Will-o'-the-Wisp
He wasn’t let into heaven and he wasn’t let into hell, so he is now travelling around the world with his wisp of straw, and that is the person we call ‘Will-o-the-Wisp’.
The Great Blasket by W.B. Yeats
A few more years and a tradition where Seventeenth Century poets, Mediaeval storytellers, Fathers of the Church, even Neoplatonic philosophers have left their traces in the whole poems of fragmentary thoughts and isolated images will have vanished.
