100-467: Vitruvius ( / v ɪ ˈ t r uː v i ə s / vi- TROO -vee-əs , Latin: [wɪˈtruːwi.ʊs] ; c.  80 –70 BC – after c.  15 BC ) was a Roman architect and engineer during the 1st century BC, known for his multi-volume work titled De architectura . As the only treatise on architecture to survive from antiquity, it has been regarded since the Renaissance as

200-585: A praefect architectus armamentarius of the apparitor status group (a branch of the Roman civil service). He is mentioned in Pliny the Elder 's table of contents for Naturalis Historia (Natural History), in the heading for mosaic techniques. Frontinus refers to "Vitruvius the architect" in his late 1st-century work De aquaeductu . Likely born a free Roman citizen, by his own account Vitruvius served in

300-431: A Marcus Vitruvius Mamurra have been suggested as evidence that Vitruvius and Mamurra (who was a military praefectus fabrum under Julius Caesar ) were from the same family; or were even the same individual. Neither association, however, is borne out by De Architectura (which Vitruvius dedicated to Augustus ), nor by the little that is known of Mamurra. Vitruvius was a military engineer ( praefectus fabrum ), or

400-604: A scientific discipline as well as emphasising the skills of the artisan . One of Leonardo da Vinci 's best known drawings, the Vitruvian Man , is based on the principles of body proportions developed by Vitruvius in the first chapter of Book III, On Symmetry: In Temples And In The Human Body . The English architect Inigo Jones and the Frenchman Salomon de Caus were among the first to re-evaluate and implement those disciplines that Vitruvius considered

500-400: A 14th, Smyrnaeans . Myus, the third city, is described as being "long ago engulfed by the water, and its sacred rites and suffrage". This sentence indicates, at the time of Vitruvius's writing, it was known that sea-level change and/or land subsidence occurred. The layout of these cities is in general from south to north so that it appears that where Myrus should be located is inland. If this

600-410: A circle be described, it will touch his fingers and toes. It is not alone by a circle, that the human body is thus circumscribed, as may be seen by placing it within a square. For measuring from the feet to the crown of the head, and then across the arms fully extended, we find the latter measure equal to the former; so that lines at right angles to each other, enclosing the figure, will form a square. It

700-467: A head of water to be formed above the machine. The device is also described by Hero of Alexandria in his Pneumatica . The machine is operated by hand in moving a lever up and down. He mentioned its use for supplying fountains above a reservoir, although a more mundane use might be as a simple fire engine. One was found at Calleva Atrebatum ( Roman Silchester ) in England, and another is on display at

800-403: A heavily-influenced adaptation, while a 1692 translation was much abridged. English-speakers had to wait until 1771 for a full translation of the first five volumes and 1791 for the whole thing. Thanks to the art of printing, Vitruvius's work had become a popular subject of hermeneutics , with highly detailed and interpretive illustrations, and became widely dispersed. Of the many later editions,

900-456: A necessary element of architecture: arts and sciences based upon number and proportion . The 16th-century architect Palladio considered Vitruvius his master and guide, and made some drawings based on his work before conceiving his own architectural precepts. The earliest evidence of use of the stereographic projection in a machine is in De architectura , which describes an anaphoric clock (it

1000-427: A site will be high, neither misty nor frosty, and in a climate neither hot nor cold, but temperate; further, without marshes in the neighbourhood. For when the morning breezes blow toward the town at sunrise, if they bring with them mists from marshes and, mingled with the mist, the poisonous breath of the creatures of the marshes to be wafted into the bodies of the inhabitants, they will make the site unhealthy. Again, if

1100-474: A thorough philosophical approach and superb illustrations. Translations into Italian were in circulation by the 1520s, the first in print being the translation with new illustrations by Cesare Cesariano , a Milanese friend of the architect Bramante , printed in Como in 1521. It was rapidly translated into other European languages – the first French version was published in 1547 – and

1200-406: A type of regulator to control the heat in the hot rooms, a bronze disc set into the roof under a circular aperture, which could be raised or lowered by a pulley to adjust the ventilation. Although he did not suggest it himself, his dewatering devices such as the reverse overshot water-wheel likely were used in the larger baths to lift water to header tanks at the top of the larger thermae , such as

