It is the omnipresent rush of water which give the Este Gardens their peculiar character. From the Anio, drawn up the hillside at incalculable cost and labour, a thousand rills gush downward, terrace by terrace, channeling the stone rails of the balusters, leaping from step to step, dripping into mossy conches, flashing in spray from the horns of sea-gods and the jaws of mythical monsters, or forcing themselves in irrepressible overflow down the ivy-matted banks.
