An investigation of the urban area of Gallarate, presented at the MA*GA museum and edited by Emma Zanella and Alessandro Castiglioni. The momentary horizons of the title are what a town of that kind offers: not a landscape that stays still to be looked at but a line that shifts with every street corner, every new building and every demolition. The work led to the establishment of a Mario Cresci collection inside the museum's permanent holdings.
