ABSTRACT
Monkwearmouth is not the only church glazing of the late seventh century to be mentioned in contemporary sources. Between 669 and (probably) 678, Wilfrid, Bishop of York, restored York Minster, which had fallen into decay. The windows had previously been unglazed: 'per fenestras introitum avium et imbrium vitro prohibuit, perquod tamen intro lumen radiabat.'3
