The larger vessels depicted with oars have in some cases as many as twenty-five shown on one side. In others the number is less. But it is quite possible that the artist did not care to portray more than would be sufficient to indicate conventionally the size of the vessel. In some of the vessels there are apertures like oar-ports, though no oars are shown in them, which raise a presumption that the invention of the bireme, the origin of which is uncertain, may with some probability be attributed to the Egyptians. The larger vessels are all fitted with sailing gear, and the rowing is evidently subsidiary to the sail as a means of locomotion. The wall paintings of Egypt give us ample details of Egyptian ships and boats extending over a period, as we are told, of twenty centuries and more. In them we have a glimpse of the maritime enterprise, in which the oar must have taken a principal part, of the races which inhabited the seaboard of the Mediterranean in which piracy had its home from very early times. Teucrians, Dardanians, Pelesta (? Pelasgians), Daunians, Tyrrhenians, Oscans, all seem to have been sea-going peoples, and at intervals to have provoked by their marauding the wrath of Pharaoh and to have felt his avenging hand. But of all the seafaring races that made their homes and highways upon the waters of the great inland sea, the most famous of early times were the Ph[oe]nicians. According to some accounts connected with Capthor (Copts), and according to others emigrants from the coast of the Persian Gulf, their genius for maritime enterprise asserted itself very early, so that already before Homer's time they were masters of the commerce of the Mediterranean, and had rowed their dark keels beyond the mystic pillars that guarded the opening of the ocean stream. And yet, though the facts are certain, we know but little of these famous mariners, of their vessels and their gear. The only representation of their vessels is from the walls of the palaces of their Assyrian conquerors, an inland people, not likely to detect or appreciate any technical want of fidelity in the likeness presented. And, accordingly, the pictures are conventional, telling us but little of that which we should like to know about their build, and oars, and oar ports, &c. The date, moreover, is not in all probability earlier than 900 B.C. Such being the case, we are driven for information to the more ample store of Greek literature, and to Greek vases for the earliest representations of the Greek vessel.
