While on holiday in Spain researching a book, American author and writer Janice Bennett, found herself looking at an exhibit in the cathedral in Valencia, which was claimed to be the Holy Grail. Although initially unimpressed she decided to find out more and her subsequent research took her on an exciting voyage of discovery, from first century Jerusalem to 21st century Spain. By tracing the history of this relic and examining all the supporting evidence, she has concluded that it could well be what claims believe it to be. The power and symbolism of the Quest for the Holy Grail has had a huge impact on western culture for centuries, and this programme sets out to understand what within biblical tradition and emerging Christianity was meant by the grail, and how historic events, myth and the Middle Ages turned it into something completely different.
