The following is a list of inventions, innovations or discoveries known or generally recognized to be Greek.

Alphabetical list of Greek inventions

A

• Acrolith: An acrolith is a composite sculpture made of stone together with other materials such as wood or inferior stone such as limestone, as in the case of a figure whose clothed parts are made of wood, while the exposed flesh parts such as head, hands, and feet are made of marble. The wood was covered either by drapery or by gilding. This type of statuary was common and widespread in Classical antiquity.
• Aerodynamics: Modern aerodynamics only dates back to the seventeenth century, but aerodynamic forces have been harnessed by humans for thousands of years in sailboats and windmills. Fundamental concepts of continuum, drag, and pressure gradients appear in the work of Aristotle and Archimedes.
• Air and water pumps: Ctesibius and various other Greeks of Alexandria of the period developed and put to practical use various air and water pumps which served a variety of purposes, such as a water organ and, by the 1st century AD, Heron's fountain.
• Alarm clock: The Hellenistic engineer and inventor Ctesibius (fl. 285–222 BC) fitted his clepsydras with a dial and pointer for indicating the time, and added elaborate "alarm systems, which could be made to drop pebbles on a gong, or blow trumpets (by forcing bell-jars down into water and taking the compressed air through a beating reed) at pre-set times" (Vitruv 11.11).
• Alchemy: Alchemy, a forerunner or Chemistry has its origin in Hellenistic Egypt.
• Algebra: Diophantus was an Alexandrian Greek mathematician and the author of a series of books called Arithmetica. These texts deal with solving algebraic equations, and have led, in number theory to the modern notion of Diophantine equation. In the context where algebra is identified with the theory of equations, Diophantus is credited as its inventor and thus the "father of algebra".
• Analog computer: n 1900–1901, the Antikythera mechanism was found in the Antikythera wreck. It is thought that this device was an analog computer designed to calculate astronomical positions and was used to predict lunar and solar eclipses based on Babylonian arithmetic-progression cycles. Whereas the Antikythera mechanism is considered a proper analog computer, the astrolabe (also invented by the Greeks) may be considered as a forerunner.
• Ancient Suez Canal: Opened by Greek engineers under Ptolemy II (283–246 BC), following earlier, probably only partly successful attempts.
• Anemoscope: Timosthenes invented the anemoscope.
• Anthropology: Many anthropological writers find anthropological-quality theorizing in the works of Classical Greece and Classical Rome. This emphasis on the inner life and on the importance of knowing oneself will become a core element of the philosophy of Socrates, whose Protagoras races the history of the Delphic inscription back to the Greek Seven Sages.
• Arch bridge: Possibly the oldest existing arch bridge is the Mycenaean Arkadiko bridge in Greece from about 1300 BC. The stone corbel arch bridge is still used by the local populace.
• Aqueduct: Although particularly associated with the Romans, aqueducts were likely first used by the Minoans around 2000 BCE. The Minoans had developed what was then an extremely advanced irrigation system, including several aqueducts.
• Astrolabe: First used around 300 BC by astronomers in Greece. Used to determine the altitude of objects in the sky.
• Aulos: Ancient Greek wind instrument.
• Automatic doors: Heron of Alexandria, a 1st-century AD inventor from Alexandria, Egypt, created schematics for automatic doors to be used in a temple with the aid of steam power.
• Automation: Ctesibius described a float regulator for a water clock, a device not unlike the ball and cock in a modern flush toilet. This was the earliest feedback controlled mechanism.

B

• Ballista: Greek missile weapon.
• Bathtub: The oldest bathtub was found on the island of Crete.
• Biochemistry: At its most comprehensive definition, biochemistry can be seen as a study of the components and composition of living things and how they come together to become life. In this sense, the history of biochemistry may therefore go back as far as the ancient Greeks.
• BlackBerry: Greek-Canadian businessman Mike Lazaridis founded BlackBerry, which created and manufactures the BlackBerry wireless handheld device. Lazaridis served in various positions including Co-Chairman and Co-CEO of BlackBerry from 1984 to 2012 and Board Vice Chair and Chair of the Innovation Committee from 2012 to 2013.
• Bouzouki: Popular musical instrument in Greece.
• Byzantine lyra: Medieval bowed string musical instrument in the Byzantine (Eastern Roman) Empire.

