In the west end of the Seabroke Chapel, against the first pier of the nave, is a mural monument, rather florid in style, to Francis Baber, 1669.

Close to the Seabroke Chapel, on one of the piers supporting the tower, is a bracket with traces of very beautiful blue colour. The canopy above—much mutilated—shows traces of red, blue, and gold.

Almost opposite to this, but nearer to the iron gate, is a recessed tomb to a knight in mixed armour of mail and plate, and by his side his lady, with kirtle, mantle, and flowing hair. Both wear SS collars, and this helps to give the age of the monument, by narrowing the date down to a year not earlier than 1399. The SS collars also tend to disprove that the monument is to Humphrey de Bohun, Earl of Hereford, and his countess, seeing that he died in 1361. On the knight's belt is a badge, very much worn down, which has been attributed to the Brydges family. Mr Lysons thought it to be the tomb of Sir John Brydges who fought at Agincourt, and died in 1437, but the mail tippet is not found later than 1418. The tomb may commemorate Sir Thomas Brydges, who died in 1407, and this would agree better with the date given above.

The transepts and ambulatory of the choir are entered, as a rule, by the iron gateway in the south aisle of the nave.

South Transept.—This transept, like that on the north, underwent a complete transformation in the fourteenth century, under Abbot Wygmore (1329-1337). In spite of the transformation, the Norman design can easily be traced both in the inside and the outside of the transept. The walls have been ornamented with open panelled work, consisting of mullions and transoms, with very rich tracery and foiled headings. The method of the casing is best seen from the triforium, where the original Norman masonry can be closely inspected. The panel work, in spite of its date, has the appearance of being considerably later, and some have thought the work to have been executed after Wygmore's time.

Professor Willis thinks that the Perpendicular style, which elsewhere—e.g. in the north transept and the choir—is completely developed, may have had its origin in this south transept. In any case, the work is of the greatest architectural interest, and deserves careful study. "Looking at the very early character of the clustered shafts and the mouldings of this transept in conjunction with the vertical lines with which they are associated, one might think (excepting Thokey's south aisle, the Edward II. monument, and some few examples in the triforium of the choir) that Decorated work had never fairly taken root in Gloucester." (F. S. W.)

The south transept, which was also called St. Andrew's Aisle, is 47 feet long, 35 feet broad, and 86 feet in height. The vaulting is lierne vaulting, with short ribs, which connect the main ribs together. There are no bosses in the roof. With an opera-glass it is possible to note the clever joining of the masonry.

On the north side of the south transept, between the tower piers, is an interesting chapel, with a wooden screen—date about 1510. The panelling inside, as also that on the back of the choir-stalls here exposed to view, is covered with monograms of S and B alternately, all surmounted with crowns.

The chapel is said to have been dedicated by John Browne (or Newton), who was Abbot from 1510-1514, to his patron saint, St. John the Baptist, the initials being the same.

On the step in this chapel is a slab with a mutilated cross incised in it and remains of an inscription upon a scroll. It is now almost illegible and crumbling fast away, but it was
