Question: What burial method requires digging up skeletal remains and was the subject of a 2007 documentary?
Related documents: [0]  [DOC] An ossuary is a chest, box, building, well, or site made to serve as the final resting place of human skeletal remains. They are frequently used where burial space is scarce. A body is first buried in a temporary grave, then after some years the skeletal remains are removed and placed in an ossuary. The greatly reduced space taken up by an ossuary means that it is possible to store the remains of many more people in a single tomb than if the original coffins were left as is. [END] 
[1]  [DOC] The Jesus bloodline is a hypothetical sequence of lineal descendants of the historical Jesus, often by Mary Magdalene, usually portrayed as his wife. Differing and contradictory versions of a Jesus bloodline hypothesis have been proposed in numerous books by authors such as Louis Martin (1886), Donovan Joyce (1973), Andreas Faber-Kaiser (1977), Barbara Thiering (1992), Margaret Starbird (1993), and various websites. Dan Brown's novel "The Da Vinci Code" used the premise for its plot line. The 2007 documentary "The Lost Tomb of Jesus" proposed that evidence existed to show that Jesus was married to Mary Magdalene and that their son was named Judah, based upon inscriptions found on ossuaries discovered in Jerusalem in 1980. Biblical scholar and author James Tabor has recently affirmed his belief in a married Jesus, while Karen King announced the discovery of text in a Coptic papyrus fragment, alleged to be a translation of a lost 2nd century Gospel, in which Jesus is made to refer to "my wife". That fragment is now considered by most experts to be a fake. [END]
