A REAL Day in the Life of a Roman Soldier in 117 AD – What It Was REALLY Like
Hang on because what you are going to discover about life in ancient Rome will surprise you at every detail. It was still pitch black when the cornicen, the horn blower of the camp, sounded the first signal of the day in the year 117 after Christ. The Roman army was operating on several fronts at the same time, garrisoned on the borders of the Rhine and the Danube in Europe, maintaining order in the recently conquered provinces of Dacia, and supervising the territories of the Middle East that Emperor Trajan had snatched from the Parthians a few years
before. For the Roman legionary, Marcus Aurelius Verus, a fictional soldier but representative of thousands of real men who lived this reality. The day began exactly the same way every day, 7 days a week, 365 days a year. The permanent Roman camp called castra was a real city in itself, always built according to the same rectangular format with internal streets organized in a grid, external ditches, wooden or stone ramparts, and gates on each of the four sides.
The castra welcomed between 4,000 and 6,000 men when a full legion was stationed there. Marcus slept in a barracks shared with seven other soldiers, the famous contubernium, the smallest social unit of the Roman army. These eight men shared not only sleeping space, but also meals, guard duties, collective equipment, and in many cases, a loyalty that lasted for decades.
The historian Vegetius, the military treatise of Publius Flavius Vegetius at the end of the 4th century after Christ, documents with precision that the routine in Roman camps was standardized over several centuries. This means that what Marcus experienced in 117 after Christ was essentially the same thing that a legionary had experienced in the time of Julius Caesar, 150 years before.
Consistency was a weapon in itself. An army that executes the same movements every day does not [music] need to think in combat. It acts by instinct. At 4:00 in the morning, Marcus got up. No question of lingering in bed. The punishment for delays or negligence was known to all. The fustuarium, a brutal punishment where the at fault soldier was beaten by his own comrades of the contubernium.
The historian Polybius described this punishment with disturbing details. Most of the condemned died during the procedure. It was rarely pushed to this extreme, but the threat was enough to guarantee that no man slept more than reasonable. The dressing process was already in itself a technical sequence. The Roman armor, the famous lorica segmentata, with its overlapping horizontal iron bands, was not something you put on easily by yourself.
Marcus needed the help of a comrade to adjust the back bands and check that the bronze clasps were correctly locked. Under the armor, he wore a thick wool tunic that reached his knees. Wool socks wrapped around his legs and military sandals called caligae, heavy sandals with thick leather soles reinforced with iron nails that ensured grip on any terrain and withstood months of intensive marching.
The Roman helmets of the galeae or Cassis type were real feats of engineering. Made of iron or bronze, they had side protections covering the cheekbones, a wide rear rim deflecting sword blows to the neck, and a top crest which, on the officer’s versions, supported colored plumes used for identification on the battlefield.
On the helmets of ordinary soldiers like Marcus, the crest was generally transverse, from ear to ear, while on centurions, it ran from front to back, making them immediately recognizable to their men even in the middle of combat chaos. The Roman shield, the scutum, was also a remarkable engineering object. Rectangular, slightly curved to fit the soldier’s body, it measured about 80 cm wide by 1 m 20 high.
Built with layers of wood glued in alternating directions, a technique similar to what is called today plywood, and covered with animal leather painted in the colors of the legion, the scutum weighed between 5 and 6 kg. Combined with the full armor, the pilum spear and the short sword, gladius, Marcus carried between 15 and 20 kg of equipment even before putting on his marching pack.
The diet of the Roman soldier is one of the most surprising aspects of life in ancient Rome for the modern observer. Contrary to what many imagine, the diet of legionaries was not mainly composed of meat. Wheat was the absolute base of everything. Each Roman soldier received a daily ration of about 800 g to 1 kg of raw wheat.
It was the responsibility of the contubernium itself to grind this wheat in the portable mills that were part of the unit’s collective equipment. The ground wheat became flour, and the flour became bucellatum, a kind of hard and dry biscuit that could be kept for several weeks or poles, a cooked wheat porridge resembling a thick puree seasoned with salt, olive oil, and when it was available, aromatic herbs.