1300-550: A variety of information on Greek and Roman buildings, as well as prescriptions for the planning and design of military camps, cities, and structures both large (aqueducts, buildings, baths, harbours) and small (machines, measuring devices, instruments). Since Vitruvius published before the development of cross vaulting, domes, concrete , and other innovations associated with Imperial Roman architecture, his ten books give no information on these distinctive innovations of Roman building design and technology. From references to them in

1400-514: A wide variety of disciplines; in modern terms they would also be described as landscape architects, civil engineers, military engineers, structural engineers, surveyors, artists, and craftsmen combined. Etymologically the word architect derives from Greek words meaning 'master' and 'builder'. The first of the Ten Books deals with many subjects which are now within the scope of landscape architecture . In Book I, Chapter 1, titled The Education of

1500-550: Is a matter of conjecture, although various attempts have been made to visualise it. The early Christian practice of converting Roman basilicae (public buildings) into cathedrals implies the basilica may be incorporated into the Romanesque Fano Cathedral . In later years the emperor Augustus, through his sister Octavia Minor , sponsored Vitruvius, entitling him with what may have been a pension to guarantee financial independence. Whether De architectura

1600-424: Is cited as one of the earliest sources to connect lead mining and manufacture, its use in drinking water pipes, and its adverse effects on health. For this reason, he recommended the use of clay pipes and masonry channels in the provision of piped drinking-water. De architectura De architectura ( On architecture , published as Ten Books on Architecture ) is a treatise on architecture written by

1700-409: Is established. The topics range across many fields of expertise reflecting that in Roman times as today construction is a diverse field. Vitruvius is clearly a well-read man. In addition to providing his qualification, Vitruvius summarizes a recurring theme throughout the 10 books, a non-trivial and core contribution of his treatise beyond simply being a construction book. Vitruvius makes the point that

1800-571: Is famous for asserting in his book De architectura that a structure must exhibit the three qualities of firmitatis, utilitatis, venustatis – that is, stability, utility, and beauty. These are sometimes termed the Vitruvian virtues or the Vitruvian Triad . According to Vitruvius, architecture is an imitation of nature. As birds and bees built their nests, so humans constructed housing from natural materials, that gave them shelter against

1900-582: Is fulsome in his descriptions of religious buildings, infrastructure and machinery, he gives a mixed message on domestic architecture. Similar to Aristotle, Vitruvius offers admiration for householders who built their own homes without the involvement of an architect. His ambivalence on domestic architecture is most clearly read in the opening paragraph of the Introduction to Book 6. Book 6 focusses exclusively on residential architecture but as architectural theorist Simon Weir has explained, instead of writing

2000-528: Is now in the British Museum , and one from the latter in the National Museum of Wales . The remains were discovered when these mines were reopened in modern mining attempts. They would have been used in a vertical sequence, with 16 such mills capable of raising water at least 96 feet (29 m) above the water table. Each wheel would have been worked by a miner treading the device at the top of

2100-427: Is often credited as father of architectural acoustics for describing the technique of echeas placement in theaters. The only building, however, that we know Vitruvius to have worked on is one he tells us about, a basilica completed in 19 BC. It was built at Fanum Fortunae, now the modern town of Fano . The Basilica di Fano (to give the building its Italian name) has disappeared so completely that its very site

2200-647: Is presumed, fairly widespread among Romans. Roman military engineering Roman military engineering was of a scale and frequency far beyond that of its contemporaries. Indeed, military engineering was in many ways endemic in Roman military culture, as demonstrated by each Roman legionary having as part of his equipment a shovel, alongside his gladius (sword) and pila (spears). Fabri were workers, craftsmen, or artisans in Roman society. Descriptions of early Roman army structure (initially by phalanx, later by legion) attributed to king Servius Tullius state that two centuriae of fabri served under an officer,

The wire framework (the spider) and the star locations were constructed using the stereographic projection. Similar constructions dated from the 1st to 3rd centuries have been found in Salzburg and northeastern France, so such mechanisms were, it

