Hanno, Messana garrison commander
Hanno was a Carthaginian general prominent in the events leading to the start of the First Punic War. In 265 BC the Mamertines who were occupying Messana were being threatened by Hiero II of Syracuse, they sent appeals for assistance to Rome and Carthage. The Carthaginians were first to respond dispatching a small force commanded by Hanno to occupy the citadel of Messana and patrol the strait of Messina; the Roman consul Appius Claudius Caudex desiring personal glory persuaded the Roman People with promises of profit to vote in favour of intervening in Messana. Gaius Claudius, a military tribune was sent in advance by the consul Appius Claudius Caudex with a few ships to Rhegium, a city allied to the Romans on the opposite side of the strait on the Italian mainland. G. Claudius commenced negotiations with Hanno but negotiations must have broken down and Gaius unsuccessfully tried to force passage across the strait in the process losing some triremes to the Carthaginians who were skillful sailors.
Hanno understanding the gravity of the situation and not wanting to be blamed for starting a war with the Romans, as a gesture returned the captured vessels to the Romans and urged them to opt for peace. Gaius Claudius, it would seem, tried again to cross the strait to Messana; the Mamertines urged Hanno to descend from the parley with the Romans. Hanno reluctantly agreed but again the talks failed; the Romans imprisoned him. Hanno was thus compelled to withdraw the Carthaginian garrison from Messana; these events triggered the beginning of the First Punic War. The Carthaginians subsequently crucified Hanno for what was regarded as cowardice and lack of judgement in leaving the citadel of Messana.

Rome is the capital city and a special comune of Italy. Rome serves as the capital of the Lazio region. With 2,872,800 residents in 1,285 km2, it is the country's most populated comune, it is the fourth most populous city in the European Union by population within city limits. It is the centre of the Metropolitan City of Rome, which has a population of 4,355,725 residents, thus making it the most populous metropolitan city in Italy. Rome is located in the central-western portion of the Italian Peninsula, within Lazio, along the shores of the Tiber; the Vatican City is an independent country inside the city boundaries of Rome, the only existing example of a country within a city: for this reason Rome has been defined as capital of two states. Rome's history spans 28 centuries. While Roman mythology dates the founding of Rome at around 753 BC, the site has been inhabited for much longer, making it one of the oldest continuously occupied sites in Europe; the city's early population originated from a mix of Latins and Sabines.
The city successively became the capital of the Roman Kingdom, the Roman Republic and the Roman Empire, is regarded by some as the first metropolis. It was first called The Eternal City by the Roman poet Tibullus in the 1st century BC, the expression was taken up by Ovid and Livy. Rome is called the "Caput Mundi". After the fall of the Western Empire, which marked the beginning of the Middle Ages, Rome fell under the political control of the Papacy, in the 8th century it became the capital of the Papal States, which lasted until 1870. Beginning with the Renaissance all the popes since Nicholas V pursued over four hundred years a coherent architectural and urban programme aimed at making the city the artistic and cultural centre of the world. In this way, Rome became first one of the major centres of the Italian Renaissance, the birthplace of both the Baroque style and Neoclassicism. Famous artists, painters and architects made Rome the centre of their activity, creating masterpieces throughout the city.
In 1871, Rome became the capital of the Kingdom of Italy, which, in 1946, became the Italian Republic. Rome has the status of a global city. In 2016, Rome ranked as the 14th-most-visited city in the world, 3rd most visited in the European Union, the most popular tourist attraction in Italy, its historic centre is listed by UNESCO as a World Heritage Site. The famous Vatican Museums are among the world's most visited museums while the Colosseum was the most popular tourist attraction in world with 7.4 million visitors in 2018. Host city for the 1960 Summer Olympics, Rome is the seat of several specialized agencies of the United Nations, such as the Food and Agriculture Organization, the World Food Programme and the International Fund for Agricultural Development; the city hosts the Secretariat of the Parliamentary Assembly of the Union for the Mediterranean as well as the headquarters of many international business companies such as Eni, Enel, TIM, Leonardo S.p. A. and national and international banks such as Unicredit and BNL.