C

• Calipers: Earliest example found in the Giglio wreck near the Italian coast. The wooden piece already featured one fixed and a movable jaw.
• Caller ID: 1968, Theodore Paraskevakos, while working in as a communications engineer for SITA in Athens, Greece, began developing a system to automatically identify a telephone caller to a call recipient. Developing the method for the basis for modern-day Caller ID technology.
• Cameo (carving): A method of carving originating in Greece.
• Canal Lock: Built into Ancient Suez Canal under Ptolemy II.
• Cannon: Ctesibius of Alexandria invented a primitive form of the cannon, operated by compressed air.
• Catapult: The historian Diodorus Siculus mentions the invention of a mechanical arrow-firing catapult.
• Cella: The inner chamber of an ancient Greek or Roman temple in classical antiquity.
• Central heating: The Temple of Artemis at Ephesus was warmed by heated air that was circulated through flues laid in the floor, the first known central heating system. Central heating of buildings was later employed throughout the Greek world.
• Cetology: Observations about Cetacea have been recorded since at least classical times. Ancient Greek fishermen created an artificial notch on the dorsal fin of dolphins entangled in nets so that they could tell them apart years later.
• Chain drive: First described by Philo of Byzantium, the device powered a repeating crossbow, the first known of its kind.
• Cheesecake: The earliest attested mention of a cheesecake is by the Greek physician Aegimus who wrote a book on the art of making cheesecakes.
• Chelys: a stringed musical instrument, the common lyre of the ancient Greeks, which had a convex back of tortoiseshell or of wood shaped like the shell. The word chelys was used in allusion to the oldest lyre of the Greeks, which was said to have been invented by Hermes. According to the Homeric Hymn to Hermes, he came across a tortoise near the threshold of his mother's home and decided to hollow out the shell to make the soundbox of an instrument with seven strings.
• Chiton (costume): A chiton is a form of tunic that fastens at the shoulder, worn by men and women of Ancient Greece and Rome.
• Chryselephantine sculpture: sculpture made with gold and ivory. Chryselephantine cult statues enjoyed high status in Ancient Greece.
• Cithara: An ancient Greek musical instrument in the yoke lutes family. In modern Greek the word kithara has come to mean "guitar", a word which etymologically stems from kithara. The kithara was a seven-stringed professional version of the lyre, which was regarded as a rustic, or folk instrument, appropriate for teaching music to beginners. As opposed to the simpler lyre, the kithara was primarily used by professional musicians, called kitharodes. The kithara's origins are likely Anatolian. Popular in the eastern Aegean and ancient Anatolia.
• Claw of Archimedes: An ancient weapon devised by Archimedes to defend the seaward portion of Syracuse's city wall against amphibious assault. Although its exact nature is unclear, the accounts of ancient historians seem to describe it as a sort of crane equipped with a grappling hook that was able to lift an attacking ship partly out of the water, then either cause the ship to capsize or suddenly drop it. It was dropped onto enemy ships, which would then swing itself and destroy the ship.

• Climatology: The Greeks began the formal study of climate; in fact the word climate is derived from the Greek word klima, meaning "slope," referring to the slope or inclination of the Earth's axis. Arguably the most influential classic text on climate was On Airs, Water and Places written by Hippocrates.
• Clock tower: See Clock tower.
• Corinthian order: The Corinthian order is the last developed of the three principal classical orders of ancient Greek and Roman architecture.
• Compound Pulley: Archimedes of Syracuse invented the first compound pulleys.
• Counterweight mirror: Ctesibius' first invention was a counter-weighted mirror.
• Counterweight trebuchet: The earliest written record of the counterweight trebuchet, a vastly more powerful design than the simple traction trebuchet, appears in the work of the 12th-century historian Niketas Choniates. Niketas describes a stone projector used by future emperor Andronikos I Komnenos at the siege of Zevgminon in 1165. This was equipped with a windlass, an apparatus required neither for the traction nor hybrid trebuchet to launch missiles.
• Crane (machine): Labor-saving device that allowed the employment of small and efficient work teams on construction sites. Later winches were added for heavy weights.
• Cretan lyra: Greek pear-shaped, three-stringed bowed musical instrument, central to the traditional music of Crete and other islands in the Dodecanese and the Aegean Archipelago, in Greece.
• Curtain: Oldest curtains found in excavation sites at Olynthus, Greece.
• Cybernetics: Ctesibius and others such as Heron are considered to be some of the first to study cybernetic principles.

