Four Fountains

This guide to the Four Fountains in Rome centers on Pope Sixtus the Fifth, who spent his brief five-year papacy cutting straight new boulevards through the medieval city to link its great basilicas. It follows what that project cost, from a demolished ancient monument used for building stone to a long-dry aqueduct he brought back to life to supply this hilltop crossroads. Look at the reclining figures in each niche, from the Tiber with his she-wolf to Juno resting on her lion, and see if you can spot which one still divides scholars.
