The eastern Mediterranean seaboard - the Levant - goes 400 miles north to south from the Taurus Mountains to the Sinai desert, and 70 to 100 miles east to west between the sea and the Arabian desert. The coastal area of the southern Levant, large in the south and becoming short to the north, the southernmost part has a zone of foothills, the Shephalah; like the plain this area narrows as it goes northwards, ending at Mount Carmel. East of the plain and the Shephalah is a mountainous ridge, the "hill country of Judah" in the south, the "hill country of Ephraim" north of that, then Galilee and the Lebanon mountains. To the east again lie the steep-sided valley occupied by the Jordan River, the Dead Sea, and the wadi of the Arabah, which continues down to the eastern arm of the Red Sea. Beyond the plateau is the Syrian Desert, separating the Levant from Mesopotamia. To the southwest is Egypt, to the northeast Mesopotamia. "The Levant thus constitutes a narrow corridor whose geographical setting made it a constant area of contention between more powerful entities".
