This is an illustration from a medieval manuscript, likely a bestiary. The central figure is a fantastical creature resembling a turtle or tortoise, but with a distinctly reptilian head and tail. It's depicted in profile, with a large, rounded, pale blue shell that dominates the image. The creature's body is a reddish-brown color, and it has small, clawed feet. The creature is resting on a textured, brown ground that appears to be made of small, rounded shapes. The illustration is framed by a decorative border. The top and bottom borders consist of a repeating geometric pattern of triangles. The side borders are composed of a vertical series of small, linked 'T' shapes. The background is a golden-yellow color.
