If you don't know Dorothy Edwards' 1981 The Witches and the Grinnygog, you're in for a treat. (For those of you who didn't grow up speaking Witch, a Grinnygog is a “Himmage” of the Horned God.) Even the 1983 BBC children's miniseries version has its moments.
One of the best is this old Witch song, half-remembered by their contemporary descendants among families of the Old Blood.
Both the book and TV versions are incomplete, so I put the pieces together along with some of my own. Just add round dance and voilà: a sweet little power-raising chant for your next coven meeting, singable to the tune of the show's title song.
Don't quite understand it all? That's by design. (Hint: "horn" here is a verb.)
That's witching for you: always leave room for mystery.
