The great vaulted hall, now open from end to end, was then divided into five rooms by screens and partitions. The first room included the first two bays of the north end. Instead of pillars, it had in the midst two piers of masonry supporting a staircase, which ascended out of the church into the room above. These piers made this a double room, whereof the western half served as a vestibule to the church, while the eastern half, once opening from the cloister, may sometime have been the treasury, as at Durham. The second room began at the southern pier and extended to the fourth pillar, thus including four bays. This was probably the storehouse for the domestic supplies of food and drink. A door in the west wall opened conveniently upon the outer court. The third room was between the fourth pillar and the sixth. It had a door in its south wall, and appears to have been the buttery. The wall which crossed at the sixth pillar ran between two doors, an outer door into the court and an inner door into the cloister. Thus this fourth room served as an entrance way. Its southern wall had the eighth pillar in the middle of it, and this bay beside the entrance may have been the outer parlour, the _auditorium juxta coquinam_, or room beside the kitchen, which was provided for in the Cistercian arrangements. Here in a niche of the east wall, now blocked, the porter sat beside the cloister door. In this room the brethren of the Abbey met their friends who lived in the world; here merchants came to show their wares. All the rest of the hall, from the eighth pillar to the end over the river, was open then as it is now, and served as the refectory of the lay brothers. They came [Illustration: _The Cloisters._ _Photo. Frith._ _Art Repro. Co.] in by the door in the west wall between the eighth and ninth pillars; their tables were set along the side walls under the windows; their cups and plates may have been kept in cupboards against the blank wall of the last two bays in the south-west corner; their food came in from the abbey kitchen by a hatch which opened opposite the outer door. An outside stairway--the day stairs--rose beside the cellarer’s office at this door, and led to the dormitory of the lay brothers. At the north end of the dormitory another stairway--the night stairs--went down into the church. At the south, a room at right-angles, over the river, where they made their toilet, gave access to the infirmary where they went when they were sick, and in which they lived in peace and Christian comfort when they were old.
