Altar bell

In the Roman Rite of the Catholic Church, Lutheranism, and Anglicanism, an altar bell (also Mass bell, sacring bell, Sacryn bell, saints' bell, sance-bell, or sanctus bell) is typically a small hand-held bell or set of bells. The primary reason for the use of such bells is to create a "joyful noise to the Lord" as a way to give thanks for the miracle taking place atop the altar.

An ancillary function of the bells is to focus the attention of those attending Mass that a supernatural event is taking place on the altar. These are kept on the credence table or some other convenient location within the chancel.
