Since the Middle Ages there has been evidence of use of the marsh system as an internal navigation route. The Fucecchio-Usciana marsh system was an important waterway link between Pisa and Florence through the Valdinievole. In 1780 there were still more than 50 port facilities, often consisting of simple landings, used for various types of watercraft: from the small nocciolelli, which later became barchini (small boats), to larger ones that loaded goods, such as barconi (big boats) and navicelli (small ships). Today only the barchino remains, a small typically flat-bottomed boat, blackened by pitch, used mainly by hunters. In the famous 1473 Paesaggio (Landscape) by Leonardo, according to a recent interpretation, what we see depicted at the center would be a foreshortening of the Fucecchio Marshes, on which it seems we can make out one or two small watercraft with their typically curved bows. The 1473 Paesaggio dell’Arno (Arno Landscape) will be on display in the exhibition entitled Alle origini del Genio (At the Origins of the Genius) (Museo Leonardiano, Vinci, 15 April - 15 October 2019). Further, in the Museo di Fucecchio, there is a painting from the mid-15th century, by Lo Scheggia, Masaccio's brother, depicting a little marsh noccoletto (small barge): the Madonna con il Bambino in gloria e santi (Madonna and Child in glory with saints). The Virgin with the infant Jesus, framed by the violent red of the cherubs, is flanked by the figures of four saints. On the left side, San Sebastiano is positioned on a spur of land, while San Lazzaro and Santa Marta and Santa Maddalena are standing on a typical marsh vessel, the noccolo, or small, flat-bottomed boat. This is an allusion to the journey of the three saints who, according to tradition, arrived in Provence from Palestine.
