A gremiale, sometimes anglicized as gremial, is a square or oblong cloth which a bishop, according to the "Cæremoniale Episcoporum" and "Pontificale", should wear over his lap, when seated on the throne during the singing of the Kyrie, Gloria and Credo by the choir, during the distribution of blessed candles, palms or ashes, during the washing of feet in the Mass of the Lord's Supper, and also during the anointments in connection with Holy orders. The gremiales used at other functions are made of linen, to facilitate their cleansing in case they be soiled.
