A Vault (French. voute, Italian. volta, German. Gewölbe, Polish. sklepienie) is an architectural term for an arched form used to provide a space with a ceiling or roof. The term architecture (from Greek αρχιτεκτονικήarchitektoniki) can be used to mean a process a profession or documentation An arch is a structure that spans a space while supporting weight (e [1] The parts of a vault exert a thrust that require a counter resistance. Thrust is a reaction force described quantitatively by Newton 's Second and Third Laws. Friction is the Force resisting the relative motion of two Surfaces in contact or a surface in contact with a fluid (e When vaults are built underground, the ground gives all the resistance required. However, when the vault is built above ground, various replacements are employed to supply the needed resistance. An example are the thicker walls used in the case of barrel or continuous vaults. A barrel vault, also known as a tunnel vault or a wagon vault, is an architectural element formed by the extrusion of a single curve (or pair of curves in the case Buttresses are used to supply resistance when intersecting vaults are employed. A buttress is an architectural structure built against (a counterfort) or projecting from a Wall which serves to support or reinforce the wall
The simplest kind of vault is the barrel vault (also called a wagon or tunnel vault) which is generally semicircular in shape. A barrel vault, also known as a tunnel vault or a wagon vault, is an architectural element formed by the extrusion of a single curve (or pair of curves in the case In Mathematics (more specifically Geometry) a semicircle is a two-dimensional Geometric shape that forms Half of a Circle. The barrel vault is a continuous arch, the length being greater than its diameter. As in building an arch, a temporary support is needed while rings of voussoirs are constructed and the rings placed in position. An arch is a structure that spans a space while supporting weight (e A voussoir is a wedge-shaped element typically a stone used in building an Arch. Until the topmost voussoir, the keystone, is positioned the vault is not self-supporting. A keystone is the architectural piece at the crown of a vault or Arch and marks its apex, locking the other pieces into position Where timber is easily obtained, this temporary support is provided by centering consisting of a framed truss with a semicircular or segmental head, which supports the voussoirs until the ring of the whole arch is completed.

Amongst the earliest known examples of any form of vaulting is to be found in the neolithic village of Khirokitia on Cyprus. The Neolithic (from Greek νεολιθικός — neolithikos from νέος neos, "new" + λίθος lithos Choirokoitia (sometimes spelled Khirokitia) (GreekΧοιροκοιτία is an Archaeological site on the island of Cyprus in the Mediterranean Cyprus (Κύπρος transliterated: Kýpros,; Kıbrıs officially the Republic of Cyprus (Κυπριακή Δημοκρατία Kypriakī́ Dīmokratía Dating from ca. 6000 BCE the circular buildings supported beehive shaped corbel domed vaults of unfired mud-bricks and also represent the first evidence for settlements with an upper floor.

Their construction differs from that at Khirokitia in that most appear partially buried and make provision for a dromos entry.
Domes however, represent a wider sense of the word vault. The distinction between the two is that a vault is essentially an arch which is extruded into the third dimension, whereas a dome is an arch revolved around its vertical axis.
Barrel vault
A barrel vault is the simplest form of a vault and resembles a barrel or tunnel cut lengthwise in half. The effect is that of a structure composed of continuous semicircular or pointed sections. [2] The earliest known examples of barrel vaults were built by the Sumerians, possibly under the ziggurat at Nippur in Babylonia,[3] which was built of fired bricks cemented with clay mortar. A barrel vault, also known as a tunnel vault or a wagon vault, is an architectural element formed by the extrusion of a single curve (or pair of curves in the case Sumer ( Sumerian: sux-Latn [[Ki (earth ki]]-[[EN (cuneiform en]]-'''ĝir15''', Akkadian: Šumeru; possibly Biblical Shinar A ziggurat ( Akkadian ziqqurrat, D-stem of zaqāru "to build on a raised area" was a Temple tower of the ancient Mesopotamian Nippur (URUENLIL; Sumerian: Nibru Akkadian: Nibbur) from the Sumerian for 'lord wind' (Enlil is modern ? in Afak Al Qadisyah Babylonia was an Amorite state in lower Mesopotamia (modern southern Iraq) with Babylon as its capital A brick is a block of Ceramic material used in Masonry construction laid using mortar.

The earliest barrel vaults in Egypt are thought to be those in the granaries built by Ramesses II, the ruins of which are behind the Ramesseum, at Thebes.

A similar system of construction was employed for the vault over the great hall at Ctesiphon, where the' material employed was fired bricks or tiles of great dimensions, cemented with mortar; but the span was close upon 83 ft.

It is probable that the great vaults of the Assyrian palaces were constructed in the same way, but with unburnt bricks dried only in the sun: one of the drains discovered by Sir Austen Henry Layard at Nimrud was built in rings sloping backwards.

From the fact that each Assyrian monarch on his accession to the throne commenced his reign by the erection of a palace, it is probable that, owing to the ephemeral construction of these great vaults, half a century was the term of their existence. This may also account for the fact that no domed structures exist of the type shown in one of the bas-reliefs from Nimrud; the tradition of their erection, however, would seem to have been handed down to their successors in Mesopotamia, viz.

