This is a black and white woodcut illustration of a sea monster, likely from an old book or bestiary. The monster is depicted as having a serpentine body with a large, bulbous head. It appears to be emerging from the water, with its upper body raised and its lower body partially submerged. The head has a beak-like mouth and what appear to be small, beady eyes. The body is covered in scales or textured patterns, and there are small fins or appendages along its sides. The monster is surrounded by patches of grass or vegetation, suggesting a coastal or marshy environment. Below the illustration is a block of text in an old-fashioned typeface, likely French, with several lines of script. The text is centered and appears to be a caption or description of the creature. The entire image is framed by a decorative border with a repeating pattern of stylized leaves or foliage.