2400-519: Is sometimes given as "Marcus Vitruvius Pollio", but both the first and last names are uncertain. Marcus Cetius Faventinus writes of "Vitruvius Polio aliique auctores"; this can be read as "Vitruvius Polio, and others" or, less likely, as "Vitruvius, Polio, and others". An inscription in Verona, which names a Lucius Vitruvius Cordo , and an inscription from Thilbilis in North Africa, which names

2500-436: Is speculated that Vitruvius served with Caesar's chief engineer Lucius Cornelius Balbus . 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 he was present. His service likely included north Africa , Hispania , Gaul (including Aquitaine ), and Pontus . To place

2600-507: Is the Naturalis Historia compiled by Pliny the Elder much later in c.  75 AD . The work is important for its descriptions of the many different machines used for engineering structures such as hoists , cranes and pulleys , as well as war machines such as catapults , ballistae , and siege engines . As a practising engineer, Vitruvius must be speaking from personal experience rather than simply describing

2700-446: Is the case, then since the writing of De architectura , the region has experienced either soil rebound or a sea-level fall. Though not indicative of sea-level change, or speculation of such, during the later-empire many Roman ports suffered from what contemporary writers described as 'silting'. The constant need to dredge ports became a heavy burden on the treasury and some have speculated that this expense significantly contributed to

2800-406: Is the development of the hypocaust , a type of central heating where hot air developed by a fire was channelled under the floor and inside the walls of public baths and villas . He gave explicit instructions on how to design such buildings so fuel efficiency is maximized; for example, the caldarium is next to the tepidarium followed by the frigidarium . He also advised using

2900-651: Is the only source for the siege of Larignum in 56 BC. Of the battlegrounds of the Gallic War there are references to: 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 (modern France), the Battle of Dyrrhachium of 48 BC (modern Albania), the Battle of Pharsalus in 48 BC (Hellas – Greece), the Battle of Zela of 47 BC (modern Turkey), and

3000-466: The Baths of Diocletian and the Baths of Caracalla . That Vitruvius must have been well practised in surveying is shown by his descriptions of surveying instruments, especially the water level or chorobates , which he compared favourably with the groma , a device using plumb lines . They were essential in all building operations, but especially in aqueduct construction, where a uniform gradient

3100-721: 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. Mainly 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 ; architectural engineers consider him

Vitruvius also mentioned the several automatons Ctesibius invented, and intended for amusement and pleasure rather than serving a useful function. Vitruvius outlined the many innovations made in building design to improve the living conditions of the inhabitants. Foremost among them

The use of the inverted siphon is described in detail, together with the problems of high pressures developed in the pipe at the base of the siphon, a practical problem with which he seems to be acquainted. He describes many different construction materials used for a wide variety of different structures, as well as such details as stucco painting. Concrete and lime receive in-depth descriptions.

As the only treatise on architecture to survive from antiquity, it has been regarded since the Renaissance as the first known book on architectural theory, as well as a major source on the canon of classical architecture . It contains

Publius Minidius is also 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

Although most Roman siege engines were adaptations from earlier Greek designs, the Romans were adept at engineering them swiftly and efficiently, as well as innovating variations such as the repeating ballista . The 1st century BC army engineer Vitruvius describes in detail many of

3800-440: The praefectus fabrum . Roman military engineering took both routine and extraordinary forms, the former a part of standard military procedure, and the latter of an extraordinary or reactive nature. Each Roman legion had a legionary fort as its permanent base. However, when on the march, particularly in enemy territory, the legion would construct a fortified camp or castra , using only earth, turf and timber. Camp construction

Late Professor of Classical Philology in Harvard University , is fully available at Project Gutenberg , and from the Internet Archive. The rediscovery of Vitruvius's work had a profound influence on architects of the Renaissance , prompting the rebirth of Classical architecture in subsequent centuries. Renaissance architects, such as Niccoli , Brunelleschi and Leon Battista Alberti , found in De architectura their rationale for raising their branch of knowledge to

Architecture is a science arising out of many other sciences, and adorned with much and varied learning; by the help of which a judgment is formed of those works which are the result of other arts. Practice and theory are its parents. Practice is the frequent and continued contemplation of the mode of executing any given work, or of the mere operation of

