There are also necromantic processes, comprising the tearing up of earth from graves with the nails, dragging out some of the bones, setting them crosswise on the breast, then assisting at midnight mass on Christmas Eve, and flying out of the church at the moment of consecration, crying: ‘Let the dead rise from their tombs!’—then returning to the graveyard, taking a handful of earth nearest to the coffin, running back to the door of the church, which has been alarmed by the clamour, depositing the two bones crosswise, again shouting: ‘Let the dead rise from their tombs!’—then, if we escape being seized and shut up in a madhouse, retiring at a slow pace, and counting four thousand five hundred steps in a straight line, which means following a broad road or scaling walls; finally, having traversed this space, lying flat upon the earth as if in a coffin, repeating in doleful tones: ‘Let the dead rise from their tombs!’—and calling thrice on the person whose apparition is desired to appear.
