Juno by Domenico Fontana, Quattro Fontane in Rome, July 2012

The Quattro Fontane (the Four Fountains) is an ensemble of four Late Renaissance fountains located at the intersection of Via delle Quattro Fontane and Via del Quirinale in Rome. They were commissioned by Pope Sixtus V and built at the direction of Muzio Mattei, and were installed between 1588 and 1593. The figure of one fountain is said to represent the River Tiber, in front of an oak-tree; a she-wolf, the symbol of Rome, was a later addition. A second fountain represents the River Aniene, a tributary of the Tiber, called Anio in ancient Rome, which provided most Roman aqueducts with water. Pope Sixtus proposed to build a canal to bring the water of the Aniene to Rome. The other two fountains feature female figures believed to represent the Goddess Diana; the symbol of Chastity; and the Goddess Juno, the symbol of Strength, but it is possible that they may also represent rivers. The fountains of the Aniene, Tiber, and Juno are the work of Domenico Fontana. The fountain of Diana was designed by the painter and architect Pietro da Cortona.
