Niccolo Salvi designed the grand front, but the work was completed under Clement XIII., who decorated it with statues, basso relievos in marble, and different columns of the Corinthian, Ionic, and Composite orders. In the centre is a statue representing Oceanus, standing in a car, drawn by two large sea-horses, guided by Tritons. One of the horses appears furious and impatient, whilst, on the contrary, the other is

exhibited as calm and placid, so that both are symbolical of the tempestuous or tranquil state of the sea.

' Bounding to light, as if from ocean's cave, The struggling sea-horse paws the lucid wave, While health and plenty smile, and Neptune's form Majestic sways the trident of the storm.'

"A statue, designating Abundance, is placed at the right of Oceanus, and on the left another emblematical of Health. The basso relievo, which adorns the right side, portrays the Emperor Trajan, contemplating a plan of the fountain and ;

that on the left exhibits a girl showing to some soldiers, the

spring that supplies it with water. Various other sculptures decorate this superb edifice ; and at the top of the principal

front are two figures of Fame, supporting the arms of the Pope. Its supply of water is furnished by the Aqua Virgini, and it flows in very large streams from three arcades. The cost of constructing this splendid and useful fountain was great but it ranks among the most interesting objects ;

conspicuously embellishing the city of Rome."

" The Piazza Novana has a very noble fountain standing in its centre. It is composed of a large circular marble basin 79 feet in diameter, in the middle of which is placed a rock of square form with apertures at the sides. The figure of a lion adorns one side, and that of a sea-horse another.