A tile is a manufactured piece of hard-wearing material such as Ceramic, stone, metal or even Glass. to 10 in. , being generally square and about 4 to 2 in. thick, and they were not shaped as voussoirs, the connecting medium being thicker at the top than at the bottom. The earliest Egyptian examples of regular voussoirs in stone belong to the XXVIth Dynasty (ca. The creation of a reliable Chronology of Ancient Egypt is a task fraught with problems 650 B. C. ) in the additions made then to the temple of Medinet Habu, and here it is probable that centering of some kind was provided, as the vaults are built in rings, so that the same centering could be shifted on after the completion of each ring. Medinet Habu is the name commonly given to the Mortuary Temple of Ramesses III, an important New Kingdom period structure in the location The earliest example of regularly shaped voussoirs, and of about the same date, is found in the cloaca at Graviscae in Etruria, with a span of about 14 ft.

So far, all the vaults mentioned have been barrel vaults, which, when not built underground, required continuous walls of great thickness to resist their thrust; the earliest example of the next variety, the intersecting barrel vault, is said to be over a small hall at Pergamum, in Asia Minor, but its first employment over halls of great dimensions is due to the Romans. Anatolia (Anadolu Ανατολία Anatolía) or Asia minor, comprising most of modern Turkey, is the geographic region bounded by the Black Ancient Rome was a Civilization that grew out of a small agricultural community founded on the Italian Peninsula as early as the 10th century BC When two semicircular barrel vaults of the same diameter cross one another their intersection (a true ellipse) is known as a groin, down which the thrust of the vault is carried to the cross walls; if a series of two or more barrel vaults intersect one another, the weight is carried on to the piers at their intersection and the thrust is transmitted to the outer cross walls; thus in the Roman reservoir at Baiae, known as the Piscina Mirabilis, a series of five aisles with semicircular barrel vaults are intersected by twelve cross aisles, the vaults being carried on 48 piers and thick external walls. A groin vault or groined vault (also sometimes known as a double barrel vault or cross vault) is produced by the intersection at Baiae (in modern Italian only Baia) is a Frazione of the Comune of Bacoli, in the Campania region of Italy The Piscina Mirabilis was a freshwater cistern on the Miseno cliff at the western end of the Gulf of Naples, southern Italy. The width of these aisles being only about 13 ft. there was no great difficulty in the construction of these vaults, but in the Roman Baths of Caracalla the tepidarium had a span of 80 ft. The Baths of Caracalla were Roman public baths or Thermae, built in Rome between AD 212 and 216 during the reign of the Emperor Caracalla The tepidarium was the warm ( tepidus) bathroom of the Roman baths heated by a Hypocaust or Underfloor heating system , more than twice that of an English cathedral, so that its construction both from the statical and economical point of view was of the greatest importance. This article is about the history and organisation of the cathedral [4][8]
The researches of M. Choisy (L'Art de bâtir chez les Romains), based on a minute examination of those portions of the vaults which still remain in situ, have shown that, on a comparatively slight centering, consisting of trusses placed about 10 ft. apart and covered with planks laid from truss to truss, were laid - to begin with - two layers of the Roman brick (measuring nearly 2 ft. square and 2 in. thick); on these and on the trusses transverse rings of brick were built with longitudinal ties at intervals; on the brick layers and embedding the rings and cross ties concrete was thrown in horizontal layers, the haunches being filled in solid, and the surface sloped on either side and covered over with a tile roof of low pitch laid direct on the concrete. Concrete is a construction material composed of Cement (commonly Portland cement) as well as other cementitious materials such as Fly ash and Slag The rings relieved the centering from the weight imposed, and the two layers of bricks carried the concrete till it had set.
As the walls carrying these vaults were also built in concrete with occasional bond courses of brick, the whole structure was homogeneous. One of the important ingredients of the mortar was a volcanic deposit found near Rome, known as pozzolana, which, when the concrete had set, not only made the concrete as solid as the rock itself, but to a certain extent neutralized the thrust of the vaults, which formed shells equivalent to that of a metal lid; the Romans, however, do not seem to have recognized the extraordinary value of this pozzolana mixture, for they otherwise provided amply for the counteracting of any thrust which might exist by the erection of cross walls and buttresses. Deposition is the geological process by which material is added to a Landform or land mass Pozzolana, also known as pozzolanic ash is a fine sandy Volcanic ash, originally discovered and dug in Italy at Pozzuoli in the region around The M acro E xpansion T emplate A ttribute L anguage complements TAL, providing macros which allow the reuse of code across In the tepidaria of the Thermae and in the basilica of Constantine, in order to bring the thrust well within the walls, the main barrel vault of the hall was brought forward on each side and rested on detached columns, which constituted the principal architectural decoration.

