This window (c1550) presents a sequence from the Life and Martyrdom of St Agnes, the young Roman virgin celebrated for her steadfast refusal to accept a pagan suitor and her unwavering confession of faith. Produced by a Rouen workshop in the early sixteenth century, the window follows the typical Saint-Ouen format: narrative scenes set beneath tall Gothic canopies, framed by alternating architectural and landscape elements.

At the far left, Agnes stands in prayer while a richly dressed suitor kneels imploringly before her. This scene encapsulates the opening of her legend, in which Agnes rejects the advances of a noble youth, declaring that she has consecrated her life to Christ. The dignity of her stance contrasts with the suitor’s pleading posture, underscoring her resolve.

In the next panel, the suitor has collapsed or fallen backwards, struck down by divine intervention. This moment represents the miraculous affliction that befalls him after he attempts to force Agnes or presses his suit too boldly, an episode included in several medieval versions of her Passion.

The central panel shows Agnes being arrested. Soldiers or officials seize her arm and lead her away, marking the point at which the Roman authorities intervene, either at the suitor’s instigation or because of her openly professed Christian faith. The architectural backdrop reinforces the judicial setting.

To the right, Agnes is shown at the moment of execution, with an assailant preparing to stab her from behind at the base of the neck. This reflects the tradition that, after surviving earlier torments unscathed, she was finally put to death by the sword. The tight composition heightens the sense of imminent violence.

The rightmost panel concludes the cycle with Agnes being lifted heavenward by angels. Her body is supported gently, her posture peaceful, marking the transition from martyrdom to heavenly glory. The scene corresponds to the widespread belief that her soul was carried directly to God, a motif frequently used to affirm the sanctity of virgin martyrs.

Together, these panels present a concise yet vivid account of St Agnes’s purity, her divine protection, and her triumphant entry into heaven. Although restored and recomposed over time, the sequence retains key elements of the sixteenth-century Rouen style, saturated colours, expressive gesture, and densely architectural canopy work, ensuring the window’s continued significance within the broader hagiographic cycle of the south aisle.
