Catholic Dictionary




A movable altar consisting of a solid piece of natural stone, generally of a size large enough to hold the Sacred Host and the greater part of the base of a chalice. It bears on its upper surface five crosses cut into the stone, where the anointings are made when it is liturgically consecrated. Near the edge is a sepulcher or cavity that contains the relics of two martyr-saints, and sealed with a cemented stone lid. Also called an altar stone.