The widest hall vaulted by the Romans was that of the throne room in the palace of Diocletian on the Palatine Hill, and this had the enormous span of 1oo ft. Gaius Aurelius Valerius Diocletianus ( ca. December 22 244 The modern historian Timothy Barnes takes December 22 as his birthdate The Palatine Hill ( Latin: Collis Palatium or Mons Palatinus) is the centermost of the Seven Hills of Rome , its thrust being counteracted by other halls on either side with buttresses outside. In provincial towns and in other parts of the Roman Empire, where the material pozzolana was not procurable, the Romans had to trust to their mortar as a cementing medium, but this, though excellent of its kind, was not of sufficient cohesive strength to allow of the erection of vaults of more than about 40 ft. span, which were generally built in rubble masonry. Masonry is the building of structures from individual units laid in and bound together by mortar, and the term "masonry" can also refer to the units themselves There still exist in Asia Minor and Syria some vaulted halls, generally attached to thermae, which are carried on walls of great thickness. Syria ( سوريّة or) officially the Syrian Arab Republic (Arabic ar الجمهورية العربية السورية There were many varieties of the Roman vault, whether continuous or intersected, such as those employed over the corridors on the Colosseum and the theatre of Marcellus, but in these cases the springing of the vault was above the summit of the arches of the main front, so that there was no intersection; on the other hand, over the corridors were either elliptical or semicircular, or over the staircases rising vaults, all of which were more difficult to construct; there were also numerous solutions of vault over circular halls, of which that of the Pantheon was the most important example, having a diameter of 142 ft. The Colosseum or Roman Coliseum, originally the Flavian Amphitheatre ( Latin: Amphitheatrum Flavium, Italian Anfiteatro Flavio The Theatre of Marcellus (Latin Theatrum Marcelli; Italian Teatro di Marcello) is an ancient theatre built at the beginning of the Roman Empire.

Reference has been made to the twisting of the groins in Roman work, where the intersecting barrel vaults were not of the same diameter; their construction must at all times have been somewhat difficult, but where the barrel vaulting was carried round over the choir aisle and was intersected, as in St Bartholomew's, Smithfield, by semicones, instead of cylinders, it became worse and the groins more complicated; this would seem to have led to a change of system, and to the introduction of a new feature, which completely revolutionized the construction of the vault.

