Question: What burial method requires digging up skeletal remains and was the subject of a 2007 documentary?

A charnel house is a vault or building where human skeletal remains are stored.  They are often built near churches for depositing bones that are unearthed while digging graves.  The term can also be used more generally as a description of a place filled with death and destruction. <SEP>  They are frequently used where burial space is scarce. An ossuary is a chest, box, building, well, or site made to serve as the final resting place of human skeletal remains.  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. <SEP> Ewald summation, named after Paul Peter Ewald, is a method for computing long-range interactions (e.g., electrostatic interactions) in periodic systems.  It was first developed as the method for calculating electrostatic energies of ionic crystals, and is now commonly used for calculating long-range interactions in computational chemistry.  Ewald summation is a special case of the Poisson summation formula, replacing the summation of interaction energies in real space with an equivalent summation in Fourier space.  In this method, the long-range interaction is divided into two parts: a short-range contribution, and a long-range contribution which does not have a singularity.  The short-range contribution is calculated in real space, whereas the long-range contribution is calculated using a Fourier transform.  The advantage of this method is the rapid convergence of the energy compared with that of a direct summation.  This means that the method has high accuracy and reasonable speed when computing long-range interactions, and it is thus the de facto standard method for calculating long-range interactions in periodic systems.  The method requires charge neutrality of the molecular system in order to calculate accurately the total Coulombic interaction.  A study of the truncation errors introduced in the energy and force calculations of disordered point-charge systems is provided by Kolafa and Perram. <SEP>  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. 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.  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.
