Jack's tale is rich in symbols related to the communication between the earthly world and the celestial world. The common edible bean, a banal edible plant, grows as long as it comes to touch the sky, becoming a kind of World Tree, the cosmic tree. Tales often talk about animals that produce gold. But the importance of the golden egg chicken is rather in the fact that it is a chicken, which, like the swan and goose, is a messenger of the Other World. As for the golden harp, it usually connects the earth and the sky: from a material frame of wood and strings are drawn vibrations whose harmony gives the music.
