Centurion

The Roman Centurion (; , . ; , or ) was a professional officer in the Roman army, commanding a group of soldiers called a centuria.
The term centurion is derived from the Latin word centurio, which itself originates from centum, meaning "hundred." Initially, centurions were commanders of a unit of roughly 100 soldiers, although the exact number varied over time and by period. The concept of the centurion emerged during the early Roman Republic (509–27 BCE), when Rome's military was based on citizen-soldiers organized into centuries (centuriae), units of 100 men within the Roman legio (legion).

Role

In the Roman infantry, the centurions commanded a ''centuria'' or "century". During the Mid-Republic these centuries were grouped in pairs to make up a maniple, each century consisting of 30–60 men. After the so-called "Marian reforms", a century was typically composed of around 80 men, with six such centuries forming a cohort.

Centurions were drawn from five main sources within Roman society and the military. Some were promoted from the ranks of ordinary soldiers, often after holding minor posts under the centurionate. Others, though less commonly, gained their promotion after serving in auxiliary units. The remaining three sources were the most common. One group consisted of individuals from a class whose property qualifications were below that of the equestrian order. These men received their positions in the legions as a reward for merit. Many of them were magistrates from municipal towns who, through their service, secured full Roman citizenship, making them eligible for legionary service and subsequent appointment as centurions in recognition of their prior careers.

A notable fourth category of centurions came from the equestrian order. These individuals (ordinem accepit ex equite Romano) had previously held equestrian status but either lost their wealth, failed to advance in the equestrian career (cursus honorum), or chose to resign from the order. They voluntarily accepted a centurion’s commission in the legions, often seeking a different path to distinction within the Roman military structure.

Seniority

The centurions of a legion were all subject to a grading system that determined their rank. The centurions of the triarii maniples occupied the most senior position, followed by those of the principes, who in turn were senior to the centurions of the maniples of the hastati. Within each of the three lines, seniority levels increased as individuals progressed from left to right. A further distinction existed between prior and posterior centurions within the maniple, such that the posterior centurion of the maniple of the hastati, positioned at the far left of the line, was the most junior centurion in the legion, while the prior centurion of the maniple of the triarii, situated at the far right of the line, was the most senior. The centurion in question was known as the primipilus, since from the second century the triarii were often referred to as the pilani because of their column-like formation.

Centurions were ranked hierarchically within the legion, with each legion containing 60 centurions, each commanding a centuria. The ranks of centurions reflected their seniority and responsibilities:

Primus Pilus (First Spear):
The highest-ranking centurion of the legion, commanding the first centuria of the first cohort. The primus pilus often served as an advisor to the legate (legion commander) and had significant influence over the legion's operations.

Pilus Prior:
The centurion of the first centuria in a cohort, ranked just below the primus pilus. Each cohort had a pilus prior.

Princeps Prior and Hastatus Prior:
Commanders of the second and third centuriae in a cohort, respectively. These centurions were of intermediate rank within the legion hierarchy.

Other Junior Centurions:
Centurions commanding lower-ranked centuriae had titles reflecting their position in the cohort, such as hastatus posterior or princeps posterior.

Qualities

A centurion was required to meet strict physical, tactical, and leadership standards, embodying the ideals of a Roman officer. They were chosen for their exceptional size, strength, and dexterity, particularly in throwing missile weapons and demonstrating expertise in the use of the sword and shield. Proficiency in all military exercises was essential to their role. Beyond physical capability, a centurion needed to possess key personal traits such as vigilance, temperance, and energy, ensuring they were always alert, self-controlled, and active in fulfilling their duties.

Obedience and discipline were paramount, as a centurion was expected to execute orders promptly and efficiently, prioritizing action over unnecessary discussion. They were also responsible for maintaining strict discipline among their soldiers, ensuring that their troops were clean, well-dressed, and presented a professional appearance at all times. Additionally, they oversaw the upkeep of weapons, requiring them to be polished, rubbed, and kept in excellent condition. In essence, the centurion was the embodiment of Roman military ideals, combining physical prowess, discipline, and leadership while enforcing these high standards among their men.

