Miriam (Mary) is a very common name. Even within the Gospels there were many Marys (Mary the mother of Jesus, Mary Magdalene, Mary the wife of Celophas, etc)... The sensationalism of the title notwithstanding, the article is a big nothing. Besides the reference to Miriam, it tries to also imply that the graves contain the bones of "Yehoshua bar Yoseph” (I presume this is supposed to be Jesus - son of Joseph)... and “Yehuda bar Yeshua (Jesus)". As stated by many others - if the grave of Jesus, or his bones, were available, they would have been placarded to put down this 'outrageous' claim that Jesus is the Christ who died (according to Scriptures), and was buried, and rose again (according to Scriptures). When Peter boldly proclaimed the Risen Saviour on that Pentecost day in Jerusalem (Acts 2), there was no response from the authorities. No grave, no bones to show...
So someone found some graves making references to some very common names at that time - OK. Extrapolating further is a waste of time and energy.
Hmmm I certainly know nothing about translating ancient hebrew inscriptions on ossuaries but Dan Brown and James Cameron teaming up together in support of this “find” certainly does make me skeptical....
