Over the past decades there has been an upsurge of interest in "the Camino, " the pilgrim's route to Santiago de Compostela in northern Spain. Focusing on the spiritual history of humankind, the authors study the cosmic origin of the Grail Mysteries, the School of Athens, early Christian art and its Gnostic impulses, the Grail Initiation in northern Spain, and the role of the Cathars and Troubadours in the Manichaean stream showing how they all come together in the Camino to Santiago de Compostela. They explore the esoteric aspect of music for the pilgrims, the Music of the Spheres and the Elders of the Apocalypse, the Templars as emissaries of the Holy Grail, the initiations of Christian Rosenkreutz and his relation to anthroposophical art, the early Rosicrucian impulses in America and Europe, and much more.