Its business district, called EUR, is the base of many companies involved in the oil industry, the pharmaceutical industry, financial services. Rome is an important fashion and design centre thanks to renowned international brands centered in the city. Rome's Cinecittà Studios have been the set of many Academy Award–winning movies. According to the founding myth of the city by the Ancient Romans themselves, the long-held tradition of the origin of the name Roma is believed to have come from the city's founder and first king, Romulus. However, it is a possibility that the name Romulus was derived from Rome itself; as early as the 4th century, there have been alternative theories proposed on the origin of the name Roma. Several hypotheses have been advanced focusing on its linguistic roots which however remain uncertain: from Rumon or Rumen, archaic name of the Tiber, which in turn has the same root as the Greek verb ῥέω and the Latin verb ruo, which both mean "flow". There is archaeological evidence of human occupation of the Rome area from 14,000 years ago, but the dense layer of much younger debris obscures Palaeolithic and Neolithic sites.
Evidence of stone tools and stone weapons attest to about 10,000 years of human presence. Several excavations support the view that Rome grew from pastoral settlements on the Palatine Hill built above the area of the future Roman Forum. Between the end of the bronze age and the beginning of the Iron age, each hill between the sea and the Capitol was topped by a village. However, none of them had yet an urban quality. Nowadays, there is a wide consensus that the city developed through the aggregation of several villages around the largest one, placed above the Palatine; this aggregation was facilitated by the increase of agricultural productivity above the subsistence level, which allowed the establishment of secondary and tertiary activities. These in turn boosted the development of trade with the Greek colonies of southern Italy; these developments, which according to archaeological ev
First Punic War
The First Punic War was the first of three wars fought between Ancient Carthage and the Roman Republic, the two great powers of the Western Mediterranean. For 23 years, in the longest continuous conflict and greatest naval war of antiquity, the two powers struggled for supremacy on the Mediterranean island of Sicily and its surrounding waters, in North Africa; the war began in 264 BC with the Roman conquest of the Carthaginian-controlled city of Messina in Sicily, granting Rome a military foothold on the island. The Romans built up a navy to challenge Carthage, the greatest naval power in the Mediterranean, for control over the waters around Sicily. In naval battles and storms, 700 Roman and 500 Carthaginian quinqueremes were lost, along with hundreds of thousands of lives. Command of the sea was lost by both sides repeatedly. A Roman invasion of Carthaginian Africa was destroyed in battle at the Bagradas and the Roman consul Marcus Atilius Regulus was captured by the Carthaginians in 255. In 23 years, the Romans conquered Sicily and drove the Carthaginians to the west end of the island.
After both sides had been brought to a state of near exhaustion, the Romans mobilized their citizenry's private wealth and created a new fleet under consul Gaius Lutatius Catulus. The Carthaginian fleet was destroyed at the Aegates Islands in 241, forcing the cut-off Carthaginian troops on Sicily to give up. A peace treaty was signed in which Carthage was made to pay a heavy indemnity and Rome ejected Carthage from Sicily, annexing the island as a Roman province; the war was followed by a failed revolt against the Carthaginian Empire. The Romans exploited Carthage's weakness to seize the Carthaginian possessions of Sardinia and Corsica in violation of the peace treaty; the unresolved strategic competition between Rome and Carthage would lead to the eruption of the Second Punic War in 218 BC. The series of wars between Rome and Carthage took the name "Punic" from the Latin adjective for Carthaginian, Punicus; this refers to the Carthaginian heritage as Phoenician colonists. A Carthaginian name for the conflicts does not survive in any records.
