Tacitus in his _Annals_[1] merely tells us that Italy was guarded on both sides by fleets at Misenum and Ravenna, and in his _Histories_[2] speaks of these places as the well known naval stations without stopping to describe them. While Suetonius,[3] though he mentions the great achievement of Augustus, does not emphasise it and does not attempt to tell us what these ports were like. [Footnote 1: Tacitus, Ann. iv. 5.] [Footnote 2: Tacitus, Hist. ii. 100; iii. 6, 40.] [Footnote 3: Suetonius, _Augustus_.] Perhaps the best description we have of Augustan Ravenna comes to us from a writer who certainly never saw the port in its great Roman days, but who probably followed a well established tradition in his description of it. This is Jornandes, who was born about A.D. 500 and was first a notary at the Ostrogothic court and later became a monk and finally bishop of Crotona. In his _De Getarum Origins et Rebus Gestis_ he thus describes Ravenna: "This city (says he) between the marshes, the sea, and the Po is only accessible on one side. Situated beside the Ionian Sea it is surrounded and almost submerged by lagoons. On the east is the sea, on the west it is defended by marshes across which there remains a narrow passage, a kind of gate. The city is encircled on the north by a branch of the Po, called the Fossa Asconis, and on the south by the Po itself, which is called the Eridanus, and which is there known as the King of Rivers. Augustus deepened its bed and made it larger; it flowed quite through the city, and its mouth formed an excellent port where once, as Dion reports [this passage of Dion Cassius is lost], a fleet of 250 ships could be stationed in all security.... The city has three names with which she glorifies herself and she is divided into three parts to which they correspond; the first is Ravenna, the last Classis, that in the midst is Caesarea between Ravenna and the sea. Built on a sandy soil this quarter is easily approached and is commodiously situated for trade and transport."
