New Ceremony in Rite for Installation of a Cardinal

In a revision of the ancient rite, instead of the Holy Father placing the red zucchetto directly on the head of the new cardinal, a small rock is placed inside the zucchetto which is then hurled down onto the candidate's head by the Holy Father from the open window of his apartment. The rite is intended to symbolise (on the one hand) the descent into hell and (on a more practical level) the headaches that the new cardinals can expect to face in their role.
