On an ordinary day with habitual rhythms, a swarm of peaceful citizens, not human but pigeons, emblem of our urban glimpses, stroll in the clearest serenity, between roofs, cornices, tiles and porches. Time is marked by a feminine and maternal ticking, marked by a large clock. When the stroke of 10.25 coincides with the explosion of a bomb, coming from the watch itself, introduced by a dark hand. It is panic. Citizen-pigeons flee in dismay. A chilling silence follows, awakened only by the echo of the crows, which like shadows spread over the seraphic city, now the defenseless victim of a brutal and frightening act. Polondo: Everything is black, terror has closed everyone in the house. When an isolated citizen, retracing and reciting the "Pasolinian" I KNOW, tries to defeat terror. The city gradually wakes up, with courage. Even if the pigeons do not know the real authors of the massacre, they know that to overcome anguish it is necessary to come out into the open: living helps not to die. The square is infected with hope, and in the background, finally, not only roofs and cornices, but also the emblems of Bologna, symbol of a land wounded by terrorism in the 80s, but never completely defeated. On San Luca, San Petronio and on the two towers the fireflies shine, which can finally return to shine protected from the clamor, far from worry. Just like fireflies, Bologna also takes possession of life, with all its commonplaces and its mythical and heroic characters. 40 years have passed from the bomb to the central station, the years of lead on our nation are long gone, but, today as then, each of us can be the victim of anguish for the future. An unforgettable Lucio Dalla then invites us not to fear, the wait can still bring to light. From the street artists, together with the university students, passing through the artisans and delicatessens, without neglecting the merchants and benefactors, they all huddle together around the message: BOLOGNA DOES NOT DENY. Bologna is not forgotten, without fear, tomorrow.
