This is a close-up of a medieval manuscript illumination. The central focus is a stylized, light blue fish depicted with a somewhat elongated body and prominent fins. It appears to be 'walking' or moving across a wavy, green surface that represents water. The fish has a detailed head with an open mouth, suggesting it might be roaring or vocalizing. The fish is framed by a rectangular border. The border consists of a gold background with a red and blue patterned frame. Above the fish is a line of dark, gothic script in an old language. The overall style is characteristic of medieval illuminated manuscripts, with flat colors, stylized forms, and a focus on symbolic representation rather than realistic depiction.
