Albrecht Dürer illustration of an Indian Rhinoceros based on his woodcut from the year 1515. Interestingly, Dürer himself actually never got to see a real rhinoceros, and his illustration of this exotic animal is based on what he imagined one might look like with only a basic sketch and a previous written description to go by. Although the drawing has morphological mistakes such as the horn on the animal's shoulder, it was widely used and became one of the most well-known animal images.
