MOZARABIC RITE. Also known as the Rite of Toledo. A ritual used in Spain and the territory now known as Portugal from the sixth through the eleventh centuries. It is almost identical with the Gallican Rite and is still used in the chapel services of the cathedral at Toledo by the chaplains of the college during Mass and Divine Office, and in the marriage ritual in Spanish America. At one time it was called the Gothic or Isidorian Rite because St. Isidore of Seville (560-636) revised it. The Celtic Rite, early used in the British Isles, was related to the Mozarabic.