D

• Democracy: Led by Cleisthenes, Athenians established what is generally held as the first democracy in 508–507 BC. Cleisthenes is referred to as "the father of Athenian democracy."
• Differential gear: The Antikythera mechanism, from the Roman-era Antikythera wreck, employed a differential gear to determine the angle between the ecliptic positions of the sun and moon, and thus the phase of the moon.
• Disability ramp: Oldest disability ramp found in Greece for people with trouble walking.
• Discus throw: The sport of throwing the discus traces back to it being an event in the original Olympic Games of Ancient Greece.
• Doric order: The Doric order was one of the three orders of ancient Greek architecture.
• Double-action principal: Universal mechanical principle that was discovered and first applied by the engineer Ctesibius in his double action piston pump, which was later developed further by Heron to a fire hose.
• Dry dock: Invented in Ptolemaic Egypt, under Ptolemy IV Philopator.

E

• Ecology:Ancient Greek philosophers such as Hippocrates and Aristotle were among the first to record observations on natural history. However, they viewed life in terms of essentialism. Early conceptions of ecology, such as a balance and regulation in nature can be traced to Herodotus, who described one of the earliest accounts of mutualism in his observation of "natural dentistry".
• Elevator: The earliest known reference to an elevator is in the works of the Roman architect Vitruvius, who reported that Archimedes built his first elevator.
• Epidemiology: The Greek physician Hippocrates, known as the father of medicine, sought a logic to sickness; he is the first person known to have examined the relationships between the occurrence of disease and environmental influences.
• Epi-LASIK eye surgery: Greek ophthalmologist Ioannis Pallikaris, who was the first person to perform LASIK eye surgery in 1989, developed the improved epi-LASIK technique at the University of Crete.
• Escapement: Described by the Greek engineer Philo of Byzantium (3rd century BC) in his technical treatise Pneumatics (chapter 31) as part of a washstand automaton for guests washing their hands. Philon's comment that "its construction is similar to that of clocks" indicates that such escapement mechanisms were already integrated in ancient water clocks.
• Evidence-based medicine: The Greek medical schools at Knidos and Kos were the first to develop rational theories of disease disconnected from religion and superstition and advocate healing based on empirically verified cures.

F

• Feta: Feta cheese, specifically, is first recorded in the Byzantine Empire in Avicenna's Poem on Medicine under the name prósphatos (Greek: πρόσφατος, "recent" or "fresh"), and was produced by the Cretans and the Vlachs of Thessaly.
• Fire hose: Invented by Heron in the basis of Ctesibius' double action piston pump.Allowed for more efficient fire fighting.
• Fire pump: An early device used to squirt water onto a fire was known as a squirt or fire syringe. Hand squirts and hand pumps are noted before Ctesibius of Alexandria invented the first fire pump around the 2nd century B.C.
• Flamethrower: Greek fire, heated in a brazier and pressurized by means of a pump, was ejected by an operator through a siphon in any direction against the enemy.Alternatively, it could be poured down from swivel cranes or hurled in pottery grenades.
• Flying machine: As only described in the writings of Aulus Gellius five centuries after him, he was reputed to have designed and built the first artificial, self-propelled flying device, a bird-shaped model propelled by a jet of what was probably steam, said to have actually flown some 200 meters.
• Fore-and-aft rig: Spritsails, the earliest fore-and-aft rigs, appeared in the 2nd century BC in the Aegean Sea on small Greek craft.
• Frappé coffee: The Greek version of café frappé, using instant coffee, was invented in 1957 at the Thessaloniki International Fair.

