Albrecht Dürer, Rhinoceros, 1515

The first video, from the Clark Institute in Williamstown, Massachusetts, provides a brief introduction (2:33) to this famous image.  The second and third videos from the British Museum jointly provide a more extended account (29:13).  An audio commentary on Durer's rhinoceros is also the subject of the 75th episode in the British Museum's History of the World in 100 Objects.
