An arch bridge is a bridge with abutments at each end shaped as a curved arch . Arch bridges work by transferring the weight of the bridge and its loads partially into a horizontal thrust restrained by the abutments at either side, and partially into a vertical load on the arch supports. A viaduct (a long bridge) may be made from a series of arches, although other more economical structures are typically used today.
96-591: The Krämerbrücke ( pronounced [ˈkʁɛːmɐˌbʁʏkə] ; Merchants' bridge) is a medieval arch bridge in the city of Erfurt , in Thuringia , central Germany, which is lined with half-timbered shops and houses on both sides of a cobblestone street. It is one of the few remaining bridges in the world that have inhabited buildings. It has been continuously inhabited for over 500 years, longer than any other bridge in Europe. The stone, pedestrian bridge, which dates from 1325,
192-520: A Country Path," Martin Heidegger develops his concept of Gelassenheit, or releasement, from Meister Eckhart. Ian Moore argues "that Heidegger consulted Eckhart again and again throughout his career to develop or support his own thought.". The French philosopher Jacques Derrida distinguishes Eckhart's Negative Theology from his own concept of différance although John D. Caputo in his influential The Tears and Prayers of Jacques Derrida emphasises
288-479: A correspondent of Radcliffe, wrote in a defence of Eckhart to Cardinal Ratzinger (later Pope Benedict XVI ), stating: Only 28 propositions were censured, but they were taken out of their context and impossible to verify, since there were no manuscripts in Avignon. Eckhart was schooled in medieval scholasticism and was well-acquainted with Aristotelianism and Augustinianism . The Neo-Platonism of Pseudo-Dionysius
384-505: A deck arch bridge. Any part supported from arch below may have spandrels that are closed or open. The Sydney Harbour Bridge and the Bayonne Bridge are a through arch bridge which uses a truss type arch. Also known as a bowstring arch, this type of arch bridge incorporates a tie between two opposite ends of the arch. The tie is usually the deck and is capable of withstanding the horizontal thrust forces which would normally be exerted on
480-653: A full understanding of Eckhart. In 1923, Eckhart's Essential Sermons, Commentaries, Treatises and Defense (also known as the Rechtsfertigung , or "vindicatory document") was re-published. The Defense recorded Eckhart's responses against two of the Inquisitional proceedings brought against him at Cologne, and details of the circumstances of Eckhart's trial. The excerpts in the Defense from vernacular sermons and treatises described by Eckhart as his own, served to authenticate
576-458: A greater passage for flood waters. Bridges with perforated spandrels can be found worldwide, such as in China ( Zhaozhou Bridge , 7th century). Greece ( Bridge of Arta , 17th century) and Wales ( Cenarth Bridge , 18th century). In more modern times, stone and brick arches continued to be built by many civil engineers, including Thomas Telford , Isambard Kingdom Brunel and John Rennie . A key pioneer
672-645: A guide to the spiritual life like St Bonaventure’s Itinerarium – the Journey of the Soul," but that his ideas on this have to be condensed from his "couple of very short books on suffering and detachment" and sermons. According to Mills, Eckhart's comments on prayer are only about contemplative prayer and "detachment." According to Reiner Schürmann, four stages can be discerned in Eckhart's understanding mystical development: dissimilarity, similarity, identity, breakthrough. Eckhart
768-413: A man should be empty of self and all things; and secondly, that he should be reconstructed in the simple good that God is; and thirdly, that he should consider the great aristocracy which God has set up in the soul, such that by means of it man may wonderfully attain to God; and fourthly, of the purity of the divine nature. As Eckhart said in his trial defence, his sermons were meant to inspire in listeners
864-402: A man who has wine in his cellar but has never tasted it, he does not know that it is good. (Sermon 10, DW I 164.5–8) Whoever does not understand what I say, let him not burden his heart with it. For as long as a man is not like this truth, he will not understand what I say. For this is a truth beyond thought that comes immediately from the heart of God. (Sermon 52, DW II 506.1–3) Kurt Flasch ,
960-607: A medieval trade and pilgrims' road network, which linked Rome with the Baltic Sea, and Moscow with Santiago de Compostela in northern Spain. The Krämerbrücke is on the route from the river Rhine to Silesia . It is also on one of the main routes of the Camino de Santiago , the Way of St. James pilgrimage. Erfurt was at a major crossroads of the Via Regia and it became an important trading centre in
1056-471: A member of the so-called Bochum-school of mediaeval philosophy, strongly reacted against the influence of New Age mysticism and "all kinds of emotional subjective mysticism", arguing for the need to free Eckhart from "the Mystical Flood". He sees Eckhart strictly as a philosopher. Flasch argues that the opposition between "mystic" and "scholastic" is not relevant because this mysticism (in Eckhart's context)