Though any original illustrations have been lost,

4300-507: The Roman conception, architecture needed to take into account everything touching on the physical and intellectual life of man and his surroundings. Vitruvius, thus, deals with many theoretical issues concerning architecture. For instance, in Book II of De architectura , he advises architects working with bricks to familiarise themselves with pre-Socratic theories of matter so as to understand how their materials will behave. Book IX relates

When invading enemy territories, the Roman army would often construct roads as it went, to allow swift reinforcement and resupply, or for easy retreat if necessary. Roman road-making skills were such that some survive. Michael Grant credits the Roman building of the Via Appia with winning them the Second Samnite War . The Roman army built projects for civilian use. When soldiers were not engaged in military campaigns,

These texts were not just copied, but also known at the court of Charlemagne, since his historian, bishop Einhard , asked the visiting English churchman Alcuin for explanations of some technical terms. In addition, a number of individuals are known to have read

4600-446: The abstract geometry of Plato to the everyday work of the surveyor . Astrology is cited for its insights into the organisation of human life, while astronomy is required for the understanding of sundials . Likewise, Vitruvius cites Ctesibius of Alexandria and Archimedes for their inventions, Aristoxenus ( Aristotle 's apprentice) for music, Agatharchus for theatre, and Varro for architecture. Vitruvius sought to address

4700-549: The amount of investment: tertia castra , quarta castra : "a camp of three days", "four days", etc. The engineers built bridges from timber and stone. Some Roman stone bridges survive. Stone bridges were made possible by the innovative use of keystone arches . One notable example was Julius Caesar's Bridge over the Rhine River . This bridge was completed in only ten days and is conservatively estimated to have been more than 100 m (300 feet) long. The construction

4800-402: The apparent laborer illnesses in the plumbum (lead pipe) foundries of his time. However, much of the water used by Rome and many other cities was very hard, minerals soon coated the inner surfaces of the pipes, so lead poisoning was reduced. Vitruvius related the famous story about Archimedes and his detection of adulterated gold in a royal crown. When Archimedes realized the volume of

4900-892: The arts, natural history and building technology. Vitruvius cites many authorities throughout the text, often praising Greek architects for their development of temple building and the orders ( Doric , Ionic and Corinthian ), and providing key accounts of the origins of building in the primitive hut . Though often cited for his famous "triad" of characteristics associated with architecture – utilitas, firmitas and venustas (utility, strength and beauty) – the aesthetic principles that influenced later treatise writers were outlined in Book III. Derived partially from Latin rhetoric (through Cicero and Varro), Vitruvian terms for order, arrangement, proportion, and fitness for intended purposes have guided architects for centuries, and continue to do so. The Roman author gives advice on

This post was always conferred on an officer of great skill, experience and long service, and who consequently was capable of instructing others in those branches of the profession in which he had distinguished himself. At various locations described by Vitruvius, battles and sieges occurred. He

The first printed edition ( editio princeps ), an incunabula version, was published by the Veronese scholar Fra Giovanni Sulpitius in 1486 (with a second edition in 1495 or 1496), but none were illustrated. The Dominican friar Fra Giovanni Giocondo produced the first version illustrated with woodcuts in Venice in 1511. It had

5200-478: The construction of sundials and water clocks ; and the design and use of machines in construction and warfare. He further divides building into public and private. Public building includes city planning, public security structures such as walls, gates and towers; the convenient placing of public facilities such as theatres, forums and markets, baths, roads and pavings; and the construction and position of shrines and temples for religious use. Later books are devoted to

5300-450: The construction of sundials and water clocks , and the use of an aeolipile (the first steam engine ) as an experiment to demonstrate the nature of atmospheric air movements (wind). Books VIII, IX, and X of De architectura form the basis of much of what is known about Roman technology, now augmented by archaeological studies of extant remains, such as the Pont du Gard in southern France. Numerous such massive structures occur across

5400-424: The cosmic order). In this book series, Vitruvius also wrote about climate in relation to housing architecture and how to choose locations for cities. Vitruvius is the first Roman architect to have written surviving records of his field. He himself cites older but less complete works. He was less an original thinker or creative intellect than a codifier of existing architectural practice. Roman architects practised

