The Chapel window has four main sections (lights) and eight small sections across the top (tracery). The tracery panels are a mix of grapevine and diamond patterns, with the grapevines likely to represent the wine drunk at the Eucharist, Christ's last supper with his disciples.
The lower section of the lights contain an elaborate pattern of sunflowers, blue flowers and pomegranate flowers; these appear to be purely decorative, without the theological significance of the tracery grapevines.
Each of the main lights depicts a different figure
- A woman kneeling in prayer with an angel carrying her heraldic shield above her
- The Throne of Mercy - God the Father supporting Christ crucified on the cross
- The Pietà - Mary, mother of Jesus, holding Christ's crucified body
- A mirror image of panel number 1 but with different heraldry
The Throne of Mercy and The Pietà, along with the Eucharist vines in the tracery, all pick up devotional, sacrificial and redemptive themes within the Christian faith which suggests that whoever commissioned this window, highly valued these themes.
Anyone who has ever visited Burton Constable Hall will know that the entire Hall is covered in heraldry. The chapel itself has 16 armorial shields painted around the top of its walls. However, the two heraldic shields in the window do not match any of the heraldry in the Hall.
Instead, the window's heraldry is made up of the family emblems of the Fettiplace family (left hand shield) and of the Waryng and Englefield families (right hand shield, split horizontally). These three families are from the south of England, previously Berkshire but now Oxfordshire, and have no known familial or political links with the Constables. So why is their heraldry in a window in Burton Constable Hall?
