It is customary to credit the Reformation or the Civil War with most church desecration and destruction, but this window was ruthlessly destroyed by an order of the Chapter in 1679, nearly thirty years after the Civil War was ended, and nearly 140 years after the dissolution of the monastery. The order ran as follows: "That a certain scandalous picture of y'e Holy Trinity being in y'e west window of y'e Quire of y'e said church, should be removed, and other glass put into y'e place." The glass of the window was actually broken up by one of the prebendaries (Fowler by name) with his own hands and feet. His action, considering his views, was incomprehensible; but he was made Bishop of the diocese, after Bishop Frampton was deprived of his see. Beneath the west window is an inscription (restored) in the panelling of the stone work: Hoc quod | digestum | specularis | opusque | politum | Tullii haec Ex onere | Seabroke | abbate | jubente. These two Latin verses record that "this work (viz. the tower) which you see built and adorned, was done by the labour of Tully, at the command of Abbot Seabroke." Robert Tully was a monk of Gloucester, and was Bishop of St. David's, where he died in 1482. There is a brassless slab to his memory there, but the best monument is the tower that was built by him here in Gloucester. After passing through the iron gate into the last bay of the south aisle, the tomb of Abbot Seabrook or Seabroke will be seen on the left, inside a stone screen, through which formerly was a doorway giving access to the organ loft. The alabaster effigy represents the Abbot in his alb, stole, tunic, dalmatic, chasuble, amice, and mitre, with his pastoral staff on his right side. The chapel has been partially restored. Traces of colour are to be seen in the reredos and the roof over it. Abbot Seabroke's pastoral staff was discovered in 1741 in his coffin while the tomb was being removed. After changing hands many times it was acquired finally by the Antiquarian Society of Newcastle-on-Tyne. 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.
