In mythology, the architect Daedalus builds a labyrinth to enclose, in its center, the Minotaur, a monster with the body of a man and the head of a bull, fruit of the loves of Pasiphae, the wife of Minos, with a white bull sent by Poseidon.
Like the Minotaur in his loneliness and confinement, human beings can build their own labyrinth with their thoughts. These get tangled up and go all over the place, carried away by the charcoal.
