This is an illustration from a medieval manuscript. It depicts a large, pale green fish lying on a bed of red, flame-like spikes. The fish has a rounded body and a long, curling tail that is a mix of brown and white stripes. The spikes below the fish are a vibrant red with darker outlines, resembling flames or thorns. The background is a golden-brown color. The image is framed by a decorative border consisting of a repeating pattern of dark, arrow-shaped motifs. The style is characteristic of medieval illuminated manuscripts, with flat colors, simple shapes, and a focus on symbolic representation rather than realistic depiction.
