The medieval legend of the Grail, a tale about the search for supreme mystical experience, has never ceased to intrigue writers and scholars by its wildly variegated forms: the settings have ranged from Britain to the Punjab to the Temple of Zeus at Dodona; the Grail itself has been described as the chalice used by Christ at the Last Supper, a stone with miraculous youth-preserving virtues, a vessel containing a man's head swimming in blood; the Grail has been kept in a castle by a beautiful damsel, been seen floating through the air in Arthur's palace, and been used as a talisman in the East to distinguish the chaste from the unchaste. In his classic exploration of the obscurities and contradictions in the major versions of this legend, Roger Sherman Loomis shows how the Grail, once a Celtic vessel of plenty, evolved into the Christian Grial with miraculous powers.
