Il cielo sopra Roma : I luoghi dell’astronomia = The sky above Rome : The places of astronomy

Astronomy in Rome has always been there, but a little hidden: it was in the palaces, in the churches or, better, above the churches, speculas scattered along a path that few know by now. Intrigued and frightened, the Romans witnessed the burning of Giordano Bruno in a familiar corner of Campo de 'Fiori, but they probably didn't quite understand what guilt he was accused of. They certainly did not think that he was a philosopher and a scientist who had tried to imagine what the world was like.