G

• Geography: Building on the mapmaking practices of the Near East, the philosopher Anaximander, a student of Thales, was the first known person to produce a scale map of the known world,while some decades later Hecataeus of Miletus was the first to combine map-making with vivid descriptions of the people and landscapes of each location, taken from interviews with sailors and other travellers, initiating a field of study which Eratosthenes later named γεωγραφία (geography).
• Geology: The study of the physical material of the Earth dates back at least to ancient Greece when Theophrastus wrote the work Peri Lithon (On Stones).
• Geomorphology: The study of landforms and the evolution of the Earth's surface can be dated back to scholars of Classical Greece. Herodotus argued from observations of soils that the Nile delta was actively growing into the Mediterranean Sea, and estimated its age. Aristotle speculated that due to sediment transport into the sea, eventually those seas would fill while the land lowered. He claimed that this would mean that land and water would eventually swap places, whereupon the process would begin again in an endless cycle.
• Gimbal: The inventor Philo of Byzantium described an eight-sided ink pot with an opening on each side, which can be turned so that any face is on top, dip in a pen and ink it-yet the ink never runs out through the holes of the side. This was done by the suspension of the inkwell at the center, which was mounted on a series of concentric metal rings which remained stationary no matter which way the pot turns itself.
• Glasses: The precursor of glasses are the visual aid devices of ancient Greece. Scattered evidence exists for use of visual aid devices in Greek and Roman times, most prominently the use of an emerald by emperor Nero as mentioned by Pliny the Elder.
• Greek fire: Greek fire was an incendiary weapon used by the Eastern Roman (Byzantine) Empire that was first developed c. 672. The Byzantines typically used it in naval battles to great effect, as it could continue burning while floating on water.
• Grenade: Grenades appeared not long after the reign of Leo III (717–741), when Byzantine soldiers learned that Greek fire could not only be projected by flamethrowers, but also be thrown in stone and ceramic jars. Larger containers were hurled by catapults or trebuchets at the enemy, either ignited before release or set alight by fire arrows after impact. Grenades were later adopted for use by Muslim armies: Vessels of the characteristic spheroconical shape which many authors identify as grenade shells were found over much of the Islamic world.
• Gyro: Greek dish made from meat cooked on a vertical rotisserie. Like shawarma and al pastor meat, it is derived from the lamb-based doner kebab.

H

• Hand trebuchet: The hand-trebuchet (cheiromangana) was a staff sling mounted on a pole using a lever mechanism to propel projectiles. Basically a portable trebuchet which could be operated by a single man, it was advocated by emperor Nikephoros II Phokas around 965 to disrupt enemy formations in the open field. It was also mentioned in the Taktika of general Nikephoros Ouranos (ca. 1000), and listed in the Anonymus De obsidione toleranda as a form of artillery.
• Headband: The beginning of headbands was no later than around 475 BC to 330 BC, with the ancient Greeks, who wore hair wreaths.
• Helepolis: Greek siege tower.

• Himation: A himation was a type of clothing, a mantle or wrap worn by ancient Greek men and women from the Archaic through the Hellenistic periods.
• Historiography: The earliest chronologies date back to Mesopotamia and ancient Egypt, in the form of chronicles and annals. By contrast, the term "historiography" is taken to refer to written history recorded in a narrative format for the purpose of informing future generations about events. In this limited sense, "history" begins with the early historiography of Classical Antiquity, in about the 5th century BCE, with Herodotus, the father of history.
• Hydrometer: The hydrometer dates to Archimedes who used its principles to find the density of various liquids.

I

• Ionic order: The Ionic order is one of the three orders of ancient Greek architecture.

• Laïko: Greek music genre composed in Greek language in accordance with the tradition of the Greek people.
• Lead sheathing: To protect a ship's hull from boring creatures. See Kyrenia ship.
• Lever: First described about 260 BC by the ancient Greek mathematician Archimedes. Although used in prehistoric times, they were first put to practical use for more developed technologies in Ancient Greece.
• Libor: The London Inter-bank Offered Rate interest rate benchmark was devised by Greek banker Minos Zombanakis.
• Lighthouse: According to Homeric legend, Palamidis of Nafplio invented the first lighthouse, although they are certainly attested with the Lighthouse of Alexandria (designed and constructed by Sostratus of Cnidus) and the Colossus of Rhodes. However, Themistocles had earlier established a lighthouse at the harbor of Piraeus connected to Athens in the 5th century BC, essentially a small stone column with a fire beacon.

