The Pope’s right hand man is the “Camerlengo”, a cardinal.
Chief among the present responsibilities of the Camerlengo is the formal determination of the death of the reigning Pope; the traditional procedure for this was to strike gently the Pope's head three times with a silver hammer and to call his baptismal name (e.g. "Albine, dormisne?", i.e. "Albino, are you sleeping?")
