We now enter the church at the west end, and are struck by the noble character of this magnificent Norman work. It consists of twelve bays (there were thirteen before the central tower fell). The two eastern bays were finished by Abbot Richard (1100-1107), and the rest completed by Bishop Riddell (1147-1189). The earlier character of the five bays nearer the central tower is discoverable. The ceiling was painted forty years ago by Mr. le Strange and Mr. Gambier Parry, whose artistic work can also be seen at Gloucester. The subjects are the Creation, the Fall, Noah Sacrificing, the Sacrifice of Isaac, Jacob's Dream, Marriage of Ruth, Jesse, David, Annunciation, Nativity, Adoration of the Shepherds and Magi, the Lord in Glory. We see also representations of the patriarchs and prophets, and in the medallions at the sides the heads of the human ancestors of our Lord. The west window was inserted at the close of the eighteenth century and filled with modern glass (when the roof of the upper hall of the porch was removed), thus effectively blocking the view of the three great lancets, 40 feet further west, through which, up to that time, the setting sun must day by day, through so many centuries, have flooded the nave with its evening light. [Illustration ST. CATHERINE'S CHAPEL] At the west end, under the tower, we notice the strengthening of the original pillars with additional Perpendicular work. The arches of the tower, though Norman, are pointed, showing that they were erected at the end of that period, and the richness of ornament and detail of the southern portion of the west transept bears out the same conclusion. _St. Catherine's Chapel_ is in the south corner, rebuilt in the old style, and the font is modern. The _Nave Aisles_ have arcades of Norman arches, and the chevron moulding appears about them in several parts where it has not been cut away. In the south aisle is an interesting memorial of Ovin, the steward of St. Etheldreda, which has been recovered from a neighbouring village. It is part of a cross, with the inscription on the base--"_Lucem tuam Ovino da Deus et requiem. Amen._" (O God, give light and rest to Ovin. Amen). The _Octagon_ would require a volume adequately to record its many beauties and perfections. We have already described its construction. It is pronounced by all architects as the gem of the Cathedral, and one of the most beautiful buildings in the world. The vault is of wood, and a remarkable series of paintings appears on the boarding. The Crucifixion and the Apostles are here represented. Large corbels have sculptured scenes of the life of St. Etheldreda. The vault has been painted by Mr. Gambier Parry. [Illustration IN SOUTH AISLE OF NAVE LOOKING TO NORTH TRANSEPT]