M

• Marathon: The name Marathon comes from the legend of Philippides (or Pheidippides), the Greek messenger. The legend states that, while he was taking part in the battle of Marathon, he witnessed a Persian vessel changing its course towards Athens as the battle was near a victorious end for the Greek army. He interpreted this as an attempt by the defeated Persians to rush into the Greek capital and claim a false victory in the Battle of Marathon, which took place in August or September, 490 BC, hence claiming their authority over Greek land. It is said that he ran the entire distance without stopping, discarding his weapons and even clothes to lose as much weight as possible, and burst into the assembly, exclaiming νενικήκαμεν (nenikēkamen, "we have won!"), before collapsing and dying. The account of the run from Marathon to Athens first appears in Plutarch's On the Glory of Athens in the 1st century AD, which quotes from Heraclides Ponticus's lost work, giving the runner's name as either Thersipus of Erchius or Eucles.
• Marine biology: The study of marine biology dates back to Aristotle, who made many observations of life in the sea around Lesbos, laying the foundation for many future discoveries.
• Mathematical mechanics: Archytas is believed to be the founder of mathematical mechanics.
• Metaxa: Metaxa is a Greek spirit invented by Spyros Metaxas in 1888. It is exported to over 65 countries and it is among the 100 strongest spirit brands worldwide.
• Mini: This distinctive two-door car was designed for the British Motor Corporation by Greek engineer Sir Alec Issigonis. His grandfather Demosthenis migrated to Smyrna from Paros in Greece in the 1830s and through the work he did for the British-built Smyrna-Aydın Railway.
• Morphology: Concept of form in biology, opposed to function, dates back to Aristotle.
• Musical theatre: The antecedents of musical theatre in Europe can be traced back to the theatre of ancient Greece, where music and dance were included in stage comedies and tragedies during the 5th century BCE.

N

• Non-stick pans: Scientific research reveals that the ancient Mycenaean’s, more than 3,000 years ago used portable grilling trays for making souvlaki and non-stick pans for baking bread.

O

• Odometer: Odometer, a device used in the late Hellenistic time and by Romans for indicating the distance travelled by a vehicle. It was invented sometime in the 3rd century BC. Some historians attribute it to Archimedes, others to Heron of Alexandria. It helped revolutionize the building of roads and travelling by them by accurately measuring distance and being able to carefully illustrate this with a milestone.
• Optical telegraph: In the 9th century, during the Arab–Byzantine wars, the Byzantine Empire used a system of beacons to transmit messages from the border with the Abbasid Caliphate across Asia Minor to the Byzantine capital, Constantinople.The main line of beacons stretched over some 450 miles (720 km). In the open spaces of central Asia Minor, the stations were placed over 60 miles (97 km) apart, while in Bithynia, with its more broken terrain, the intervals were reduced to ca. 35 miles (56 km). Based on modern experiments, a message could be transmitted the entire length of the line within an hour. The system was reportedly devised in the reign of Emperor Theophilos (ruled 829–842) by Leo the Mathematician, and functioned through two identical water clocks placed at the two terminal stations, Loulon and the Lighthouse. Different messages were assigned to each of twelve hours, so that the lighting of a bonfire on the first beacon on a particular hour signalled a specific event and was transmitted down the line to Constantinople.
• Olympic Games: The ancient Olympic Games (Ὀλυμπιακοὶ ἀγῶνες; Latin: Olympia, neuter plural: "the Olympics") were a series of athletic competitions among representatives of city-states and one of the Panhellenic Games of Ancient Greece.