The archaeological records of Vindolanda, a Roman fort in present-day England dating from the 2nd century after Christ, revealed something extraordinary. The Tabulae Vindolandenses, small wooden tablets preserved by the acidic soil containing the daily correspondence of the soldiers. Among the documents found, there are food lists mentioning not only wheat and barley, but also beer, wine mixed with water, posca, the official drink of the army, olives, olive oil, cured cheese, eggs, salted fish, and from time to time, pork
or beef. The Roman military diet was within the limits of possibility at that time, reasonably balanced. Marcus that morning of the year 117 after Christ eats his wheat pulse with olive oil and a few olives preserved in salt. There is also a piece of hard cheese and a cup of posca, the mixture of wine vinegar diluted in water that the Romans used as a daily drink, and which by chance possessed antibacterial properties, helping to prevent waterborne diseases.
At a time without a modern sanitary treatment system, this detail may have saved countless Roman lives. The food was prepared on collective fires positioned outside the barracks in designated areas of the castra. Each contubernium had its own utensils, ceramic or iron pots, knives, wooden spoons, and a set of mess tins. Cooking together was much more than a matter of nutrition.
It was a ritual of social cohesion. Polybius observed that soldiers who cooked and ate together developed a sense of mutual trust that translated directly into their combat effectiveness. When the legion was on active campaign, marching or in the field, the supply of food became logistics of industrial scale.
A legion of 5,000 men consumed about 6 tons of wheat per day, the annona militaris. The Roman military supply system was managed by a network of administrative officials, regional depots and contracts with local producers who guaranteed that this volume reach the fighting units. This system was so sophisticated that modern historians consider it as one of the precursors of contemporary military logistics systems.
The training of the Roman soldier was not something that happened only at the beginning of the military career. It was a daily practice without exception during all the years of active service. It is one of the most distinctive characteristics of the Roman army compared to practically all its contemporaries.
Vegetius is explicit on the subject in his treatise. The Roman wins through work where others succumb to heat or cold. Continuous training makes the ordinary soldier an extraordinary warrior. This philosophy translated into a physical exercise regimen that began right after breakfast and occupied most of the mornings when the legion was not marching or in combat.
Basic physical training included running, typically a full lap of the camp perimeter, which in a full legion castra could reach 4 or 5 km, jumping in full equipment, swimming in nearby rivers when possible and long marches with full load. Vegetius documents that the minimum required was that every soldier be able to cover 24,000 Roman paces, about 35 km in 5 hours with full equipment.
This was not an exceptional feat. It was the ordinary pace of Roman military marches. But the heart of the training was the combat itself. Each morning, Marcus and his comrades spent hours training with practice weapons. Wooden swords weighing twice as much as real swords, woven wicker shields heavier than combat shields. This technique consisting deliberately in training with equipment heavier than the real thing is documented by Vegetius and was only rediscovered by modern sports psychology in the 20th century.
When the athlete switches to real equipment in competition, he instantly feels more agile and more precise. The training targets were wooden stakes driven into the ground called palace. Each soldier had his own assigned stake and trained against it repeatedly. Thrusting blows aiming at the throat and face.
Shield blows to unbalance the opponent. Side dodge, fast advance. The gladius Hispaniensis, the short double-edged sword that became the standard weapon of the legionary, was a weapon designed for thrusts, not for slashing blows. This required a completely different technique from the long swords used by Germanic or Celtic barbarians.
And this technique had to be so internalized that it became an automatic reflex. The throwing of the pilum was another skill worked on obsessionally. The pilum was a spear of about 2 m with a wooden shaft and a soft iron shank that bent on impact. A genius design serving two purposes simultaneously. First, it pierced enemy shields and made them unusable by the weight and the curved shape of the shank stuck inside.
Second, it prevented the enemy from throwing it back because the bent shank did not allow the pilum to be thrown back with precision. Each legionary carried two pila in combat and training required both to be thrown in rapid succession before physical contact with the enemy. The formation into scutum, the famous tortoise where the soldiers closed their shields above their heads and on the sides creating a continuous cover of metal and wood was repeated until it could be executed in a few seconds in any condition. Caesar
mentions in his commentaries de bello Gallico that his legions formed the testudo so fast that the enemies were often paralyzed with surprise seeing the movement. This was not the result of a natural talent. It was the fruit of hundreds of repetitions. There was also specific training in field engineering. Every Roman legionary was to some extent an engineer.
