Technological history of the Roman military

Last updated

The technology history of the Roman military covers the development of and application of technologies for use in the armies and navies of Rome from the Roman Republic to the fall of the Western Roman Empire. The rise of Hellenism and the Roman Republic are generally seen as signalling the end of the Iron Age in the Mediterranean. Roman iron-working was enhanced by a process known as carburization. The Romans used the better properties in their armaments, and the 1,300 years of Roman military technology saw radical changes. The Roman armies of the early empire were much better equipped than early republican armies. Metals used for arms and armor primarily included iron, bronze, and brass. For construction, the army used wood, earth, and stone. The later use of concrete in architecture was widely mirrored in Roman military technology, especially in the application of a military workforce to civilian construction projects. [1]

Origins and development

Much of what is described as typically Roman technology, as opposed to that of the Greeks, comes directly from the Etruscan civilization, which was thriving to the North when Rome was just a small kingdom. The Etruscans had invented the stone arch, and used it in bridges as well as buildings. Some later Roman technologies were taken directly from Greek civilization.

After the absorption of the ancient Greek city states into the Roman Republic in 146 BC, the highly advanced Greek technology began to spread across many areas of Roman influence and supplement the Empire. This included the military advances that the Greeks had made, as well as all the scientific, mathematical, political and artistic developments.

New materials

However, the Romans made many significant technological advances, such as the invention of hydraulic cement and concrete. They used such new materials to great advantage in their structures, many of which survive to this day, like their masonry aqueducts, such as the Pont du Gard, and buildings, such as the Pantheon and Baths of Diocletian in Rome. Their methods were recorded by historical figures Vitruvius and Frontinus for example, who wrote handbooks to advise fellow engineers and architects. Romans knew enough history to be aware that widespread technological change had occurred in the past and brought benefits, as shown for example by Pliny the Elder's Naturalis Historia. That tradition continued as the empire grew in size and absorbed new ideas. Romans thought of themselves as practical, so small-scale innovation was common (such as the development of the ballista into the polybolos or repeating ballista). The traditional view is that their reliance on a plentiful slave labour force and a lack of a patent or copyright system have both been cited as reasons that there was little social or financial pressure to automate or reduce manual tasks. However, this view is being challenged by new research that shows they did indeed innovate, and on a wide scale. Thus the watermill had been known to the Greeks, but it was the Romans who developed their efficient utilisation. The set of mills at Barbegal in southern France were worked by a single aqueduct, which drove no fewer than 16 overshot mills built into the side of a hill. They probably were built by the army and supplied flour to a wide region. Floating mills were also used to exploit fast flowing rivers.

Mining

The Romans also used water power in an unexpected way during mining operations. It's known from the writings of Pliny the Elder that they exploited the alluvial gold deposits of north-west Spain soon after the conquest of the region in 25 BC using large-scale hydraulic mining methods. The spectacular gold mine at Las Medulas was worked by no fewer than seven long aqueducts cut into the surrounding mountains, the water being played directly onto the soft auriferous ore.

The outflow was channelled into sluice boxes, and the heavier gold collected on rough pavements. They also developed many deep mines, such as those for copper at Rio Tinto, where Victorian mining developments exposed the much earlier workings. Dewatering machines, such as Archimedean screws and reverse overshot water wheels, were found in situ, one of which is on show at the British Museum. Another fragmentary example was recovered from the Roman gold mine at Dolaucothi in west Wales, and is preserved at the National Museum of Wales in Cardiff. The army were at the forefront of development of gold mines, since the metal was imperial property, and developed the Dolaucothi mines from the outset by establishing a fort there that was known as Luentinum. They had the expertise to build the infrastructure of aqueducts and reservoirs, as well as control production.

The period in which technological progress was fastest and greatest was during the 2nd century and 1st century BC, which was the period in which Roman political and economic power greatly increased. By the 2nd century, Roman technology appears to have peaked.

Roman implementation of technology

The Romans advanced military technology significantly, and implemented it on a massive scale. From a few early models of ballista from Greek city-states the Romans adopted and improved the design, eventually issuing one to every century in the legions.

To facilitate this organization, an engineering corps was developed. An officer of engineers, or praefectus fabrum, is referenced in armies of the Late Republic, but this post is not verifiable in all accounts and may have simply been a military advisor on the personal staff of a commanding officer. [2] There were legion architects (whose rank is yet unknown), who were responsible for the construction of war machines. Ensuring that constructions were level was the job of the libratores, who would also launch missiles and other projectiles (on occasion) during battle. [3] The engineering corps was in charge of massive production, frequently prefabricating artillery and siege equipment to facilitate its transportation [4]

Vitruvius Roman writer, architect and engineer

Marcus Vitruvius Pollio, commonly known as Vitruvius, was a Roman author, architect, civil and military engineer during the 1st century BC, known for his multi-volume work entitled De architectura. His discussion of perfect proportion in architecture and the human body led to the famous Renaissance drawing by Leonardo da Vinci of Vitruvian Man. He was also the one who, in 40 BC, invented the idea that all buildings should have three attributes: firmitas, utilitas, and venustas, meaning: strength, utility, and beauty. These principles were later adopted by the Romans.

Ancient Roman architecture Ancient architecture

Ancient Roman architecture adopted the external language of classical Greek architecture for the purposes of the ancient Romans, but was different from Greek buildings, becoming a new architectural style. The two styles are often considered one body of classical architecture. Roman architecture flourished in the Roman Republic and even more so under the Empire, when the great majority of surviving buildings were constructed. It used new materials, particularly Roman concrete, and newer technologies such as the arch and the dome to make buildings that were typically strong and well-engineered. Large numbers remain in some form across the empire, sometimes complete and still in use to this day.

