The Sarmatians were a race of nomadic horsemen from north of the Caspian Sea that moved west, replacing the Skythians. The Rhoxolani were among the first of the Sarmatian tribes to contact the classical world and were late in converling to armoured lancers. This list covers the early period when all but the richest were lightly armed with a short spear and bow, and were protected only by a mainly rawhide helmet, rawhide scale corslet and wicker shield and rode unprotected horses. Later armies are covered by II/26, and we assume the richest got this equipment earlier. References: Armies of the Macedonian and Punic Wars D. Head, Armies and Enemies of Imperial Rome P. Barker.
