( .... with apologies to Geoff and Vicki at All the Stations).
For some time now, Zero and I have been making use of a Two Together railcard to visit towns with cathedrals. Our visit to Oxford ignored Christ Church cathedral and instead took in Keble College, and the chapel there. One realises in later life just how much one should have appreciated something when living next door to it in one's younger days.
An account of the architecture of the chapel at Keble can be found here; and images of the mosaics that decorate the walls of the chapel can be found by following the links from this page.
Together the windows and mosaics are intended to show God's dealings with his people through history. They therefore include Old Testament figures such as Abraham, Moses and Joseph - seen as prefiguring the person of Christ himself. The saving work of Christ is also represented by its prefiguration in the offering of Melchisedech and Abraham's intercession on behalf of Sodom. Christ's own life and death are also represented in the mosaics. In keeping with the spirit of the Oxford Movement, saints and fathers of the Church are also represented. As you leave the chapel, it is the scene of the last judgement that faces you above the door.
The underlying principles of the decoration are profoundly liturgical, and oriented to the celebration of a worship which renewed in the Church of England its catholic sense. The inspiration for the decoration of the Chapel is John Keble's The Christian Year - those more familiar with John Keble than I am will appreciate this link.
The only other place I have seen anything like this is the Benedictine Abbey of St Hildegard, at Eibingen, across the River Rhine from Bingen. The guided tour of the Abbey Church indicates clearly how the decoration of the Church is designed to celebrate the living presence of God with his people through the course of history.
The experience of sitting in the nave at Eibingen, somewhat gobsmacked by the decoration of the Church came strongly to mind as I sat in Keble College chapel. Both churches are well worth a visit.
