In his rich history of Italy’s Tiber River, "Tiber: Eternal River of Rome," Bruce Ware Allen charts the main currents, mythic headwaters and hidden tributaries of one of the world’s most renowned waterways. He considers life along the river, from its twin springs high in the Apennines all the way to its mouth at Ostia and describes the people who lived along its banks and how they made the Tiber work for them. Take a trip with us backwards in time, down the banks of the Tiber.
