Sometimes the simplest forms are the most difficult to explain. Perhaps the reason for this is that one estimates the problems involved as being too simple, too obvious, and does not seek, therefore, to penetrate to their core. Besides, there is an aura of the primitive and underivative about a literary form we are used to considering as popular; we hardly dare profane it by dry, objective analysis. As the tradition of a community, it shares the anonymity of the latter. Seeking the traces of creative and tradition-conscious personages, we find only an amorphous mass of the unknown. No wonder that the riddle has been relegated back to prehistoric times, permitting us to conceal its problems behind a veil of mystery.
