PRINCETON – Fly out of London’s Heathrow Airport and you may pass over a grassy field called Runnymede. Eight hundred years ago this month, it offered a colorful spectacle, dotted with the tents of barons and knights, and the larger pavilion of King John of England, looking like a circus top with the royal standard fluttering above.
普林斯顿—飞离伦敦西斯罗机场（Heathrow Airport）时，你可能会飞越一片叫做兰尼米德（Runnymede）的草地。八百年前的这个月，这片草地色彩斑斓，遍布着男爵和骑士的帐篷，更有规模更大的英格兰约翰王（King John）的王帐，看上去像是飘荡着王旗的马戏团。