A choir, chorale, or chorus is a Musical ensemble of Singers An aisle is in general a space for walking with rows of seats on either side or with rows of seats on one side and a wall on the other Hitherto the intersecting features were geometrical surfaces, of which the diagonal groins were the intersections, elliptical in form, generally weak in construction and often twisting (Plate I. fig. 13). The medieval builder reversed the process, and set up the diagonal ribs first, which were utilized as permanent centres, and on these he carried his vault or web, which henceforward took its shape from the ribs. WEB is a Computer programming system created by Donald E Knuth as the first implementation of what he called " Literate programming " the Instead of the elliptical curve which was given by the intersection of two semicircular barrel vaults, or cylinders, he employed the semicircular arch for the diagonal ribs; this, however, raised the centre of the square bay vaulted above the level of the transverse arches and of the wall ribs, and thus gave the appearance of a dome to the vault, such as may be seen in the nave of Sant' Ambrogio, Milan. Milan (Milano Milan (listen) is one of the largest cities in Italy, located in the plains of Lombardy. To meet this, at first the transverse and wall ribs were stilted, or the upper part of their arches was raised, as in the Abbaye-aux-Hommes at Caen, and the Abbey of Lessay, in Normandy. The Abbaye aux Hommes ("Men's Abbey" is a former Abbey church in the French city of Caen. Caen (kɑ̃ is a commune in northwestern France. It is the Prefecture of the Calvados department and the capital of the Normandy (Normandie Norman: Normaundie) is a geographical region corresponding to the former Duchy of Normandy. The problem was ultimately solved by the introduction of the pointed arch for the transverse and wall ribs - the pointed arch had long been known and employed, on account of its much greater strength and of the less thrust it exerted on the walls. When employed for the ribs of a vault, however narrow the span might be, by adopting a pointed arch, its summit could be made to range in height with the diagonal rib; and, moreover, when utilized for the ribs of the annular vault, as in the aisle round the apsidal termination of the choir, it was not necessary that the half ribs on the outer side should be in the same plane as those of the inner side; for when the opposite ribs met in the centre of the annular vault, the thrust was equally transmitted from one to the other, and being already a broken arch the change of its direction was not noticeable. In Vertebrate Anatomy, ribs ( Latin costae) are the long curved Bones which form the ribcage. A barrel vault, also known as a tunnel vault or a wagon vault, is an architectural element formed by the extrusion of a single curve (or pair of curves in the case APSE standing for Ada Programming Support Environment is a program or set of programs to support Software development in the Ada programming language.
The first introduction of the pointed arch rib took place at Durham Cathedral and pre-dated the abbey of St. Denis. The Cathedral Church of Christ Blessed Mary the Virgin and St Cuthbert of Durham, commonly referred to as Durham Cathedral, in the city of Durham, England Saint Denis (also called Dionysius, Dennis, or Denys) is a Christian martyr and Saint. Whilst the pointed rib-arch is often seen as an identifier for gothic architecture, Durham is a romanesque cathedral whose masons experimented with the possibility of rib-arches before it was widely adopted by western church architecture. [9] It was in the church at Vezelay (1140) that it was extended to the square bay of the porch. Vézelay is a commune in the Yonne département in the Bourgogne région of France. A porch is a structure attached to a building forming a covered entrance to a vestibule or doorway Before entering into the question of the web or stone shell of the vault carried on the ribs, the earlier development of the great vaults which were thrown over the naves of a cathedral, or church, before the introduction of the pointed arch rib, shall here be noted. As has been pointed out, the aisles had already in the early Christian churches been covered over with groined vaults, the only advance made in the later developments being the introduction of transverse ribs' dividing the bays into square compartments; but when in the 12th century[10] the first attempts were made to vault over the naves, another difficulty presented itself, because the latter were twice the width of the aisles, so that it became necessary to include two bays of the aisles to form one square bay in the nave. This was an immense space to vault over, and moreover, it followed that every alternate pier served no purpose, so far as the support of the nave vault was concerned, and this would seem to have suggested an alternative, viz. A pier is a raised Walkway over water supported by widely spread Piles or pillars. to provide a supplementary rib across the church and between the transverse ribs. This resulted in what is known as a sexpartite, or six-celled vault, of which one of the earliest examples is found in the Abbaye-aux-Hommes (S. Etienne) at Caen. Caen (kɑ̃ is a commune in northwestern France. It is the Prefecture of the Calvados department and the capital of the This church, built by William the Conqueror, was originally constructed to carry a timber roof only, but nearly a century later the upper part of the nave walls were partly rebuilt, in order that it might be covered with a vault. The immense size, however, of the square vault over the nave necessitated some additional support, so that an intermediate rib was thrown across the church, dividing the square compartment into six cells, and called the sexpartite vault this was adopted in the cathedrals of Sens (1170), Laon (1195), Noyon (1190), Paris (1223-35), and Bourges (1250). Sexpartite vault, in Architecture, is a rib vault divided into six bays by two diagonal ribs and three transerse ribs History Caesar mentions Agedincum in the territory of the Senones several times in his Commentarii de Bello Gallico, and the city retains Laon (lɑ̃ is a city and commune in Picardie in northern France, préfecture (capital} of the Aisne department For another meaning see Noyan Noyon ( Latin: Noviomagus Veromanduorum) is a small (14471 inhabitants in 1990 but historic Bourges is a commune in central France on the Yèvre river It is the capital of the department of Cher and also was the capital The intermediate rib, however, had the disadvantage of partially obscuring one side of the clerestory windows, and it threw unequal weights on the alternate piers, so that in the cathedral of Soissons (1205) a quadripartite (fig. Clerestory (ˈklɪə(rstɔəri lit clear storey, also clearstory, clearstorey, or overstorey) is an architectural term denoting Soissons is a commune in the Aisne department in Picardie in northern France, located on the Aisne River, about 100 8) or four-celled vault was introduced, the width of each bay being half the span of the nave, and corresponding therefore with the aisle piers. To this there are some exceptions, in Sant' Ambrogio, Milan, and San Michele, Pavia (the original vault), and in the cathedrals of Spires, Mainz and Worms, where the quadripartite vaults are nearly square, the intermediate piers of the aisles being of much smaller dimensions. Pavia (pronounced Pavìa,) the ancient Ticinum, is a town and Comune of south-western Lombardy, northern Italy, 35 km south Mainz Cathedral, formally known in English as St Martin Cathedral (in German Mainzer Dom, sometimes Der Hohe Dom zu Mainz) is located Cathedral of St Peter (German Wormser Dom) is the principal church and chief building of Worms, Germany.

