Happy Water or Acqua Felice....That’s what Pope Sixtus V called the Aqueduct that he commanded to be opened in 1585. Now why didn’t John Jervis think of a pretty name like that? Acqua Felice was an aqueduct that brought water to the area north of Rome, It was Pope Sixtus’ big achievement. I learned this at an exhibition in Ottawa Canada on the artistic achievements of the popes of the 16th C . I learned a lot about the various popes’ less pure activities, too. Mavis Cain.