#17328518710171152-511: A misinterpretation of the archives of the period. In reality, little is known about his family and early life. There is no basis for giving him the Christian name of Johannes , which sometimes appears in biographical sketches: his Christian name was Eckhart ; his surname was von Hochheim . Probably around 1278, Eckhart joined the Dominican convent at Erfurt , when he was about eighteen. It
1248-435: A number of sermons found in old editions of Johann Tauler 's sermons, published by Kachelouen (Leipzig, 1498) and by Adam Petri (Basel, 1521 and 1522). Interest in Eckhart's works was revived in the early nineteenth century, especially by German Romantics and Idealist philosophers. Franz Pfeiffer 's publication in 1857 of Eckhart's German sermons and treatises added greatly to this interest. Another important figure in
1344-501: A number of the vernacular works. Although questions remain about the authenticity of some vernacular works, there is no dispute about the genuine character of the Latin texts presented in the critical edition. Since the 1960s scholars have debated whether Eckhart should be called a "mystic". The philosopher Karl Albert had already argued that Eckhart had to be placed in the tradition of philosophical mysticism of Parmenides and Plato and
1440-448: A quantity of fill material (typically compacted rubble) above the arch in order to increase this dead-weight on the bridge and prevent tension from occurring in the arch ring as loads move across the bridge. Other materials that were used to build this type of bridge were brick and unreinforced concrete. When masonry (cut stone) is used the angles of the faces are cut to minimize shear forces. Where random masonry (uncut and unprepared stones)
1536-415: A result, masonry arch bridges are designed to be constantly under compression, so far as is possible. Each arch is constructed over a temporary falsework frame, known as a centring . In the first compression arch bridges, a keystone in the middle of the bridge bore the weight of the rest of the bridge. The more weight that was put onto the bridge, the stronger its structure became. Masonry arch bridges use
1632-498: A status as a great mystic within contemporary popular spirituality , as well as considerable interest from scholars situating him within the medieval scholastic and philosophical tradition. Eckhart was probably born around 1260 in the village of Tambach , near Gotha , in the Landgraviate of Thuringia , perhaps between 1250 and 1260. It was previously asserted that he was born to a noble family of landowners, but this originated in
1728-502: A surviving collection of Eckhart's Latin works. As Eckhart was the only medieval theologian tried before the Inquisition as a heretic, the subsequent (1329) condemnation of excerpts from his works cast a shadow over his reputation for some, but followers of Eckhart in the lay group Friends of God existed in communities across the region and carried on his ideas under the leadership of such priests as John Tauler and Henry Suso . Eckhart
1824-430: A three-hinged bridge has hinged in all three locations. Most modern arch bridges are made from reinforced concrete . This type of bridge is suitable where a temporary centring may be erected to support the forms, reinforcing steel, and uncured concrete. When the concrete is sufficiently set the forms and falseworks are then removed. It is also possible to construct a reinforced concrete arch from precast concrete , where
1920-428: Is a masonry, or stone, bridge where each successively higher course (layer) cantilevers slightly more than the previous course. The steps of the masonry may be trimmed to make the arch have a rounded shape. The corbel arch does not produce thrust, or outward pressure at the bottom of the arch, and is not considered a true arch . It is more stable than a true arch because it does not have this thrust. The disadvantage
2016-575: Is assumed he studied at Cologne before 1280. He may have also studied at the University of Paris , either before or after his time in Cologne. The first solid evidence we have for his life is when on 18 April 1294, as a baccalaureus (lecturer) on the Sentences of Peter Lombard , a post to which he had presumably been appointed in 1293 (he had been ordained to the priesthood by that time), he preached

On the other hand, most scholars consider The Friend of God from

The Trinity is, for Eckhart, the revealed God and the mysterious origin of the Trinity is the Godhead, the absolute God. Matthew Fox (born 1940) is an American theologian . Formerly a priest and a member of the Dominican Order within the Roman Catholic Church , Fox was an early and influential exponent of a movement that came to be known as Creation Spirituality . The movement draws inspiration from

Therefore, whosoever will have the one must let the other go; for "no man can serve two masters". Eckhart was largely forgotten from the sixteenth to the nineteenth centuries, barring occasional interest from thinkers such as Angelus Silesius (1627–1677). For centuries, his writings were known only from

