Two historians believe that they have really identified the Holy Grail, the goblet Jesus Christ is believed to have sipped from during the Last Supper. Crowds then flocked to the Spanish church that housed the goblet, forcing curators to pull it from display.

León University medieval history lecturer Margarita Torres and art historian José Manuel Ortega del Rio claimed that the goblet at the San Isidro basilica in Leon, Spain is the Holy Grail in their book, Kings of the Grail, reports The AFP. They claim parchment found in Cairo in 2011 lead them on a journey of discovery and that they noticed a piece of the goblet missing, as described in the parchment.

According to The Huffington Post, the Australian explained that the historians believe that the Grail made it from Jerusalem to Cairo. It was given to an emir in Muslim Spain as a gift, then it was given to King Fernando in the 11th Century.

The goblet was known as the Chalice of Doña Urruca, notes The New York Post. The historians say scientific dating showed that the goblet was made between 200 BC and 100 AD, but they admit that they can’t put together the goblet’s first 400 years of existence and can’t prove Christ actually used it.

Still, so many people rushed the church to see the grail that it is no longer on display. But we know what happens if the historians chose poorly.
