At the sanctuary site of Sant’Omobono, fired clay collars capped wooden column shafts of a shrine dated to the 6th century bce (fig. Bloomington: Indiana University Press, 1994. Cappellaccio tuff, a friable type of inferior quality, is Rome’s most local and earliest-used type. Ashlars of Cappellaccio Tuff Laid in Alternating Courses of Headers and Stretchers Make Up the Foundations of the Temple of Jupiter Optimus Maximus on the Capitoline Hill, Rome. Glass mosaic was used sparingly at first for decorating walls and ceilings, especially fountains and niches within walls and on the intradoses of vaults. A layer of mortar and shims of marble scraps or terracotta provided the adhesive backing. Figure 1. The facings as described in the order above developed in a more or less diachronic fashion from the mid-2nd century bce onwards, with reticulate work appearing in the latter half of the 1st century bce. 909. Iron tie bars also worked from under and within the span of the vault to counteract lateral thrust (see “Metals and Fastening Systems” section). Romans were well aware that some species resisted rot better than others when exposed to damp conditions. Thus the intricate woven nests of swallows offered a template for the invention of wattle and daub, a construction technique characterized by the packing of mud or plaster upon a tightly woven panel of twigs (De arch. 11. The triangular truss was capable of clearing spans of up to one hundred Roman feet, surpassing even the greatest of the cross vaults (see “Vaulting in Stone, Brick, and Concrete” section). Unable to add item to List. The strata of soft tuffs lie close to the surface and are relatively easy to quarry. To eliminate cracking, holes for the nails were set in the clay before firing. 8. Pat.1.11.5). “Flat” or “lintel” Arch Construction: Forum Portico at Pompeii, mid-1st Century ce, and Diocletian’s Palace at Split, c. 300 ce. Thus bronze was prized as sheathing for buildings (especially roofing; e.g., the gilt-bronze tiles of the Temple of Jupiter Optimus Maximus; Plin. Articles traitant de Adam, Jean Pierre. By the Imperial period Roman builders took advantage of local sources of this “pozzolana” sand (Lat: harena fossicia) that resulted in the characteristic reddish and black-grained mortars seen in so many buildings of Imperial date in the capital. The materials used, construction techniques employed, and architectural styles for structures for government, entertainment, dwellings, bridges, and aqueducts will be discussed. Much of the process of involving opus caementicium was repetitive and—other than conceiving the design itself, the centring work, and the decorative finishes—involved much unskilled labour. Later, when concrete was favoured for the foundations of large structures during the Imperial period, wood played an important role as the rigid form (“shuttering”) that held the concrete in place until it could cure. It looks at large- scale public buildings as well as more modest homes and shops. Deposits of this substance lay only a few kilometres from the city centre of Rome. Placing emphasis on the technical aspects of the subject, the author follows the process of building through each stage -- from quarry to standing wall, from tree to roof timbers -- and describes how these materials … The 13-digit and 10-digit formats both work. Columns and floor and wall revetments of imported marbles graced both public and private buildings. Guido Calza, ed., Scavi di Ostia. These first successful attempts anticipate the sophisticated centrally planned designs with “pumpkin” or parasol domes that appear in the late 1st century (e.g., Domitian’s palace in Rome, late 1st century ce) and beyond. 2. Heinrich Bauer, “Un tentativo di ricostruzione degli Horrea Agrippiana,” Archaeologia Classica 30 (1978): 132–146; Heinrich Bauer and A. Pronti, “Elementi architettonici degli Horrea Agrippiana,” Archaeologia Classica 30 (1978): 107–131; and Heinrich Bauer and A. Pronti, “Basilica Aemilia,” in Kaiser Augustus und die verlorene Republic: eine Austellung im Martin-Gropius-Bau, Berlin, 7. HN 33.57) or for elements such as doors, which could employ a laminate of bronze over a wooden frame (Plin. (Mainz: Philipp von Zabern, 1988), 200–212. The so-called flat (or lintel) arch offered another solution for achieving wide horizontal spans in stone; voussoirs of stone in horizontal courses stayed in place through gravitational force and lateral compression (fig. 1). Beds of clay, including significant deposits right in the middle of the city, provided the raw material for fired roof tiles, architectural revetments, and bricks. ... Greek and Roman building practice was everywhere based on locally available materials. The emergence of the field of Classical archaeology in the 19th century fostered the first modern systematic studies, such as Auguste Choisy’s L’Art de bâtir chez les Romans published in 1873. The Italian quarries at Luna represented the most important Italian source of white marble beginning in the mid-1st century bce and were in full production by the reign of Augustus. Roofing represents the most prevalent use of wooden framing in construction. Gabriele Cifani, Architettura romana arcaica: edilizia e società tra monarchia e repubblica (Rome: L’Erma di Bretschneider, 2008). Small special-purpose bricks were laid on edge in a herringbone pattern (opus spicatum; see fig. With few exceptions (e.g., vaulting tubes), Roman forms and methods of vaulting required preliminary centring work of suitable beams and planks (fig. At least one depiction (on Trajan’s Column) and literary description (Dio Cass. 10). 