The Tomb of Mabilia de Murdak (also spelled Mabilla or Mabila) is a small 14th-century medieval monument. The tomb is part of a collection of stone memorials in the north chapel (or Gayton Chapel), which includes effigies of local nobility tied to dramatic family events, such as murder and pilgrimage.

These two stained-glass panels from the choir clerestory of St Ouen form a paired narrative of the Massacre of the Innocents, rendered in the incisive and highly expressive manner characteristic of the early 14th-century Norman workshops. Though each panel stands within its own Gothic architectural frame, complete with gabled canopies, foliate bosses, and alternating bands of strong primary colour, the scenes are conceived as a continuous episode of violent disruption, unfolding across two moments of the same biblical tragedy.

These two mitred abbots are from about 1327-1330, and can seen in the tracery of the east window of St Nicholas, Stanford-on-Avon, Northamptonshire.
