" The name Erdosain gave to this mood of dreams and disquiet that led him to roam like a sleepwalker through the days was “the anguish zone”. He imagined this zone floating above cities, about two metres in the air, and pictured it graphically like an area of salt flats or deserts that are shown on maps by tiny dots, as dense as herring roe. This anguish zone was the product of mankind’s suffering. It slid from one place to the next like a cloud of poison gas, seeping through walls, passing straight through buildings, without ever losing its flat horizontal shape; a two-dimensional anguish that left an after-taste of tears in throats it sliced like a guillotine. "