113 ce) and the Baths of Trajan, of Caracalla, and of Diocletian, all show evidence of the use of tie bars. As Rome’s territory and technological know-how expanded through the republican and imperial periods, Roman builders gained more materials and techniques with which to work. Dome of Cut Stone from the West Baths at Gerasa. Translucent stones (like alabaster) could serve as windowpanes. De arch. Marcello Spanu, “L’impiego di anfore nelle volte romane e tardo-antiche: distribuzione e modalità,” Daidalos: Studi e ricerche del Dipartimento di Scienze del Mondo Antico 8 (2007): 185–223. They also treated wood with various concoctions or charred it to help with rot resistance. 5.1.7), and planked structures on piles represented on Trajan’s Column (113 ce) are recognized by scholars as a form of Dacian architecture. The harbour project at the colony site of Cosa presents an early use (once thought to be 2nd century BCE but recently proposed as Augustan) of this technology. The topic continued to attract much scholarly attention in the opening decades of the 20th century. 20.3). The inwardly “impluviate” sloping roofs of Roman atrium houses were all framed with wood, and wooden beams supported interior and exterior balconies and the shed-type roofs that projected over doorways and sidewalks. Manufactured materials consisted of brick and glass and composite materials consisted of concrete. With over 750 illustrations, Roman Buildings is a thorough and systematic examination of Roman architecture and building practice, looking at large-scale public buildings as well as more modest homes and shops. Walls of unfired mud brick have been found in many parts of the Roman world, from all periods, and rammed earth (pisé, or paries formaceus) construction is described by Pliny as characteristic of North Africa and Spain (Plin. It looks at large- scale public buildings as well as more modest homes and shops. Robert Hohlfelder, “Constructing the Harbour of Caesarea Palaestina, Israel: New Evidence from ROMACONS Field Campaign of October 2005,” International Journal of Nautical Archaeology 36 (2007): 409–415; and, for chronological development, Christopher J. Brandon, Robert L. Hohlfelder, Marie D. Jackson, John P. Oleson, Building for Eternity: The History and Technology of Roman Concrete Engineering in the Sea (Oxford: Oxbow Books, 2014). When submerged below the level of ground water, wood is very resistant to decomposition; wooden pipes were sometimes substituted for lead to channel water to and from buildings. Id.) For most of the Archaic period, horizontal wooden beams, often revetted with terracotta, served in this role. Coffering and variable thickness of the vault (a thinner cross section near the crown) reduced the overall mass. Brief content visible, double tap to read full content. The opening of the 21st century has seen new work on specific applications, for example, methods of vaulting by Lynne Lancaster19 and timbered construction by Roger Ulrich.20, Pioneering 19th-century and subsequent attempts to classify and date Roman building types by construction method have been questioned in recent years. City gates (e.g., the Porta di Giove at Falerii Novi, after 241 bce) represent the earliest extant large-scale surviving voussoir arches of tuff (fig. First century ce. Review: Roman Building: Materials and Techniques by Jean-Pierre Adam, Anthony Mathews; Technics and Architecture. For the latter, clusters of wooden beams were used to support superstructures even when the piers emerging from the water were built of stone (e.g., at Roman Trier, 1st century ce). Building materials and techniques, Greek and Roman. Blacksmiths shaped iron for use as clamps, tie bars, lewises (for lifting), nails, window frames, sheathing for piles, and all manner of straps and braces. Does this book contain quality or formatting issues? 