Scotland - Archaeologists are playing down reports that the 25cm diameter artefuct is the legendary 'Cursing Stone of Scone' used by generations of monarchs during the Coronation Oath.
It was found at an old graveyard on the partially inhabited island forming the westernmost of the Inner Hebrides Small Isles which is named after the Bible's Marriage Feast at Canna.
Local lore has it that fossiised remains of the New Testament wedding breakfast were hidden on the island by the Merovingian Line's distaff side [ie bastards] shortly after the fall of Rome.
"It could be one of the leftovers that Mary Magdalene preserved in a slice of wedding cake ritual at her nuptials to John the Baptist," local historian Sir Hamish McSporran said today.
That theory would need to be carbon tested along with ancient dental records that place the hardened morsel at circa AD 30.
Alternative Celtic mythology reckons the lump might have been bitten by a Gallilean polygamist whose bloodline subsequently spawned the Mormons.
Another theory says the 'Cursing Stone' was first passed by a local dinosaur's kidneys during a bout of renal failure during Scotland's darkest cretinaceous period. [WTF that? -'Ed']
The stone has been snapped up by Scotland's Museum of National Cryptozoology which will exhibit the find at its Loch Ness branch.
