The conquest of all Syria as far as Euphrates and the subjection of even a part of Mesopotamia aided the diffusion of the Semitic religions in still another manner. From these regions, which were partly inhabited by fighting races, the Caesars drew recruits for the imperial army. They levied a great number of {112} legionaries, but especially auxiliary troops, who were transferred to the frontiers. Troopers and foot-soldiers from those provinces furnished important contingents to the garrisons of Europe and Africa. For instance, a cohort of one thousand archers from Emesa was established in Pannonia, another of archers from Damascus in upper Germany; Mauretania received irregulars from Palmyra, and bodies of troops levied in Ituraea, on the outskirts of the Arabian desert, were encamped in Dacia, Germany, Egypt and Cappadocia at the same time. Commagene alone furnished no less than six cohorts of five hundred men each that were sent to the Danube and into Numidia.[20] The number of inscriptions consecrated by soldiers proves both the ardor of their faith and the diversity of their beliefs. Like the sailors of to-day who are transferred to strange climes and exposed to incessant danger, they were constantly inclined to invoke the protection of heaven, and remained attached to the gods who seemed to remind them in their exile of the distant home country. Therefore it is not surprising that the Syrians who served in the army should have practised the religion of their Baals in the neighborhood of their camps. In the north of England, near the wall of Hadrian, an inscription in verse in honor of the goddess of Hierapolis has been found; its author was a prefect, probably of a cohort of Hamites stationed at this distant post.[21]