5500-538: The crown could be measured exactly by the displacement created in a bath of water, he ran into the street with the cry of " Eureka !", and the discovery enabled him to compare the density of the crown with pure gold. He showed the crown had been alloyed with silver, and the king was defrauded. Vitruvius described the construction of the Archimedes' screw in Chapter 10, although did not mention Archimedes by name. It

5600-515: The cultivation of vineyards. Soldiers became skilled in conducting mining operations such as building aqueducts needed for prospecting for metal veins, in activities such as hydraulic mining , and building reservoirs to hold water at the minehead. The knowledge and experience learned through routine engineering lent itself readily to extraordinary engineering projects. For such projects, Roman military engineering exceeded that of any of its contemporaries in imagination and scope. One notable project

The Roman Empire went far in exploiting water power, as the set of no fewer than 16 water mills at Barbegal in France demonstrates. The mills ground grain in a very efficient operation, and many other mills are now known, such as

5800-532: The early 9th century. This activity of finding and recopying classical manuscripts is part of what is called the Carolingian Renaissance . The London Vitruvius ( British Library, Harley 2767), the oldest surviving manuscript, includes only one of the original illustrations, a rather crudely drawn octagonal wind rose in the margin. This was written in Germany in about 800 to 825, probably at

5900-495: The elements. When perfecting this art of building, the Greeks invented the architectural orders: Doric , Ionic and Corinthian . It gave them a sense of proportion, culminating in understanding the proportions of the greatest work of art: the human body. This led Vitruvius in defining his Vitruvian Man , as drawn later by Leonardo da Vinci : the human body inscribed in the circle and the square (the fundamental geometric patterns of

6000-416: The ethos of architecture, declaring that quality depends on the social relevance of the artist's work, not on the form or workmanship of the work itself. Perhaps the most famous declaration from De architectura is one still quoted by architects: "Well building hath three conditions: firmness, commodity, and delight ". This quote is taken from Sir Henry Wotton 's version of 1624, and accurately translates

6200-522: The first German version followed in 1548. The first Spanish translation was published in 1582 by Miguel de Urrea and Juan Gracian. The most authoritative and influential edition was publicized in French in 1673 by Claude Perrault , commissioned by Jean-Baptiste Colbert in 1664. John Shute had drawn on the text as early as 1563 for his book The First and Chief Grounds of Architecture . Sir Henry Wotton 's 1624 work The Elements of Architecture amounts to

6300-468: The first book on architectural theory , as well as a major source on the canon of classical architecture . It is not clear to what extent his contemporaries regarded his book as original or important. He states that all buildings should have three attributes: firmitas , utilitas , and venustas ("strength", "utility", and "beauty"), principles reflected in much Ancient Roman architecture . His discussion of perfect proportion in architecture and

6400-522: The first illustrated edition was published in Venice in 1511 by Fra Giovanni Giocondo , with woodcut illustrations based on descriptions in the text. Bramante , Michelangelo , Palladio , Vignola and earlier architects are known to have studied the work of Vitruvius, and consequently it has had a significant impact on the architecture of many European countries. Little is known about Vitruvius' life. Most inferences about him are extracted from his only surviving work De Architectura . His full name

6500-425: The first illustrated edition was published in Venice in 1511 by Fra Giovanni Giocondo , with woodcut illustrations based on descriptions in the text. Later in the 16th-century Andrea Palladio provided illustrations for Daniele Barbaro 's commentary on Vitruvius, published in Italian and Latin versions. The most famous illustration is probably Da Vinci's Vitruvian Man . The surviving ruins of Roman antiquity,

6600-406: The first of their discipline, a specialization previously known as technical architecture. In his work describing the construction of military installations, he also commented on the miasma theory – the idea that unhealthy air from wetlands was the cause of illness, saying: For fortified towns the following general principles are to be observed. First comes the choice of a very healthy site. Such

6700-439: The former empire, a testament to the power of Roman engineering . Vitruvius's description of Roman aqueduct construction is short, but mentions key details especially for the way they were surveyed, and the careful choice of materials needed. His book would have been of assistance to Frontinus , a general who was appointed in the late 1st century AD to administer the many aqueducts of Rome . Frontinus wrote De aquaeductu ,

