The Mouth of Hell (Hellmouth), Chapelle Notre-Dame de Kergoat

The composition is dominated by the oversized, gaping jaws of a serpentine creature whose throat forms the entrance to Hell. Inside, a blue-skinned, feline-eared demon stands over a cluster of naked, tormented figures, brandishing a large spiked mace. Another smaller, red-skinned, grinning demon face peers out from the upper right of the maw. The background is a flat, deep red, suggesting the 'Lake of Fire' or the infernal abyss. The figures are rendered in a distinct 16th-century style with lead cames demarcating the colored glass segments, emphasizing the jagged teeth of the beast and the twisted, anguished expressions of the damned.

This image is a quintessential example of the 'Hellmouth' iconographic motif prevalent in late medieval and early modern Christian eschatology, often featured in Last Judgment scenes to visualize the eternal punishment of the damned. It reflects the vivid, literalized theological concepts of the afterlife found in popular sermons and mystery plays of the period.
