"One would like to say de mortuis nil nisi bonum, but a friend may be allowed to offer a little criticism. He was not always as receptive to new ideas as he should have been, and as an historian was not always at ease with the physical remains of the period he studied."

“I have happy memories of the Round Room at the Public Record Office in the 1950s, with the large fire occasionally made up by one of the supervisors, Allen Brown.

“Nowadays, to call anything ‘medieval’ is itself an insult, while to call it ‘feudal’ is ten times more offensive; and if castles are not seen merely as vaguely romantic ruins, they are seen through an idiot haze of bold, bad barons, deep and dismal dungeons, and boiling oil. At best their context is thought to be almost exclusively military, and that too is against them, since in our time one must be against warfare as one used to be against sin.”
