Apart from the donor/signature panels in the lowest register, a Tree of Jesse runs up the central column, whilst the infancy of Christ occupies the outer panels - the story of Christ's incarnation winding its way around the story of his ancestry. As with the other turning bays in the apse, the three oculi in the upper tracery are filled with episodes from an unrelated story - in this case that of Abraham's sacrifice of Isaac (a story often paired with Passion scenes, especially the carrying of the Cross, but which has no obvious exegetical correlation to the Infancy of Christ).

The distinctive Tourain palette, with its bold use of light green and yellow glass, is particularly noticeable here. So, unfortunately is some rather clumsy modern re-leading which was done with unusually wide lead cames, disrupting the design and reduces the light transmission which should have been such a feature of these turning bays.