From end to end, the Krämerbrücke is 125 m (410 ft 1 in; 136 yd 2 ft) long in total. The stone bridge was constructed from limestone and sandstone in 1325, with six visible barrel arches ranging from 5.5 m (18 ft 1 in) to 8 m (26 ft 3 in) wide. The section of
2496-437: Is penetrated by the spirit of the university , in which it occurred. According to Hackett, Eckhart is to be understood as an "original hermeneutical thinker in the Latin tradition". To understand Eckhart, he has to be properly placed within the western philosophical tradition of which he was a part. Josiah Royce , an objective idealist , saw Eckhart as a representative example of 13th and 14th century Catholic mystics "on
2592-483: Is possible that the Pope's unusual decision to issue the bull, despite the death of Eckhart (and the fact that Eckhart was not being personally condemned as a heretic), was due to the pope's fear of the growing problem of mystical heresy, and pressure from his ally Henry of Virneburg to bring the case to a definite conclusion. Eckhart's status in the contemporary Catholic Church has been uncertain. The Dominican Order pressed in

The shops at street level house businesses such as artisans' workshops, specialist food outlets, antique shops, wine merchants, art galleries, cafes, etc. A bakery operates at the western end of the bridge. The upper levels of the buildings are mainly inhabited homes. Except for the buildings numbered 15, 20, 24, and 33, all
2784-432: Is that this type of arch is not suitable for large spans. In some locations it is necessary to span a wide gap at a relatively high elevation, such as when a canal or water supply must span a valley. Rather than building extremely large arches, or very tall supporting columns (difficult using stone), a series of arched structures are built one atop another, with wider structures at the base. Roman civil engineers developed

However, it is known that the commissions reduced the 150 suspect articles down to 28; the document known as the Votum Avenionense gives, in scholastic fashion, the twenty-eight articles, Eckhart's defence of each, and the rebuttal of the commissioners. On 30 April 1328, the pope wrote to Archbishop Henry of Virneburg that the case against Eckhart was moving ahead, but added that Eckhart had already died (modern scholarship suggests he may have died on 28 January 1328). The papal commission eventually confirmed (albeit in modified form)

Traditional masonry arches are generally durable, and somewhat resistant to settlement or undermining. However, relative to modern alternatives, such bridges are very heavy, requiring extensive foundations . They are also expensive to build wherever labor costs are high. The corbel arch bridge

Since then, vehicles up to a weight of 11 tons have been allowed to use the bridge, although it remains essentially a pedestrian bridge, with only small delivery and maintenance vehicles accessing it at restricted times. Since 1990 the bridge has been under continual maintenance. Over 1 million Euro has been spent on it. The bridge is still an important thoroughfare for local residents, as well as being one of Erfurt's main tourist sites. It

Suzuki and argued on the basis of Eckhart's appeals to experience that he is a mystic in the tradition of Augustine and Dionysius . Passages like the following, Johnson contends, point to experience beyond intellectual speculation and philosophizing: Those who have never been familiar with inward things do not know what God is. Like
3456-638: The Areopagite asserted a great influence on him, as reflected in his notions on the Gottheit beyond the God who can be named. Although he was an accomplished academic theologian, Eckhart's best-remembered works are his highly unusual sermons in the vernacular. Eckhart as a preaching friar attempted to guide his flock, as well as monks and nuns under his jurisdiction, with practical sermons on spiritual/psychological transformation and New Testament metaphorical content related to

The manuscript came into the possession of the Carthusians in Basel, demonstrating that some Dominicans and Carthusians had continued to read Eckhart's work. It is also clear that Nicholas of Cusa , Archbishop of Cologne in the 1430s and 1440s, engaged in extensive study of Eckhart. He assembled, and carefully annotated,
3648-520: The Dominican authorities already had concerns about Eckhart's teaching. The Dominican General Chapter held in Venice in the spring of 1325 had spoken out against "friars in Teutonia who say things in their sermons that can easily lead simple and uneducated people into error". This concern (or perhaps concerns held by the archbishop of Cologne, Henry of Virneburg ) may have been why Nicholas of Strasburg , to whom

Eckhart also continued to preach, addressing his sermons during a time of disarray among the clergy and monastic orders, rapid growth of numerous pious lay groups, and the Inquisition 's continuing concerns over heretical movements throughout Europe. It appears that some of

Roman arch bridges were usually semicircular , although a number were segmental arch bridges (such as Alconétar Bridge ), a bridge which has a curved arch that is less than a semicircle. The advantages of the segmental arch bridge were that it allowed great amounts of flood water to pass under it, which would prevent

