Introduction
During the growth of the ancientย civilizations,ย ancient technologyย was the result from advances inย engineeringย inย ancient times. These advances in theย history of technologyย stimulated societies to adopt new ways of living and governance.
This article includes the advances in technology and the development of several engineering sciences inย historic timesย before theย Middle Ages, which began after theย fall of the Western Roman Empireย inย ADย 476,[1][2]ย the death ofย Justinian Iย in the 6th century,[3]ย the coming ofย Islamย in the 7th century,[4]ย or the rise ofย Charlemagneย in the 8th century.[5]
Africa
Technology in Africa has a history stretching to the beginning of the human species, stretching back to the first evidence ofย tool useย by hominid ancestors in theย areas of Africaย where humans are believed to have evolved. Africa saw the advent of some of the earliestย ironworkingย technology in theย Aรฏr Mountainsย region of what is todayย Nigerย and the erection of some of the world’s oldest monuments, pyramids, and towers inย Egypt,ย Nubia, andย North Africa. In Nubia and ancient Kush, glazed quartzite and building in brick were developed to a greater extent than in Egypt. Parts of the East Africanย Swahili Coastย saw the creation of the world’s oldestย carbon steelย creation with high-temperatureย blast furnacesย created by theย Haya peopleย of Tanzania.
Mesopotamia
The Mesopotamians were one of the first to enter theย Bronze Ageย in the world. Early on they usedย copper,ย bronzeย andย gold, and later they usedย iron. Palaces were decorated with hundreds of kilograms of these very expensive metals. Also, copper, bronze, and iron were used forย armorย as well as for different weapons such asย swords,ย daggers,ย spears, andย maces.

Perhaps the most important advance made by theย Mesopotamiansย was theย invention of writingย by theย Sumerians. With the invention of writing came the first recorded laws called theย Code of Hammurabiย as well as the first major piece of literature called theย Epic of Gilgamesh.
Several of the six classicย simple machinesย were invented in Mesopotamia.[6]ย Mesopotamians have been credited with the invention of theย wheel. Theย wheel and axleย mechanism first appeared with theย potter’s wheel, invented inย Mesopotamiaย (modern Iraq) during the 5th millennium BC.[7]ย This led to the invention of theย wheeled vehicleย in Mesopotamia during the early 4th millennium BC. Depictions of wheeledย wagonsย found onย clay tabletย pictographsย at theย Eanna districtย ofย Urukย are dated between 3700 and 3500 BC.[8]ย Theย leverย was used in theย shadoofย water-lifting device, the firstย craneย machine, which appeared in Mesopotamia circa 3000 BC.[9]ย and then inย ancient Egyptian technologyย circa 2000 BC.[10]ย The earliest evidence ofย pulleysย date back to Mesopotamia in the early 2nd millennium BC.[11]
Theย screw, the last of the simple machines to be invented,[12]ย first appeared in Mesopotamia during theย Neo-Assyrianย period (911-609) BC.[11]ย According to the assyriologistย Stephanie Dalley, the earliestย pumpย was theย screw pump, first used byย Sennacherib, King ofย Assyria, for theย water systemsย at theย Hanging Gardens of Babylonย andย Ninevehย in the 7th century BC. This attribution, however, is disputed by the historianย John Peter Oleson.[13][14]
The Mesopotamians used aย sexagesimalย number system with the base 60 (like we use base 10). They divided time up by 60s including a 60-second minute and a 60-minute hour, which we still use today. They also divided up the circle into 360 degrees. They had a wide knowledge of mathematics including addition, subtraction, multiplication, division, quadratic and cubic equations, and fractions. This was important in keeping track of records as well as in some of their large building projects. The Mesopotamians had formulas for figuring out the circumference and area for different geometric shapes like rectangles, circles, and triangles. Some evidence suggests that they even knew the Pythagorean Theorem long before Pythagoras wrote it down. They may have even discovered the number for pi in figuring the circumference of a circle.
Babylonian astronomyย was able to follow the movements of the stars, planets, and the Moon. Application of advanced math predicted the movements of several planets. By studying the phases of the Moon, the Mesopotamians created the firstย calendar. It had 12 lunar months and was the predecessor for both theย Jewishย andย Greek calendars.
Babylonian medicineย used logic and recorded medical history to be able to diagnose and treat illnesses with various creams and pills. Mesopotamians had two kinds of medical practices, magical and physical, and would often use both practices on the same patient.[15]
The Mesopotamians made many technological discoveries. They were the first to use the potter’s wheel to make better pottery, they used irrigation to get water to their crops, they used bronze metal (and later iron metal) to make strong tools and weapons, and used looms to weave cloth from wool.
The Jerwan Aqueduct (c. 688ย BC) is made with stone arches and lined with waterproof concrete.[16]
For later technologies developed in the Mesopotamian region, now known asย Iraq, seeย Persiaย below for developments under the ancientย Persian Empire, and theย Inventions in medieval Islamย andย Arab Agricultural Revolutionย articles for developments under the medieval Islamicย Caliphates.
Egypt

