Picture this. Across an open field, two men on horseback charge at each other. Their steel armor shines brightly in the blazing sun.
One of them is trying to protect the castle on the hill. The other wants to take over the castle. All around them, men fight with swords. Their blades clash and clang as they 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 and charges at another warrior. The battle goes on.
Let’s leave our modern world behind. Forget your cell phone and TV. Let’s go back in time almost a thousand years, to Europe in the Middle Ages. Back then, knights—fighting men on horseback—protected the castles of the rich. Our first stop is the castle on the hill.
