Nezahualcóyotl, a suburb of Mexico City with a million inhabitants, is one of the most densely populated and at the same time poorest suburbs in the world. By applying the Nazca-lines to roof tops and streets in years of work, Oe inscribes the heritage of an ancient Peruvian culture into the urban structures of a nearly boundless conglomerate of present-day civilization, the scale of which only becomes apparent from great heights- the same height that is necessary to decipher the Nazca-lines as the outlines of enormous zoomorphic figures.