P

• Pan flute: In Greek mythology, Syrinx (Σύριγξ) was a forest Nymph. In her attempt to escape the affection of god Pan (a creature half goat and half man), she was transformed into a water-reed or calamos (cane-reed). Then, Pan cut several reeds, placed them in parallel one next to the other, and bound them together to make a melodic musical instrument. Ancient Greeks called this instrument Syrinx, in honour of the Muse, and Pandean, or Pan-pipes and Pan-flute, after Pan.
• Pankration: The mainstream academic view has been that pankration developed in the archaic Greek society of the 7th century BC, whereby, as the need for expression in violent sport increased, pankration filled a niche of "total contest" that neither boxing nor wrestling could. However, some evidence suggests that pankration, in both its sporting form and its combative form, may have been practiced in Greece already from the second millennium BC.
• Paleontology: The ancient Greek philosopher Xenophanes concluded from fossil sea shells that some areas of land were once under water.
• Pap smear: he test was invented by and named after the Greek doctor Georgios Papanikolaou, who started his research in 1923.
• Pap test: A test for cervical cancer developed by the Greek physician George Papanikolaou in 1923.
• Pediment: Architectural element found particularly in Classical, Neoclassical and Baroque architecture, and its derivatives, consisting of a gable, usually of a triangular shape, placed above the horizontal structure of the lintel, or entablature, if supported by columns. The tympanum, the triangular area within the pediment, is often decorated with relief sculpture. A pediment is sometimes the top element of a portico. For symmetric designs, it provides a centre point and is often used to add grandness to entrances.
• Pentathlon: The first documented pentathlon occurred in 708 BC in Ancient Greece at the Ancient Olympic Games, and was also held at the other Panhellenic Games.
• Peplos: A peplos is a body-length garment established as typical attire for women in ancient Greece by 500 BC.
• Physical therapy: Physicians like Hippocrates and later Galen are believed to have been the first practitioners of physical therapy, advocating massage, manual therapy techniques and hydrotherapy to treat people in 460 BC.
• Physiology: The study of human physiology as a medical field originates in classical Greece, at the time of Hippocrates.
• Pipe organ: The Greek engineer Ctesibius of Alexandria is credited with inventing the organ in the 3rd century BC.
• Planetary science: The history of planetary science may be said to have begun with the Ancient Greek philosopher Democritus.
• Plumbing: Plumbing has been a practice since the neolithic age however the ancient Minoans of Crete, were the first civilizations to have underground pipes, carrying water.
• Pointed arch bridge: The earliest known bridge resting on a pointed arch is the 5th or 6th century AD Karamagara Bridge in Cappadocia. Its single arch of 17 m spanned an affluent of the Euphrates. A Greek inscription, citing from the Bible, runs along one side of its arch rib. The structure is today submerged by the Keban Reservoir.
• Political science: As a social political science, contemporary political science started to take shape in the latter half of the 19th century. At that time it began to separate itself from political philosophy, which traces its roots back to the works of Aristotle and Plato.

R

• Railway: The 6 to 8.5 km long Diolkos represented a rudimentary form of railway.
• Rebetiko: term used today to designate originally disparate kinds of urban Greek music which have come to be grouped together since the so-called rebetika revival, which started in the 1960s and developed further from the early 1970s onwards.

