Between the two easternmost piers of the choir is the monument, with effigy, of Bishop MAYEW, (1504-1516; see Pt. II.) The elaborate canopy has been restored, so far as any authority remained for the details. The panels in front of the monument are filled with figures of saints. The effigy, fully vested, and wearing a richly jewelled mitre, should be especially noticed. Under an arch opening to the choir, in the next bay, is a Perpendicular effigy assigned to Bishop DE LOSINGA, (died 1096). Above it is a fragment of good wooden screen-work, of Decorated character. A door in the westernmost bay of this aisle opens to two plain Norman rooms, now used as vestries. In the Perpendicular period an “eastern chamber” of two stories was added to this Norman building, and served as the treasury of the cathedral. XXII. The great _south transept_ retains much of its Norman work, but was much altered during the Perpendicular period. The east wall is entirely Norman, and is covered with five ranges of arcades, all of which are blank except those at the levels of the triforium and clerestory, which open to a wall-passage. The transept is only lighted on this side by two Norman windows in the clerestory. A large Norman arch, including two smaller, all much enriched, occupies the triforium space above the arch opening to the choir-aisle; and perhaps indicates that the Norman triforium [Illustration: BOOKS IN THE LIBRARY. PLATE X. ] has been already mentioned, to the _Archive Room_ and _Chapter Library_, above the great north transept. This room has been thoroughly restored by Mr. G. G. Scott. The Library contains about 2,000 volumes, many of great rarity and interest. Nearly all are chained to the shelves; and the general appearance of the carefully guarded treasures is sufficiently curious. [Plate X.] Among the most remarkable printed books are--A series of Bibles, ranging from 1480 to 1690; Higden’s _Polychronicon_, by Caxton, 1495; Caxton’s _Legenda Aurea_, 1483; and Lyndewode _Super Constitutiones Provinciales_, 1475. Of the MSS., by far the most interesting is an ancient _Antiphonarium_ containing the old “Hereford Use.” This “sets forth not only the services of particular days, the chants to be used and the lectures to be read, but contains a treatise on music and an ample calendar, in which are noted the obits of the benefactors and bishops of the church; and by which, with the aid of the Dominical letter, we are enabled to assign to the volume the date of 1265[37]”. It was purchased at a book-stall in Drury-lane about the year 1820; and redeemed by the Dean and Chapter, who restored it to its original and legitimate resting-place. Here also is preserved, carefully protected by plate glass, the remarkable _Map of the World_, [Plate XI.,] which is one of the most valuable relics of mediæval geography. It was the work of a certain Richard of Haldingham and of Lafford, (Holdingham and Sleaford in Lincolnshire,) who has commemorated himself
