And so it went on until Rome realised that piracy had long since ceased to be anything else but a most serious evil that needed firm and instant suppression. It was the ruin of overseas trade and a terrible menace to her own territory. But the matter was at last taken in hand. M. Antonius, proprætor, was sent with a powerful fleet against these Cilician pirates; they were crushed thoroughly, and the importance of this may be gathered from the fact that on his return to Rome the conqueror was given an ovation. In the wars between Rome and Mithradates the Cilician pirates rendered the latter excellent service. The long continuance of these wars and the civil war between Marius and Sylla afforded the Cilicians a fine opportunity to increase both in numbers and strength. To give some idea of their power it is only necessary to state that not only did they take and rob all the Roman ships which they encountered, but they also voyaged among the islands and maritime provinces and plundered no fewer than 400 cities. They carried their depredations even to the mouth of the Tiber and actually took away from thence several vessels laden with corn. Bear in mind, too, that the Cilician piratical fleet was no scratch squadron of a few antique ships. It consisted of a thousand vessels, which were of great speed and very light. They were well manned by most able seamen, and fought by trained soldiers, and commanded by expert officers. They carried an abundance of arms, and neither men nor officers were lacking in daring and prowess. When again it became expedient that these Cilicians should be dealt with, it took no less a person than Pompey, assisted by fifteen admirals, to tackle them; but finally, after a few months, he was able to have the sea once more cleared of these rovers.