Theย Egyptiansย invented and used many simple machines, such as theย rampย to aid construction processes. They were among the first to extractย goldย by large-scale mining usingย fire-setting, and the first recognisableย map, theย Turin papyrusย shows the plan of one such mine inย Nubia.
Theย Egyptiansย are known for buildingย pyramidsย centuries before the creation of modern tools. Historians and archaeologists have found evidence that theย Egyptian pyramidsย were built using three of what is called theย Six Simple Machines, from which all machines are based. These machines are theย inclined plane, theย wedge, and theย lever, which allowed the ancient Egyptians to move millions of limestone blocks which weighed approximately 3.5 tons (7,000 lbs.) each into place to create structures like theย Great Pyramid of Giza, which is 481 feet (147 meters) high.[17]
Egyptianย paper, made fromย papyrus, andย potteryย were mass-produced and exported throughout the Mediterranean basin. Theย wheel, however, did not arrive until foreign invaders introduced theย chariot. They developed Mediterraneanย maritimeย technology including ships and lighthouses. Early construction techniques utilized by the Ancient Egyptians made use of bricks composed mainly of clay, sand, silt, and other minerals. These constructs would have been vital in flood control and irrigation, especially along the Nile delta.[18]
Theย screw pumpย is the oldest positive displacement pump.[19]ย The first records of a screw pump, also known as aย water screwย orย Archimedes’ screw, dates back toย Ancient Egyptย before the 3rd century BC.[19][20]ย The Egyptian screw, used to lift water from theย Nile, was composed of tubes wound round a cylinder; as the entire unit rotates, water is lifted within the spiral tube to the higher elevation. A later screw pump design from Egypt had a spiral groove cut on the outside of a solid wooden cylinder and then the cylinder was covered by boards or sheets of metal closely covering the surfaces between the grooves.[19]ย The screw pump was later introduced from Egypt to Greece.[19]

Indian Subcontinent

Theย history of science and technology in the Indian subcontinentย dates back to the earliest civilizations of the world. Theย Indus Valley civilizationย yields evidence ofย mathematics,ย hydrography,ย metrology,ย metallurgy,ย astronomy,ย medicine,ย surgery,ย civil engineeringย and sewage collection and disposal being practiced by its inhabitants.
Theย Indus Valley civilization, situated in a resource-rich area (in modernย Pakistanย and northwesternย India), is notable for its early application of city planning,ย sanitation technologies, andย plumbing.[21]ย Cities in the Indus Valley offer some of the first examples of closed gutters, public baths, and communal granaries.
Theย Takshashilaย University was an important seat of learning in the ancient world. It was the center of education for scholars from all over Asia. Manyย Greek, Persian andย Chineseย students studied here under great scholars includingย Kautilya, Panini,ย Jivaka, and Vishnu Sharma.
The ancient system of medicine in India,ย Ayurvedaย was a significant milestone in Indian history. It mainly uses herbs as medicines. Its origins can be traced back to origin ofย Atharvaveda. Theย Sushruta Samhitaย (400 BC) by Sushruta has details about performing cataract surgery, plastic surgery, etc.
Ancient India was also at the forefront of seafaring technology – a panel found atย Mohenjo-daro, depicts a sailing craft. Ship construction is vividly described in the Yukti Kalpa Taru, an ancient Indian text on Shipbuilding. (The Yukti Kalpa Taru had been translated and published byย Prof. Aufrechtย in his ‘Catalogue of Sanskritย Manuscripts’).
Indian construction and architecture, called ‘Vaastu Shastra’, suggests a thorough understanding of materials engineering, hydrology, and sanitation. Ancient Indian culture was also pioneering in its use of vegetable dyes, cultivating plants includingย indigoย andย cinnabar. Many of the dyes were used in art and sculpture. The use ofย perfumesย demonstrates some knowledge ofย chemistry, particularlyย distillationย and purification processes.
China

