In his book "Julian," Gore Vidal explores themes of power and perception through the lens of historical narrative. The quote, "On the throne of the world, any delusion can become fact," reflects the idea that those in positions of authority can manipulate reality to fit their narratives. This suggests that leaders can distort truth and influence public opinion, blurring the lines between what is real and what is fabricated.

Vidal's work emphasizes the disconnect between actual history and the stories crafted by those in power. By examining the character of Julian, he illustrates how the ambitions and beliefs of rulers can shape societies, often leading them to accept falsehoods as truths. This commentary on the nature of leadership and belief raises questions about the significance of understanding history and the role of narrative in shaping our world.
