The cloister at Durham, or at least that part of it which was used as a library, was glazed; but whether with white glass or stained glass we are not informed. So obvious a device for increasing both the comfort and the beauty of a much-frequented part of the monastic buildings was doubtless adopted in many other Houses. At Bury S. Edmunds part at least of the cloister had "painted windows representing the sun, moon and stars and the occupations of the months"; at Christ Church, Canterbury, Prior Sellyng (1472-94) "had the south walk of the cloister glazed for the use of the studious brethren"; at Peterborough the windows of the cloister were all compleat and fair, adorned with glass of excellent painting: In the South Cloyster was the History of the Old Testament: In the East Cloyster of the New: In the North Cloyster the Figures of the successive Kings from King _Peada_: In the West Cloyster was the History from the first foundation of the Monastery of King _Peada_, to the restoring of it by King _Edgar_. Every window had at the bottom the explanation of the History thus in Verse[207]. At Westminster, as recorded above, traces of the insertion of glass have been observed. In later times, when regular libraries had been built for the monasteries, a special series of portraits occasionally appeared in glass, on a system similar to that worked out in other materials in Roman and post-Roman libraries; and sometimes, in other libraries, subjects are to be met with instead of portraits, to indicate the nature of the works standing near them. But I cannot say whether cloister-glass was ever treated in this way. FOOTNOTES: [115] _Epist._ XLIX. Sec. 3. Ad Pammachium.
