The story of the Holy Grail is such an intricate tangle of European legends, oriental stories, literary narratives and conjectures, rooted not in the biblical source, as one might suppose, but almost in the pagan folklore motifs of the Celts.
The Holy Grail is most often identified as a serving dish or a chalice that was used by Jesus during the Last Supper.
The Provencal poet troubadour Chrétien de Troyes described the Grail in his novel Perceval or The Story of the Grail (1182). In this novel the Grail is presented in the form of a large dish with precious stones. However, in other works about this artifact – poems and novels – the Grail appears in the form of a bowl, a cup and even a stone. However, none of these works does not enjoy the reputation of an authoritative source of information.
