What is the technical name for the unique Coptic funerary tradition, dating from the 4th century, of burying the dead in a sitting or standing position in monastery cemeteries — a practice abandoned by mainstream Christianity but preserved in isolated desert monasteries?

• A Wall-niche inhumation
• B Mummy-style vertical burial (al-dafn al-waqif) ✓
• C Columbarium interment
• D Crypt benching

The practice of al-dafn al-waqif (standing burial), where monks and saints were interred upright in niches carved into monastery walls — a continuation of pharaonic mummification posture that was retained in Coptic monasticism as a sign of readiness for resurrection — survives only in a handful of remote monasteries in the Eastern Desert.
