in Milan cathedral and St Mark's, Venice, the stalls of the clergy and singers are placed on either side of and at the back of the high altar; the apse, with infinite loss to the dignity of the services, being made to serve both as sanctuary and choir. {17} [Illustration: Lincoln] {18} [Illustration: York Minster] {19} There is, however, an alternative plan, which may have been in use from the first simultaneously with the other. At any rate it can be but little later, for in 386 was begun the important church of St Paul _extra muros_ at Rome, with apse to the east and nave to the west. By this alteration, if no further change had been made, the congregation would face eastward, but the celebrant and the bishop with his presbyters westward. Strangely enough, this curious arrangement was actually adopted at least once in England. In the walling of the semicircle of the cathedral apse at Norwich there still remains the bishop's throne and portions of the seats of his clergy. And since Norwich cathedral is not orientated to the west, but to the east, it follows that the people faced east and the bishop and clergy west; it is hardly conceivable, however, that the celebrant can have faced west. Such a disposition can never have been but rare. A new arrangement was made; in the first place the celebrant was made to face eastward, with his back to the congregation, thus permanently obscuring their view of the altar and of many portions of the office; in spite of its obvious and great disadvantages this position has been retained in the vast majority of Western churches ever since. There remained the question of the seating of the bishop and presbyters. The remedy adopted was to transfer them from the apse to the nave; the result being that they sat to the west instead of to the east of the altar. In this second position for some considerable time the seats of the clergy remained. At S. Clemente, S. Maria in Cosmedin,[6] and other basilican churches in Rome, the seats of the clergy still remain in the eastern bays of the nave, separated off, however, all round by low marble screens, which, at S. Clemente, are mainly those of the sixth century church. Great was the revolution wrought in church planning by the determination that the laity, clergy, and celebrant should all alike face East. To the Catholic believer nothing was of more mystic import than the orientation of the church. He prayed toward the East, toward the Holy Land where his Lord lived and died and was buried; he looked forward to the dawn of that day when He should come from the East to judge the quick and dead.
