It has been much restored at various times, but the extreme beauty of the work has in no way been impaired. The white hart, chained and collared, the badge of Richard II., is painted on the pillars. The Chantry of Abbot Parker, or Malverne (1515-1539), has a much mutilated effigy of this, the last Abbot of Gloucester. Vine leaves and grapes adorn the screen, and the base has some heraldic devices and the emblems of the Passion. On the south side is a projecting bracket which Leland tells us marks the grave of Abbot Serlo, the founder of the Norman Church. The bracket is Perpendicular, the effigy Early English, both much mutilated. The figure has a model of a church in his hand, and therefore denotes that the abbot was a founder, but the Early English character of the effigy points to it representing a later abbot than Serlo, and possibly Abbot Foliot (1243). The _North Choir Aisle_, or ambulatory, is original Norman, the windows being filled with Perpendicular tracery. At the north-east corner is Abbot Boteler's Chantry (1433-1450). The old tiles are interesting, amongst which we see some representing the arms of the Boteler or Butler family (three cups). The decoration of the chapel is all Perpendicular work, screens, windows and reredos. This last is very fine, and has some well-carved figures of the Apostles. Here is the effigy of Robert, Duke of Normandy, eldest son of William I., whose wild youth was atoned for by his prowess in the Crusades. He, however, had to endure twenty years' imprisonment, inflicted by his father. The effigy was probably made not long after his death. The chest on which it rests is fifteenth-century work. The effigy was hacked to pieces by Cromwell's soldiers, but the fragments were put together by Sir Humphrey Tracy, and replaced in the Cathedral. [Illustration THE LADY CHAPEL]