Rome had emerged as the leading city-state in the Italian Peninsula, a wealthy, expansionist republic with a successful citizen army. Over the past one hundred years, Rome had come into conflict, defeated rivals on the Italian peninsula incorporated them into the Roman political world. First, the Latin League was forcibly dissolved during the Latin War the power of the Samnites was broken during the three prolonged Samnite wars, the Greek cities of Magna Graecia submitted to Roman power at the conclusion of the Pyrrhic War. By the beginning of the First Punic War, the Romans had secured the whole of the Italian peninsula, except Gallia Cisalpina in the Po Valley. Carthage was a republic that dominated the political and economic affairs of the western Mediterranean Sea on the North African coasts and islands, above all, due to its navy, it originated as a Phoenician colony near modern Tunis. Carthage had become a wealthy centre for trade networks extending from Gadir along the coasts of southern Iberia and North Africa, across the Balearic Islands, Corsica and the western half of Sicily, to the ports of the eastern Mediterranean, including Tyre, its mother city, on the shores of the Levant.
At the height of power, just before the First Punic War, Carthage was hostile to foreign ships in the western Mediterranean. North African peoples, such as the Berbers, in the area around Carthage were loosely associated with Carthage. In the midst of the First Punic War, some tribes rebelled against Carthage, opening a second front while the Carthaginians battled the Romans in Sicily. Greek colonists were a major presence in the western Mediterranean, following centuries of colonial settlement and conflicts with Rome over Magna Graecia and with Carthage over places such as Sicily; the rich, strategically influential, well-fortified Greek colony of Syracuse was politically independent of Rome and Carthage. Hostilities of the First Punic War began with developments involving the Romans and Greek colonists in Sicily and southern Italy. In 288 BC, the Mamertines, a group of Italian mercenaries hired by Agathocles of Syracuse, occupied the city of Messana in the north-eastern tip of Sicily, killing all the men and taking the women as their wives.
At the same time, a group of Roman troops made up of Campanian "citizens without the vote" revolted and seized control of Rhegium, lying across the Straits of Messina on the mainland of Italy. In 270 BC, the Romans regained control of Rhegium and punished the survivors of the revolt. In Sicily, the Mamertines ravaged the countryside and collided with the expanding regional empire of the independent city of Syracuse. Hiero II, tyrant of Syracuse, defeated the Mamertines near Mylae on the Longanus River. Following their defeat, the Mamertines appealed to both Carthage for assistance; the Carthaginians acted first, approached Hiero to take no further action and convinced the Mamertines to accept a Carthaginian garrison in Messana. Either unhappy with the prospect of a Carthaginian garrison or convinced that the recent alliance between Rome and Carthage against Pyrrhus reflected cordial relations between the two, the Mamertines, hoping for more reliable protection, petitioned Rome for an alliance.
However, the rivalry between Rome and Carthage had grown since the war with Pyrrhus and that alliance was no longer feasible. According to the historian Polybius, considerable debate took place in Rome on the questio
Moses was a prophet according to the teachings of the Abrahamic religions. Scholarly consensus sees Moses as a legendary figure. According to the Hebrew Bible, he was adopted by an Egyptian princess, in life became the leader of the Israelites and lawgiver, to whom the authorship of the Torah, or acquisition of the Torah from Heaven is traditionally attributed. Called Moshe Rabbenu in Hebrew, he is the most important prophet in Judaism, he is an important prophet in Christianity, the Bahá'í Faith, a number of other Abrahamic religions. According to the Book of Exodus, Moses was born in a time when his people, the Israelites, an enslaved minority, were increasing in numbers and the Egyptian Pharaoh was worried that they might ally themselves with Egypt's enemies. Moses' Hebrew mother, secretly hid him when the Pharaoh ordered all newborn Hebrew boys to be killed in order to reduce the population of the Israelites. Through the Pharaoh's daughter, the child was adopted as a foundling from the Nile river and grew up with the Egyptian royal family.
After killing an Egyptian slavemaster, Moses fled across the Red Sea to Midian, where he encountered The Angel of the Lord, speaking to him from within a burning bush on Mount Horeb. God sent Moses back to Egypt to demand the release of the Israelites from slavery. Moses said that he could not speak eloquently, so God allowed Aaron, his brother, to become his spokesperson. After the Ten Plagues, Moses led the Exodus of the Israelites out of Egypt and across the Red Sea, after which they based themselves at Mount Sinai, where Moses received the Ten Commandments. After 40 years of wandering in the desert, Moses died within sight of the Promised Land on Mount Nebo. Jerome gives 1592 BCE, James Ussher 1571 BCE as Moses' birth year. In the Book of Deuteronomy, Moses was called "the man of God". Several etymologies have been proposed. An Egyptian root msy, "child of", has been considered as a possible etymology, arguably an abbreviation of a theophoric name, as for example in Egyptian names like Thutmoses and Ramesses, with the god's name omitted.
