The original is a tympanum, from the 'Prior's Doorway' by an unknown sculptor in stone, dated ca. 1140, Ely Cathedral, Ely, Cambridgeshire, England. An extensive cast collection was also assembled for the Crystal Palace and from shortly after 1900 energetic attempts were made to bring the best of these to South Kensington and so form a truly national museum of casts. But despite these efforts none of the casts left the Crystal Palace until 1938 when, following the disastrous fire, the few surviving examples came to the Museum.