In the earlier stage of rib vaulting, the arched ribs consisted of independent or separate voussoirs down to the springing; the difficulty, however, of working the ribs separately led to two other important changes: (I) the lower part of the transverse diagonal and wall ribs were all worked out of one stone; and (2) the lower horizontal, constituting what is known as the [[tas-de-charge (q. v. ) or solid springer. A springer is an architectural term for the lowest Voussoir on each side of an Arch. Fig. 9 is a diagram made by Professor Willis taken from the south transept of Westminster Abbey. The horizontal courses rise to N. or about half the height of the vault, but the ribs are freed from one another from the point M. The tas-de-charge, or solid springer, had two advantages: (1) it enabled the stone courses to run straight through the wall, so as to bond the whole together much better; and (2) it lessened the span of the vault, which then required a centering of smaller dimensions. As soon as the ribs were completed, the web or stone shell of the vault was laid on them. In some English work, as may be seen in fig. 9, each course of stone was of uniform height from one side to the other; but, as the diagonal rib was longer than either the transverse or wall rib, the courses dipped towards the former, and at the apex of the vault were cut to fit one another. At an early period, in consequence of the great span of the vault and the very slight rise or curvature of the web, it was thought better to simplify the construction of the web by introducing intermediate ribs between the wall rib and the diagonal rib and between the diagonal and the transverse ribs; and in order to meet the thrust of these intermediate ribs a ridge rib was required, and the prolongation of this rib to the wall rib hid the junction of the web at the summit, which was not always very sightly, and constituted the ridge rib. In France, on the other hand, the web courses were always laid horizontally, and they are therefore of unequal height, increasing towards the diagonal rib. Each course also was given a slight rise in the centre, so as to increase its strength; this enabled the French masons to dispense with the intermediate rib, which was not introduced by them till the 15th century, and then more as a decorative than a constructive feature, as the domical form given to the French web rendered unnecessary the ridge rib, which, with some few exceptions, exists only in England. In both English and French vaulting centering was rarely required for the building of the web, a template (Fr. cerce) being employed to support the stones of each ring until it was complete. In Italy, Germany and Spain the French method of building the web was adopted, with horizontal courses and a domical form. Italy (Italia officially the Italian Republic, (Repubblica Italiana is located on the Italian Peninsula in Southern Europe, and on the two largest Germany, officially the Federal Republic of Germany ( ˈbʊndəsʁepuˌbliːk ˈdɔʏtʃlant is a Country in Central Europe. Spain () or the Kingdom of Spain (Reino de España is a country located mostly in southwestern Europe on the Iberian Peninsula. Sometimes, in the case of comparatively narrow compartments, and more especially in clerestories, the wall rib was stilted, and this caused a peculiar twisting of the web, as may be seen in fig. Clerestory (ˈklɪə(rstɔəri lit clear storey, also clearstory, clearstorey, or overstorey) is an architectural term denoting 9, where the springing of the wall rib is at K: to these twisted surfaces the term ploughshare vaulting is given. The intersection of two or three Barrel vaults produces a rib-vault or ribbed vault when they are edged with piped masonry often carved in decorative patterns
One of the earliest examples of the introduction of the intermediate rib is found in the nave of Lincoln Cathedral, and there the ridge rib is not carried to the wall rib. It was soon found, however, that the construction of the web was much facilitated by additional ribs, and consequently there was a tendency to increase their number, so that in the nave of Exeter Cathedral three intermediate ribs were provided between the wall rib and the diagonal rib. Exeter ( (IPA ˈeksɪtər is a city, district and County town of Devon, England. In order to mask the junction of the various ribs, their intersections were ornamented with richly carved bosses, and this practice increased on the introduction of another short rib, known as the lierne, a term in France given to the ridge rib. Lierne ribs in English vaults are short ribs crossing between the main ribs, and were employed chiefly as decorative features, as, for instance, in the stellar vault (see Plate I. A Lierne (from the French lier - to bind in Gothic Rib vaulting is an architectural term for a tertiary rib spanning between two other ribs instead of fig. 16), one of the best examples of which exists in the vault of the oriel window of Crosby Hall, London. Oriel windows are a form of Bay window commonly found in Gothic revival Architecture, which jut out from the main wall of the building but do not reach The tendency to increase the number of ribs led to singular results in some cases, as in the choir of Gloucester Cathedral (see Plate II. Gloucester Cathedral, or the Cathedral Church of St Peter and the Holy and Undivided Trinity, in Gloucester, England, stands in the north of the city fig. 17), where the ordinary diagonal ribs become mere ornamental mouldings on the surface of an intersected pointed barrel vault, and again in the cloisters, where the introduction of the fan vault, forming a concave-sided conoid, returned to the principles of the Roman geometrical vault. A fan vault is a form of vault used in the Perpendicular Gothic style in which the ribs are all of the same curve and spaced equidistantly in a manner resembling The Conoid Ligament, the posterior and medial fasciculus is a dense band of fibers conical in form with its base directed upward This is further shown in the construction of these fan vaults, for although in the earliest examples each of the ribs above the tas-de-charge was an independent feature, eventually it was found easier to carve them and the web out of the solid stone, so that the rib and web were purely decorative and had no constructional or independent functions.
Fan vault
The fan vault would seem to have owed its origin to the employment of centerings of one curve for all the ribs, instead of having separate centerings for the transverse, diagonal wall and intermediate ribs; it was facilitated also by the introduction of the four-centred arch, because the lower portion of the arch formed part of the fan, or conoid, and the upper part could be extended at pleasure with a greater radius across the vault. A fan vault is a form of vault used in the Perpendicular Gothic style in which the ribs are all of the same curve and spaced equidistantly in a manner resembling The simplest version is that found in the cloisters of Gloucester Cathedral, where the fans meet one another at the summit, so that there are only small compartments between the fans to be filled up. In later examples, as in King's College Chapel, Cambridge (see Plate II. King's College Chapel is the chapel to King's College of the University of Cambridge, and is one of the finest examples of late English Gothic fig. 18), on account of the great dimensions of the vault, it was found necessary to introduce transverse ribs, which were required to give greater strength. Similar transverse ribs are found in Henry VII's chapel (see Plate II. fig. 19) and in the divinity schools at Oxford, where a new development presented itself. A divinity school is an Institute of Higher education devoted to the study of divinity, religion and Theology. Oxford is currently bidding for the 2010 Wikimania Conference Oxford () is a city, and the County town of Oxfordshire, One of the defects of the fan vault at Gloucester is the appearance it gives of being half sunk in the wall; to remedy this, in the two buildings just quoted, the complete conoid is detached and treated as a pendant. A pendant (from Old French) is a hanging object generally attached to a Necklace or an Earring.
Byzantine vaults and domes
The vault of the Basilica of Maxentius, completed by Constantine, was the last great work carried out by the Romans, and two centuries pass before the next important development is found in the Church of the Holy Wisdom (Hagia Sophia) at Constantinople. The Basilica of Maxentius and Constantine (sometimes known as the Basilica Nova 'new Basilica ' or Basilica Maxentius) was the largest building in Hagia Sophia (Ayasofya Αγία Σοφία " Holy Wisdom " Sancta Sophia or Sancta Sapientia) is a former patriarchal Basilica, later Constantinople (Κωνσταντινούπολις Konstantinoúpolis, or gr ἡ Πόλις hē Polis, Latin: la CONSTANTINOPOLIS It is probable that the realization of the great advance in the science of vaulting shown in this church owed something to the eastern tradition of dome vaulting seen in the Assyrian domes, which are known to us only by the representations in the bas-relief from Nimrud (fig. A dome is a common structural element of Architecture that resembles the hollow upper half of a Sphere. 1), because in the great water cisterns in Istanbul, known as the Yeri Batan Serai (the underground palace) and Bin bir-derek (cistern with a thousand and one columns), both built by Constantine, we find the intersecting groin vaults of the Romans already replaced by small cupolas or domes. These domes, however, are of small dimensions when compared with that projected and carried out by Justinian in the Hagia Sophia. Flavius Petrus Sabbatius Iustinianus ( Greek: Φλάβιος Πέτρος Σαββάτιος Ιουστινιανός; known in English as Justinian I or Hagia Sophia (Ayasofya Αγία Σοφία " Holy Wisdom " Sancta Sophia or Sancta Sapientia) is a former patriarchal Basilica, later Previous to this the greatest dome was that of the Pantheon at Rome, but this was carried on an immense wall 20 ft. The Pantheon ( Latin Pantheon, from Greek Πάνθειον Pantheon, meaning "Temple of all the gods" is a building in Rome thick, and with the exception of small niches or recesses in the thickness of the wall could not be extended, so that Justinian apparently instructed his architect to provide an immense hemicycle or apse at the eastern end, a similar apse at the western end, and great arches on either side, the walls under which would be pierced with windows. In Mathematics (more specifically Geometry) a semicircle is a two-dimensional Geometric shape that forms Half of a Circle. APSE standing for Ada Programming Support Environment is a program or set of programs to support Software development in the Ada programming language. Unlike the Pantheon dome, the upper portions of which were made of concrete, Byzantine domes were made of brick, which were lighter and thinner, but which more vulnerable to the forces exterted onto them.

