The =South Porch= is the principal entrance. It is the work of Morwent (1421-1437). Over the doorway stand St. Peter and St. Paul and the four Evangelists, and below them are King Osric and Abbot Serlo, the founders of the Abbey church. In the niches of the buttress stand St. Jerome, St. Ambrose, St. Augustine and St. Gregory. The windows of this porch have been formed by piercing the tracery of the inside. Over the porch is an unfinished parvis. The doors date from the Fifteenth Century. We now enter the =Nave=. “The first impression of the nave changes all earlier thoughts of the age of the building. It is unmistakably Norman, grand beyond expression, but cold, severe and deathly white. The stained glass (mostly modern) of the Norman and Decorated windows fails to supply the evident lack of colour. “There was a time when lines of blue and scarlet and gold relieved the white vaulted roof, when altars agleam with colour and pale flickering lights gave light and brightness to the chill whiteness of this vast and mighty colonnade. On Sunday evenings, when the nave is filled with worshippers and the bright searching daylight is replaced by the yellow gleam of the little tongues of fire above the great and massive arches, the want of colour is little felt, and the noble and severe beauty of the matchless Norman work in the great nave strikes the beholder. The nave of Gloucester, to be loved and admired as it deserves, and as it appeared to men in the days of the Plantagenet Kings, must be seen in one of the many crowded evening services. “Save that the altars with their wealth of colour and light are gone, and the lines of colouring and the glint of gold of the Norman wooden ceiling no longer are visible on the stone-vaulted roof above and the south aisle Norman windows are replaced with exquisite Decorated work of the time of the second Edward, there is no great structural change since the day at the close of the Eleventh Century when Abbot Fulda from Shrewsbury preached his famous sermon to the Gloucester folk, the sermon in which he foretold the death of the imperious and cruel Rufus in words so plain, so unmistakable, that Abbot Serlo of Gloucester, who loved the great wicked King, in spite of his many sins, was alarmed and at once sent to warn his master, but in vain. Rufus disregarded the Gloucester note of alarm, and a few hours later the news of the King of England’s bloody death, in the leafy glades of the New Forest, rang through Normandy and England.
