The limitanei or ripenses, meaning respectively "the soldiers in frontier districts" (from the Latin phrase limes, meaning a military district of a frontier province) or "the soldiers on the riverbank" (from the Rhine and Danube), were an important part of the late Roman and early Byzantine army after the reorganizations of the late 3rd and early 4th centuries. The limitanei, unlike the comitatenses, palatini, and scolae, garrisoned fortifications along the borders of the Roman Empire and were not normally expected to fight far from their fortifications.
