Heliopolis is a distant city, projected into a future dominated by technology in an omnipervasive way. A theater of human passions in which fragments of our time converge, the city is shaken by a clash of power at the top of the regime. Venerable traditions and ancient communities are swept away by the invincible weapons of the army, but the technological apparatus, which reaps its victims in the name of progress, also knows how to preserve the memory of the past, thanks to powerful equipment that archives the entirety of human knowledge. Commander Lucius, the novel's protagonist, struggles with the contradictions of a sick utopia, oscillating between the cult of discipline and his attraction for Budur, an elusive and haughty woman. The fact that Ernst Jünger predicted the planetary rule of technology (in his The Worker, 1932) and the unification of Europe as the community of the future ranks him among the most significant European thinkers. Heliopolis is one of Jünger's most significant works, a novel that talks about the relationship between time (tradition) and the moment in which the world is today (modernity), and about the conflict between these two times. Jünger advocates the opinion that the more the world develops (the age of technology), the more a person becomes a slave to his work and his ideas. This is a book about modern humanity's need to rebel in order not to be created and lost in overabundance.
