medieval stone coffin

de bene esse: literally, of well-being, morally acceptable but subject to future validation or exception

Excavators finally lifted the heavy lid of a medieval stone coffin found at King Richard III's rediscovered resting place in Leicester, England, only to reveal another lead coffin inside. http://oak.ctx.ly/r/8mcu

The "coffin-within-a-coffin" is thought to have been sealed in the 13th or 14th century — more than 100 years before Richard, an infamous English king slain in battle, received his hasty burial in 1485.
