ABSTRACT
The remarkable story in which the young Merlin discloses that a pair of fighting dragons-one red and one white-are responsible for the collapse of King Vertigier’s tower is to be found in Geoffrey of Monmouth as well as in Robert de Boron. Psychologically it is Merlin who points out a problem of the opposites, which has become unconscious again, a problem of which the people of the time certainly knew nothing, but by which they none the less felt themselves to be undermined.
