What is a sacophagus?

A sarcophagus is a funeral receptacle for a corpse, most commonly carved or cut from stone. The Word "sarcophagus" comes from the Greek σαρξ sarx meaning "flesh", and φαγειν phagein meaning "to eat", hence sarkophagus means "flesh-eating"; from the phrase lithos sarkophagos (λιθος σαρκοφάγος) the Word came to refer to the limestone that was thought to decompose the flesh of corpses interred within it.
