The ability to project a virtual vision on the world and give it physical form sets the human apart. By shaping his surroundings at will, the human holds considerable power not only on the environment, but -on fellow humans and the world at large. The thesis discusses the different shapes the horror of architecture takes. Told as a loose history of civilization, it constructs a theory of horror from the primal confrontation to nature, lingers on the oppressive walls of contemporary society, and projects a future of labyrinthine sentient buildings. A chimera one part asterochronic collage and four parts picaresque novel, the resulting document recalls the failure of the thesis as building to dwell on the indefinable, uncontainable nature of horror, a dark internalized version of the world with an undertone of settled accounts.
