Above Biella, there is a sanctuary called Oropa. On the roof of the sanctuary, there is a small weather station. Every day, someone records the measurements indicating what happened during the day. From these measurements, he can predict what will happen the next day. This is a weather report. In the corridors of the sanctuary, people come to leave crosses, drawings, soccer jerseys as offerings. Below the sanctuary, it is the beginning of the city. People carry the vegetables they have just bought. Almost every day in the city, a gate repairer puts papers with the words MEK POL CONTROLLO on the gates of the whole city. If the weather is good, you can pick them up. If it's raining, you can't. Between the papers and the sanctuary, there is the river. Sometimes it is high, sometimes it is low. There are papers almost every day, but you can't predict. Sometimes there are, sometimes there aren't. Andréa Spartà started to collect all of this. Mek Pol Controllo's papers, a certain percentage of his groceries, items found left and right, items bought second hand from locals, including beach mats and mosquito repellent lamps. It's a weather report.