A diagram is a 2D geometric symbolic Representation of Information according to some Visualization technique 4) shows the outlines of the solution of the problem. If a hemispherical dome is cut by four vertical planes, the intersection gives four semicircular arches; if cut in addition by a horizontal plane tangent to the top of these arches, it describes a circle; that portion of the sphere which is below this circle and between the arches, forming a spherical spandril, is the pendentive (fig. A spandrel (less often spandril or splaundrel) is the space between two Arches or between an arch and a rectangular enclosure A pendentive is a constructive device permitting the placing of a circular Dome over a square room or an elliptical Dome over a rectangular room 5), and its radius is equal to the diagonal of the square on which the four arches rest. Remote Authentication Dial In User Service ( RADIUS) is a networking protocol that provides centralized access authorization and accounting management for people or computers A diagonal can refer to a line joining two nonconsecutive vertices of a Polygon or Polyhedron, or in contexts any upward or downward sloping line Having obtained a circle for the base of the dome, it is not necessary that the upper portion of the dome should spring from the same level as the arches, or that its domical surface should be a continuation of that of the pendentive. The first and second dome of the Hagia Sophia apparently fell down, so that Justinian determined to raise it, possibly to give greater lightness to the structure, but mainly in order to obtain increased light for the interior of the church. This was effected by piercing it with forty windows - the effect of which was of an extraordinary nature, as the light streaming through these windows gave to the dome the appearance of being suspended in the air. The pendentive which carried the dome rested on four great arches, the thrust of those crossing the church being counteracted by immense buttresses which traversed the aisles, and the other two partly by smaller arches in the apse, the thrust being carried to the outer walls, and to a certain extent by the side walls which were built under the arches. From the description given by Procopius we gather that the centering employed for the great arches consisted of a wall erected to support them during their erection. Procopius of Caesarea ( Προκόπιος ο Καισαρεύς, c The construction of the pendentives is not known, but it is surmised that to the top of the pendentives they were built in horizontal courses of brick, projecting one over the other, the projecting angles being cut off afterwards and covered with stucco in which the mosaics were embedded; this was the method employed in the erection of the Perigordian domes, to which we shall return; these, however, were of less diameter than those of the Hagia Sophia, being only about 40 to 60 ft. instead of 107 ft. The apotheosis of Byzantine architecture, in fact, was reached in Hagia Sophia, for although it formed the model on which all subsequent Byzantine churches were based, so far as their plan was concerned, no domes approaching the former in dimensions were even attempted. Byzantine architecture is the Architecture of the Byzantine Empire. The principal difference in some later examples is that which took place in the form of the pendentive on which the dome was carried. Instead of the spherical spandril of Hagia Sophia, large niches were formed in the angles, as in the Mosque of Damascus, which was built by Byzantine workmen for the Al-Walid I in A. The Grand Mosque of Damascus, also known as the Ummayad Mosque' ( Arabic: جامع بني أمية الكبير transl Al-Walid ibn Abd al-Malik ( الوليد بن عبد الملك or Al-Walid I (668 - 715 was a wise and powerful Umayyad Caliph who ruled from 705 D. 705; these gave an octagonal base on which the hemispherical dome rested (fig. 6); or again, as in the Sassanian palaces of Serbia and Firouzabad of the 4th and 5th century, when a series of concentric arch rings, projecting one in front of the other, were built, giving also an octagonal base; each of these pendentives is known as a squinch. A squinch in architecture is a piece of construction used for filling in the upper angles of a square room so as to form a proper base to receive an Octagonal or spherical
There is one other remarkable vault, also built by Justinian, in the Church of the Saints Sergius and Bacchus in Constantinople. Little Hagia Sophia ( Küçuk Ayasofya Camii) formerly the Church of the Saints Sergius and Bacchus ( Greek:) is a former Eastern Orthodox The central area of this church was octagonal on plan, and the dome is divided into sixteen compartments; of these eight consist of broad flat bands rising from the centre of each of the walls, and the alternate eight are concave cells over the angles of the octagon, which externally and internally give to the roof the appearance of an umbrella.
Romanesque
Although the dome constitutes the principal characteristic of the Byzantine church, throughout Asia Minor are numerous examples in which the naves are vaulted with the semicircular barrel vault, and this is the type of vault found throughout the south of France in the 11th and 12th centuries, the only change being the occasional substitution of the pointed barrel vault, adopted not only on account of its exerting a less thrust, but because, as pointed out by Fergusson (vol. ii. p. 46), the roofing tiles were laid directly on the vault and a less amount of filling in at the top was required. The continuous thrust of the barrel vault in these cases was met either by semicircular or pointed barrel vaults on the aisles, which had only half the span of the nave; of this there is an interesting example in the Chapel of Saint John in the Tower of London - and sometimes by half-barrel vaults. In Romanesque and Gothic Christian Abbey, Cathedral Basilica and church Architecture, the nave is the St John's Chapel, or the Chapel of St John the Evangelist, is located in the Tower of London. Her Majesty's Royal Palace and Fortress, more commonly known as the Tower of London (and historically as The Tower) is a historic monument in central London The great thickness of the walls, however, required in such constructions would seem to have led to another solution of the problem of roofing over churches with incombustible material, viz. that which is found throughout Perigord and La Charente, where a series of domes carried on pendentives covered over the nave, the chief peculiarities of these domes being the fact that the arches carrying them form part of the pendentives, which are all built in horizontal courses. The Périgord ( ( Occitan: Peiregòrd / Perigòrd) is a former province of France, which corresponds roughly to the current Dordogne
The intersecting and groined vault of the Romans was employed in the early Christian churches in Rome, but only over the aisles, which were comparatively of small span, but in these there was a tendency to raise the centres of these vaults, which became slightly domical; in all these cases centering was employed.
Gothic survival and the renaissance
One of the most interesting examples of the fan vault is that over the staircase leading to the hall of Christ Church, Oxford, and here the complete conoid is displayed in its centre carried on a central column. Not to be confused with Christchurch, a city in New Zealand. Christ Church (Ædes Christi the temple or house of Christ and thus sometimes known as This vault, not built until 1640, is an exceptional example of the long continuance of traditional workmanship, probably in Oxford transmitted in consequence of the late vaulting of the entrance gateways to the colleges. Fan vaulting is peculiar to England, the only example approaching it in France being the pendant of the Lady-chapel at Caudebec, in Normandy. A Lady chapel is a traditional English term for a Chapel inside a Cathedral or large church dedicated to the Blessed Virgin Mary. In France, Germany and Spain the multiplication of ribs in the 15th century led to decorative vaults of various kinds, but with some singular modifications. Thus in Germany, recognizing that the rib was no longer a necessary constructive feature, they cut it off abruptly, leaving a stump only; in France, on the other hand, they gave still more importance to the rib, by making it of greater depth, piercing it with tracery and hanging pendants from it, and the web became a horizontal stone paving laid on the top of these decorated vertical webs. Tracery is a series of intersecting ribs used in Gothic architecture, especially windows and in the Perpendicular Gothic style vaulting. This is the characteristic of the great Renaissance work in France and Spain; but it soon gave way to Italian influence, when the construction of vaults reverted to the geometrical surfaces of the Romans, without, however, always that economy in centering to which they had attached so much importance, and more especially in small structures. The Culture of Italy can be found in the Roman ruins remaining in much of the country the precepts of the Roman Catholic Church, the spirit of the In large vaults, where it constituted an important expense, the chief boast of some of the most eminent architects has been that centering was dispensed with, as in the case of the dome of the Santa Maria del Fiore in Florence, built by Filippo Brunelleschi, and Ferguson cites as an example the great dome of the church at Mousta in Malta, erected in the first half of the 19th century, which was built entirely without centering of any kind. The Basilica di Santa Maria del Fiore is the Cathedral church ( Duomo) of Florence, Italy. Florence ( Italian: Firenze Florentia and Fiorenza) is the Capital City of the Italian region of Tuscany Filippo Brunelleschi (1377 – April 15, 1446) was one of the foremost architects and engineers of the Italian Renaissance.