7. The new portico still under construction in Pompeii’s forum in 79 ce offers an example in a local marble, as does the finely cut “keyed” stonework of Diocletian’s palace at Split built nearly 250 years later. Even provincial cities of the Imperial period that had neither the tradition of working with clay nor good sources of the raw material show evidence of Italic-style brickwork in some applications like apses and vaulting (e.g., the Severan basilica at Lepcis Magna, early 3rd century ce). The Italian engineer and architect Gustavo Giovannoni published La tecnica della costruzione presso i romani in 1925. Houses and temples of the Archaic period were generally covered with beams employed in what is known as a “prop-and-lintel” system, where heavy purlins, ridgepoles, and the rafters they carried were supported by vertical “props” placed directly over interior walls and columns. It won't leave our house because we're Roman Archeology fanatics. Figure 16. Materials used in the construction of the Colosseum were chosen carefully. The practice of stamping bricks before firing (usually at a temperature of c. 800° C) with an identifying mark has proved to be an indispensable aid for dating construction.3 Walls of solid brickwork (e.g., the temple of Serapis at Pergamon, 2nd century ce) are less common and associated with provincial architecture in Asia Minor. Important deposits adjacent to the banks of rivers (e.g., “Anio” tuff) facilitated the transport of blocks downriver, especially to areas where there was no suitable local building stone (the first walls of Rome’s port town of Ostia, of Fidene tuff, are a good example). It gained in popularity over time and by late antiquity played a significant role in the decoration of upper walls and vaults, especially those of early Christian tombs and churches. A short distance up the coast from Rome a “metal-bearing” range of mountains (Catena Metallifera) initially yielded significant amounts of iron ore; blacksmiths forged the smelted iron into millions of fasteners, such as iron clamps and tie bars that strengthened both stone and concrete construction. Volcanic basalt (silex or selce), hard and durable, paved Roman roadbeds from the 3rd century bce. The process of cutting and assembling patterned wall revetments of stone (opus sectile) was essentially the same in technique and appearance as that used for floor covering (fig. Vertical forked sticks (furcae) supporting horizontal poles of saplings or trimmed limbs defined the fundamental elements of post-and-lintel architecture that would later be realized in shaped dry stone and then concrete masonry. At the tops of the piers of a cross-vaulted system, arched buttresses anticipated the medieval “flying” buttress solution (e.g., Markets of Trajan, 113 ce; Basilica Nova, early 4th century ce). As Rome grew wealthier and expanded abroad, patrons and builders imported marble to the capital from the Aegean, well before the discovery of more local, Italian sources. Such floors comprised a set of heavy support joists of squared or round timbers embedded into the side walls, one or two layers of floorboards attached with iron nails, and top layers of masonry (Vitr. He imagined primeval builders observing and imitating the practices of animals. There was a problem loading your book clubs.

After viewing product detail pages, look here to find an easy way to navigate back to pages you are interested in. Here are some facts about Roman buildings. Nothing, however, was as transformative as the adoption of concrete in the late 3rd century bce, the mass production of fired brick, and the ensuing experimentation that resulted in the vaulted structures that have become the hallmark of Roman architecture. First century bce. We've got a copy ourselves. A large dwelling that stood in the “Sepulcretum” area of the future Roman forum sometime after 650 bce offers one of the earliest examples. Sixth-century Rome witnessed rapid expansion of squared-stone construction (opus quadratum) with local tuffs. Jean-Pierre Adam. Wooden architraves are superior to stone in terms of tensile strength, thus early porticoes and colonnaded porches exhibit broad intercolumniations. So we got a new copy for this Master Craftsman who does stone work in old houses, churches and our early 19th century house. The practice of using fired clay for sheathing roofs and exposed wooden beams began in Rome in the second half of the 7th century bce. Metals served as significant and in some applications essential components of Roman architecture. He shares it with his father, the previous generation. The rafters of the prop and lintel are supported by the vertical “props.” Here four props plus a ridgepole are employed. As we mentioned earlier in this article the Romans made use of various building techniques in their architecture such as the use of the arch and the vault. Flue Tiles Embedded in a Heated Room in the Baths of Buticosus, Ostia. 12). While floor mosaics (opus musivum, tessellatum, or vermiculatum) consist largely of cut-stone tesserae, glass mosaics offered brilliant colour palettes and pleasing light effects. I'm giving five stars because it's an excellent book and I highly recommend it. In the west, the medium of concrete, sometimes in concert with stone or brick ribbing, was the preferred medium for the construction of volumetric vaulting. 