This is a medieval illustration depicting a knight slaying a dragon. The scene is set against a golden-yellow background. The knight is clad in full armor, including a helmet, and is in the midst of striking down the dragon with a raised sword. He holds a red shield with a golden emblem. The dragon is a serpentine creature with green scales and a long, winding body. It appears to be in a defensive posture, but is clearly being overcome by the knight's attack. The illustration is framed by a decorative border with repeating patterns. The style is characteristic of medieval manuscript illumination, with flat colors, stylized figures, and a focus on narrative.
