The Fountain of Neptune is a fountain in Florence, Italy, situated on the Piazza della Signoria, in front of the Palazzo Vecchio.It was commissioned on the occasion of the wedding of Francesco I de' Medici with grand duchess Johanna of Austria in 1565. The Neptune figure, whose face resembles that of Cosimo I de' Medici, was meant to be an allusion to the dominion of the Florentines over the sea. The figure stands on a high pedestal in the middle of an octagonal fountain. The pedestal in the middle is decorated with the mythical chained figures of Scylla and Charybdis. The statue of Neptune is a copy made in the nineteenth century, while the original is in the National Museum.
