What looks like a survival of the marble chair of the bishop is to be seen in the frithstols of Hexham and Beverley (106). These also are of masonry, and are so similar in design to the ancient marble thrones that one is tempted to speculate that the original usage of sanctuary was for the offender to fly to and occupy the actual throne of the bishop or archbishop. As has been said, in the Early Christian churches both the altar and the seats of the bishop and his clergy were usually at the west end of the church to the west of the High altar, so that the clergy faced towards the east, while the congregation faced towards the west. But early examples occur of churches with the modern orientation. When this was the case, the congregation faced east; and where the ancient position of the throne and benches was retained, the clergy were left in an anomalous position facing west. This led, first to the clergy, then the bishop, migrating elsewhere. The higher clergy took up their position in the return stalls of the choir, facing east; the lower clergy occupied stalls north and south of the choir. As for the bishop, he could not seat himself as before, facing the altar, for his throne would have blocked the entrance into the presbytery. He therefore set up his throne on the south side of the choir, at the eastern end of the southern range of stalls. And this is where we find him in Gothic days. There is one chief exception. In cathedrals served by monks, the bishop was the titular abbot of the house, though the superintendence of the monastery had necessarily to be left mainly in the hands of the prior; and so to this day in some churches the bishop has no throne, but occupies the ancient abbot's stall--at Ely the stall of the Benedictine abbot, at Carlisle the stall of the Augustinian abbot. {107} [Illustration: Durham]