Theory is the result of that reasoning which demonstrates and explains that the material wrought has been so converted as to answer the end proposed. 2. Wherefore the mere practical architect is not able to assign sufficient reasons for the forms he adopts; and the theoretic architect also fails, grasping the shadow instead of

6900-403: The human body led to the famous Renaissance drawing of the Vitruvian Man by Leonardo da Vinci . Little is known about Vitruvius' life, but by his own description he served as an artilleryman, the third class of arms in the Roman military offices. He probably served as a senior officer of artillery in charge of doctores ballistarum (artillery experts) and libratores who actually operated

7000-408: The human body, and by extension, of the universe as a whole. In the introduction to book seven, Vitruvius goes to great lengths to present why he is qualified to write De Architectura . This is the only location in the work where Vitruvius specifically addresses his personal breadth of knowledge. Similar to a modern reference section, the author's position as one who is knowledgeable and educated

7100-530: The introduction on the virtues of residences or the family or some theme related directly to domestic life; Vitruvius writes an anecdote about the Greek ethical principle of xenia : showing kindness to strangers. De architectura is important for its descriptions of many different machines used for engineering structures, such as hoists, cranes , and pulleys , as well as war machines such as catapults , ballistae , and siege engines . Vitruvius also described

7200-410: The late 1st century AD to administer the many aqueducts of Rome), writing a century later, gives much more detail of the practical problems involved in their construction and maintenance. Surely Vitruvius' book would have been of great assistance in this. Vitruvius was writing in the 1st century BC when many of the finest Roman aqueducts were built, and survive to this day, such as those at Segovia and

7300-509: The legions had little to do, while costing the Roman state large sums of money. Thus, involving soldiers in building works, kept them well accustomed to hard physical labour and out of mischief, since it was believed that idle armies were a potential source of mutiny. Soldiers built many roads across the Empire. Soldiers were also put to use in the construction of town walls, the digging of canals, drainage projects, aqueducts, harbours, and even in

7400-475: The machines. As an army engineer he specialized in the construction of ballista and scorpio artillery war machines for sieges . It is possible that Vitruvius served with Julius Caesar 's chief engineer Lucius Cornelius Balbus . Vitruvius' De architectura was well-known and widely copied in the Middle Ages and survives in many dozens of manuscripts, though in 1414 it was "rediscovered" by

7500-618: The much later Hierapolis sawmill . Vitruvius described many different construction materials used for a wide variety of different structures, as well as such details as stucco painting. Cement , concrete , and lime received in-depth descriptions, the longevity of many Roman structures being mute testimony to their skill in building materials and design. He advised that lead should not be used to conduct drinking water, clay pipes being preferred. He comes to this conclusion in Book VIII of De architectura after empirical observation of

7600-560: The obsolescence of many specialized Latin terms used by Vitruvius and the loss of most of the original 10 illustrations thought by some to be helpful in understanding parts of the text. Vitruvius's work was "rediscovered" in 1416 by the Florentine humanist Poggio Bracciolini , who found it in the Abbey library of Saint Gall , Switzerland. He publicized the manuscript to a receptive audience of Renaissance thinkers, just as interest in

7700-489: The passage in the work, (I.iii.2) but English has changed since then, especially in regard to the word " commodity ", and the tag may be misunderstood. In modern English it would read: "The ideal building has three elements; it is sturdy, useful, and beautiful." Vitruvius also studied human proportions (Book III) and this part of his canones were later adopted and adapted in the famous drawing Homo Vitruvianus (" Vitruvian Man ") by Leonardo da Vinci . While Vitruvius

7800-703: The preface of Book I, Vitruvius dedicates his writings to giving personal knowledge of the quality of buildings to the emperor. Likely Vitruvius is referring to Marcus Agrippa 's campaign of public repairs and improvements. This work is the only surviving major book on architecture from classical antiquity . According to Petri Liukkonen, this text "influenced deeply from the Early Renaissance onwards artists, thinkers, and architects, among them Leon Battista Alberti (1404–1472), Leonardo da Vinci (1452–1519), and Michelangelo (1475–1564)." The next major book on architecture, Alberti's reformulation of Ten Books ,

