This is a medieval illustration of a fish with legs. The fish is depicted in profile, standing on a patch of green ground. It has a large, silvery-white head with a slightly downturned mouth and a prominent eye. Its body is a mix of green and brown scales, and it appears to have four legs with small, clawed feet. The background is a golden yellow, and the image is framed by a decorative border. The border consists of a red band with a repeating pattern of small, stylized leaves or foliage, and a blue band with a repeating pattern of vertical lines. The style of the illustration is characteristic of medieval manuscripts, with flat colors, simple shapes, and a focus on symbolic representation rather than realistic detail.
