Thanks for re-sharing the work of William Bateman Fagan. On the door, the carved panels show the development of science and technology. The panels on the left show stone age technologies and show the construction of a basic tented home starting with building the frame onwards to completion. The final panel includes the completed tent with Stonehenge being seen in the background. The panels on the right hand door show contrasting modern industrial scenes. https://victorianweb.org/sculpture/fagan/index.html
