Two Spanish historians claim to have found the Holy Grail

Spanish historians claim that they have discovered the Holy Grail in a church in Leon in northern Spain.

The Spaniards, Margarita Torres and Jose Ortega del Rio, spent three years studying the history of the chalice and last week published a book, 'The Kings of the Grail,' making their case.

The onyx chalice, they explained, was concealed within another antique vessel known as the Chalice of Dona Urruca, which is located in Leon's basilica of Saint Isidore, the New York Post reported.

The historians said it has been there since the 11th century.

The historians' research has been backed up by scientific dating, which estimates that the cup in question was made between 200BC and 100AD.

The scientists admit the first 400 years of the cup's history remain a mystery and they can't prove the chalice ever actually touched Christ's lips.
