“In Christian Europe, already in the twelfth century, beliefs no longer universally held were universally enforced. The result was a dissociation of professed from actual existence and consequent spiritual disaster which, in the imagery of the Grail legend, is symbolized in the Waste Land theme: a landscape of spiritual death, a world waiting, waiting – ‘Waiting for Godot! – for the Desired Knight, who would restore its integrity to life and let stream again from infinite depths the lost, forgotten, living waters of the inexhaustible source”.

Joseph Campbell, The Masks of God: Creative Mythology
