The discovery of a hitherto overlooked Authurian story, buried in a longer poem, gives the author a precise geographical location for the Grail's original hiding place in Britain - the White Abbey, an Augustan priory in Shropshire. Futher research reveals that the Grail was one of several treasures, also including the Golden Bull of Knossos and the sacred candelabra removed from the temple of Jerusalem, which were taken in 1410 AD from Rome to the safety of Viroconium - modern day Shrewsbury - virtually the last vestige of Roman civilization anywhere in the former Western empire.
