There is no great quantity of painted glass in the church, but much of it is of good quality. The windows of the choir, on either side of the Lady-Chapel, are as rich as a profusion of brilliant colors can make them; but the figures are so small, and so crowded, that the subjects cannot be traced. They are said to be the work of the thirteenth century. The painted windows in St. Stephen's chapel, of the sixteenth century, are generally considered the best in the cathedral. I own, however, that I should give the preference to those in the chapel of St. Romain, in the south transept. One of them is filled with allegorical representations of the virtues of the archbishop; another with his miracles: every part is distinct and clear, and executed with great force and great minuteness. The vestments of the saint have all the delicacy of miniature-painting. The library of the cathedral, formerly one of the richest in France, disappeared during the revolution; but the noble room which contained it, one hundred feet long, by twenty-five feet wide, still remains uninjured; as does the door which led into it from the northern transept, and which continues to this day to bear the inscription, _Bibliotheca_. The staircase, communicating with this door, is delicate and beautiful. The balustrades are of the most elegant filagree; and it has all the boldness and lightness which peculiarly characterise the French Gothic. Its date being well ascertained, we may note it as an architectural standard. It was erected by the archbishop, Cardinal d'Etouteville, about the year 1460, thirty or forty years subsequently to the building of the room.
