Here a Grail, There a Grail: Grail Cups Part 2

"The Chalice bears the name for the Benedictine leader of Saint Denis; Abbot Suger (1122 -1151)... The Chalice in the above link is actually one of four Chalices that have survived to present day that Abbot Suger brought to Saint Denis. The other three are now in the Lourve. While Abbot Suger’s Chalice follows the same pattern of an ancient agate bowl in a medieval setting, it is doubtful it is the Grail. There really is no historical pedigree to back up any claims to the contrary. This Chalice’s home is the National Gallery of Art in Washington DC."
