The Roman Empire had the most advanced set of technologies of their time which in most areas was lost during the turbulent eras of Late Antiquity and the Early Middle Ages. Gradually, some of the technological feats of the Romans were rediscovered and/or improved upon and some others others - such as firearms, advanced sailing ship technologies and moveable type printing, went ahead of what the Romans had done by the end of the Middle Ages and the beginning of the Modern Era. However the roman technological feats of many different areas, like civil engineering, construction materials, transport technology, and some inventions such as the mechanical reaper went unmatched until the 19th century.

Process of acquiring new technology

Foreign influence

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 perfected the stone arch, and used it in bridges as well as buildings. Etruscan cities had paved streets and sewer systems, unlike most Hellenic city-states, which had muddy roads and no sewers save filthy open-air trenches. Map showing the extent of the Etruscan civilization and the twelve Etruscan League cities. ...

A great part of later Roman technologies were taken directly from Greek civilization. Much of the implements of land based Roman armies came out of the experimentation and the new developments in weapons of the Hellenistic wars that raged for decades between the successors of Alexander the Great. Most of the Greek city states abandoned the new weapons^{[citation needed]} developed during these wars, reverting to simpler Macedonian arms and tactics of old, while the Romans took the newest developments and adapted them to their social forms. Alexander the Great (Greek: ,[1] Megas Alexandros; July 356 BC–June 11, 323 BC), also known as Alexander III, king of Macedon (336–323 BC), was one of the most successful military commanders in history. ...

Roman fleets were based directly on Carthagen quinqueremes but were quickly adapted with the Roman innovation of the corvus (Polybius 1,21-23). A quinquireme was a galley, a warship propelled by oars, developed from the earlier trireme. ... See: Corvus is the genus name of large Passerine birds including the raven and crow species. ...

Slowness of innovation

A 2000-year-old iron Roman hoe blade.

Roman society was conservative and had little regard for abstract thought. Roman science was virtually non-existent, especially compared with Hellenistic science. Romans thought of themselves as practical, so small scale innovation was common, much more common than taught in traditional history. Technology could and did evolve. But without science, step change innovation was almost impossible. The scale of the Empire did encourage the geographical spread of innovations. The ideal Roman citizen was an articulate veteran soldier who could wisely govern a large family household, which was supported by slave labor. Innovators did have some prestige; Pliny, for example, often records their names, or has some story to account for the innovation. Romans also knew enough history to be aware that technological change had occurred in the past and brought benefits. Military innovation was always valued. One text, De Rebus Bellicis, devoted to a number of paper, mainly military, innovations has come down to us.

The apparent period in which technological progress was fastest and greatest was during the 2nd century and 1st century BCE, which was the period in which Roman political and economic power greatly increased. By the 2nd century CE, Roman technology appears to have peaked and it would take nearly two thousand years for all of its technological advancements to be rediscovered by other civilizations. But our understanding of Roman technology is so dominated by Pliny's Natural History that our dating of technological advance may have major errors. By the beginning of the 1st century , most of what is considered today as typical Roman technology was invented and refined, such as: concrete, plumbing facilities, cranes, wagon technology, mechanized harvesting machines, domes, roman arches, wine and oil presses, and glass blowing.

Many new technologies never were fully used in the Empire, because of the relative scarcity of capital as well as older infrastructure and social issues. With our lack of information and with the benefit of hindsight it is always easy to lament the slow pace of change. But without a patent or copyright system there was little incentive to publish information. In the list below it becomes apparent that many innovations are only known from a single source. This suggests that there are many Roman technologies which are still unknown. The dating of almost all innovations becomes obscure when asides in poems have historical importance.