They knew how to dig ditches, erect palisades, and maneuver artillery like the ballista and the onager. Caesar describes how his legions built a complete bridge over the Rhine in just 10 days using only local resources, not by specialized units, but by ordinary soldiers trained for this purpose. One of the least known aspects of the Roman legionary’s life is the administrative dimension of his existence.
The Roman army was a bureaucratic organization of impressive sophistication, and every soldier was a full actor in it. Marcus, like most soldiers of his time, probably knew how to read and write at a functional level. The Roman army required basic literacy of its recruits since at least the 2nd century before Christ. An extraordinary requirement in a world where the majority of the population was illiterate.
This was due to the fact that the Roman military administration relied on permanent documentation, daily reports, equipment registers, food inventory, letters to the family, engagement contracts, payment records. The salary of the ordinary legionary in the time of Trajan was 300 denarii per year paid in three installments. From this sum, the army automatically deducted the cost of food, equipment, and clothing.
A practice that deeply irritated the soldiers as evidenced by letters found in Egypt and at the fort of Vindolanda. The net salary was significantly lower than the gross, but there were compensations. At the end of 25 years of service, the legionary received an honorable discharge, a honesta missio, a cash bonus called premia, which in the time of Trajan was equivalent to 12 years of gross salary, and if he was an auxiliary or non-citizen, full and complete Roman citizenship for him and his children.
The camp also had a central office, the principia, where the treasury of the legion, the sacred standards, aquila and signa, and the administrative records were located. Soldiers who developed writing skills could be detached to work in this office as libarii or military scribes benefiting from a supplementary salary and escaping the most tedious tasks of construction and cleaning because the Roman camp also had to be constantly maintained.
Hygiene was a military priority. Not for aesthetic reasons, but for practical reasons. Armies living packed together are vulnerable to infectious diseases and an epidemic could destroy a legion more effectively than any enemy. The Roman camp had collective latrines with running water systems for washing. Public baths balnea for the regular bathing of soldiers and plan drainage systems to avoid the accumulation of stagnant water.
Marcus had the obligation to participate in the cleaning rotations of the castra. Digging new evacuation ditches. Keeping the corridors swept. Ensuring the proper functioning of the latrines. The guard system in the Roman camp was another aspect that distinguished the army of Rome from practically all its contemporaries.
The security of the castra was a collective responsibility and the consequences of negligence were deadly. The day was divided into eight watches of three hours each. Four daytime and four nighttime. Each soldier performed at least one watch in each 24-hour cycle. More often when the unit was in hostile territory.
The officer on duty regularly circulated to the guard post carrying a wooden tablet tessera with a password. A different password for each watch. Every guard had to know the password and present it correctly when the officer arrived. Polybius describes with blood-chilling precision the fate of the guard caught asleep at his post.
The man was subjected to the fustuarium by his own contubernium. Once again, the collective punishment applied by the comrades themselves. The logic was chilling in its efficiency. By making the whole group responsible for the conduct of each of its members. The Roman army created a system of mutual surveillance that dispense with additional supervisors.
The soldiers watched each other because the consequences of the fault of one fell on all. The signal for the beginning and end of each watch was transmitted by the horn and trumpet system of the camp. The cornicen horn blower and the tubicen tuba blower, the instrument with a long tube that the Romans used in more [music] formal context, were specialized positions within the legion.
Each signal had a specific and immediately recognizable [music] musical pattern. A different signal to change the guard, another to form the battle line, another for retreat, another to advance at a marching pace, another for the charge. On the battlefield where shouted orders [music] were inaudible a few meters away.
This musical language was the communication system that kept dozens of cohorts, the tactical units of about 500 men, in coordinated movement. It is easy to be tempted to imagine that the life of the Roman legionary was a purely martial existence, without room for more subtle human dimensions. Historical evidence tells a very different and much richer story.
Permanent Roman camps, in particular those that had existed for decades on the borders of the Rhine, the Danube, and in Britain, developed around them real towns called canabae. These civil communities emerged organically around the castra and welcomed merchants, artisans, prostitutes, tavern keepers, soldiers’ families, and all the service providers that a population of several thousand men requires.
