Before the close of the second century A.D. there were afloat not only the Italian fleets, but also those of the Roman provinces. There was the Egyptian fleet based on Alexandria, the Syrian fleet, the Libyan fleet, the Euxine fleet, besides two fleets on the Danube and the Rhine. Furthermore, there must not be omitted the Romano-British fleet—the Classis Britannica—which was based on Boulogne (Gesoriacum), with stations at Dover, Lympne, and Gloucester. This dated from the invasion by Claudius and assisted Agricola in his Scottish expedition in A.D. 83. It circumnavigated Britain, discovered for the Romans the Orkneys, and saw the long line of the outer Hebrides. The classiarii also on shore helped to build Hadrian’s wall. But as to the exact nature of such ships we shall speak in greater detail presently.

Each of the fleets just mentioned was commanded by a præfectus and had also a sub-præfectus. The Egyptian fleet-præfect was sometimes also præfect of the Nile revenue boats. Each ship was commanded by a trierarch, the classiarii being organised as a century under a centurio-classicus, or fleet-centurion. Thus whenever the men had to be put on shore for duty their organisation went with them. The term of service for the classiarii was twenty-five or twenty-six years. The Roman fleets illustrated at an early date in the world’s history what every nation has since been compelled to realise: that a standing navy cannot be dispensed with among the essential attributes of peace and self-defence. Rome’s fleets kept off Carthage and Philip and enabled Rome to be mistress of the sea route between Hannibal and Spain; and, as is usually the case, the decadence of the Government was promptly followed by the decadence of the fleet.

(From Scheffer’s “De Militia Navali.”)

The influence of the Roman navy on land was seen in a manner similar to that in which the Roman army influenced gladiatorial combats. In Rome there were various “naumachiæ,” which were great reservoirs surrounded by seats like an amphitheatre and were specially constructed for holding naval fights. There was one, for instance,[14] built by Augustus on the trans-tiberine side of the river, and traces of this naumachia were discovered not many years ago. A naumachia consisted of an enormous tank or lake excavated in the ground, and measured 1800 feet long by 1200 feet wide. Within this ample area naval battles containing thirty beaked ships with three or four tiers of oars, together with many other smaller ships were engaged, and no fewer than three thousand fighting men, to say nothing of the rowers, were engaged. It is interesting to add that naval fights were also held in a gigantic reservoir on the site now occupied by the Colosseum.