Uniform and Equipment

Centurions, as pivotal leaders in the Roman military, directly commanding men and participating alongside them in combat, were equipped similarly to their soldiers during the early periods of Roman history, but with distinct features that set them apart. In the early Republic, a soldier's equipment included a bronze or iron helmet (''galea''), chain-mail (''lorica hamata'' — punched rings attached to each other with riveted or welded rings, forming a flexible metal "fabric" shaped into a vest or shirt, with additional material folded over the shoulders and secured across the chest with ties or metal clasps), scale armor (''lorica squamata'' — metal scales wired together or sewn to a fabric backing, or ''lorica plumata'' — smaller scales attached to fine chain-mail, giving a "feathered" appearance), and the standard oblong shield (''scutum''). They carried the short stabbing sword (''gladius''), essential for close combat, a decorated dagger (''pugio''), and a spear (''hasta'') for thrusting attacks. One of the distinguishing features of a centurion’s rank was the crest on their helmet, earlier mounted longitudinally, running front to back, resembling a boar’s crest, though its orientation evolved in later periods, with centurions wearing transverse (side-to-side) crests, while the ''optio'' adopted the longitudinal crest. This made centurions more visible to their men during battle, giving them a visual mark to maintain formation, allowing their officers to more effectively lead and coordinate their troops. As individual soldiers purchased their own equipment out of an allowance, the particular form of a centurion's equipment could vary between units, across different territories, and over time, reflecting prevailing fashions and personal preferences.

Late Republic and Early Empire

During the Late Republic and the Early Empire, centurions began to wear more ornate and elaborate armor as a symbol of their elevated status. Their equipment was not only practical but also designed to command respect and authority on and off the battlefield. Key features of this period included:

Crested Helmet: Centurions wore helmets with a transverse crest made of horsehair or feathers, running left to right. This distinct design made them easily identifiable amidst the chaos of battle, serving both as a rallying point for soldiers and a mark of leadership.

* Segmented Armor: Centurions increasingly adopted ''lorica segmentata'' (an ahistorical term used by modern researchers, as the original name for this armor has been lost; Latin writers typically referred to any kind of body armor as ''lorica''), a type of segmented plate armor that provided excellent flexibility and protection, possibly based on armor worn by a class of gladiator after a Gallic fashion known as '' crupellarius''. While this armor became popular, chain-mail (''lorica hamata'') remained widely used, particularly among centurions in less affluent units or those stationed in less resourced provinces, however ''lorica hamata'' was more flexible than segmented armor, offered more protection to the upper thigh, more comfortable in hot climates, and could be repaired more easily, as it consists of only two types of uniformly sized rings, while segmented armor consists of multiple plates of different shapes requiring various forming operations to manufacture, connected by rivets to leather straps, and closed with tie loops, buckles, and clasps made of copper alloy.

* Muscled Armor: Armor consisting of a separate breastplate and backplate of metal, typically bronze, though some examples in iron are known to exist, with the breastplate shaped to resemble a heavily muscled human torso, as often seen in ancient artworks, typically associated with divine and heroic figures. Although often depicted in artwork as extending in a curved arch from the hips downward to protect the belly, in practice this would prevent bending at the waist; archaeological finds of actual armor meant for use in battle , as opposed to pieces made specifically as offerings for temple dedications, feature breastplates terminated at the waist, sometimes with a forward-projecting flare to accommodate riding on horseback. Some examples are highly detailed, with embossed, chased, and carved imagery representing mythological themes, members of the imperial family, historical events, classical designs such as acanthus leaves, or abstract figures.

