The transmission of ideas between cultures within the ancient and medieval periods, as well as within the modern, are key aspects to the whole project. They are also very sensitive and difficult phenomena to identify, let alone measure and assess. A combination of very broad brush-strokes and very detailed work is necessary.

We do this both in the round and in detail!
