The real meaning of the name “Arab” seems to be “desert.” It is first met with, or so it seems, in varying forms in Assyrian inscriptions of the ninth century.[1] In the Old Testament it cannot be identified with certainty before the time of Jeremiah.[2] In the inscriptions of King Darius Hystaspes, Arabaya appears to mean the Mesopotamian, Syrian, and Sinaitic desert. Amongst the Greeks we meet with the terms “Arab, Arabia” first in Æschylus (_Persians_ 316; _Prom._ 422), but the poet’s ideas of the situation of the country are altogether mythical. Herodotus, on the contrary, is fully conversant with it; he is specially interested in that district, populated by Arabs, that constitutes the connection between Palestine and Egypt which was of such importance to the Persian kingdom, and not to it alone. His contemporary, Nehemiah, is quite familiar with the name of “Arab” (Ch. 2, 19; 4, 7; 6, 16) and so is Xenophon. The latter uses the name “Arabia” of the Mesopotamian desert in particular (_Anab._ 1, 5, 1); and this very region is called “Arab” pure and simple by the later Syrians. The name has survived from that day to this, especially amongst the people themselves. It has long stood for both the nationality and the language. It is true that even in times tolerably remote Arab was understood to mean more particularly Bedouin; as is the case even in Sabæan inscriptions. The latter are, however, more exactly distinguished from the settled inhabitants of the country by the use of the plural, in its old form _A’rab_, later more frequently _Orban_.
