This is a medieval illustration depicting a large flea. The flea is rendered in dark ink with a detailed, segmented body and long, spindly legs. It appears to be leaping or running across a ground of short, green grass. On either side of the flea are stylized green plants with red stems. The background is a warm, golden-brown color. The entire image is framed by a decorative border. The border consists of a series of repeating, stylized patterns in red and gold, creating a rectangular frame around the central scene. The style is characteristic of illuminated manuscripts, with flat colors, bold outlines, and a focus on symbolic representation rather than realistic depiction.
