“ When the pope celebrates Mass a special credence table on the Gospel side of the altar is used, and the ceremony of tasting for poison in the unconsecrated elements is still observed. In some churches in England the old credence tables still exist, as at the church of St Cross near Winchester, where there is a fine stone 15th-century example; more frequent are examples of the stone shelf near the piscina. There are some carved wooden ones surviving, one type being with a semicircular top and three legs placed in a triangle with a lower shelf. ”