Vaulting and Faux Vaulting in the Renaissance and After
It is important to note that whereas Roman vaults, like that of the Pantheon, and Byzantine vaults, like that at Hagia Sophia, were not protected from above (i. The Pantheon ( Latin Pantheon, from Greek Πάνθειον Pantheon, meaning "Temple of all the gods" is a building in Rome Hagia Sophia (Ayasofya Αγία Σοφία " Holy Wisdom " Sancta Sophia or Sancta Sapientia) is a former patriarchal Basilica, later e. the vault from the inside was the same that one saw from the outside), the European architects of the Middle Ages, protected their vaults with wooden roofs. In other words, one will not see a Gothic vault from the outside. The reasons for this development are hypothetical, but the fact that the roofed basilica form preceded the era when vaults begin to be made is certainly to be taken into consideration. The Latin word basilica (derived from Greek, Basiliké Stoà, Royal Stoa) was originally used to describe a Roman In other words, the traditional image of a roof took precedent over the vault.
The separation between interior and exterior - and between structure and image - was to be developed very purposefully in the Renaissance and beyond, especially once the dome became reinstated in the Western tradition as a key element in church design. The Renaissance (from French Renaissance, meaning "rebirth" Italian: Rinascimento, from re- "again" and nascere A dome is a common structural element of Architecture that resembles the hollow upper half of a Sphere. Michelangelo’s dome for St. Peter’s Basilica in Rome, as redesigned between 1585 and 1590 by Giacomo della Porta, for example, consists of two domes of which, however, only the inner is structural. Michelangelo di Lodovico Buonarroti Simoni Two biographies were published of him during his lifetime One of them by Giorgio Vasari, proposed that he was the pinnacle of all The Basilica of Saint Peter (Basilica Sancti Petri officially known in Italian as the Basilica di San Pietro in Vaticano and commonly known as St Rome ( Roma ˈroma Roma is the capital city of Italy and Lazio, and is Italy's largest and most populous city with more than 2 Giacomo della Porta (c 1533 &ndash 1602 was an Italian architect and sculptor who worked for many important buildings in Rome including St Baltasar Neumann, in his baroque churches, perfected light-weight plaster vaults supported by wooden frames.

