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. And even if it had come in, there was nothing for it to hurt, for the walls were of rough stone, and the floor of tiles. There was a fire at each end of this great dark apartment, but there were no chimneys over the ample hearths, and the smoke curled about in thick white folds in the vaulted roof, adding to the wreaths of soot, which made the hall look still darker.
