Abstract

Recent studies have shown that Nicola Salvi the architect of the Trevi Fountain intended to present the “potenza non limitata” of water as an existential element of nature, focusing the whole appearance of the fountain on the person in the center, Oceanus. But Salvi’s principal, pope Clement XII., claimed in his other projects such as the restoration of the arch of Constantine or like the new eastern fascade of S. Giovanni in Laterano, which refer especially to Constantine, like this emperor the leader of Christianity. Thus Salvi’s philosophical purpose seems not to be in line with to the intentions of the pope. But how could Salvi convince the pope let him build the prestigious fountain? This paper tries to show that Salvi’s model was influenced by the epiphanies of Neptun or Poseidon in the first book of the Achilleis of Statius and in the 13th book of the Iliad. Transferring these on the epiphany of Oceanus in the Trevi Fountain, Salvi was able to combine his thoughts about the power of water with the metaphorical presentation of a universal ruler, as the pope wanted to present himself.
