 The habit must have proven quite persistent, for the Third Council of Braga in 675 AD saw the need to order that bishops, when carrying the relics of martyrs in procession, must walk to the church, and not be carried in a chair, or litter, by deacons clothed in white.In the Catholic Church, Popes were carried the same way in Sedia gestatoria, which was replaced later by the Popemobile.A palanquin is a covered litter, usually for one passenger.
