Fontana Dei Quattro Fiumi - Design

Design

Bernini's design was selected in competition. The circumstances of his victory are described as follows in Filippo Baldinucci's The life of Cavaliere Bernini (1682):

So strong was the sinister influence of the rivals of Bernini on the mind of Innocent that when he planned to set up in Piazza Navona the great obelisk brought to Rome by the Emperor Caracalla, which had been buried for a long time at Capo di Bove for the adornment of a magnificent fountain, the Pope had designs made by the leading architects of Rome without an order for one to Bernini. Prince Niccolò Ludovisi, whose wife was niece to the pope, persuaded Bernini to prepare a model, and arrange for it to be secretly installed in a room in the Palazzo Pamphili that the Pope had to pass. When the meal was finished, seeing such a noble creation, he stopped almost in ecstasy. Being prince of the keenest judgment and the loftiest ideas, after admiring it, said: "This is a trick … It will be necessary to employ Bernini in spite of those who do not wish it, for he who desires not to use Bernini’s designs, must take care not to see them."

Public fountains in Rome served multiple purposes: first, they were highly needed sources of water for neighbors in the centuries prior to home plumbing. Second, they were monuments to the papal patrons. Earlier Bernini fountains had been the Fountain of the Triton in Piazza Barberini, the Fountain of the Moor in the southern end of Piazza Navona erected during the Barberini papacy, and the Neptune and Triton for Villa Peretti Montalto, whose statuary now resides at Victoria and Albert Museum in London.

Each has animals and plants that further carry forth the identification, and each carries a certain number of allegories and metaphors with it. The Ganges carries a long oar, representing the river's navigability. The Nile's head is draped with a loose piece of cloth, meaning that no one at that time knew exactly where the Nile's source was. The Danube touches the Papal coat of arms, since it is the large river closest to Rome. And the Río de la Plata is sitting on a pile of coins, a symbol of the riches America could offer to Europe (the word plata means "silver" in Spanish). Also, the Río de la Plata looks scared by a snake, showing rich men's fear that their money could be stolen. Each is a river god, semi-prostrate, in awe of the central tower, epitomized by the slender Egyptian obelisk (built for the Roman Serapeum in AD 81), symbolizing by Papal power surmounted by the Pamphili symbol (dove). In addition, the fountain is a theater in the round, a spectacle of action, that can be strolled around. Water flows and splashes from a jagged and pierced mountainous disorder of travertine marble. A legend, common with tour-guides, is that Bernini positioned the cowering Rio de la Plata River as if the sculpture was fearing the facade of the church of Sant'Agnese by his rival Borromini could crumble against him; in fact, the fountain was completed several years before Borromini began work on the church!

The dynamic fusion of architecture and sculpture made this fountain revolutionary when compared to prior Roman projects, such as the stilted designs Acqua Felice and Paola by Domenico Fontana in Piazza San Bernardo (1585–87) or the customary embellished geometric floral-shaped basin below a jet of water such as the Fontanina in Piazza Campitelli (1589) by Giacomo della Porta.