The energy constraint

All technology uses energy to transform an, usually material, object. The cheaper energy is, the wider the class of technologies that are considered economic. This is why technological history can be seen as a succession of ages defined by energy type i.e. human, animal, water, peat, coal, oil etc. This is a gross simplification which still has value. The Romans had water but not wind power. Although there were huge reserves of peat and coal in the Roman Empire, to be of use these reserves had to be easily transportable to the major urban centres. In this sense, the Romans lacked efficient fossil energy. The very early industrial revolution would rely on cheap fossil energy. First peat, that would fuel the Dutch Golden Age, then coal, mainly from the coalfield just north Hadrian's Wall which supplied London. Later the Ruhr coalfield would dominate. These easily worked fuel reserves were all just over the border from the Empire. The Romans worked almost all the coalfields of England that outcropped on the surface, by the end of the 2nd century (Smith 1997; 323). But after c.200 AD the commercial heart of the Empire was in Africa and the East. There was no large coalfield on the edge of the Mediterranean. If there had been, history may have been different. As it was, hypercausts did allow them to exploit very poor quality fuels like straw. The vast majority of today's technologies would not be economic at the Roman cost of energy. Rembrandt The Nightwatch (1642) The Dutch Golden Age (1584-1702) was a period in Dutch history, roughly spanning the 17th century, in which Dutch trade, science, and art were among the most acclaimed in the world. ...

The energy constraint shows up in archaeology by the extent to which energy intensive technologies exploited economies of scale e.g. pottery kilns with 40,000 items and baths with 1,600 bathers grew very big. La Graufesenque is an archaological site 2km from Millau, Aveyron, France at the junction of the Tarn and Dourbie rivers. ...

The failure of the Romans to develop steam power is sometimes put down to a lack of inventiveness. The energy constraint is a better reason. Hero of Alexandria had invented a steam turbine which was probably about as efficient as the first practical steam engine by Newcomen. The difference was that the Newcomen engine had a viable market draining coal mines, where energy was so cheap the inefficiency of the engine was not a constraint. Heros aeolipile Hero (or Heron) of Alexandria (c. ... Diagram of the Newcomen steam engine Thomas Newcomens atmospheric engine, today referred to as a Newcomen steam engine, was the first practical device to harness the power of steam to produce mechanical work. ...

Craft basis

Roman technology was largely based on a system of crafts. Although the term "engineering" is used today to describe the technical feats of the Romans. The Greek words used were mechanic or machine-maker or even mathematician which had a much wider meaning than now. There were a tiny number of engineers employed by the army. The most famous engineer of this period was Apollodorus of Damascus. Normally each trade, each group of artisans—stone masons, surveyors, etc.—within a project had its own practice of masters and apprentices, and all kept their trade secrets carefully, passing them on solely by word of mouth. Writers such as Vitruvius were the rare exceptions. Engineering is the design, analysis, and/or construction of works for practical purposes. ... Apollodorus of Damascus, a famous Greek architect, engineer, designer and sculptor, flourished during the 2nd century AD. He was a favourite of Trajan, for whom he constructed Trajans Bridge over the Danube (104) for the campaign in Dacia. ... It has been suggested that Artisan#Artisan guilds be merged into this article or section. ... An artisan, also called a craftsman,[1] is a skilled manual worker who uses tools and machinery in a particular craft. ... Marcus Vitruvius Pollio (born ca. ...

Most of what is known of Roman technology comes indirectly from archaeological work and from the third-hand accounts of Latin texts copied from Arabic texts, which were in turn copied from the Greek texts of scholars such as Hero of Alexandria or contemporary travelers who had observed Roman technologies in action. Writers like Pliny the Elder and Strabo had enough intellectual curiosity to make note of the inventions they saw during their travels, although their typically brief descriptions often arouse discussion as to their precise meaning.

The Romans made heavy use of aqueducts, bridges, and amphitheaters. They were also responsible for many innovations to roads, sanitation, and construction in general. Roman architecture in general was greatly influenced by the Etruscans. Most of the columns and arches seen in famous Roman architecture was adopted from the Etruscan civilization.

In the Roman Empire, cements made from pozzolanic ash/pozzolana and an aggregate made from pumice were used to make a concrete very similar to modern portland cement concrete. In 20s BC the architect Vitruvius described a low-water-content method for mixing concrete. The Romans found out that insulated glazing (or "double glazing") improved greatly on keeping buildings warm, and this technique was used in the construction of public baths.

