But what we are going to discuss today is how the port of London was discovered and what we discovered about it. Now if you look at the historical records of Roman London, there is only about 14 actual references to London in antiquity I contemporary references. And all those only one is in the first century, there are none at all at the second or third century. There is only one in the late third century and there is four in the fourth century. So if you are a historian trying to write the history of Rome in London, it's really difficult. You don't have much data, you're going to depend on the archaeological evidence, the material evidence of the port and indeed the town to have any understanding of what happened then. And so, what we're looking at here is how we discovered about the port of London, there is no historical documentations, no customs books, no terrorists, or idea of the taxes. We have to understand the port entirely from the archaeological evidence. So that's what we are going to do today. So, if we move on to the next slide, I love life streaming. Thank you very much.
