This is a medieval manuscript illumination depicting a seal with a human head. The seal is brown with dark spots and has a streamlined body and flippers. Its head is distinctly human, with curly hair and a somewhat grim expression. The seal is shown swimming in wavy, light-brown water. The image is framed by a decorative border consisting of a repeating pattern of small, stylized shapes in shades of blue, brown, and gold. The background is a textured gold color. The style is characteristic of medieval art, with simplified forms and a focus on symbolic representation rather than realistic depiction.