Theย history of science and technology in Chinaย shows significant advances in science, technology, mathematics, and astronomy.ย Traditional Chinese medicine, acupuncture and herbal medicine were also practiced. Theย Four Great Inventionsย of China: theย compass,ย gunpowder, papermaking, and printing were among the most important technological advances, only known in Europe by the end of the Middle Ages.
According to the Scottish researcherย Joseph Needham, the Chinese made many first-known discoveries and developments. Major technological contributions from China include earlyย seismologicalย detectors,ย matches,ย paper, the double-actionย piston pump,ย cast iron, the ironย plough, the multi-tubeย seed drill, theย suspension bridge,ย natural gasย as fuel, theย magnetic compass, theย raised-relief map, theย propeller, theย crossbow, theย south-pointing chariot, andย gunpowder. Other Chinese discoveries and inventions from the Medieval period, according to Joseph Needham’s research, include:ย block printingย andย movable type, phosphorescent paint, and theย spinning wheel.
The solid-fuelย rocketย was invented in China about 1150 AD, nearly 200 years after the invention ofย black powderย (which acted as the rocket’s fuel). At the same time that theย age of explorationย was occurring in the West, the Chinese emperors of theย Ming Dynastyย also sent ships,ย some reaching Africa. But the enterprises were not further funded, halting further exploration and development. Whenย Ferdinand Magellan’s ships reachedย Bruneiย in 1521, they found a wealthy city that had been fortified by Chinese engineers, and protected by aย breakwater.ย Antonio Pigafettaย noted that much of the technology of Brunei was equal to Western technology of the time. Also, there were more cannons in Brunei than on Magellan’s ships, and the Chinese merchants to the Brunei court had sold themย spectaclesย andย porcelain, which were rarities in Europe.
Persian Empire

Theย Qanat, a water management system used for irrigation, originated inย Iranย before theย Achaemenid periodย of Persia. The oldest and largest known qanat is in the Iranian city ofย Gonabadย which, after 2,700ย years, still provides drinking and agricultural water to nearly 40,000ย people.[22]
The earliest evidence ofย water wheelsย andย watermillsย date back to theย ancient Near Eastย in the 4th century BC,[23]ย specifically in theย Persian Empireย before 350ย BC, in the regions of Mesopotamia (Iraq) andย Persiaย (Iran).[24]ย This pioneering use ofย water powerย constituted the first human-devised motive force not to rely on muscle power (besides theย sail).
In the 7thย century AD, Persians inย Afghanistanย developed the first practicalย windmills. For later medieval technologies developed inย Islamic Persia, seeย Inventions in medieval Islamย andย Arab Agricultural Revolution.
Mesoamerica and the Andean Region
Lacking suitable beasts of burden and inhabiting domains often too mountainous or boggy for wheeled transport, the ancient civilizations of the Americas did not develop wheeled transport or the mechanics associated with animal power. Nevertheless, they produced advanced engineering including above ground and underground aqueducts, quake-proof masonry, artificial lakes, dykes, ‘fountains,’ pressurized water,[25]ย road ways and complex terracing. Equally, gold-working commenced early in Peru (2000 BC),[26]ย and eventually copper, tin, lead and bronze were used.[27]ย Although metallurgy did not spread to Mesoamerica until the Middle Ages, it was employed here and in the Andes for sophisticated alloys and gilding.ย Perhaps the best-known Mesoamerican invention was rubber, which was used to create rubber bands, rubber bindings, balls, syringes, ‘raincoats,’ boots, and waterproof insulation on containers and flasks.
Hellenistic Mediterranean
Theย Hellenistic periodย ofย Mediterranean historyย began in the 4th century BC withย Alexander’s conquests, which led to the emergence of aย Hellenistic civilizationย representing a synthesis ofย Greekย andย Near-Easternย cultures in theย Eastern Mediterraneanย region, including theย Balkans,ย Levantย andย Egypt.[28]ย Withย Ptolemaic Egyptย as its intellectual center and Greek as the lingua franca, the Hellenistic civilization includedย Greek,ย Egyptian,ย Jewish,ย Persianย andย Phoenicianย scholars and engineers who wrote in Greek.[29]
Hellenistic technology made significant progress from the 4th century BC, continuing up to and including the Roman period. Some inventions that are credited to the ancient Greeks are the following: bronze casting techniques,ย water organย (hydraulis), andย torsion siege engine. Many of these inventions occurred late in the Hellenistic period, often inspired by the need to improve weapons and tactics in war.
Hellenistic engineers of the Eastern Mediterranean were responsible for a number of inventions and improvements to existing technology.ย Archimedesย invented several machines. Hellenistic engineers often combined scientific research with the development of new technologies. Technologies invented by Hellenistic engineers include theย ballistae, theย piston pump, and primitiveย analog computersย like theย Antikythera mechanism. Hellenistic architects builtย domes, and were the first to explore theย Golden ratioย and its relationship with geometry and architecture.
Other Hellenistic innovations include torsion catapults, pneumatic catapults, crossbows, rutways, organs, the keyboard mechanism, differential gears, showers, dry docks, diving bells, odometer and astrolabes. In architecture, Hellenistic engineers constructed monumental lighthouses such as theย Pharosย and devised central heating systems. Theย Tunnel of Eupalinosย is the earliest tunnel which has been excavated with a scientific approach from both ends.
Automata like automatic doors and other ingenious devices were built by Hellenistic engineers asย Ctesibiusย andย Philo of Byzantium. Greek technological treatises were scrupulously studied and advanced by later Byzantine, Arabic and Latin scholars, and provided some of the foundations for further technological advances in these civilizations.
Roman Empire

