Watcher of the night
May your gentle cool light
Guide us through the darkness
Ever mindful of the wolf at our heels.
Don't forget to step outside tonight and marvel at our beautiful Blue Moon. :)
Mani is unusual because lunar deities tend to be female, nearly universally, probably because of the connection between Menstruation and the phases of the moon. See also Vidfinn for a hypothesis about the source of the nursery rhyme called Jack and Jill.
The Moon is always masculine in Germanic language and culture, just as the Sun is always feminine. Traces of this concept survive even today in the English "the Man in the Moon". The Moon is the brother of the Sun: and like her he is seen as driving a wagon drawn by a horse called Hrimfaxi (Ice-Mane) and chased by a troll in wolf-shape who will devour him at Ragnarok. He drives the wagon which carries the Moon across the sky of Night, and is considered to be the embodiment of its Holy might.