14). Roman Building: Materials and Techniques JEAN-PIERRE ADAM. Coatings of stucco on mixed tuff and travertine construction presented surfaces uniform in texture and color. Various forms of brick ribbing appear in Roman concrete vaults from the 1st century ce; by the 4th century, brick ribbing was integral to concrete vaulting in Rome.4 Interlocking tubes of terracotta arranged in closely spaced rows made it possible to build vaults without wooden centring; the practice is first documented from the 3rd century bce in Sicily and was particularly popular in North Africa.5 For the baths of Roman Britain, builders even experimented with barrel vaults fashioned from voussoirs of hollow fired brick.6 Such use would have lightened the vault, a clear desire of high-late Imperial builders who often incorporated empty ceramic amphorae into vaulting in an effort to lessen the overall mass of the construction.7 Amphorae have also been found buried under walls to stabilize loose or wet substrates and to improve drainage; the practice has been documented in the area of the Po watershed. Wood played a role in all phases of construction and in all parts of the building, even for foundations. … Its full potential (and perhaps its actual introduction) is seen with the construction of the great civic basilican halls that first appeared in the 2nd century bce. Figure 7. Cut-stone construction and tight-fitting timber joinery require a highly skilled labour force. Michael Fulford and Andrew Wallace-Hadrill, “Towards a History of Pre-Roman Pompeii. 2.1.4). The easiest and the most wasteful way to build entirely of wood was by using notched logs, an exotic practice described by Vitruvius (De arch. The coloured marbles that embellished the buildings of Rome served as physical testimony to Rome’s control over the eastern Mediterranean. 13. The link was not copied. Recent excavations in the Monte Testaccio area of Rome have revealed that tightly-packed “recycled” amphorae placed in superimposed rows formed the walls of some utilitarian buildings in the port area. Most doors, door and window frames, and window shutters were made of wood. In terms of architectural scale and speed of construction, the adoption of opus caementicium was a game-changer. 1 Review. Reconstructions show placement both below the vault (and thus visible) and embedded within the top of the vault. 13) for a durable, attractive, and inexpensive floor. A final protective, often decorative, sheathing covered most wall facings, however attractive the underlying stone or brickwork. Good beds of clay suitable for roofing tiles and architectural terracottas have been found in the area of the Velabrum in Rome; the use of local clay suggests local production. Please try again. These materials were available within close proximity to the city of Rome and generally 14 The project in Ostia benefitted greatly from the participation of Herbert Bloch, who changed the study of Roman building practice and the dating of brick construction by his methodical studies of Roman brick … While bronze is not as strong as iron under tension, it nevertheless offers some distinct advantages: it is attractive and durable, especially when employed in the form of relatively thin sheets. By the 1st century bce, travertine keystones and springers offered extra strength at points of stress (e.g., for the interior vaults of the Theatre of Marcellus). The Encyclopedia of Ancient History. Masonry vaulting presents two particular challenges: overall weight and problems associated with lateral thrust. 15). Figure 4. Roman Building Techniques. Baltimore: Johns Hopkins University Press écrits par GIACOBBE GIUSTI Topografia Generale (Rome: La Libreria dello Stato, 1953). Strabo mentions such construction for the area of Ravenna (Geog. To build a wall or a vault, labourers combined the caementa and the mortar layer by layer. Figure 12. 1 vol. You could not be signed in, please check and try again. Hazel Dodge. To or from the source, and see Adam 1994, 26-29 for technique and visual.These two books give us a portrait of knowledge in Rome, at the beginning. Routledge; 1st edition (November 1, 2005), Up to 4 simultaneous devices, per publisher limits. Excavated terracotta fragments, including antefixes and friezes, exhibit orientalizing motifs like gorgon heads, minotaurs, and animal processions.2 Terracotta roofing tiles remained in use throughout the Roman period, while terracotta revetments faded in importance at the beginning of the Imperial period as stone entablatures and concrete vaulting replaced wooden beams. Fired clay played an increasingly important role in Roman vaulting. He also teaches at the Ecole de Chaillot, which prepares architects for work on the historic monuments and buildings of France. Khan Academy is a 501(c)(3) nonprofit organization. Later, harder stones were used, like peperino and local albani stone from the Alban hills. For