I am descending a stone wall down a ladder made of roughly-hewn logs. I am careful not to lose my grip. Made of large chunks of stone, the wall is very high. I am close to the bottom of the wall when a Roman soldier appears on top. He is hurrying me away with a bare sword. Wearing an elaborate helmet and a coat of mail, he is telling me that the execution is about to begin. Today they are executing naughty children. Chopped off by the sword, their heads will fall to the bottom of the wall. By the time I am safely away from the ladder, I am hastening on my way. I expect to hear a thud behind my back, but I wake up before the first execution. As I am opening my eyes, I feel relieved to have missed that gruesome thud.