Abraham Yahuda, based on the spelling given in the Tanakh, argues that it combines "water" or "seed" and "pond, expanse of water", thus yielding the sense of "child of the Nile". The Biblical account of Moses' birth provides him with a folk etymology to explain the ostensible meaning of his name, he is said to have received it from the Pharaoh's daughter: "he became her son. She named him Moses, saying,'I drew him out of the water.'" This explanation links it to a verb mashah, meaning "to draw out", which makes the Pharaoh's daughter's declaration a play on words. The princess made a grammatical mistake, prophetic of his future role in legend, as someone who will "draw the people of Israel out of Egypt through the waters of the Red Sea."The Hebrew etymology in the Biblical story may reflect an attempt to cancel out traces of Moses' Egyptian origins. The Egyptian character of his name was recognized as such by ancient Jewish writers like Philo of Alexandria and Josephus. Philo linked Mōēsēs to the Egyptian word for water, while Josephus, in his Antiquities of the Jews, claimed that the second element, -esês, meant'those who are saved'.
The problem of how an Egyptian princess, known to Josephus as Thermutis and in Jewish tradition as Bithiah, could have known Hebrew puzzled medieval Jewish commentators like Abraham ibn Ezra and Hezekiah ben Manoah. Hezekiah suggested she either took a tip from Jochebed; the Israelites had settled in the Land of Goshen in the time of Joseph and Jacob, but a new pharaoh arose who oppressed the children of Israel. At this time Moses was born to his father Amram, son of Kehath the Levite, who entered Egypt with Jacob's household. Moses had one older sister and one older brother, Aaron; the Pharaoh had commanded that all male Hebrew children born would be drowned in the river Nile, but Moses' mother placed him in an ark and concealed the ark in the bulrushes by the riverbank, where the baby was discovered and adopted by Pharaoh's daughter, raised as an Egyptian. One day after Moses had reached adulthood he killed an Egyptian, beating a Hebrew. Moses, in order to escape the Pharaoh's death penalty, fled to Midian.
There, on Mount Horeb, God appeared to Moses as a burning bush, revealed to Moses his name YHWH and commanded him to return to Egypt and bring his chosen people out of bondage and into the Promised Land. During the journey, God tried to kill Moses because he had not circumcised his son, but Zipporah saved his life. Moses returned to carry out God's command, but God caused the Pharaoh to refuse, only after God had subjected Egypt to ten plagues did the Pharaoh relent. Moses led the Israelites to the border of Egypt, but there God hardened the Pharaoh's heart once more, so that he could destroy the Pharaoh and his army at the Red Sea Crossing as a sign of his power to Israel and the nations. After defeating the Amalekites in Rephidim, Moses led the Israelites to biblical Mount Sinai, where he was given the Ten Commandments from God, written on stone tablets. However, since Moses remained a long time on the mountain, some of the people feared that he might be dead, so they made a statue of a golden calf and worshiped it, thus disobeying and angering God and Moses.
Moses, out of anger, bro
A votive crown is a votive offering in the form of a crown in precious metals and adorned with jewels. In the Early Middle Ages, they are of a special form, designed to be suspended by chains at an altar, shrine or image. Examples are more typical crowns in the style of the period, either designed to be placed on the head of a statue, or re-used in this way after donation. There were pagan votive crowns in the ancient world, although these are known only from literary references. Vitruvius records that when Hiero II of Syracuse suspected his goldsmith of cheating him over the making of a votive crown for a statue in a temple, for which he had supplied the gold to be used, he asked Archimedes to devise a test; this led Archimedes to his famous eureka moment, after he realized he could test the crown by comparing its displacement of water to that of the same weight of pure gold. From other references, it seems that in classical times not just statues of the gods, but living rulers were presented with crowns in the hope of a favourable response to a request.
