This is a medieval illustration of a sea monster. The monster is a reddish-brown color and has a large, gaping mouth filled with rows of teeth. It has several tentacles extending from its body, and its eyes are large and round. The monster is depicted in a body of water, which is represented by wavy green lines. The illustration is framed by a decorative border, which is blue with gold accents. Above the image is text in an old script.