Marcus, like most career soldiers, probably had what the Romans called a contubernalis, a life companion, a woman with whom he lived in a stable relationship, but not legally recognized as a wife because legionaries did not have the right to contract legal marriage during their active service.
This prohibition, which lasted from the Republican period until its revocation by Emperor Septimius Severus in 197 after Christ did not prevent stable long-term relationships, but created significant legal complications for the children born from these unions, who were technically illegitimate until the retirement of the father.
Gambling was a universal passion among Roman soldiers. Dice at tesserae, made of bone or ivory, have been found on practically all Roman archaeological sites from Egypt to Scotland. There were board games, the ludus latrunculorum, a strategy game similar to chess, was particularly popular and bets on javelin throwing and wrestling tournaments.
Compulsive gambling was a recognized problem. Several Roman laws tried to regulate betting between soldiers with limited success. The baths of the camp were the center of social life. These were not simple bath facilities. These were places where business was done, where friendships were made and where politics was discussed.
The process began at the tepidarium, the warm room, moved to the caldarium, the hot room with a heated pool, and ended at the frigidarium, the plunge into cold water to tighten the pores. Civilian attendants often worked in the baths of the castra, offering massages and applying perfumed oils for a modest fee.
Everything described so far happened during garrison periods, when the legion was stationed in a permanent castra. But the Roman army was in constant movement, and the conditions of marching on campaign were radically different. When the legion marched, it took with it practically everything it needed to establish a new camp at destination.
Each soldier carried, in addition to his combat equipment, a marching pack, the sarcina, with wooden stakes for the palisade, digging tools, rations for 3 days, and cooking utensils. The total weight easily reached 40 kg. The Roman soldiers were, for this reason, nicknamed Marius’s mules, muli Mariani, in reference to General Gaius Marius, who in the 2nd century before Christ had considerably increased the individual equipment of each soldier, reducing dependence on slow and vulnerable baggage trains.
The result was an army that moved at an impressive speed. Standard march covered 25 to 35 km per year, and Caesar mentions that in an emergency his legions marched 50 km in a single day. The reality of Roman battles, seen through the eyes of the ordinary soldier, was much more chaotic, noisy, nauseating, and terrifying than any cinematographic representation can render.
Before combat, the soldiers performed collective religious rituals, animal sacrifices, prayers to Mars and to the Dei Militares, the specific gods of the army. The augurs observed the behavior of birds and the entrails of sacrificed animals to determine if the auspices were favorable. This was not an empty superstition.
It was a collective psychological mechanism that created cohesion and reduced individual fear by inserting each soldier into a larger narrative where the gods themselves participated in the battle. The basic Roman formation was the triplex acies, three staggered lines, the hastati in the first line, the principes in the middle line, and the triarii in the rear guard.
Each line serving as a reserve for the previous one. In the practice of the year 117 after Christ, this structure had evolved, but the fundamental principle remained. The depth of the formation allowed fresh troops to continuously replace the exhausted ones in the first line, maintaining pressure on the enemy without completely exhausting any particular unit.
The moment preceding the battle was described by Roman veterans as a singular state of hyperfocus, where fear transformed into something [music] close to anesthesia. Livy, or describing battles of the Republic, mentioned soldiers who reported not having felt serious wounds in the heat of action, discovering them only hours later.
Modern neurosciences have an explanation for this. The stress response releases hormones that temporarily suppress the perception of pain. But for Marcus and his comrades, it was simply the lived experience of war. The advance began with the throwing of the pila, the two spears that all legionaries carried. Then, the [clears throat] final run of 15 to 20 m towards the enemy, followed by the clash of shields.
The scutum striking the enemy shield with all the force and mass of the soldier behind. The immediate objective was not to kill, but to destabilize, force the enemy to step back half a step, open a breach, create space for the thrust of the gladius that followed. The smell of a Roman battle was something survivors never forgot.
Blood mixed with sweat and human excrement. Many soldiers lost control of their sphincters in the terror of combat. Torch smoke, the metallic smell of iron and the particular smell of open wounds exposed to the sun. The noise was deafening. War cries, metallic clash of weapons, groans of the wounded, orders shouted by centurions and high notes of horns transmitting orders above the chaos.
