A perfect autumn day. Above, the clear sky of Italy; below, a grassy plain, sloping gently down from the brown cliffs and ruined ramparts of old Veii--the city of the ancient Tuscan kings. In the background, under the shade of the oaks, a dozen waiting attendants; and here, in the open space before us, three trim and sturdy Roman youths, all flushed with the exercise of a royal game of ball. Come, boys and girls of to-day, go back with me seventeen and a half centuries, and join the dozen lookers-on as they follow this three-cornered game of ball. They call it the trigon. It is a favorite ball-game with the Roman youth, in which the three players, standing as if on a right-angled triangle, pitch and catch the ball, or pila, at long distances and with the left hand only. It is not so easy as you may think. Try it some time and see for yourself.
