Southern Phoenicia, having once launched on the stream of Asiatic politics, followed its fluctuations, and was compelled henceforth to employ in her own defence the forces which had hitherto been utilised in promoting her colonial enterprises. But it was not due to the foolish caprice of ignorant or rash sovereigns that Tyre renounced her former neutral policy: she was constrained to do so, almost perforce, by the changes which had taken place in Europe. The progress of the Greeks, and their triumph in the waters of the AEgean and Ionian Seas, and the rapid expansion of the Etruscan navy after the end of the ninth century, had gradually restricted the Phoenician merchantmen to the coasts of the Western Mediterranean and the Atlantic: they industriously exploited the mineral wealth of Africa and Spain, and traffic with the barbarous tribes of Morocco and Lusitania, as well as the discovery and working of the British tin mines, had largely compensated for the losses occasioned by the closing of the Greek and Italian markets. Their ships, obliged now to coast along the inhospitable cliffs of Northern Africa and to face the open sea, were more strongly and scientifically built than any vessels hitherto constructed. The Egyptian undecked galleys, with stem and stern curving inwards, were discarded as a build ill adapted to resist the attacks of wind or wave. The new Phoenician galley had a long, low, narrow, well-balanced hull, the stern raised and curving inwards above the steersman, as heretofore, but the bows pointed and furnished with a sharp ram projecting from the keel, equally serviceable to cleave the waves or to stave in the side of an enemy's ship. Motive power was supplied by two banks of oars, the upper ones resting in rowlocks on the gunwale, the lower ones in rowlocks pierced in the timbers of the vessel's side. An upper deck, supported by stout posts, ran from stem to stern, above the heads of the rowers, and was reserved for the soldiers and the rest of the crew: on a light railing surrounding it were hung the circular shields of the former, forming as it were a rampart on either side.

Sennacherib affirms that vessels of this type had been constructed by Syrian shipwrights, and were manned by Tyrian, Sidonian, and Ionian sailors.
