Note 5 — OF THE ENCLOSURE OF CHOIRS,
Reading edition
The custom of using brass for the material of choir screens is to be traced to a very late period, as at St. Gatier, at Tours; Cathedral, Rouen; and in many of the Flemish cathedrals.
[6] The only instance I have found in England of circular staircases to a rood loft, inside the church, is at Ely, before the old alterations of the choir.
