    • n grail In medieval legend, a cup or chalice, called more particularly the holy grail or sangreal, supposed to have been of emerald, used by Christ at the last supper, and in which Joseph of Arimathea caught the last drops of Christ's blood as he was taken from the cross. By Joseph, according to one account, it was carried to Britain. Other accounts affirm that it was brought by angels from heaven and intrusted to a body of knights, who guarded it on the top of a mountain; when approached by any one not perfectly pure it vanished from sight. The grail having been lost, it became the great object of search or quest to knights errant of all nations, none being qualified to discover it but a knight perfectly chaste in thought and act. The stories and poems concerning Arthur and the Knights of the Round Table are founded on this legend, and it has been still further developed in modern times. See sangreal.