Benh LIEU SONG, Wikimedia CommonsTheย Roman Empireย expanded fromย Italiaย across the entireย Mediterranean regionย between the 1st century BC and 1st century AD. Its most advanced and economically productive provinces outside of Italia were theย Eastern Romanย provinces in theย Balkans,ย Asia Minor,ย Egypt, and theย Levant, withย Roman Egyptย in particular being the wealthiest Roman province outside of Italia.[30][31]
Roman technologyย supported Roman civilization and made the expansion of Roman commerce and Roman military possible over nearly a thousand years. The Roman Empire had an advanced set of technology for their time. Some of the Roman technology in Europe may have been lost during the turbulent eras of Late Antiquity and the Early Middle Ages. Roman technological feats in many different areas such as civil engineering, construction materials, transport technology, and some inventions such as theย mechanical reaperย went unmatched until the 19th century. Romans developed an intensive and sophisticated agriculture, expanded upon existing iron working technology, createdย lawsย providing for individual ownership, advanced stonemasonry technology, advancedย road-buildingย (exceeded only in the 19th century), military engineering, civil engineering, spinning and weaving and several different machines like theย Gallic reaperย that helped to increase productivity in many sectors of the Roman economy. They also developed water power through building aqueducts on a grand scale, using water not just for drinking supplies but also forย irrigation, poweringย water millsย and in mining. They used drainage wheels extensively in deep underground mines, one device being theย reverse overshot water-wheel. They were the first to applyย hydraulic miningย methods for prospecting for metal ores, and for extracting those ores from the ground when found using a method known asย hushing.

Roman engineers have builtย triumphal arches,ย amphitheatres,ย aqueducts,ย public baths,ย true arch bridges,ย harbours,ย dams, vaults andย domesย on a very large scale across their Empire. Notable Roman inventions include theย book (Codex),ย glass blowingย andย concrete. Because Rome was located on a volcanic peninsula, with sand which contained suitable crystalline grains, theย concreteย which the Romans formulated was especially durable. Some of their buildings have lasted 2000 years, to the present day. Roman society had also carried over the design of a door lock with tumblers and springs from Greece. Like many other aspects of innovation and culture that were carried on from Greece to Rome, the lines between where each one originated from have become skewed over time. These mechanisms were highly sophisticated and intricate for the era.[32]
Roman civilization was highly urbanized by pre-modern standards. Many cities of theย Roman Empireย had over 100,000 inhabitants with the capital Rome being the largest metropolis of antiquity. Features of Roman urban life included multistory apartment buildings calledย insulae, street paving, public flush toilets, glass windows andย floor and wall heating. The Romans understoodย hydraulicsย and constructedย fountainsย and waterworks, particularlyย aqueducts, which were the hallmark of their civilization. They exploited water power by buildingย water mills, sometimes in series, such as the sequence found atย Barbegalย in southern France and suspected on theย Janiculumย in Rome. Someย Roman bathsย have lasted to this day. The Romans developed many technologies which were apparently lost in theย Middle Ages, and were only fully reinvented in the 19th and 20th centuries. They also left texts describing their achievements, especiallyย Pliny the Elder,ย Frontinusย andย Vitruvius.
Other less known Roman innovations includeย cement, boat mills, archย damsย and possiblyย tide mills.

In Roman Egypt,ย Heron of Alexandriaย invented theย aeolipile, a basicย steam-poweredย device, and demonstrated knowledge of mechanic and pneumatic systems. He was also the first to experiment with aย wind-poweredย mechanical device, a windwheel. He also described aย vending machine. However, his inventions were primarily toys, rather than practical machines.