The largest number of surviving examples of the Christian Early Medieval suspended type come from 7th century Visigothic Hispania the Treasure of Guarrazar, from near Toledo, which includes no fewer than twenty-six examples in gold hidden as the Muslim invasion drew near. These were excavated in 1859, are now divided between the National Archaeological Museum of Spain in Madrid and the Musée de Cluny in Paris; however the type was Roman or Byzantine, adopted across Europe. These could not be worn, as they were too small and very had pendilia, or dangling ornaments on chains hanging from the main crown with jewels and formed into letters which spelled a word or phrase. In the example above, the letters on the pendilia spell "RECCESVINTHVS REX OFFERET", or "King Recceswinth offered this"; these royal donations signified the submission of the monarchy to God. Such objects were influenced by the thirty suspended gold crowns placed round the main altar of Hagia Sophia by Justinian, now lost, although the Christian practice is at least as old as the 4th century.
The main body of suspended crowns is flat around the top as well as the bottom rim. Such crowns were found across Christian Europe in this period; the Iron Crown of Lombardy was originally made as a votive crown, although it was used for the coronation of monarchs including Napoleon I. Another gold crown was a source of contention in Constantinople. Instead, he had it suspended by chains over the main altar of Hagia Sophia, upsetting the two ladies, it hung there until Emperor Leo IV coveted it and took it for his own use. In a suspiciously neat story, the crown was richly decorated with carbuncles, Leo, an iconoclast, soon after died of an outbreak of carbuncles, allowing the church to draw the obvious conclusion. Another Byzantine votive crown, given by Leo VI is now in the Treasury of San Marco, is decorated with cloisonné enamels. In England, a medieval source says that King Canute gave a, or "his", crown to be placed on or over the head of the rood, or large crucifix, in Winchester Cathedral.
The Anglo-Saxon Chronicle records that Hereward the Wake's men looted a solid gold crown from the head of the rood on the main altar of Peterborough Cathedral in 1070. The Romanesque period saw the height of crowned images of Christ, shown wearing a crown on the cross in wood and metal figures, manuscript illuminations, the introduction of crowned images of the Virgin Mary in the West, as the concept of Mary as Queen of Heaven became prominent. A small late medieval crown now in the Treasury of Aachen Cathedral was made for the famously lavish wedding celebrations in 1468 of Margaret of York, Duchess of Burgundy, sister of Edward IV of England, placed on a statue of the Virgin Mary as a votive offering, it was designed to be worn on top of an elaborate headress and hairstyle, or on a hennin, is much smaller than a conventional crown for wearing directly on the head. This is now a rare example of a medieval votive crown. A few years in 1487, the crown, used by the pretender Lambert Simnel was given to a statue of the Virgin in Dublin.
Crowns designed for statues became elaborate in the Baroque period, in the Spanish world. Statues of the Virgin Mary and the Infant Jesus, of the Infant Jesus of Prague type, are among those most crowned; the Crown of the Andes is a votive crown from Colombia in gold with 450 emeralds made between the late 16th and 18th centuries originally as an offering in thanks for the city of Popayán being spared from a plague. It is now in private hands in the US. Votive crowns have continued to be produced in Catholic countries
Archimedes of Syracuse was a Greek mathematician, engineer and astronomer. Although few details of his life are known, he is regarded as one of the leading scientists in classical antiquity. Considered the greatest mathematician of antiquity and one of the greatest of all time, Archimedes anticipated modern calculus and analysis by applying concepts of infinitesimals and the method of exhaustion to derive and rigorously prove a range of geometrical theorems, including the area of a circle, the surface area and volume of a sphere, the area under a parabola. Other mathematical achievements include deriving an accurate approximation of pi, defining and investigating the spiral bearing his name, creating a system using exponentiation for expressing large numbers, he was one of the first to apply mathematics to physical phenomena, founding hydrostatics and statics, including an explanation of the principle of the lever. He is credited with designing innovative machines, such as his screw pump, compound pulleys, defensive war machines to protect his native Syracuse from invasion.
