Whilst wandering through the Babylonia galleries in the British museum I was struck by this sculpture.

The sculpture is about 6 feet tall. Initially I thought that the sculpture was complete but on reading the information card I discovered that what I was looking at was the remains of a larger sculpture, the indentations in the rock were caused by people using it as a rubbing stone.
Either way, it is a very beautiful stone.
