Earth Laid upon a Corpse
Old Scottish superstition described by eighteenth-century writer Thomas Pennant. It was the custom in the Highlands to lay on the breast of the deceased a wooden platter containing a little earth and a little salt—the former to symbolize the corruptibility of the body, the latter the incorruptibility of the soul.
