The river flowing placidly on this beautiful day on Saturday 24 November is the Arno, near Le Sieci, a hamlet of Pontassieve, above Florence. The colours are those of autumn and evidently the amateur cameraman Luciano Osti intends to render with this amateur film the peaceful climate that this landscape evokes, with few human figures, the fishermen filmed from afar, a few solitary boats, the architectural forms of the village and the ancient castle and a few details of nature, above all the trees painted in pastel by the season and the olive trees illuminated by the sunlight, the reflections on the water and the flowing river. Osti, always attentive to the passing of the seasons, rarely uses colour film (but for this amateur 8mm film the choice is apt) and rarely leaves his city, Bologna, whose urban transformations and hectic traffic at the same time, documenting what is disappearing and the new that is advancing. Instead, this Tuscan is a landscape that seems intact, constant in its apparent slowness, far from the chaos of the city. It seems unchanging, but the water flows and 'you will not film the same river twice', the philosopher would say.
