Roman Architecture
Ancient Roman architecture adopted the external language of classical Greek architecture for the purposes of the ancient Romans, but was different from Greek buildings, becoming a new architectural style. The two styles are often considered one body of classical architecture. Roman architecture flourished in the Roman Republic and to even a greater extent under the Empire, when the great majority of surviving buildings were constructed. It used new materials, particularly Roman concrete, and newer technologies such as the arch and the dome to make buildings that were typically strong and well-engineered. Large numbers remain in some form across the former empire, sometimes complete and still in use to this day. Roman architecture covers the period from the establishment of the Roman Republic in 509 BC to about the 4th century AD, after which it becomes reclassified as Late Antique or Byzantine architecture. Few substantial examples survive from before about 100 BC, and most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Colosseum
The Colosseum ( ; it, Colosseo ) is an oval amphitheatre in the centre of the city of Rome, Italy, just east of the Roman Forum. It is the largest ancient amphitheatre ever built, and is still the largest standing amphitheatre in the world today, despite its age. Construction began under the emperor Vespasian () in 72 and was completed in 80 AD under his successor and heir, Titus (). Further modifications were made during the reign of Domitian (). The three emperors that were patrons of the work are known as the Flavian dynasty, and the amphitheatre was named the Flavian Amphitheatre ( la, Amphitheatrum Flavium; it, Anfiteatro Flavio ) by later classicists and archaeologists for its association with their family name (Flavia (gens), Flavius). The Colosseum is built of travertine#Uses, travertine limestone, tuff (volcanic rock), and brick-faced Roman concrete, concrete. It could hold an estimated 50,000 to 80,000 spectators at various points in its history, having an average a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Etruscan Architecture
Etruscan architecture was created between about 900 BC and 27 BC, when the expanding civilization of ancient Rome finally absorbed Etruscan civilization. The Etruscans were considerable builders in stone, wood and other materials of temples, houses, tombs and city walls, as well as bridges and roads. The only structures remaining in quantity in anything like their original condition are tombs and walls, but through archaeology and other sources we have a good deal of information on what once existed. From about 630 BC, Etruscan architecture was heavily influenced by Greek architecture, which was itself developing through the same period. In turn it influenced Roman architecture, which in its early centuries can be considered as just a regional variation of Etruscan architecture. But increasingly, from about 200 BC, the Romans looked directly to Greece for their styling, while sometimes retaining Etruscan shapes and purposes in their buildings. The main monumental forms of Etru ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hypocaust
A hypocaust ( la, hypocaustum) is a system of central heating in a building that produces and circulates hot air below the floor of a room, and may also warm the walls with a series of pipes through which the hot air passes. This air can warm the upper floors as well. The word derives from the Ancient Greek meaning "under" and , meaning "burnt" (as in ''caustic''). The earliest reference to such a system suggests that the temple of Ephesus in 350 BC was heated in this manner, although Vitruvius attributes its invention to Sergius Orata in c. 80 BC. Its invention improved the hygiene and living conditions of citizens, and was a forerunner of modern central heating. Roman operation Hypocausts were used for heating hot baths and other public buildings in Ancient Rome. They were also used in private homes. It was a must for the villas of the wealthier merchant class throughout the Roman Empire. The ruins of Roman hypocausts have been found throughout Europe (for example in Ital ...

Civil Engineering
Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewage systems, pipelines, structural components of buildings, and railways. Civil engineering is traditionally broken into a number of sub-disciplines. It is considered the second-oldest engineering discipline after military engineering, and it is defined to distinguish non-military engineering from military engineering. Civil engineering can take place in the public sector from municipal public works departments through to federal government agencies, and in the private sector from locally based firms to global Fortune 500 companies. History Civil engineering as a discipline Civil engineering is the application of physical and scientific principles for solving the problems of society, and its history is intricately linked to advances in t ...

Crisis Of The Third Century
The Crisis of the Third Century, also known as the Military Anarchy or the Imperial Crisis (AD 235–284), was a period in which the Roman Empire nearly collapsed. The crisis ended due to the military victories of Aurelian and with the ascension of Diocletian and his implementation of reforms in 284, including the Tetrarchy. The crisis began in 235 with the assassination of Emperor Severus Alexander by his own troops. During the following 50-year period, the Empire saw the combined pressures of barbarian invasions and migrations into the Roman territory, civil wars, peasant rebellions and political instability, with multiple usurpers competing for power. This led to the debasement of currency and economic collapse, with the Plague of Cyprian contributing to the disorder. Roman troops became more reliant over time on the growing influence of the barbarian mercenaries known as foederati. Roman commanders in the field, although nominally working for Rome, became increasingly ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ionic Order
The Ionic order is one of the three canonic orders of classical architecture, the other two being the Doric and the Corinthian. There are two lesser orders: the Tuscan (a plainer Doric), and the rich variant of Corinthian called the composite order. Of the three classical canonic orders, the Corinthian order has the narrowest columns, followed by the Ionic order, with the Doric order having the widest columns. The Ionic capital is characterized by the use of volutes. The Ionic columns normally stand on a base which separates the shaft of the column from the stylobate or platform while the cap is usually enriched with egg-and-dart. The ancient architect and architectural historian Vitruvius associates the Ionic with feminine proportions (the Doric representing the masculine). Description Capital The major features of the Ionic order are the volutes of its capital, which have been the subject of much theoretical and practical discourse, based on a brief and obscure passage i ...

