premise: The fascinating exhibits include a section of the massive chain that the Byzantines used to stretch across the mouth of the Golden Horn to keep out enemy ships , as well as captured enemy cannon and military banners , the campaign tents from which the Ottoman sultans controlled their armies , and examples of uniforms , armour , and weapons from the earliest days of the Empire down to the 20th century .
hypothesis: The exhibits are dull and boring , everything is made from paper , and there is nothing about the Bzyantines .
