forms the extensive port known as that of Vatrenus, where 
Claudius Caesar \ on his triumph over the Britons, entered 
the Adriatic in a vessel that deserved rather the name of a 
vast palace than a ship. This mouth, which was formerly 
called by some the Eridanian, has been by others styled the 
Spinetic mouth, from the city of Spina, a very powerful place 
which formerly stood in the vicinity, if we may form a con- 
clusion from the amount of its treasure deposited at Delphi ; 
it was founded by Diomedes. At this spot the river Vatre- 
nus^, which flows from the territory of Torum Cornell, swells 
the waters of the Padus. 
The next mouth to this is that of Caprasia^, then that 
- of Sagis, and then Volane, formerly called Olane ; all of 
which are situate upon the Flavian CanaP, which the Tus- 
cans formerly made from Sagis, thus drawing the impe- 
tuous stream of the river across into the marshes of the 
Atriani, which they call the Seven Seas ; and upon which is 
the noble port of Atria ^, a city of the Tuscans, from which 
place the sea was formerly called the Atriatic, though now 
the Adriatic. 
We next come to the overflowing mouths of Carbo- 
naria, and the Fosses of Philistina^, by some called Tarta- 
^ It was on this occasion that, after a stay of only a few days in Britain, 
he quitted the island, returned to Rome, and celebrated a splendid tri- 
umph. This outlet of the Po has now the name of Po di Primero. 
2 Now the Santerno, noted for the sluggishness of its waters. 
3 The Ostium Caprasise is now called the Porto Interito di Bell' Ochio, 
the Ostium Sagis the Porto di Magnavacca ; Tolane, or Yolana, is the 
south main branch of the river. The Ostia Carbonaria, mentioned below, 
was the north main branch, subdivided into several small branches ; and 
the Fossae or Fossiones PhiListmse connected the river, by means of the 
Tartarus, with the Athesis. 
^ The reading is doubtful here, and even this, which is perhaps the best, 
appears to be corrupt ; for it is difficult to conceive how all the mouths 
previously mentioned could have been upon one canal, and besides it 
- would seem that Olane was one of the natural mouths of the river. 
* More generally Adria, from which, as Pliny says, the Adriatic takes 
its name. Either a Grreek, or, what is more probable, as Pliny states, an 
Etruscan colony, it became the principal emporium of trade with the 
Adriatic, in consequence of which it was surrounded with canals and 
other works to facilitate its communications with other rivers. It is 
still called Adria, and in its vicinity to the south, considerable remains 
of the ancient city are still to be seen.
