In the South Oculus, fourteen original ornamental panels survive, the remainder is a reconstruction of the iconographic scheme by the younger George Austin, based on the remaining glass in the opposite window. At the centre of the window Christ and Ecclesia are depicted within the square. They are surrounded by Matthew, Mark, Luke, and John, and faith, hope, and charity with humility within the inner circle. This is surrounded by the 12 Apostles. The window is the opposite to the north oculus which depicts the old covenant, the north side of the building being associated with the past and darkness.
