Can you guess what it is yet?

When I'm exhibiting my models I like to display an information sheet alongside, with a photo showing the model that it refers to.
I needed a new one and thought it would do for today's blip as well.
For anyone interested it's a 1/12 scale model of a Beotian seige engine from about 55BC. The cauldron contained a fire which was used to burn down the city gates.
