As we approach winter, the nights will get longer. Days will become darker. For this time is when the sun is barely visible as it's so low on the horizon. Further north, the sun isn't even visible and the grim season is fast moving, as the starry cloaked goddess of night gallops on her winged black steed.
Her name is Nott. She's a personification of night time. She is a mysterious and ancient goddess in Germanic mythology, whose name "Nott" (or Nat) means "night". This nocturnal goddess has a variety of nick names according to the Poetic Edda. The dwarves call her "the goddess of dreams." Elves call her "the goddess who brings joy in sleep". The giants call her "un-light" and the gods call her "goddess of darkness". She is the absence of light, and makes the stars appear visible to us every night. She is total darkness, night itself, and some describe her as a shadow goddess. She rides upon a black chariot pulled by her winged black horse, Hrimfaxi (meaning the "frost mane"). It's worth mentioning that a similar horse named Shadowfax appears in the Tales of Middle Earth by Tolkien.
Nott is a much earlier goddess. She predates the Viking age and reference to her can be traced as far back as the Iron Age. This type of goddess is from a time when humans were primitive. She's the granddaughter of a giant sky god, Bergelmir, who built Asgard. According to myth, she married three times. She is the mother of Dag (a god of day), Jord (the earth goddess) and Aud and she's the grandmother of Thor. She may have had other children. Nott travels the world to bring night, and her horse scatters dew and frost.
This goddess is a keeper of magic, secrets and wisdom. She can be a goddess of the inner night (subconscious) as well as the external night hours. She is a goddess of darkness and the cosmos. She is also the goddess of the obsidion mirror, the poles, the womb, ghosts, magic, alchemy. She's a goddess of the supernatural, the dead as well as the living, birth and death, and anything else that is without light but contains unseen forms.
Ancient Indo-European tribes branched out after the end of the last Ice Age and these stories of gods came from an earlier source. It's likely that certain gods and goddesses in different myths can have the same origin. In Greek mythology, the goddess of night appears as Nyx, the helper of heroes and demigods, who invokes sleep. Just like Nott, Nyx is the mother of the god of day. She has her own starlit temples.
Nott is a cosmic goddess who rules over shadows, stars the nebula. Dark goddess of all things hidden, like caves, deep sleep, vision quests, dreaming, creativity, inner knowledge, insight, divination, outer space and the unknown. Some people are afraid of the great dark goddesses. Maybe She reveals some truth that is presently invisible and undiscovered.
