Mascula

Auxiliary FortNumidia · Khenchela, Algeria

About

Mascula rose on the northern slope of the Aurès at 1,200 meters, guarding the route into the mountains where Numidia met the pre-desert. Trajan's army built the post, and a cohort of Lusitanian auxiliaries held its walls alongside detachments of Legio III Augusta. The fort controlled the most important pass giving Roman Numidia access to the far side of the range. Mascula grew into a full colonia only later in the second century, well after this map's snapshot.

What happened here

Five hundred men, sometimes a thousand, recruited from a province rather than from citizens, and often stationed a long way from where they were raised. Cavalry units get a bigger fort and far more stabling; the smell tells you which kind you are in before the plan does. The layout copies a legionary fortress at a quarter of the size — headquarters, commander's house, granaries, barracks, a bath house usually built outside the walls because of the fire risk. Duties are patrolling, escorting, customs, and policing rather than pitched battle. After twenty-five years a man is discharged with citizenship for himself and his children, recorded on a bronze diploma he keeps for life. A village grows outside the gate within a decade.
