The South Transept (or St. Andrew's Aisle), as far as the walls are concerned, is thought by some to have been built by Serlo, but there have been so many alterations in the exterior that it is difficult to say anything with certainty. Fosbroke, writing at the end of last century, noted that there was an inscription on the outside wall making mention of one William Pipard, who was sheriff of the county about sixty years after Serlo's time. The windows have been enlarged and much altered, and later tracery has been inserted.
In spite of the many alterations and some restoration, the south front of this transept contains much interesting Norman work, which has been re-used in a very clever way. The square flanking towers, with their later spires, the arcading over the head of the window, and the graceful curve in the battlement are all worthy of attention, and will serve to confuse visitors before they realise that the Norman architecture is concealed under a later casing, and that there is a great deal of old work re-used in the new.
There is a curious buttress, too, which goes across the west window of this transept to strengthen the south-west corner of the great tower. In fact, the south side of the church is the only side that, as builders say, has "settled" at all.
In 1867 a Roman tesselated pavement was discovered near the south front of this transept.
The Tower.—Of all the exterior beauties, the most striking is the beautiful and graceful tower. Placed where it is, almost in the centre of the long line of the nave, continued in the choir and Lady Chapel, at the point where the transept line intersects it, it is the chief feature of the massive pile. All else seems to be grouped with a view to the enhancing of the effect of the central position of the tower. The other members of the building seem merely to be steps, by means of which approach can be made to it. It is the grandest and most impressive feature of the outside. No matter from whence one looks at it, the charm is there. Seen from the gardens in the side streets close by when the pear-trees are in bloom, or in the full blaze of a hot summer day, or again later in the autumn when the leaves are beginning to turn, or, better still, in snow time, it is always full of beauty. On a bright hot day the pinnacles seem so far off in the haze as to suggest a dream of fairyland. On a wet day, after a shower, the tower has the appearance of being so close at hand that it almost seems to speak. Viewed by moonlight, the tower has an unearthly look, which cannot well be described. The tower is 225 feet high to the top of the pinnacles, and the effect of it is extremely fine. From the main cornice upwards, the whole of the stonework is open, and composed of what at a distance appears to be delicate tracery, and mullions, and crocketed pinnacles.
It is, in all probability, the third tower that has been built since Aldred's time. There are piers still remaining of the Norman tower erected by Serlo in the years that elapsed between 1089 and 1100; and, as we are told in the "Saxon Chronicle," that in 1122 a fire which originated in the upper part of the steeple burnt the whole monastery, it must be inferred that the superstructure was of wood. A hundred years later it is known that the great eastern tower was built with the help of Helias of Hereford. This tower was in great part taken down by the monk Tully, and rebuilt in the Perpendicular style in the time of Abbot Seabroke (1450-1457).
The Bells at Gloucester are peculiarly interesting from the fact of their age, and from the fact that they escaped the clutches of the despoilers at the time of the Dissolution. The truth of the matter seems to be that all the "Churche goods, money, juells, plate, vestments, ornaments, and bells" had been inventoried and handed over to the king's commissioners in Bishop Hooper's time. The commissioners returned to the Dean and Chapter "to and for the use and behouf of the seid Churche, one chalys being silver and whole gilte without a paten waying xi oz. and also one grete bell whereuppon the cloke strykithe, and eight other grete bells whereupon the chyme goethe hangynge in the towre there within the seid church save and surely to be kept untill the King's Majesty's pleasure shall be therein further knowen." This was dated May 27th, 1553, and as the king died within three months his pleasure in the matter was never "further knowen," and Gloucester rejoices still in its bells.
The chimes[2] play four tunes, which are changed every other day. The first tune was composed by Dr Jefferies in 1791; the second by Dr Hayes, who died 1777; the third by Dr Malchair, 1760-1770; and the fourth by Dr Stevens. The composers of the second and fourth tunes were both natives of Gloucester, and at one time choristers in the cathedral.