* Vine staff: (''vitis''): The ''vitis'' was a short staff, traditionally made from a section of grapevine, carried by centurions as a symbol of their authority within the legion, similar to the "swagger stick," but also used to enforce discipline among the ranks, used by centurions at the rear of a file to urge on soldiers in front, and to beat any attempting to flee. The ''vitis'' was also used to flog soldiers as punishment.
* Ornamentation: Centurions’ armor and equipment were often adorned with intricate designs and embossed decorations, featuring motifs such as gods, animals, or other symbols of Roman power. These embellishments further highlighted their rank and distinguished them from ordinary soldiers. Many of these would have been awards for bravery and distinguished service, such as the laurel crown for leading troops to victory, and the mural crown, for being the first over an enemy's city wall. Multiple awards and medals could be displayed on a harness of leather straps worn over the armor; likely these were only worn for formal dress or parade occasions, and removed before battle.

By the High Empire, centurions’ uniforms and equipment became even more elaborate and ceremonial, reflecting the increasing professionalization and hierarchical structure of the Roman military. Their distinctive appearance emphasized their authority and their role as elite officers within the legions. Key features of this period included:

* '' Cingulum militare'': A highly decorated military belt worn over the ''tunica'', often featuring intricate metalwork and symbolic decorations. The ''cingulum'' was a practical item for carrying weapons but also served as a status symbol; soldiers in civilian garb would wear their ''cingulae'' over the everyday tunic as a mark of service.
* Cloak (''Sagum''): Centurions commonly wore a red cloak, known as the ''sagum'', which symbolized their rank and authority. The red color was associated with power and leadership and made them stand out visually among the ranks.
* Greaves: Centurions often wore metal leg guards, or greaves, to protect their shins during combat. These were typically worn on one or both legs and reinforced their distinctive and prestigious appearance. Compared to greaves of the Classical Greek hoplite, made of a single piece of bronze shaped to the individual, secured by its own spring tension, Roman greaves typically only covered the front of the shin, with a separate protection for the knee (''patella'') connected with a hinge, and was secured to the leg with straps or ties.

Late Empire (3rd–5th Century CE)

As the Roman army adapted to new threats and incorporated diverse influences, centurions’ uniforms became less standardized. The use of chain-mail and scale armor increased, as these could be more easily mass-produced and later adjusted to fit the wearer, while the iconic ''lorica segmentata'', individually fitted to a particular wearer, fell out of favor. Helmets became more conical, influenced by Eastern and Germanic designs, abandoning hammered or spun bowl designs, in favor of helmets consisting of two pieces riveted together along the top from front to back, forming a reinforced ridge, sometimes extending into a nasal. These helmets, called Spangenhelm, often associated with Germanic and Scandinavian warriors, reflected their recruitment to serve in Late Roman and Byzantine imperial armies.

In the New Testament

Matthew's Gospel and Luke's Gospel relate an incident in which a servant of a centurion based in Capernaum was ill. In the Gospel of Luke, the centurion concerned had a good relationship with the elders of the local Jewish population and had funded the development of the synagogue in Capernaum, and when he heard that Jesus was in the locality, he asked the Jewish elders to request healing for his servant. In the Gospel of Matthew, the centurion makes direct contact with Jesus. The stories report that Jesus marveled at his faith and restored his servant to health.

In both the Gospels of Mark and Matthew, the centurion who is present at the Crucifixion said that Jesus was "God's Son". Accordingly, this centurion is considered by many to be the first Christian. In Luke's Gospel, the centurion at the cross said that Jesus was "innocent".

The Book of Acts tells of a centurion named Cornelius whose righteous and generous acts find favor with God. The apostle Simon Peter is told in a vision to visit Cornelius, a Gentile, with whom association was not permitted under Jewish law. The encounter leads Simon Peter to understand that God accepts non-Jews who believe in God and repent. After this revelation, the message of Jesus was evangelized to the Gentiles. Another centurion, Julius, is given custody of the apostle Paul for his journey from Caesarea to Rome in Acts 27. and verses 6, 11, 31, and 43
