“Hidden from the impious, a perfect rose blossoms out of the Grail in the middle of an enclosed garden. [..] The artist of some five centuries ago has conveyed the ideas of wholeness, center, vessel and source. The word ‘grail’ is derived from the French graal and medieval Latin, gradale, ‘in stages’, the name given to a serving dish on which courses were brought in turn throughout the meal.”
