CM: Thanassis Rentzis created the Gray Field series in a single day using the traditional press of Nikos Vozikis Printer. To produce these works Rentzis used the roll, the texture of wood and paper on the paper. The works were produced in a sequential manner, without preliminary work. Rentzis recounted "I was creating one part and wondered how it was going to continue. It was like composing objects in an empty room. I had in mind an image of the city with its thousands of stimuli becoming one, much like like a crowd of people without character become a mush." In his book entitled Die Grosstadte und das Geistesleben (The Metropolis and Mental Life) Georg Simmel (1858-1918) recorded in 1902 his observation that Modernism has changed dramatically the scale of the urban landscape. It gave birth to a new experience of the city very different from that which prevailed until then, which he called 'shock of the metropolis'. The shock comes from the "intensification of nervous stimulation caused by the rapid and continuous change of external and internal stimuli". In Gray Field volume is absent. Herewith Rentzis represents the size and pace of succession of such stimuli that flatten the impulses and impressions.
