For centuries the intricately carved stones of Rosslyn Chapel near Edinburgh have tantalised historians, archaeologists and devoted Christians.
A labyrinth of vaults beneath the 15th-century home of the Knights Templar is reputed to contain dozens of holy relics, including early gospels, the Ark of the Covenant, the fabled Holy Grail – and even the mummified head of Christ.
[But..uh...wouldn't that mean...never mind.]
More than 550 years after the first foundation stones were laid, modern technology is about to put the legend to the test.
A group of Knights Templar, successors to the warrior monks who sought asylum from the Pope by fleeing to Scotland in the early 14th century and fought for Robert the Bruce at Bannockburn, are to make a "non-invasive" survey of the land around the chapel. They will use the latest ultrasound and thermal imaging technology in the hope of finding evidence of the existence of the vaults......
....One theory suggests that one of the ornate columns, known as the Apprentice Pillar, may contain a lead casket in which is hidden the legendary cup used by Christ at the Last Supper and later used to collect his blood, the so-called Holy Grail. "Once we understand the introduction page we will begin to understand what this book in stone means," Mr Ritchie added. "We hope to start as soon as possible and get a load of readings from it. We hope to at least find this burial place and maybe the Holy Grail itself."
