For example, take the case of the ancient prophecy that said Rome would eventually be destroyed by fire. Some historians believe that this prophecy played a role in the city's decline, as people began to lose faith in their leaders and institutions. They may have seen the prophecy as a sign that Rome was doomed, and as a result, they became more inclined to rebel against the government or become complacent about the city's fate. On the other hand, the prophecy could also have simply been a coincidence, or a lucky guess by the person who made it.
