Timgad was built by the soldiers of the Third Legion, then stationed at Tebessa. Its head-quarters were shortly afterwards moved to Lambessa, and during the second and third centuries the frontier outposts were gradually pushed forward. They occupied a line on the south side of the Aurès range, extending to the south and south-east of Biskra and then branching north-west to Bou-Saida. At least in some districts a ditch and rampart marked the limits of the Empire. Lambessa grew into a large city said to have contained 60,000 inhabitants. Its considerable ruins, of which the most important are the Prætorium and certain arches, are visible to-day. The importance of the position is realized by the French, who have large barracks and a force of 4000 men at Batna, only a few miles off. Striking evidence of the success of Rome’s treatment of subject races is to be found in the fact that with all the wealth of numerous great cities to protect, her military force in North Africa consisted only of one legion of 5500 men and auxiliary forces of infantry and cavalry, making a total of 15,000 men. At first the legionaries were raised in Europe, chiefly in Gaul, but in the second century they were recruited entirely among the indigenous population. Retired soldiers were granted lands and exemptions on the condition that their sons enlisted. In this way towns like Lambessa, half military, half commercial, grew up. The actual number of emigrants from Italy was small; with her declining population she had no emigrants to send. There is, therefore, reason to believe that the inhabitants of such cities as Timgad were not to any appreciable extent colonists from Europe; they were rather Romanized Berbers. The names as they appear in inscriptions corroborate this. They are not Latin, if Latin in form. This point is of great importance in considering not only the nature of the Roman rule in North Africa, but also the history and possibilities of the Berber population. They were Romanized once, they are Arabized to-day; what may they be to-morrow? As we stand in the Forum of Timgad to-day, we may reflect that this noble city was built and inhabited by the ancestors of the gabbling native crowd which is holding its market at the gate. Doubtless in their simple minds these robed figures are wondering what in the world we come for. They must be aware that it is not a religious exercise; we have our holy places to which they observe that some of us betake ourselves on Sunday mornings; no Christian marabout lies buried here, and we are therefore not votaries making a pilgrimage. Yet is our conduct not mere levity; we wander about with little books in our hands and are very earnest and sometimes vociferous to our companions. Perhaps the most enlightened native opinion inclines to the belief that we are working a spell or enchantment, it may be for the benefit of our motor-cars, which we bring with us to the gate.
