Imagine seeing two men on horseback charge at each other across an open field. Their steel armor shines brightly in the blazing sun.
One of them is trying to protect the castle on the hill, while the other hopes to take over the castle. All around them, men are fighting. Their swords make clanging sounds as the blades strike each other. At last, the razor-sharp point of one sword pierces the armor of the other knight. Badly wounded, that man falls from his horse to the ground. The victor turns away, charges at another warrior, and the battle goes on.
Let’s leave behind our world of cars, televisions, computers, and cell phones. Let’s go back in time almost a thousand years, to Europe in the Middle Ages. During that time, knights—fighting men on horseback—protected the castles of the wealthy. Our first stop is the castle on the hill.
