The Northern Lights, the heavenly dancers. I remember my mother waking me up one night to walk under the blue-green lights flickering across the sky. In later years I slept under the Northern Lights on canoe trips. They had to have a place in the book.
There is no reference for them in the English verses by J. Edgar Middleton but there is this in Brebeuf's original verses in Huron:
The okie spirits who live in the sky are coming with a message,
They're coming to say, "Rejoice!
Mary has given birth. Rejoice!
Jesus he is born."
