The older nasoni have a dragon's head at the end. Newer ones have a smooth torch decoration. Some older ones have three spouts while most have one. Please don't be put off by the rust or minerals built up at the base of the nasoni--the water is perfectly pure. All of the nasoni bear the shield of Rome with SPQR emblazoned on it. This is from the Latin phrase from Ancient Rome: Senātus Populusque Rōmānus (The Roman Senate and People). Today, this is the official emblem of the modern Roman government.
