As one of the oldest of competitive pastimes, the sport of hockey dates back well before the Ancient Olympic Games. In medieval Europe, pictures of men playing a game with hooked1 sticks appear on stained-glass windows2 at both the Canterbury3 and Gloucester4 cathedrals5. It became so popular by the Middle Ages that it was banned6 in England for a time because it interfered with the practice of archery7, which was the basis for national defense. The name hockey probably derives from the French hocquet, or shepherd's crook8 and refers to the crooked9 stick.