The most used type of mill was the donkey mill. Its wide use was brought about by two factors:

• It could be built in any location in contrast to the water mills.

• donkeys were much cheaper and stronger than slaves, who operated the small and inefficient hand mills.

There were many types of presses to press olives, grapes and cloth. In the 1st century, Pliny the Elder reported the invention and subsequent general use of the new and more compact screw presses. However, the screw press was almost certainly not a Roman invention. It was first described by Hero of Alexandria, but may have already been in use when he mentioned it in his Mechanica III.

Roads

Via Appia, a road connecting the city of Rome to the Southern parts of Italy remains usable even today.

Main article: Roman road

The Romans primarily built roads for military purposes. They allowed the legions to be rapidly deployed in far reaches of the realm. However, their economic importance was probably also significant, although wagon traffic was often banned from the roads to preserve their military value. At its largest extent the total length of the Roman road network was 85 000 km (53 000 miles).

Way stations providing refreshments were maintained by the government at regular intervals along the roads. A separate system of changing stations for official and private couriers was also maintained. This allowed a dispatch to travel a maximum of 800 km (500 miles) in 24 hours by using a relay of horses.

The roads were constructed by digging a pit along the length of the intended course, often to bedrock. The pit was first filled with rocks, gravel or sand and then a layer of concrete. Finally they were paved with polygonal rock slabs. Roman roads are considered the most advanced roads built until the early 19th century. Bridges were constructed over waterways. The roads were resistant to floods and other environmental hazards. After the fall of the Roman empire the roads were still usable and used for more than 1000 years. Bedrock is the native consolidated rock underlying the Earths surface. ...

Aqueducts

Main article: Aqueduct

The Romans constructed numerous aqueducts to supply water to cities and industrial sites. The city of Rome itself was supplied by eleven aqueducts that provided the city with over 1 million cubic meters of water [1], sufficient to supply 3.5 million people [2] and with combined length of 350 km (260 miles).^[3] Most aqueducts were constructed below the surface with only small portions above ground supported by arches. The longest Roman aqueduct, 141 km (87 miles) in length, was built to supply the city of Carthage.^[4] Pont du Gard, France, a Roman aqueduct built circa 19 BC.

Roman aqueducts were built to remarkably fine tolerances, and to a technological standard that was not to be equalled until modern times. Powered entirely by gravity, they transported very large amounts of water very efficiently. Sometimes, where depressions deeper than 50 m had to be crossed, inverted siphons were used to force water uphill.^[2] Gravity is a force of attraction that acts between bodies that have mass. ... Inverted siphons are pressurized piplines that force water uphill. ...

Sanitation

Further information: Thermae

The Roman public baths, or thermae served hygienic, social and cultural functions. The baths contained three main facilities for bathing. After undressing in the apodyterium or changing room, Romans would proceed to the tepidarium or warm room. In the moderate dry heat of the tepidarium, some performed warm-up exercises and stretched while others oiled themselves or had slaves oil them. The tepidarium’s main purpose was to promote sweating to prepare for the next room, the caldarium or hot room. The caldarium, unlike the tepidarium, was extremely humid and hot. Temperatures in the caldarium could reach 40 degrees Celsius (104 degrees Fahrenheit). Many contained steam baths and a cold-water fountain known as the labrum. The last room was the frigidarium or cold room, which offered a cold bath for cooling off after the caldarium.

While heavy, intricate armour was not uncommon (cataphracts), the Romans perfected a relatively light, full torso armour made of segmented plates (lorica segmentata). This segmented armour provided flexibility and protection of most vital areas, and was not associated with the laborious craftwork that other armours (such as chainmail) were. Furthermore, the rest of the Roman soldier's equipment used similarly innovative and effective technology. The cataphract was a type of heavy cavalryman used primarily in eastern and southeastern Europe, in Anatolia and Iran from late antiquity up through the High Middle Ages. ... A reenactor dressed as a Roman soldier in lorica segmentata The lōrīca segmentāta was a type of armour primarily used in the Roman Empire, but the Latin name was first used in the 16th century (the ancient form is unknown). ...
