France 2009 Region of Aquitaine - the origin of modern rugby?

The French Post released in August a series of regional sheetlets with 10 self-adhesive stamps each featuring regional specialties. The stamp shown above is from the sheetlet for Aquitaine. The description for it listed "soule" or "sioule" as the ancestor of modern day rugby. I googled it, and discovered that "soule" is still being played in France, especially in Normandy, and there are almost no rules for it, one just have to bring the ball across the goal line, and there can be any number of players on either side. The game is supposed to been played more than a thousand years ago!
