Grisaille-painted glass, highlighted with silver yellow, lead-glazed, depicting Saint Catherine of Alexandria. She is shown with the traditional attributes that identify her: the sword and Emperor Maxentius at her feet. Her face, rendered in grisaille with fairly fine modeling, is surmounted by a halo. In the background is the cogwheel used in her martyrdom.
The medallion is set within a diamond-patterned glass panel.
