Pavkovie Introduction The Roman military establishment of the high empire was composed of four different categories of units. The first category was the so-called militia urbana, the units station- ed in and around the city of Rome; included in this group were the members of the imperial guard. The most famous troops of the imperial household were the Praetorians who formed the infantry component of the guard? The mounted portion was furnished by the horseguards of the emperor, the equites singulares Augusti, who were drawn from the auxiliary cavalrymen on the frontier and were charged with the protection of the emperor's persom2 The second category of troops formed the mainstay of the Roman ar- my: the legions.3 These were units of Roman citizens approx- imately 5000 strong, mostly infantrymen but including a small contingent of cavalrymen, usually 120 men under the high empire, but later substantially increased up to at least 726. The legions were deployed along the frontiers and pro- A vast amount of academic ink has been spilled on vided Roman generals with the close order infantry who various topics concerning the legions such as their officers, formed the line of battle. organization, recruitment, and the histories of individual The third group of units were those of auxiliaries.*The legions.

The first century auxiliaries are most often depicted in the so-called rider-relief, where the trooper is shown mounted on his horse riding down a defeated barbarian op- ponent; the soldier is often accompanied by his servant (calo) who carries additional spears (see Figure 1). In the rider-God, also known as the Danubian Rider,9 the equipment shown on the gravestone was that of the trooper when in battle. He is represented with a helmet (usually, at least), protec- tive body-armor, usually chain mail (lorica hamata) or, less frequently, scale mail (lorica squamata), a large shield, a spear capable of being thrust or thrown (hasra), and a sword, usual- ly of the long Celtic-type (spatha). Of the six stones of the legionary horsemen which can be dated to the first century A.D., four represent the deceased in the posture of the Thracian Rider-God (Plate 1)!O Three of the stones are rather badly weathered and as a result on- ly the most obvious articles of equipment are still clearly visible: the shield, the spear, and, in one instance, the helmet." One stone, however, is fairly well-pre~erved!~The stone, from Bonn, represents a certain Caius Marius who served fifteen years in legio I Germanica (Plate 2). Marius is depicted as bare-headed, but wears some type of armor over his tunic; the armor is in turn decorated with his military decorations (dona militaria). The type of the armor cannot be determined from the stone, but was probably painted to represent chain mail?3 He also carries the characteristic spear and shield so well-known from the reliefs of the auxiliaries. The two stones not from the Thracian Rider-God genre show the same basic elements of equipment. One gravestone of two brothers, both equites legionis, from the early first century A.D., has a very small battle scene which shows a legionary horseman in combat with a mounted barbarian op- ponentJ4 The legionary horseman carries the typical cut-oval shield.

Three There are two grave reliefs of the legionary horsemen from the early third century A.D. Unlike the first century basic types of evidence can be adduced for the arms and examples, these stones portray the troopers standing about armor of these men: 1) the depictions of legionary horsemen in camp uniform rather than in full battle equipment. One on monuments including their tombstones; 2) the ar- chaeological remains of their arms and armor; and 3) the of our stones thus shows the deceased only with a spear and shield while the other shows the trooper merely with a occasional literary or documentary reference to the equip- ment of the legionary cavalry. sword.

This is the early first century triumphal arch at Orange in southern France (ancient Arausio). The monument was erected to celebrate the suppression of a Gallic revolt by legio IIAugusta?'
