Book XI, title 42.

in the Theodosian and Justinian Codes The Codex Theodosianus and Codex Justinianus were the foundational bodies of Roman law compiled in the 5th and 6th centuries..

§. 22. The Roman Popes also constructed various and splendid aqueducts, of which it shall suffice to mention a few: Nicholas V restored the Water of the Virgin original: Aqua Virgo. This aqueduct still feeds the Trevi Fountain today., so named after a young maiden who showed certain springs to the soldiers, after it had collapsed from old age, in the year 1453.

§. 23. Sixtus V brought the Felice Water original: Aqua Felix. Named after the Pope’s birth name, Felice Peretti. to the Quirinal Hill—today called Horse Mountain original: Monte di cavallo; named for the two giant ancient statues of "Horse Tamers" (the Dioscuri) located there.—at great expense, so that the previously deserted areas of the city might be inhabited again. This is evident from the inscriptions which Domenico Fontana A celebrated Swiss-Italian architect known for moving the Vatican obelisk. recorded in his description of the transport of the Vatican Obelisk.

The first inscription, located on a certain arch outside the city, is as follows:

SIXTUS V, SUPREME PONTIFF,

HAVING RESTORED THE BRIDGES

SO THAT THE DESERTED HILLS OF THE CITY MIGHT BE INHABITED AGAIN,

ORDERED THAT WATERS BE FOUND FROM EVERYWHERE.

IN THE YEAR 1585, THE 1ST OF HIS PONTIFICATE.

§. 24. On the side of the same arch facing the City, this inscription stands:

SIXTUS V, SUPREME PONTIFF,

HAVING FINALLY FOUND SEVERAL SPRINGS OF WATER,

COLLECTED THEM INTO ONE PLACE,

AND THROUGH AN UNDERGROUND CONDUIT,

SAW THAT THEY PASSED THROUGH THIS ARCH

WHICH HE HAD FOUNDED.

IN THE YEAR 1585, THE 1ST OF HIS PONTIFICATE.

§. 25. On an arch of the same aqueduct within the city, the following inscription is read:

SIXTUS V, SUPREME PONTIFF,

CONSTRUCTED THE CONDUIT OF THE FELICE WATER

VIA AN UNDERGROUND CHANNEL FOR 13 MILES,

AND UPON ARCHED STRUCTURES FOR 7 MILES,

AT HIS OWN EXPENSE.

IN THE YEAR 1585, THE 1ST OF HIS PONTIFICATE.
