The Archangel Michael raises his arm, sword in hand, poised to slay the devil. The battle between them takes place against an extraordinary landscape. With his golden hair, gilded wings, and flowing robes, the archangel looks victorious as he leans over his foe. Satan-a scrawny, winged creature with talons and horns-squirms on the ground, flames licking his belly.
Sinuous lines of glass paint-especially in the archangel's swirling robes-echo the pane's round shape. Stippling and scraping away the paint allowed light to pass through, enhancing the image's three-dimensional qualities. On the panel's other side, which would have faced the building's exterior, the artist painted the rich accents of silver stain, creating tones from deep orange to brilliant lemon yellow.
This roundel was likely set in a clear glass window in a private home or chapel. By this time, roundels had become widely affordable and were nearly mass-produced. Subjects varied and were often secular, but scenes such as this one were meant to encourage Christian devotion.