7900-563: The qualifications of an architect (Book I) and on types of architectural drawing. The ten books or scrolls are organized as follows: De architectura – Ten Books on Architecture Roman architects were skilled in engineering, art, and craftsmanship combined. Vitruvius was very much of this type, a fact reflected in De architectura . He covered a wide variety of subjects he saw as touching on architecture. This included many aspects that may seem irrelevant to modern eyes, ranging from mathematics to astronomy, meteorology, and medicine. In

8000-477: 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 [Prefect], had a post of no small importance. The position of the camp, the direction of the entrenchments, the inspection of

8100-460: The substance. He who is theoretic as well as practical, is therefore doubly armed; able not only to prove the propriety of his design, but equally so to carry it into execution. He goes on to say that the architect should be versed in drawing, geometry, optics (lighting), history, philosophy, music, theatre, medicine, and law. In Book I, Chapter 3 ( The Departments of Architecture ), Vitruvius divides architecture into three branches, namely; building;

8200-418: The tents or huts of the soldiers and the baggage were comprehended in his province. His authority extended over the sick, and the physicians who had the care of them; and he regulated the expenses relative thereto. He had the charge of providing carriages, bathhouses and the proper tools for sawing and cutting wood, digging trenches, raising parapets, sinking wells and bringing water into the camp. He likewise had

8300-548: The text or have been indirectly influenced by it, including: Vussin , Hrabanus Maurus , Hermann of Reichenau , Hugo of St. Victor , Gervase of Melkley , William of Malmesbury , Theodoric of Sint-Truiden , Petrus Diaconus , Albertus Magnus , Filippo Villani , Jean de Montreuil , Petrarch , Boccaccio , Giovanni de Dondi , Domenico Bandini , Niccolò Acciaioli bequeathed copy to the Basilica of San Lorenzo, Florence , Bernward of Hildesheim , and Thomas Aquinas . In 1244

8400-423: The text, we know that there were at least a few illustrations in original copies (perhaps eight or ten), but perhaps only one of these survived in any medieval manuscript copy. This deficiency was remedied in 16th-century printed editions, which became illustrated with many large plates. Probably written between 30–20 BC, it combines the knowledge and views of many antique writers, Greek and Roman, on architecture,

8500-412: The town is on the coast with southern or western exposure, it will not be healthy, because in summer the southern sky grows hot at sunrise and is fiery at noon, while a western exposure grows warm after sunrise, is hot at noon, and at evening all aglow. Frontinus mentions Vitruvius in connection with the standard sizes of pipes : probably the role for which he was most widely respected in Roman times. He

8600-406: The understanding, design and construction of each of these. In Book III, Chapter 1, Paragraph 3, Vitruvius writes about the proportions of man: 3. Just so the parts of Temples should correspond with each other, and with the whole. The navel is naturally placed in the centre of the human body, and, if in a man lying with his face upward, and his hands and feet extended, from his navel as the centre,

8700-457: The wheel, by using cleats on the outer edge. That they were using such devices in mines clearly implies that they were entirely capable of using them as water wheels to develop power for a range of activities, not just for grinding wheat, but also probably for sawing timber, crushing ores, fulling , and so on. Ctesibius is credited with the invention of the force pump , which Vitruvius described as being built from bronze with valves to allow

8800-696: The work of some of the most talented is unknown, while many of those of lesser talent but greater political position are famous. This theme runs through Vitruvius's ten books repeatedly – echoing an implicit prediction that he and his works will also be forgotten. Vitruvius illustrates this point by naming what he considers the most talented individuals in history. Implicitly challenging the reader that they have never heard of some of these people, Vitruvius goes on and predicts that some of these individuals will be forgotten and their works lost , while other, less deserving political characters of history will be forever remembered with pageantry. Vitruvius' De architectura

8900-404: The works of others. He also describes the construction of sundials and water clocks , and the use of an aeolipile (the first steam engine ) as an experiment to demonstrate the nature of atmospheric air movements (wind). His description of aqueduct construction includes the way they are surveyed, and the careful choice of materials needed, although Frontinus (a general who was appointed in