foundations on land, timber shuttering, the earthen walls of the foundation trench, or a retaining wall of fired brick, served as forms for the concrete. He has more time so he reads it first. Bronze, too, appeared in the form of pins, hardware such as hinges, sheathing for roofs, and even structural beams. Marbles and granite: Q. Caecilius Metellus is credited with building the first marble temple in Rome in 146 bce (perhaps that of Jupiter Stator in the Porticus Metelli; Vell. Julius Caesar’s famous description of the bridge he built over the Rhine took the form of a series of trestles that supported horizontal timbers; the passage offers important Latin vocabulary for such structural members (Caes. Ashlars of tuff cut to uniform dimensions were employed extensively well into the Imperial period for foundations, fortifications, and temple podia—virtually any application where strength and durability were desired. ... Strickland, Michael, "Roman Building Materials, Construction Methods, and Architecture: The Identity of an Empire" (2010). Rome’s earliest builders sourced materials obtainable from the immediate environment and transformed them using practical knowledge. Sanctuary of San Omobono, Rome. Volcanic ash from Puteoli near Naples and later similar ash from areas in the immediate vicinity of Rome contained both silica and alumina that reacted with the slaked lime to create a mortar that could also harden underwater. Prop-and-Lintel (Top) vs. Timber-Truss Roofing Systems. Women classicists played prominent roles as pioneers of this field, notably Esther Boise Van Deman (1862–1937) and Marion Elizabeth Blake (1892–1961). These early Romanesque Revival structures resembled Gothic predecessors with Roman forms, primarily for civic buildings. 4.17). Roman walls of faced concrete opus caementicium commonly incorporated brick-relieving arches over areas of weakness, like doors, windows, or deep interior niches. Bipedales Tiles Pave a Floor in the Domus dei Mosaici at Roselle, Italy. “Step-rings” in masonry built along the shoulders of domes retarded the tendency for the curing or shrinking/expanding concrete to crack. Special-use fired bricks with customized forms appeared in applications where builders sought resistance to heat and moisture or opted for ready-made materials to ease construction (fig. Figure 10. 12. From the Interior of the Mausoleum of Augustus, Rome. The development of iron tools, particularly those with sharp cutting edges—including axes, adzes, picks, saws, drill bits, and chisels—over the course of the Archaic period greatly facilitated the extraction and processing of raw materials and the speed of execution and scale of architectural projects. The annular and coffered vaults of the hemicycles of the Fortuna Primigenia sanctuary in Tivoli (late 2nd century bce), for example, anticipate by 150 years the revolution in vaulted designs attributed to Nero in Rome. Barrel vaults placed at right angles to the bays of large cross vaults—such as those of the Imperial bath buildings and the Basilica Nova in Rome (early 4th century ce)—opposed lateral forces. At the south portico of the forum of Pompeii (1st century bce) wooden architraves once supported upper frieze and cornice courses of tuff stone. Second Century ce. Raw materials, organized labour, and scaled-up technology necessary for manufacturing the large numbers of tiles required to cover a roof appear at just about the same time that Roman houses and public buildings expanded from the hills of the future city to the area of the forum valley. Tuff: Tuff (Italian “tufo,” in many English textbooks “tufa”) deposits in central Italy are extensive and easily accessed; there are several good sources in and around the city of Rome. Unlike their modern counterparts, the Roman fired brick is often triangular in shape, with one side forming the face of the wall and the two others facing the core, offering an ideal bonding face with the concrete. Unworked wood (“roundwood”), clay, and stone were the primal materials for building and never fell out of use. The first copy went astray so we got in touch with the supplier who was brilliant and got a replacement. No Roman description of centring survives; even the Latin term for it is uncertain, but its employment is manifest everywhere, from the imprints of the boards used still visible on the undersides (intradoses) of concrete vaults to the projecting stone blocks left on aqueduct projects (e.g., Pont du Gard, 1st century ce) and other buildings that supported the centring while the vault was under construction. 3). City: A Story of Roman Planning and Construction, The Archaeology of Sanitation in Roman Italy: Toilets, Sewers, and Water Systems (Studies in the History of Greece and Rome), Wheelock's Latin, 7th Edition (The Wheelock's Latin Series), Jean-Pierre Adam has been Director of the Paris office of the Institut de Recherche sur L'Archtitecture (CNRS) since 1972.