Archimedes died during the Siege of Syracuse when he was killed by a Roman soldier despite orders that he should not be harmed. Cicero describes visiting the tomb of Archimedes, surmounted by a sphere and a cylinder, which Archimedes had requested be placed on his tomb to represent his mathematical discoveries. Unlike his inventions, the mathematical writings of Archimedes were little known in antiquity. Mathematicians from Alexandria read and quoted him, but the first comprehensive compilation was not made until c. 530 AD by Isidore of Miletus in Byzantine Constantinople, while commentaries on the works of Archimedes written by Eutocius in the sixth century AD opened them to wider readership for the first time. The few copies of Archimedes' written work that survived through the Middle Ages were an influential source of ideas for scientists during the Renaissance, while the discovery in 1906 of unknown works by Archimedes in the Archimedes Palimpsest has provided new insights into how he obtained mathematical results.
Archimedes was born c. 287 BC in the seaport city of Syracuse, Sicily, at that time a self-governing colony in Magna Graecia, located along the coast of Southern Italy. The date of birth is based on a statement by the Byzantine Greek historian John Tzetzes that Archimedes lived for 75 years. In The Sand Reckoner, Archimedes gives his father's name as Phidias, an astronomer about whom nothing else is known. Plutarch wrote in his Parallel Lives that Archimedes was related to King Hiero II, the ruler of Syracuse. A biography of Archimedes was written by his friend Heracleides but this work has been lost, leaving the details of his life obscure, it is unknown, for instance, whether he married or had children. During his youth, Archimedes may have studied in Alexandria, where Conon of Samos and Eratosthenes of Cyrene were contemporaries, he referred to Conon of Samos as his friend, while two of his works have introductions addressed to Eratosthenes. Archimedes died c. 212 BC during the Second Punic War, when Roman forces under General Marcus Claudius Marcellus captured the city of Syracuse after a two-year-long siege.
According to the popular account given by Plutarch, Archimedes was contemplating a mathematical diagram when the city was captured. A Roman soldier commanded him to come and meet General Marcellus but he declined, saying that he had to finish working on the problem; the soldier was enraged by this, killed Archimedes with his sword. Plutarch gives a lesser-known account of the death of Archimedes which suggests that he may have been killed while attempting to surrender to a Roman soldier. According to this story, Archimedes was carrying mathematical instruments, was killed because the soldier thought that they were valuable items. General Marcellus was angered by the death of Archimedes, as he considered him a valuable scientific asset and had ordered that he must not be harmed. Marcellus called Archimedes "a geometrical Briareus"; the last words attributed to Archimedes are "Do not disturb my circles", a reference to the circles in the mathematical drawing that he was studying when disturbed by the Roman soldier.
This quote is given in Latin as "Noli turbare circulos meos," but there is no reliable evidence that Archimedes uttered these words and they do not appear in the account given by Plutarch. Valerius Maximus, writing in Memorable Doings and Sayings in the 1st century AD, gives the phrase as "...sed protecto manibus puluere'noli' inquit,'obsecro, istum disturbare'" – "... but protecting the dust with his hands, said'I beg of you, do not disturb this.'" The phrase is given in Katharevousa Greek as "μὴ μου τοὺς κύκλους τάραττε!". The tomb of Archimedes carried a sculpture illustrating his favorite mathematical proof, consisting of a sphere and a cylinder of the same height and diameter. Archimedes had proven that the volume and surface area of the sphere are two thirds that of the cylinder including its bases. In 75 BC, 137 years after his death, the Roman orator Cicero was serving as quaestor in Sicily, he had heard stories about the tomb of Archimedes, but none of the locals were able to give him the location.