S

• Sakia gear: First appeared in 2nd-century BC Hellenistic Egypt, where pictorial evidence already showed it fully developed.
• Screw press: The screw press, probably invented in Greece in the 1st or 2nd century BC, has been used since the days of the Roman Empire for pressing clothes.
• Shower: The Ancient Greeks were the first known people to have showers, which were connected to their lead pipe plumbing system. A shower room for female athletes with plumbed-in water is depicted on an Athenian vase. A whole complex of shower-baths was also found in a 2nd-century BC gymnasium at Pergamum.
• Sociology: The sociological reasoning may be traced back at least as far as the ancient Greeks. Social analysis has origins in the common stock of Western knowledge and philosophy and ancient Greek philosophers Socrates, Plato, and Aristotle.
• Souvlaki: Excavations in Santorini, Greece, unearthed sets of stone cooking supports used before the 17th century BC. In the supports there are pairs of indentations that were likely used for holding skewers. The line of holes in the base allowed the coals to be supplied with oxygen.
• Steam engine: Archimedes invented the first steam-powered device however, Hero of Alexandria designed the Aeolipile. The aeolipile is a simple bladeless radial steam turbine which spins when the central water container is heated. Torque is produced by steam jets exiting the turbine, much like a tip jet. Hero of Alexandria first described the aeolipile in the 1st century AD and many sources give him the credit for its invention.
• Steam-powered device: Archimedes invented the first steam-powered device with the Steam cannon.
• Spiral staircase: The earliest spiral staircases appear in Temple A in Selinunte, Sicily, to both sides of the cella. The temple was constructed around 480–470 BC.
• Stoa: In ancient Greek architecture, is a covered walkway or portico, commonly for public use. Early stoas were open at the entrance with columns, usually of the Doric order, lining the side of the building; they created a safe, enveloping, protective atmosphere.
• Streets: Example: The Porta Rosa (4th–3rd century BC) was the main street of Elea (Italy) and connected the northern quarter to the southern quarter. The street is 5 meters wide. At its steepest, it has an inclination of 18%. It is paved with limestone blocks, grinders cut in square blocks, and on one side a small gutter for the drainage of rain water. The building is dated during the time of the reorganization of the city during Hellenistic age.
• Surgical instruments: Ancient medical treatises including the Hippocratic corpus describe surgical tools used for examining injuries, making small incisions, removing arrowheads, gynecological examinations, abortions, tooth extraction, and removing bladder stones.
• Surveying tools: Various records relating to mentions of surveying tools have been discovered, mostly in Alexandrian sources, these greatly helped the development of the precision of Roman aqueducts.
• Syringe: The ancient Greeks and Romans knew injection as a method of medicinal delivery from observations of snakebites and poisoned weapons.

T

• Theatre: Theatre, in its modern sense, involving the performance of pre-written tragic, dramatic and comedic plays for an audience, first originated in Classical Athens in the 6th century BC.
• Three-masted ship: First recorded for Syracusia as well as other Syracusan (merchant) ships under Hiero II of Syracuse.
• Thesaurus: In antiquity, Philo of Byblos authored the first text that could now be called a thesaurus.
• Torsion siege engine: Preceding the development of torsion siege engines were tension siege engines that had existed since at least the beginning of the 4th century BC, most notably the gastraphetes in Heron of Alexandria's Belopoeica that was probably invented in Syracuse by Dionysius the Elder. Simple Torsion devices could have been developed earlier, the first extant evidence of a torsion siege engine comes from the Chalcotheca, the arsenal on the Acropolis in Athens, and dates to c. 338 – 326 BC. It lists the building's inventory that included torsion catapults and its components such as hair springs, catapult bases, and bolts.
• Toxicology: Dioscorides, a Greek physician in the court of the Roman emperor Nero, made the first attempt to classify plants according to their toxic and therapeutic effect.
• Truss roof: See List of Greco-Roman roofs.
• Tsipouro: The first production of tsipouro was the work of Greek Orthodox monks in the 14th century on Mount Athos in Macedonia, Greece.
• Tzatziki: Greek dip, soup, or sauce found in the cuisines of Southeast Europe and the Middle East. It is made of salted strained yogurt or diluted yogurt mixed with cucumbers, garlic, salt, olive oil, sometimes with vinegar or lemon juice, and herbs such as dill, mint, parsley and thyme.

V

• Vending machine: The first vending machine was described by Heron of Alexandria. His machine accepted a coin and then dispensed a fixed amount of holy water. When the coin was deposited, it fell upon a pan attached to a lever. The lever opened up a valve, which let some water flow out. The pan continued to tilt with the weight of the coin until it fell off, at which point a counter-weight would snap the lever back up and turn off the valve.

