Mark was the last person to have taught me Medieval History in school, and it is because of his animated retelling of events such as the Battle of Hastings - of which I have fond memories - that I decided to give some Medieval History modules a go at University. Flash forward 15 years, and in one week's time I shall be submitting my PhD in Medieval History for examination. Although I'd never have known at the time, he set me on this path, and I owe him my utmost thanks.