Sextus Julius Frontinus was a prominent Roman civil engineer, author, soldier and senator of the late 1st century AD. He was a successful general under Domitian, commanding forces in Roman Britain, and on the Rhine and Danube frontiers. A novus homo, he was consul three times. Frontinus ably discharged several important administrative duties for Nerva and Trajan. However, he is best known to the post-Classical world as an author of technical treatises, especially De aquaeductu, dealing with the aqueducts of Rome.

Hispania Tarraconensis

Hispania Tarraconensis was one of three Roman provinces in Hispania. It encompassed much of the northern, eastern and central territories of modern Spain along with the Norte Region of modern Portugal. Southern Spain, the region now called Andalusia, was the province of Hispania Baetica. On the Atlantic west laid the province of Lusitania, partially coincident with modern-day Portugal.

Dolaucothi Gold Mines

The Dolaucothi Gold Mines, also known as the Ogofau Gold Mine, are ancient Roman surface and underground mines located in the valley of the River Cothi, near Pumsaint, Carmarthenshire, Wales. The gold mines are located within the Dolaucothi Estate which is now owned by the National Trust.

<i>De architectura</i> Treatise on architecture by Vitruvius

De architectura is a treatise on architecture written by the Roman architect and military engineer Marcus Vitruvius Pollio and dedicated to his patron, the emperor Caesar Augustus, as a guide for building projects. As the only treatise on architecture to survive from antiquity, it has been regarded since the Renaissance as the first book on architectural theory, as well as a major source on the canon of classical architecture. It contains a variety of information on Greek and Roman buildings, as well as prescriptions for the planning and design of military camps, cities, and structures both large and small. Since Vitruvius published before the development of cross vaulting, domes, concrete, and other innovations associated with Imperial Roman architecture, his ten books give no information on these hallmarks of Roman building design and technology.

During the growth of the ancient civilizations, ancient technology was the result from advances in engineering in ancient times. These advances in the history of technology stimulated societies to adopt new ways of living and governance.

Roman engineering

The ancient Romans were famous for their advanced engineering accomplishments. Technology for bringing running water into cities was developed in the east, but transformed by the Romans into a technology inconceivable in Greece. The architecture used in Rome was strongly influenced by Greek and Etruscan sources.

Aqua Appia

The Aqua Appia was the first Roman aqueduct, constructed in 312 BC by the co-censors Gaius Plautius Venox and Appius Claudius Caecus, the same Roman censor who also built the important Via Appia.

Roman aqueduct

The Romans constructed aqueducts throughout their Republic and later Empire, to bring water from outside sources into cities and towns. Aqueduct water supplied public baths, latrines, fountains, and private households; it also supported mining operations, milling, farms, and gardens.

Las Médulas

Las Médulas is a historic gold-mining site near the town of Ponferrada in the comarca of El Bierzo. It was the most important gold mine, as well as the largest open-pit gold mine, in the entire Roman Empire. Las Médulas Cultural Landscape is listed by UNESCO as a World Heritage Site. Advanced aerial surveys conducted in 2014 using LIDAR have confirmed the wide extent of the Roman-era works.

The military engineering of Ancient Rome's armed forces was of a scale and frequency far beyond that of any of its contemporaries. Indeed, military engineering was in many ways institutionally endemic in Roman military culture, as demonstrated by the fact that each Roman legionary had as part of his equipment a shovel, alongside his gladius (sword) and pila (spears).

Barbegal aqueduct and mills

The Barbegal aqueduct and mills is a Roman watermill complex located on the territory of the commune of Fontvieille, near the town of Arles, in southern France. The complex has been referred to as "the greatest known concentration of mechanical power in the ancient world" and the sixteen overshot wheels are considered the biggest ancient mill complex.

Mining in Roman Britain

Mining was one of the most prosperous activities in Roman Britain. Britain was rich in resources such as copper, gold, iron, lead, salt, silver, and tin, materials in high demand in the Roman Empire. The Romans started panning and puddling for gold. The abundance of mineral resources in the British Isles was probably one of the reasons for the Roman conquest of Britain. They were able to use advanced technology to find, develop and extract valuable minerals on a scale unequaled until the Middle ages.

Roman technology

Roman technology is the collection of techniques, skills, methods, processes, and engineering practices utilized and developed by the civilization of ancient Rome .The Roman Empire was a technologically advanced civilization of antiquity. The Romans incorporated technologies from the Greeks, Etruscans, and Celts. The technology developed by a civilization is limited by the available sources of energy, and the Romans were no different in this sense. Accessible sources of energy determine the ways in which power is generated. The main types of power accessed by the ancient Romans were human, animal, and water.

Frequently used in mines and probably elsewhere, the reverse overshot water wheel was a Roman innovation to help remove water from the lowest levels of underground workings. It is described by Vitruvius in his work De architectura published circa 25 BC. The remains of such systems found in Roman mines by later mining operations show that they were used in sequences so as to lift water a considerable height.

Hushing

Hushing is an ancient and historic mining method using a flood or torrent of water to reveal mineral veins. The method was applied in several ways, both in prospecting for ores, and for their exploitation. Mineral veins are often hidden below soil and sub-soil, which must be stripped away to discover the ore veins. A flood of water is very effective in moving soil as well as working the ore deposits when combined with other methods such as fire-setting.

Metals and metal working had been known to the people of modern Italy since the Bronze Age. By 53 BC, Rome had expanded to control an immense expanse of the Mediterranean. This included Italy and its islands, Spain, Macedonia, Africa, Asia Minor, Syria and Greece; by the end of the Emperor Trajan's reign, the Roman Empire had grown further to encompass parts of Britain, Egypt, all of modern Germany west of the Rhine, Dacia, Noricum, Judea, Armenia, Illyria, and Thrace. As the empire grew, so did its need for metals.
