Symbol of Sassari and a unique monument in Sardinia, included in the 'Fountains of Italy' series of stamps, it contains the metaphor of time that flows like water, symbolized by twelve mouths, the months, and four statues, the seasons. Outside the ancient city walls, near the bridge of the same name, the fountain of Rosello was built at the beginning of the 17th century, in late-Renaissance style, giving a name to the district that arose around 1930, where the Masedu museum and the basilica of Sacro Cuore are located.
The sculptural complex is made up of two overlapping rectangular blocks that are linear, simple and white and dark grey colours, enhancing the lions' heads from which water flows. The statues representing the seasons rest on the mouths of dolphins: a girl with a garland of flowers (spring), Hercules with a crown of grapes and a bearskin (autumn), an old man resting (winter), a woman with ears of corn (summer), the only original, kept in Palazzo Ducale. The other three were destroyed during anti-feudal uprisings (1795) and were recreated thirty years later.