Corinthian Order
The Corinthian order (Greek: Κορινθιακός ρυθμός, Latin: ''Ordo Corinthius'') is the last developed of the three principal classical orders of Ancient Greek architecture and Roman architecture. The other two are the Doric order which was the earliest, followed by the Ionic order. In Ancient Greek architecture, the Corinthian order follows the Ionic in almost all respects other than the capitals of the columns. When classical architecture was revived during the Renaissance, two more orders were added to the canon: the Tuscan order and the Composite order. The Corinthian, with its offshoot the Composite, is the most ornate of the orders. This architectural style is characterized by slender fluted columns and elaborate capitals decorated with acanthus leaves and scrolls. There are many variations. The name ''Corinthian'' is derived from the ancient Greek city of Corinth, although the style had its own model in Roman practice, following precedents set by the Tem ...

Doric Order
The Doric order was one of the three orders of ancient Greek and later Roman architecture; the other two canonical orders were the Ionic and the Corinthian. The Doric is most easily recognized by the simple circular capitals at the top of columns. Originating in the western Doric region of Greece, it is the earliest and, in its essence, the simplest of the orders, though still with complex details in the entablature above. The Greek Doric column was fluted or smooth-surfaced, and had no base, dropping straight into the stylobate or platform on which the temple or other building stood. The capital was a simple circular form, with some mouldings, under a square cushion that is very wide in early versions, but later more restrained. Above a plain architrave, the complexity comes in the frieze, where the two features originally unique to the Doric, the triglyph and gutta, are skeuomorphic memories of the beams and retaining pegs of the wooden constructions that preceded stone Do ...

Classical Orders
An order in architecture is a certain assemblage of parts subject to uniform established proportions, regulated by the office that each part has to perform. Coming down to the present from Ancient Greek and Ancient Roman civilization, the architectural orders are the styles of classical architecture, each distinguished by its proportions and characteristic profiles and details, and most readily recognizable by the type of column employed. The three orders of architecture—the Doric, Ionic, and Corinthian—originated in Greece. To these the Romans added, in practice if not in name, the Tuscan, which they made simpler than Doric, and the Composite, which was more ornamental than the Corinthian. The architectural order of a classical building is akin to the mode or key of classical music; the grammar or rhetoric of a written composition. It is established by certain ''modules'' like the intervals of music, and it raises certain expectations in an audience attuned to its languag ...

Composite Order
The Composite order is a mixed order, combining the volutes of the Ionic order capital with the acanthus leaves of the Corinthian order.Henig, Martin (ed.), ''A Handbook of Roman Art'', p. 50, Phaidon, 1983, In many versions the composite order volutes are larger, however, and there is generally some ornament placed centrally between the volutes. The column of the composite order is typically ten diameters high, though as with all the orders these details may be adjusted by the architect for particular buildings. The Composite order is essentially treated as Corinthian except for the capital, with no consistent differences to that above or below the capital. The Composite order is not found in ancient Greek architecture and until the Renaissance was not ranked as a separate order. Instead it was considered as an imperial Roman form of the Corinthian order. Though the Arch of Titus, in the forum in Rome and built in 82 AD, is sometimes cited as the first prominent survivin ...

Tuscan Order
The Tuscan order (Latin ''Ordo Tuscanicus'' or ''Ordo Tuscanus'', with the meaning of Etruscan order) is one of the two classical orders developed by the Romans, the other being the composite order. It is influenced by the Doric order, but with un-fluted columns and a simpler entablature with no triglyphs or guttae. While relatively simple columns with round capitals had been part of the vernacular architecture of Italy and much of Europe since at least Etruscan architecture, the Romans did not consider this style to be a distinct architectural order (for example, the Roman architect Vitruvius did not include it alongside his descriptions of the Greek Doric, Ionic, and Corinthian orders). Its classification as a separate formal order is first mentioned in Isidore of Seville's ''Etymologies'' and refined during the Italian Renaissance. Sebastiano Serlio described five orders including a "Tuscan order", "the solidest and least ornate", in his fourth book of ''Regole generali di ...

Colonnade
In classical architecture, a colonnade is a long sequence of columns joined by their entablature, often free-standing, or part of a building. Paired or multiple pairs of columns are normally employed in a colonnade which can be straight or curved. The space enclosed may be covered or open. In St. Peter's Square in Rome, Bernini's great colonnade encloses a vast open elliptical space. When in front of a building, screening the door (Latin ''porta''), it is called a portico. When enclosing an open court, a peristyle. A portico may be more than one rank of columns deep, as at the Pantheon in Rome or the stoae of Ancient Greece. When the intercolumniation is alternately wide and narrow, a colonnade may be termed "araeosystyle" (Gr. αραιος, "widely spaced", and συστυλος, "with columns set close together"), as in the case of the western porch of St Paul's Cathedral and the east front of the Louvre.
