"[...] the entire wall of a palace has been turned into a baroque fantasy of gods and goddesses, tritons and dashing steeds, set among wild rocks, wind-blown trees and a leaping, glistening, rushing cascade of water. One's first reaction is that it is so strange to find so vast a decorative fountain designed for so small a space, filling practically all of the little square. On further reflection, however, one realises that it is precisely to this apparent disproportion that it owes so much of its effect. Our surprise at finding this fantastic waterscape tucked away among small back streets adds greatly to our pleasure; although the fountain is world-famous, we enjoy the sensation of sudden revelation. This is the secret of its charm and that of much of old baroque Rome [...]." (Georgina Masson: The Companion Guide to Rome, Woodbridge 2009).
