Two major spiritual currents run through the narrative world of the people of the early Middle Ages. On one side, there is the world of King Arthur's Round Table and his knights: a spiritual center that draws its strength from the well of ancient druidism, yet at a crucial point merges into Christianity. Merlin the Seer plays an important role here with his counsel and guidance.

On the other side, we experience the mysterious esoteric current of the Grail narrative, which is deeply rooted in Christianity. Through the deeds of the knights of the Round Table, particularly Perceval, both paths ultimately converge into a powerful spiritual current that stretches through the centuries, reaching into our time.

How can the enduring and widespread interest in these tales of King Arthur and the Grail be explained? Is it the courtly world of knights that the storytellers of the twelfth and thirteenth centuries used as a framework, with all its adventures and entanglements? The answer likely lies on a level that transcends the real world, where the great imaginative images and spiritual truths reside, speaking directly to the hidden depths of the human heart.

In the twelve studies of this book, the author attempts to illuminate these spiritual realities behind the Arthurian and Grail stories with the help of Rudolf Steiner's anthroposophy.
