A sarcophagus is a stone container for a coffin or body. The word comes from Greek "sarx" meaning "flesh", and "phagein" meaning "to eat", so sarcophagus means "eater of flesh"....
Sarcophagi were usually made by being carved, decorated or built ornately. Some were built to be freestanding above ground, as a part of an elaborate tomb or tombs. Others were made for burial, or were placed in crypts. In ancient Egypt, a sarcophagus was usually the external layer of protection for a royal mummy, with several layers of coffins nested within.