The centurions, the intermediate officers commanding units of 80 men, were the nervous system of the Roman army in combat. Positioned at the far right of their centuries, where they were most exposed, they fought alongside their men rather than commanding from secure positions in the rear.
This created an extraordinary bond of trust between commanders and soldiers, but also meant disproportionately high mortality rates among centurions. Polybius observes that the Roman army chose men for the centurion and not on the basis of isolated bravery, but on the basis of a specific combination of physical courage and emotional stability.
Men who kept a cool head under extreme pressure. The Roman military service lasted 25 years for legionaries and after the reforms of Augustus at the end of the 1st century before Christ, it was a formal engagement with a start date, established conditions and clearly defined benefits at the end. Most recruits entered the army between 18 and 22 years old, which means that the active life of a legionary like Marcus extended into his 40s.
An age that in the ancient world was already considered advanced maturity. Throughout this career, there were possibilities for advancement. The simple soldier could become an immunis, a category of specialists exempted from the most tedious tasks thanks to specific skills like medicine, carpentry or writing. And then principis, a non-commissioned officer with a small command and extra pay.
Above were the centurions whose salary was about 15 times higher than that of an ordinary soldier. For soldiers showing exceptional courage in combat, there was a system of military decorations, the corona civica. An oak wreath was awarded to soldiers who had saved the life of a Roman citizen in combat.
The corona muralis went to the first to scale the walls of a besieged city. In addition to wreaths, there were torques, bracelets and fellery, decorative discs worn on the armor during military parades. War wounds were inevitable over a long career. The Roman military doctors, medici, were probably the most experienced health professionals in the ancient world given the number of traumas they treated.
Archaeological discoveries have revealed sophisticated surgical [music] kits, forceps, scalpels, projectile extraction tools and suturing needles. Roman medicine used wine as an antiseptic, honey to promote healing and wooden splints to immobilize fractures. The retirement of a legionary was a profound transformation.
After 25 years of an entirely regulated existence, the veteran found himself with a sum of money and very often a plot of land in a Roman colony. These colonies, like Colonia Agrippina today, Cologne in Germany, or Augusta Emerita today, Merida in Spain, were deliberate instruments of Romanization. By distributing veterans in the conquered territories, Rome created centers of Roman culture and Latin language disseminated across the world after diving into a complete day of the life of a Roman legionary in the year 117 after Christ, an inevitable question
emerges. Why does the history of the Roman army continue to fascinate so much 2,000 years later? The answer lies in the scale and consistency of what was built. For more than five centuries, the Roman army was the most organized, most disciplined, and most professional force in the Western world.
In the Roman battles that this army fought from Zama against Carthage in 202 before Christ to the wars of Trajan against the Dacians between 101 and 106 after Christ, ordinary legionaries like Marcus were the actors in a transformation of the world that still shapes us today. The cities born around Roman camps have become some of the largest metropolises in modern Europe.
The systems of roads, aqueducts, and territorial administration that the Roman army built and maintained have left physical traces still identifiable in archaeological excavations and urban layouts. The Latin that the soldiers spoke, the sermo castrensis, the colloquial Latin of the camps and the direct ancestor of Portuguese, Spanish, French, Italian, and Romanian.
The history of the Roman Empire told through the eyes of these soldiers is ultimately a human story about what people are capable of enduring, building and destroying when they are organized by a powerful collective goal. Marcus Aurelius Verus, or any of the thousands of real men he represents, did not think in terms of civilizational legacy, he thought about the morning wheat, the night guard duty, the comrades by his side in the formation, and yet, the sum of thousands of these days lived by millions of men over the centuries built something that
we have not yet finished understanding fully. Ancient Rome was above all a human experience of extraordinary dimensions. And each time we dig an archaeological site, read a letter preserved on papyrus, or study the layout of a Roman camp, we’re in a certain way recovering a fragment of this experience, giving back a voice to men who walked, fought, ate, smiled, and whose legacy projects its shadow over our world.
If you made it this far, you already know more about the real life of a Roman soldier than most people who studied history. But one question remains unanswered among the 10 aspects we explored today. Waking up before dawn, the wheat-based diet, training without end, administrative obligations, guard duties, social life in the camp, the hardships of the march, the brutal reality of battles, career evolution, and the lasting legacy.
