This is a medieval illustration of a fantastical creature resembling a fish with legs. The creature is depicted in shades of purple and gray, with a long, streamlined body and a pointed snout. It has a prominent dorsal fin and a tail fin, but also possesses four legs with clawed feet, suggesting it can walk on land as well as swim. The creature is shown emerging from a wavy, green body of water. The background is a textured gold color. The image is framed by a decorative border consisting of a blue band with repeating geometric patterns and a narrow orange band with small circular motifs. The style is characteristic of illuminated manuscripts, with flat colors, simple lines, and a focus on symbolic representation rather than realistic anatomy.
