There remains still a frontier territory to be looked at, which is not often mentioned, and which yet well deserves consideration; it is the Roman province of Arabia. It bears its name wrongly; the emperor who erected it, Trajan, was a man of big deeds but still bigger words. The Arabian peninsula, which separates the region of the Euphrates from the valley of the Nile, lacking in rain, without rivers, on all sides surrounded by a rocky coast poor in harbours, was little fitted for agriculture or for commerce, and in old times by far the greater part of it remained the undisputed heritage of the unsettled inhabitants of the desert. In particular the Romans, who understood how to restrict their possession in Asia as in Egypt better than any other of the changing powers in the ascendant, never even attempted to subdue the Arabian peninsula. Their few enterprises against its south-eastern portion, the most rich in products, and from its relation to India the most important also for commerce, will be set forth when we discuss the business-relations of Egypt. Roman Arabia, even as a Roman client-state and especially as a Roman province, embraced only a moderate portion of the north of the peninsula, but, in addition, the land to the south and east of Palestine between this and the great desert till beyond Bostra. At the same time with this let us take into account the country belonging to Syria between Bostra and Damascus, which is now usually named after the Haurân mountains, according to its old designation Trachonitis and Batanaea.
[Sidenote: Conditions of culture in eastern Syria.]
These extensive regions were only to be gained for civilisation under special conditions. The steppe-country proper (Hamâd) to the eastward from the region with which we are now occupied as far as the Euphrates, was never taken possession of by the Romans, and was incapable of cultivation; only the roving tribes of the desert, such as at the present day the Haneze, traverse it, to pasture their horses and camels in winter along the Euphrates, in summer on the mountains south of Bostra, and often to change the pasture-ground several times in the year. The pastoral tribes settled westward of the steppe, who pursue in particular the breeding of sheep to a great extent, stand already at a higher degree of culture. But there is manifold room for agriculture also in these districts. The red earth of the Haurân, decomposed lava, yields in its primitive state much wild rye, wild barley, and wild oats, and furnishes the finest wheat. Individual deep valleys in the midst of the stone-deserts, such as the “seed-field,” the Ruhbe in the Trachonitis, are the most fertile tracts in all Syria; without ploughing, to say nothing of manuring, wheat yields on the average eighty and barley a hundredfold, and twenty-six stalks from one grain of wheat are not uncommon. Nevertheless no fixed dwelling-place was formed here, because in the summer months the great heat and the want of water and pasture compel the inhabitants to migrate to the mountain pastures of the Haurân. But there was not wanting opportunity even for fixed settlement. The garden-quarter around the town of Damascus, watered by the river Baradâ in its many arms, and the fertile even now populous districts which enclose it on the east, north, and south, were in ancient as in modern times the pearl of Syria. The plain round Bostra, particularly the so-called Nukra to the west of it, is at the present day the granary for Syria, although from the want of rain on an average every fourth harvest is lost, and the locusts often invading it from the neighbouring desert remain a scourge of the land which cannot be exterminated. Wherever the water-courses of the mountains are led into the plain, fresh life flourishes amidst them. “The fertility of this region,” says one who knows it well, “is inexhaustible; and even at the present day, where the Nomads have left neither tree nor shrub, the land, so far as the eye reaches, is like a garden.” Even on the lava-surfaces of the mountainous districts the lava-streams have left not a few places (termed Kâ’ in the Haurân), free for cultivation.
