The Lamentation over the Dead Christ is an openwork bronze relief sculpture of c. 1455–1460, produced in his old age by Donatello and now in the Victoria and Albert Museum in London.
[1] It is generally thought to be a test piece for the bronze doors for Siena Cathedral, a commission from the artist that was contemplated, but never completed.
In this case it would date from 1457-1459.
It may be the bronze of the subject recorded as being in the cathedral's possession in 1639.
