=The Library= is immediately above the chapter-house, and is of the same octagonal shape. The arrangements also are similar, but the room is less lofty, the carvings less elaborate, and there is no reading. Otherwise, we find the same central pillar, from which similar vaulting ribs spring, with corbels in the walls to receive them. It is not known for what purpose this room was originally intended, but certainly, until recent years, it was not used as a library. The old library, of which there are pictures by Hollar and King, stood to the north of the north transept in the close, or, as it is recorded in the Capitular Acts, vol. 3, "ex parte boreali in cimeterio." Dean Heywood gave £40 to build the library, and though it was not begun in his time, it was completed in the time of his successor, Dean Yotton, who also subscribed to its erection. This was at about the commencement of the sixteenth century, and the building remained until the middle of the eighteenth, when it was demolished. The extent of the library has been increased by opening a doorway into the room above the vestibule. This room, it has recently been decided, was the old chapel of St. Peter. Though an upstairs chapel was not usual, yet it is not by any means unknown, and chapels were even sometimes to be found in the rood lofts of cathedrals. No trace can be found of the fresco, mentioned by Stukeley, of "St. Peter crucified with his head downwards, and two other apostles, etc." He tells us that the chapel was in his time used as a place for storing scaffolding and ladders, and that here was placed the mutilated remains of St. Chad's tomb. The place still shows signs of its ill-usage, little having been done to repair the ravages of the Civil War. The vaulting is much broken, and the walls cracked: these facts strengthen the belief in the tradition that it was on this building, together with the choir, that the great central tower fell during the siege by the soldiers of the Parliament. The library has had many generous donations of books at various times. Under the will of Frances, Duchess of Somerset, the cathedral received the library of her late husband, the Duke, who succeeded his grandfather as Earl of Hertford, and was restored to the family dukedom at the Restoration. The duchess was the daughter of the Earl of Essex who was the favourite of Queen Elizabeth, and whom she afterwards had beheaded. These books numbered about one thousand, and included many rare old Black-Letter chronicles and histories printed in the sixteenth and seventeenth centuries.
