In “High John De Conquer”, Zora Neale Hurston reports that:
like King Arthur of England, he has served his people. And, like King Arthur, he is not dead. He waits to return when his people shall call him again … High John de Conquer went back to Africa, but he left his power here, and placed his American dwelling in the root of a certain plant. Only possess that root, and he can be summoned at any time.
