This is a medieval illustration, likely from a manuscript. It depicts two fish swimming in water. The fish are stylized, elongated, and colored in a pale green with darker markings suggesting scales. They are positioned curving upwards, as if leaping or swimming energetically. The water is represented by wavy, brown lines, creating a sense of movement. The illustration is framed by a decorative border. The border consists of a rectangular frame with a repeating pattern of vertical lines and stylized floral or leaf-like motifs. The frame is colored in shades of brown, blue, and gold, adding to the overall medieval aesthetic. The background is a warm, golden-brown color.
