What are dreams made of? What could Ouranupolis, an immaterial, aethereal city, look like? A city experienced by its residents aw a “prison”? The challenge for the set design was to find a materiality that could create this dual world on stage: the world of dreams and Arpatilaos’ prison. The aim was not to restrict imagination triggered in young and older audience by Evgenios Trivizas’ words with a stiff, representational image. Searching for a tough yet flexible and transparent materiality, I came to decide on using barbed wire as the main material of the set. Barbed wire is used to define areas, fence off, and imprison, but it is also malleable, penetrable and transparent. In fact, it does restrict, but not vision. This material was given various shapes, different shades of colour, and along with pillows and feathers formed our own Ouranoypolis on stage.
