"It is less known, however, that P. Amiet in his study of the first form of hieroglyphics in Mesopotamia discovered that the earliest pre-cuneiform sign for 'ship' was identical with the one representing 'marine' in ancient Egypt. As shown earlier by A. Falkenstein, this hieroglyphic sign for 'ship' is very common in the earliest Sumerian texts of Mesopotamia, dating back to about 3000 B.C. It actually represents a sickle-shaped reed boat with crosswise lashings and with some peculiar S-shaped adornments both at bow and stern. This goes to show that before the two respective continental civilizations took root in Mesopotamia and Egypt about 3000 B.C. these two areas on each side of the Arabian peninsula had already a most peculiar hieroglyphic sign in common, with the same basic meaning and with ornamental details so special that they are never repeated elsewhere in the world. The bow or stern section of the same type of ship is used as a separate hieroglyphic sign. Falkenstein shows that in this earliest Mesopotamian script the Sumerian sign for 'lord' or 'gentleman' (en) is represented by the mere stem of such a reed ship, presumably the usual place for its master."
