On a bright autumn day, as long ago as the year 943, there was a great bustle in the Castle of Bayeux in Normandy. The hall was large and low, the roof arched, and supported on thick short columns, almost like the crypt of a Cathedral; the walls were thick, and the windows, which had no glass, were very small, set in such a depth of wall that there was a wide deep window seat, upon which the rain might beat, without reaching the interior of the room.
