness on Earth; Selene (the Goddess of the Moon) moves with Nyx, and Helios (God of the Sun) with Hêmera, as heralded by Eos. In this recap, it is quite obvious we are yet missing a speciffic time of the day: dusk, or the evening. This was in the domain of the Nymphs, in this case the Hesperides (Ἑσπεριδες), who--depending of source--are either the daughters of Nyx or Atlas. Diodorus Siculus, in the 1st Century BC., wrote in his 'Library of History': 

"Now Hesperos (Evening) begat a daughter named Hesperis (Evening), who he gave in marriage to his brother [Atlas] and after whom the land was given the name Hesperitis; and Atlas begat by her seven daughters, who were named after their father Atlantides, and after their mother Hesperides." [4. 26. 2]
Yet, older sources agree that the Hesperides (amongst others like Hypnos and Tartaros) were born from Nyx; Hesiod, for example:
"And Nyx (Night) bare hateful Moros (Doom) and black Ker (Violent Death) and Thanatos (Death), and she bare Hypnos (Sleep) and the tribe of Oneiroi (Dreams). And again the goddess murky Nyx, though she lay with none, bare Momos (Blame) and painful Oizys (Misery), and the Hesperides who guard the rich, golden apples and the trees bearing fruit beyond glorious Okeanos."
In ancient Hellas, Nyx was only rarely the focus of cult worship. Pausanias mentions She had an oracle on the acropolis at Megara, but that is about it. More often, Nyx was worshipped in other major cults, alongside the main deity: there was a statue called 'Nyx' in the Temple of Artemis at Ephesus, the Spartans had a cult of Sleep and Death, conceived of as twins, with Nyx being worshipped as Their mother, etc.
As for modern worship; I have talked before of how I feel all worship is pretty much the same in Hellenismos. The major difference between reconstructive religions and modern ones--especially Pagan ones--is the way worship is conducted. Individual worship of Gods as well as patronage is perfectly acceptable in modern religions, but in Recon religions and the ancient Traditions they were based upon, worship tends to be of the pantheon, not so much the one God or Goddess. What goes for one Olympic God, tends to go for the others as well.
There are five steps to proper, Hellenistic, ritual: procession, purification, prayers and hymns, sacrifice/offerings, prayers of supplication and thanks, usually followed by a feast and/or theatre and sporting events. We can apply this to modern worship quite easily: procession (no matter how short), purification with lustral water (named khernips), a hymn, song or modern poem which praises and draws the Theos in question, a sacrifice of some kind--be it incenses, (mixed) wine, meat or anything else--along with barley seeds tossed on the altar or into the altar fire, prayers or words of thanks, and--in communal rituals--plays, games, or (sports)-competitions. Within communal celebrations, the sacrifice can be some of the (raw) ingredients used to prepare the communal meal that will follow.
Hellenismos is not glamorous; in general, you do the same thing over and over again with minor variations. That is what I love about it. It's simple, clear, and repetitive. As for Nyx, in the Orphic Hymn to Her, torches are prescribed as an offering, and Gods of the night tended to be worshipped at that time as well. Not always, naturally, but the dark night is Her domain. Bring her sacrifices of wine and try to include Her children and husband in your worship as well. Good luck!
