It's the most precious object in Christendom. Charged with divine power. Visible only to the pure of mind and body. Rumored at times to be a platter, a stone or most recently, a chalice, it's said to have held the blood of the dying Christ. And since medieval times, the Holy Grail has held a powerful fascination for those in pursuit of it-from rank charlatans to religious visionaries. Investigate tantalizing evidence of the Grail's survival into modern times, and see how eerily similar Grail stories persisting across cultures continue to inspire the search for the mystic power-source of this most sacred of vessels.
