In recent years there has been considerable historical discussion about the exact location of Bosworth field. It now seems that there is similar uncertainty about the location of the Battle of Hastings. This report from the BBC explains the uncertainty, and asks if it matters.
There is a link here to the earlier report on the Black Death. It is tempting to see the History of the Middle Ages as done (and dull ?). Nothing could be further from the truth. For me the very term is unhelpful. It is a huge 400 year period, which should not be generalised. Moreover, our understanding of it is still evolving.
