At the intersection of Via del Quirinale and Via delle Quattro Fontane are four elaborate fountains. Each was installed at a different street corner in 1593. Two of the personifications represent the River Tiber and the River Aniene. The other two sculptures portray goddesses: Diana and Juno pictured here. Juno was the wife of Jupiter, the mother of Mars and the queen of the Roman gods. The benefactor for Quattro Fontane was Pope Sixtus V.