In 1945, house numbers 11 to 14 were damaged in an allied air raid, with number 12 being completely destroyed. The buildings were reconstructed in 1954. An extensive restoration of the whole bridge structure, including the arched vaults, was carried out by

The bridge was first mentioned in 1117 after its destruction by one of many fires. The first written evidence of a "pons rerum venalium", i.e. "a market bridge", on the site dates back to 1156. Merchants and trades people had already set up market stalls on both sides of

It has been suspected that his practical communication of the mystical path is behind the influential 14th-century "anonymous" Theologia Germanica , which was disseminated after his disappearance. According to the medieval introduction of the document, its author
4416-637: The One that cannot hold back its abundance of Being. Eckhart had imagined the creation not as a "compulsory" overflowing (a metaphor based on a common hydrodynamic picture), but as the free act of will of the triune nature of Deity (refer Trinitarianism ). Another bold assertion is Eckhart's distinction between God and Godhead ( Gottheit in German, meaning Godhood or Godhead, state of being God). These notions had been present in Pseudo-Dionysius 's writings and John
4512-468: The Pope had given the temporary charge of the Dominican convents in Germany in 1325, conducted an investigation into Eckhart's orthodoxy. Nicholas presented a list of suspect passages from the Book of Consolation to Eckhart, who responded sometime between August 1325 and January 1326 with the treatise Requisitus , now lost, which convinced his immediate superiors of his orthodoxy. Despite this assurance, however,

The three elegant arches of the Renaissance Ponte Santa Trinita (1569) constitute the oldest elliptic arch bridge worldwide. Such low rising structures required massive abutments , which at the Venetian Rialto bridge and the Fleischbrücke in Nuremberg (span-to-rise ratio 6.4:1) were founded on thousands of wooden piles, partly rammed obliquely into

#17328518710174992-416: The arch and the deck is known as the spandrel . If the spandrel is solid, usually the case in a masonry or stone arch bridge, the bridge is called a closed-spandrel deck arch bridge . If the deck is supported by a number of vertical columns rising from the arch, the bridge is known as an open-spandrel deck arch bridge . The Alexander Hamilton Bridge is an example of an open-spandrel arch bridge. Finally, if

Many modern bridges, made of steel or reinforced concrete, often bear some of their load by tension within their structure. This reduces or eliminates the horizontal thrust against the abutments and allows their construction on weaker ground. Structurally and analytically they are not true arches but rather a beam with

This type of bridge has an arch whose base is at or below the deck, but whose top rises above it, so the deck passes through the arch. The central part of the deck is supported by the arch via suspension cables or tie bars, as with a tied-arch bridge . The ends of the bridge may be supported from below, as with
5280-535: The archbishop in 1326 ordered an inquisitorial trial. At this point Eckhart issued a Vindicatory Document , providing chapter and verse of what he had been taught. Throughout the difficult months of late 1326, Eckhart had the full support of the local Dominican authorities, as evident in Nicholas of Strasbourg's three official protests against the actions of the inquisitors in January 1327. On 13 February 1327, before

He stated in his protest that he had always detested everything wrong, and should anything of the kind be found in his writings, he now retracts. Eckhart himself translated the text into German, so that his audience,

Trajan's bridge over the Danube featured open- spandrel segmental arches made of wood (standing on 40 m-high (130 ft) concrete piers). This was to be the longest arch bridge for a thousand years both in terms of overall and individual span length, while the longest extant Roman bridge is the 790 m-long (2,590 ft) long Puente Romano at Mérida . The late Roman Karamagara Bridge in Cappadocia may represent

There were repeated fires on the wooden bridge in 1175, 1178, 1213, 1222, 1245, 1265, and 1293. The idea of building a stone bridge was discussed after the 1265 fire and in 1293 the municipal administration acquired all bridge rights from the monasteries, who traded goods on the bridge. However,

Generally, Roman bridges featured wedge-shaped primary arch stones ( voussoirs ) of the same in size and shape. The Romans built both single spans and lengthy multiple arch aqueducts , such as the Pont du Gard and Segovia Aqueduct . Their bridges featured from an early time onwards flood openings in

The bridge originally had stone churches at both ends, where gated entrances were erected – St. Benedict's Church at the western end and St Giles' Church ( Ägidienkirche ) at the eastern end. St Giles', the only one of

St. Benedict's Church at the west end of the bridge was sold in 1807 and later demolished, apart from its tower, in 1810, in order to build a new house. In 1895 the tower was also demolished to enable the construction of the Rathausbrücke (town hall bridge), which crosses the river parallel to

