Traditional legends are an inexhaustible source of knowledge about the customs, mentality and the character of each nation. Each nation’s singularity shows itself in the specific traits that it develops but also in the way it adopts the elements of other cultures. The purpose of this article is to characterize the traditional culture of Galicia (Spain) according to this principle. The stories based on historical events and Old French and British epics, which preach Christian morality and keep alive ancient superstitions, are an attempt of the traditional society of Galicia to explain the human nature and the world around it.