W

• Watermill: The use of water power was pioneered by the Greeks: The earliest mention of a water mill in history occurs in Philo's Pneumatics, previously been regarded as a later Arabic interpolation, but according to recent research to be of authentic Greek origin.
• Water wheel: First described by Philo of Byzantium (c. 280–220 BC). The ancient Greeks invented the waterwheel and were, along with the Romans, the first to use it in nearly all of the forms and functions described above, including its application for watermilling. The technological breakthrough occurred in the technically advanced and scientifically minded Hellenistic period between the 3rd and 1st century BC
• Wheelbarrow: The history of the wheelbarrow began in Greece circa 406 BC. However there are no records that indicate who actually made it.
• Winch: The earliest literary reference to a winch can be found in the account of Herodotus of Halicarnassus on the Persian Wars (Histories 7.36), where he describes how wooden winches were used to tighten the cables for a pontoon bridge across the Hellespont in 480 BC. Winches may have been employed even earlier in Assyria, though. By the 4th century BC, winch and pulley hoists were regarded by Aristotle as common for architectural use (Mech. 18; 853b10-13).
• Windlass: The Greek scientist Archimedes was the inventor of the windlass.
• Wind-powered machine: Hero of Alexandria (Heron) in first-century Roman Egypt described what appears to be a wind-driven wheel to power a machine. His description of a wind-powered organ is not a practical windmill, but was either an early wind-powered toy, or a design concept for a wind-powered machine.
• Wind vane: The Tower of the Winds on the Roman agora in Athens featured atop a wind vane in the form of a bronze Triton holding a rod in his outstretched hand rotating to the wind blowing. Below, its frieze was adorned with the eight wind deities. The 8 m high structure also featured sundials and a water clock inside dates from around 50 BC.

Z

• Zoology: Although the concept of zoology as a single coherent field arose much later, the zoological sciences emerged from natural history reaching back to the biological works of Aristotle and Galen in the ancient Greco-Roman world.

Discoveries made by Greeks

Astronomy

• Equinox: Thales discovered the equinox.
• Heliocentrism – The notion that the Earth and planets revolves around the Sun was first proposed by Aristarchus of Samos in the 3rd century BC.
• Solstice: Thales discovered the solstice.

Geography

• Latitude: The invention of a geographic coordinate system is generally credited to Eratosthenes of Cyrene, who composed his now-lost Geography at the Library of Alexandria in the 3rd century BC.
• Longitude: The invention of a geographic coordinate system is generally credited to Eratosthenes of Cyrene, who composed his now-lost Geography at the Library of Alexandria in the 3rd century BC.

Mathematics

• Mathematical deduction – Thales of Miletus, considered by Aristotle to be the first Greek philosopher, is thought to be the first individual to apply deductive reasoning to produce mathematical proofs, particularly in the field of geometry
• Thales' theorem – One of the most basic theorems of geometry, stating that whenever an angle is drawn from two ends of the diameter of a circle to any third point on its circumference, the angle formed at the third point is always a perfect right angle. The phenomenon was known empirically to the Indians and Babylonians but was first proved in the 6th century BC by Thales of Miletus, making him the first known individual to whom a mathematical discovery has been attributed.
• Intercept theorem – Also attributed to Thales is the fundamental theorem of geometry that states that the ratios of corresponding sides of similar triangles (i.e. triangles formed from the intersection of two common lines with two different parallel lines) are equal. Thales is said to have used his theorem to determine the height of pyramids by measuring the lengths of their shadows.
• Conic sections – First developed by Menaechmus in the 4th century BC, but the most significant contribution is by Apollonius of Perga in the 3rd century BC.
• Method of exhaustion – Formalized by Eudoxus of Cnidus in the early 4th century BC, used by Archimedes to calculate the value of pi and the area under a curve.
• Mathematical proof – The mathematical proof was a product of Greek mathematics, evolving gradually to reach the method still used today in Euclid's Elements around 300 BC.
• Sieve of Eratosthenes – Developed by Eratosthenes in the 3rd century BC to calculate prime numbers.

Philosophy

• Socratic method – A form of cooperative argumentative dialogue between individuals, based on asking and answering questions to stimulate critical thinking and to draw out ideas and underlying presuppositions. It is named after the Classical Greek philosopher Socrates and is introduced by him in Plato's Theaetetus as midwifery (maieutics) because it is employed to bring out definitions implicit in the interlocutors' beliefs, or to help them further their understanding.
