Although Palmyra is mentioned in several cuneiform texts, the oldest of which go back to the time of Sargon I of Assyria, it seems to have remained a mere village until the middle of the first century B.C. Its sudden growth to the size of one of the largest towns in the East coincides with the moment in history when the demand for oriental luxuries began to grow in Rome and its dominions, and it was due to the clever policy of its merchants and camel-riders who knew how to keep order in the desert between their town and the great factories and warehouses of Lower Mesopotamia. From that time caravans were able to cross the Syrian desert instead of skirting it, and the transit brought huge profits to the Palmyrenes. The desert therefore, whose barren waste, to our European eyes, would easily seem a barrier, was no such thing in reality, but acted on the contrary as a link with Mesopotamia, very much in the same way as the sea connected Venice by her merchant ships with the harbours of the Levant. Indeed, a comparison of Palmyra with the great commercial cities of the Middle Ages and the Renaissance (Venice, Antwerp, Bruges, Lisbon, etc.), is one that in several respects helps us to understand its sudden and great prosperity, as well as its sudden decline. From the day when Aurelian put an end to Palmyra's command of the wilderness, the roads of commerce had to change, the caravans again resorted to the Euphrates route around the desert, and the fortunes of Aleppo and Chalcis began to rise.
