=Physical Characteristics of Syria and Palestine.= In marked contrast with Arabia was the strip of hill and mountain country lying on the eastern coast of the Mediterranean, known in later tunes as Syria and Palestine. The dominant feature in this part of the Semitic world was the southern spurs of the Taurus mountains, which here run parallel with the coast in two ranges known as the Lebanons and the Anti-Lebanons. A warm, equable climate and fertile soil, especially in the broad valleys between the mountains, furnish the first necessities for a strong civilization. Frequent rain during the whiter and many perennial springs and brooks supply throughout most of this region the water needed for a prosperous, agricultural population. The desert on the east and the mountains in the north were the homes of active, migrating peoples whose ever-recurring attacks gave the inhabitants of Syria and Palestine a constant stimulus. =Its Central Position and Lack of Unity.= This region was also the isthmus lying between the sea and the desert that connected Asia with Africa, and the ancient empires of Egypt and Babylonia. The great caravan routes led across it from Arabia on the south and Babylonia on the east to Asia Minor and thence by sea to the ports of the northern Mediterranean. One fatal defect, however, prevented it from becoming the permanent home of one strong, conquering people: it lacked physical unity. Its two rivers, the Orontes and the Jordan, were comparatively unimportant and flowed in opposite directions. Mountain ranges running from north to south and in the north one running from east to west divided the territory into eight or ten distinct areas. Wide variations in climate, flora, and fauna separated these different zones, making a uniform civilization practically impossible. No region, except the fertile valley between the Lebanons and Anti-Lebanons, possessed sufficient natural advantages to rule the whole territory immediately east of the Mediterranean. As a result Syria and Palestine were only at rare and comparatively brief periods completely dominated by native conquerors. The physical characteristics of this territory also suggested from the first a mixed civilization, combining those of the desert, of Babylonia, of Egypt, and of the other lands lying along the Mediterranean. The infusion of foreign elements largely explains the remarkable culture and religious life that flourished within the narrow bounds of Syria and Palestine. This land was at the same time the strategic point that commanded the rest of the ancient world and was destined to send forth influences that were to extend to the uttermost parts of the earth.
