Even though the Egyptians were warlike,they found time for peaceful games．Before long they had developed a number of ball games,each with its own set of rules．Perhaps they played ball more for instruction than for fun．Ball playing was thought of mainly as a way to teach young men the speed and skill they would need for war.