In St Paul's Cathedral in London there is a highly complex system of vaults and faux-vaults. St Paul's Cathedral, is the Anglican Cathedral on Ludgate Hill, in the City of London, and the seat of the Bishop of London. London ( ˈlʌndən is the capital and largest urban area in the United Kingdom. [12] The dome that one sees from the outside is not a vault, but a relatively light-weight wooden-framed structure resting on an invisible - and for its age highly original - catenary vault of brick, below which is another dome, (the dome that one sees from the inside), but of plaster supported by a wood frame. From the inside, one can easily assume that that one is looking at the same vault that one sees from the outside.
India
There are two other ribbed vaults in India which form no part of the development of European vaults, but are too remarkable to be passed over; one carries the central dome of the Jumma Musjid at Bijapur (A. Urdu ( ur '''{{Nastaliq اردو}}''' trans Urdū, historically spelled Ordu) is a Central Indo-Aryan language Urdu is a standardised India, officially the Republic of India (भारत गणराज्य inc-Latn Bhārat Gaṇarājya; see also other Indian languages) is a country Bijapur (ವಿಜಾಪುರ Vijapur is a district headquarters of the Bijapur District in the state of Karnataka.

Gol Gumbaz (ಗೋಲ ಗುಮ್ಮಟ is the Mausoleum of Mohammed Adil Shah ( 1627 - 57) of the Adil Shahi dynasty of Indian D. 1626-1660) in the same town. The vault of the latter was constructed over a hall 135 ft. square, to carry a hemispherical dome. The ribs, instead of being carried across the angles only, thus giving an octagonal base for the dome, are carried across to the further pier of the octagon (fig. 12) and consequently intersect one another, reducing the central opening to 97 ft. in diameter, and, by the weight of the masonry they carry, serving as counterpoise to the thrust of the dome, which is set back so as to leave a passage about 12 ft. wide round the interior. The internal diameter of the dome is 124 ft. , its height 175 ft. and the ribs struck from four centres have their springing 57 ft. from the floor of the hall. The Jumma Musjid dome was of smaller dimensions, on a square of 70 ft. with a diameter of 57 ft. , and was carried on piers only instead of immensely thick walls as in the tomb; but any thrust which might exist was counteracted by its transmission across aisles to the outer wall.

In Mathematics, a paraboloid is a Quadric surface of special kind Reinforced concrete is Concrete in which reinforcement bars (" Rebars quot or fibers have been incorporated to strengthen a material that would otherwise be The advent of shell construction and the better mathematical understanding of hyperbolic paraboloids allowed very thin, strong vaults to be constructed with previously unseen shapes.
