This tall, single-figure panel from the east window of Gloucester Cathedral depicts St Margaret of Antioch, rendered in the elegant linear Gothic style characteristic of mid-14th-century English glazing. She stands beneath a simple architectural canopy, set against a rich ruby-red ground that accentuates the pale modelling of her robes.

St Margaret is shown holding a cross-staff, the emblem with which she overcame the dragon. Her other hand rests lightly on a book or scroll, signalling her steadfast faith. At her feet appears the dragon, rendered here as a sinuous creature with a curling tail, its head turning upwards in defeat. The saint’s calm expression and slightly tilted head convey the gentle self-possession often found in English female saints of this period.

Her robe is ornamented with golden bands and clasps, the yellow stain used sparingly but effectively to highlight the hem and girdle. Architectural side shafts, with alternating white, purple, and yellow-stained elements, frame the figure and help integrate the panel into the larger scheme of the window.

The glass belongs to the important body of mid-14th-century glazing at Gloucester, contemporary with the rebuilding of the choir after the 1330s. Its mixture of refined draughtsmanship, saturated colour, and decorative detailing reflects the sophisticated glazing workshops active at the cathedral in the decades before the Perpendicular style emerged fully.
