The incantation that Hekate is chanting really goes like this:
Go away strix, you night-wandering one;
go away from the people,
you bird whose name is not to be mentioned.
Go away upon swift ships.
It was recorded by the first-century BCE author Verrius Flaccus. I took away the word strix (a female ghost who attacks women and children) since I don’t want to confuse the reader with too many ancient Greek words (though I must admit I love throwing them around).