9000-553: Was "rediscovered" in 1414 by the Florentine humanist Poggio Bracciolini in the library of Saint Gall Abbey . Leon Battista Alberti (1404–1472) publicised it in his seminal treatise on architecture, De re aedificatoria ( c.  1450 ). The first known Latin printed edition was by Fra Giovanni Sulpitius in Rome, 1486. Translations followed in Italian ( Cesare Cesariano , 1521), French (Jean Martin, 1547), English, German ( Walther H. Ryff , 1543) and Spanish and several other languages. The original illustrations had been lost and

9100-454: Was a device widely used for raising water to irrigate fields and dewater mines. Other lifting machines mentioned in De architectura include the endless chain of buckets and the reverse overshot water-wheel . Remains of the water wheels used for lifting water have been discovered in old mines such as those at Rio Tinto in Spain and Dolaucothi in west Wales. One of the wheels from Rio Tinto

9200-636: Was clear that he had set down his own discoveries. James Anderson's "The Constitutions of the Free-Masons" (1734), reprinted by Benjamin Franklin, describes Vitruvius as "the Father of all true Architects to this Day." Vitruvius is the author of De architectura, libri decem , known today as The Ten Books on Architecture , a treatise written in Latin on architecture, dedicated to the emperor Augustus. In

9300-519: Was deliberately over-engineered for Caesar's stated purpose of impressing the Germanic tribes, who had little experience of engineering, and to emphasise that Rome could travel wherever she wished. Caesar was able to cross over the completed bridge and explore the area uncontested, before crossing back over the subsequently dismantled bridge. Caesar related in his War in Gaul that he "sent messengers to

9400-754: Was important to provision of a regular supply of water without damage to the walls of the channel. He described the hodometer , in essence a device for automatically measuring distances along roads, a machine essential for developing accurate itineraries, such as the Peutinger Table . In Book IV Chapter 1 Subsection 4 of De architectura is a description of 13 Athenian cities in Asia Minor , "the land of Caria ", in present-day Turkey. These cities are given as: Ephesus , Miletus , Myus , Priene , Samos , Teos , Colophon , Chius , Erythrae , Phocaea , Clazomenae , Lebedos , Mytilene , and later

9500-546: Was inspired by De Architectura as well as surviving Roman monuments such as the Pantheon and the Baths of Diocletian . Latin Italian French English Books VIII, IX and X form the basis of much of what we know about Roman technology, now augmented by archaeological studies of extant remains, such as the water mills at Barbegal in France. The other major source of information

9600-479: Was not written until 1452. However, we know there was a significant body of writing about architecture in Greek, where "architects habitually wrote books about their work", including two we know of about the Parthenon alone. To A. W. Lawrence , Vitruvius "has recorded a most elaborate set of rules taken from Greek authors, who must have compiled them gradually in the course of the preceding centuries". Vitruvius

9700-424: Was the circumvallation of the entire city of Alesia and its Celtic leader Vercingetorix , within a massive double-wall – one inward-facing to prevent escape or offensive sallies, and one outward-facing to prevent attack by Celtic reinforcements. This wall is estimated to have been over 20 km (12 mi) long. A second example is the massive ramp built using thousands of tons of stones and beaten earth up to

9800-428: Was the responsibility of engineering units to which specialists of many types belonged, officered by architecti (engineers), from a class of troops known as immunes who were excused from regular duties. These engineers would requisition manual labour from the soldiers at large as required. A legion could throw up a camp under enemy attack in a few hours. The names of the different types of camps apparently represent

9900-416: Was upon these writings that Renaissance engineers, architects and artists like Mariano di Jacopo Taccola , Pellegrino Prisciani and Francesco di Giorgio Martini and finally Leonardo da Vinci based the illustration of the Vitruvian Man . Vitruvius described the human figure as being the principal source of proportion. The drawing itself is often used as an implied symbol of the essential symmetry of

10000-462: Was written by one author or is a compilation completed by subsequent librarians and copyists, remains an open question. The date of his death is unknown, which suggests that he had enjoyed only a little popularity during his lifetime. Gerolamo Cardano , in his 1552 book De subtilitate rerum , ranks Vitruvius as one of the 12 persons whom he supposes to have excelled all men in the force of genius and invention; and might have given him first place if it