#17328518710175952-404: The creative power inherent in disinterest (dispassion or detachment). The central theme of Eckhart's German sermons is the presence of God in the individual soul, and the dignity of the soul of the just man. Although he elaborated on this theme, he rarely departed from it. In one sermon, Eckhart gives the following summary of his message: When I preach, I usually speak of detachment and say that

Pope John XXII issued a bull ( In agro dominico ), 27 March 1329, in which a series of statements from Eckhart is characterized as heretical, another as suspected of heresy. At the close, it is stated that Eckhart recanted before his death everything which he had falsely taught, by subjecting himself and his writing to the decision of the Apostolic see . It

This type is still used in canal viaducts and roadways as it has a pleasing shape, particularly when spanning water, as the reflections of the arches form a visual impression of circles or ellipses. This type of bridge comprises an arch where the deck is completely above the arch. The area between
6240-696: The desire above all to do some good. In this, he frequently used unusual language or seemed to stray from the path of orthodoxy, which made him suspect to the Church during the tense years of the Avignon Papacy. In Eckhart's vision, God is primarily fecund. Out of overabundance of love the fertile God gives birth to the Son , the Word in all of us. Clearly, this is rooted in the Neoplatonic notion of "ebullience; boiling over" of
6336-448: The divine essence and the divine persons. The very heart of Eckhart's speculative mysticism, according to Royce, is that if, through what is called in Christian terminology the procession of the Son, the divine omniscience gets a complete expression in eternal terms, still there is even at the centre of this omniscience the necessary mystery of the divine essence itself, which neither generates nor
6432-550: The earliest surviving bridge featuring a pointed arch. In medieval Europe, bridge builders improved on the Roman structures by using narrower piers , thinner arch barrels and higher span-to-rise ratios on bridges. Gothic pointed arches were also introduced, reducing lateral thrust, and spans increased as with the eccentric Puente del Diablo (1282). The 14th century in particular saw bridge building reaching new heights. Span lengths of 40 m (130 ft), previously unheard of in

In China, the oldest existing arch bridge is the Zhaozhou Bridge of 605 AD, which combined a very low span-to-rise ratio of 5.2:1, with the use of spandrel arches (buttressed with iron brackets). The Zhaozhou Bridge, with a length of 167 feet (51 m) and span of 123 feet (37 m), is the world's first wholly stone open-spandrel segmental arch bridge, allowing

Pope John Paul II voiced favorable opinion on this initiative, even going as far as quoting from Eckhart's writings, but the outcome was confined to the corridors of the Vatican . In the spring of 2010, it was revealed that there had been a response from the Vatican in a letter dated 1992. Timothy Radcliffe , then Master of
6816-521: The later nineteenth century for the recovery of Eckhart's works was Henry Denifle , who was the first to recover Eckhart's Latin works, from 1886 onwards. During the late nineteenth and early twentieth century, much Catholic interest in Eckhart was concerned with the consistency of his thought in relation to Neoscholastic thought – in other words, to see whether Eckhart's thought could be seen to be essentially in conformity with orthodoxy as represented by his fellow Dominican Thomas Aquinas . Since
6912-481: The mid-nineteenth century scholars have questioned which of the many pieces attributed to Eckhart should be considered genuine, and whether greater weight should be given to works written in the vernacular, or Latin.

The festival is officially opened by an actor playing the folkloric character Till Eulenspiegel , who according to legend visited Erfurt and fooled
7104-441: The other buildings on the bridge are municipal property. In medieval times buildings were not numbered and many people were illiterate, so house signs were sometimes hung on buildings or placed over doorways, so that the house and its occupants could be easily located. Examples of these can still be seen on the bridge, as well as original doors which may be hundreds of years old. The Stiftung Krämerbrücke (Krämerbrücke Foundation)
7200-821: The piers, e.g. in the Pons Fabricius in Rome (62 BC), one of the world's oldest major bridges still standing. Roman engineers were the first and until the Industrial Revolution the only ones to construct bridges with concrete , which they called Opus caementicium . The outside was usually covered with brick or ashlar , as in the Alcántara Bridge . The Romans also introduced segmental arch bridges into bridge construction. The 330 m-long (1,080 ft) Limyra Bridge in southwestern Turkey features 26 segmental arches with an average span-to-rise ratio of 5.3:1, giving
7296-592: The professors at the university that he had taught a donkey to read. Arch bridge Possibly the oldest existing arch bridge is the Mycenaean Arkadiko Bridge in Greece from about 1300 BC.