He found the tomb near the Agrigentine gate in Syracuse, in a neglected condition and overgrown with bushes. Cicero had the tomb cleaned up, was able to see the carving and read some of the verses, added as an inscription. A tomb discovered in the courtyard of the Hotel Panorama in Syracuse in the early 1960s was claimed to be that of Archimedes, but there was no compelling evidence
Marcus Vitruvius Pollio known as Vitruvius, was a Roman author, civil engineer 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. By his own description Vitruvius served as an artilleryman, the third class of arms in the military offices, he served as a senior officer of artillery in charge of doctores ballistarum and libratores who operated the machines. Little is known about Vitruvius' life. Most inferences about him are extracted from his only surviving work De Architectura, his first name Marcus and his cognomen Pollio are uncertain. Marcus Cetius Faventinus writes of "Vitruvius Polio aliique auctores". An inscription in Verona, which names a Lucius Vitruvius Cordo, an inscription from Thilbilis in North Africa, which names a Marcus Vitruvius Mamurra have been suggested as evidence that Vitruvius and Mamurra were from the same family.
Neither association, however, is borne out by De Architectura, nor by the little, known of Mamurra. Vitruvius was a military engineer, or a praefect architectus armamentarius of the apparitor status group, he is mentioned in Pliny the Elder's table of contents for Naturalis Historia, in the heading for mosaic techniques. Frontinus refers to "Vitruvius the architect" in his late 1st-century work De aquaeductu. Born a free Roman citizen, by his own account, Vitruvius served in the Roman army under Caesar with the otherwise poorly identified Marcus Aurelius, Publius Minidius, Gnaeus Cornelius; these names vary depending on the edition of De architectura. Publius Minidius is written as Publius Numidicus and Publius Numidius, speculated as the same Publius Numisius inscribed on the Roman Theatre at Heraclea; as an army engineer he specialized in the construction of ballista and scorpio artillery war machines for sieges. It is speculated; the locations where he served can be reconstructed from, for example, descriptions of the building methods of various "foreign tribes".
Although he describes places throughout De Architectura, he does not say. His service included north Africa, Hispania and Pontus. To place the role of Vitruvius the military engineer in context, a description of "The Prefect of the camp" or army engineer is quoted here as given by Flavius Vegetius Renatus in The Military Institutions of the Romans: The Prefect of the camp, though inferior in rank to the, had a post of no small importance; the position of the camp, the direction of the entrenchments, the inspection of the tents or huts of the soldiers and the baggage were comprehended in his province. His authority extended over the sick, the physicians who had the care of them, he had the charge of providing carriages and the proper tools for sawing and cutting wood, digging trenches, raising parapets, sinking wells and bringing water into the camp. He had the care of furnishing the troops with wood and straw, as well as the rams, onagri and all the other engines of war under his direction; this post was always conferred on an officer of great skill and long service, and, capable of instructing others in those branches of the profession in which he had distinguished himself.
At various locations described by Vitruvius and sieges occurred. He is the only source for the siege of Larignum in 56 BC. Of the battlegrounds of the Gallic War there are references to: the siege and massacre of the 40,000 residents at Avaricum in 52 BC; the broken siege at Gergovia in 52 BC. The circumvallation and Battle of Alesia in 52 BC, and the siege of Uxellodunum in 51 BC. These are all sieges of large Gallic oppida. Of the sites involved in Caesar's civil war, we find the Siege of Massilia in 49 BC, the Battle of Dyrrhachium of 48 BC, the Battle of Pharsalus in 48 BC, the Battle of Zela of 47 BC and the Battle of Thapsus in 46 BC in Caesar's African campaign. A legion that fits the same sequence of locations is the Legio VI Ferrata, of which ballista would be an auxiliary unit. Known for his writings, Vitruvius was himself an architect. In Roman times architecture was a broader subject than at present including the modern fields of architecture, construction management, construction engineering, chemical engineering, civil engineering, materials engineering, mechanical engineering, military engineering and urban planning.
Frontinus mentions him in connection with the standard sizes of pipes. He is credited as father of architectural acoustics for describing the technique of echeas placement in theaters; the only building, that we know Vitruvius to have worked on is one he tells us about, a basi
