Stability and conservation of the Maxentius Basilica in the Roman Forum

Abstract

Originally extended over 6500 square metres, the Basilica of Maxentius was one of the biggest and most outstanding buildings of Roman architecture. Only one third of the monument is still standing. In celebration of the Christian Holy Year of 2000 (the Jubilee), the Soprintendenza Archeologica di Roma (SAR) started an extended project with the purpose of restoring the terrace and of studying the structural problems of the monument. CISTeC was appointed to the structural part of the project, including the study of the foundations and the proposal for the consolidation project.

The present paper reports the conclusions of the static and dynamic studies that were carried out both on the present-day Basilica and on the model of the original basilica. The results concluded that the monument could be subjected to seismic risks. Following such conclusions, a provisional consolidation project (which is currently in progress) and three final consolidation proposals were submitted to SAR. The immediate application of the provisional consolidation will give time to SAR to decide which of the final projects is the most Suitable, while still protecting and preserving the monument. The structural studies and the projects are briefly described in this paper.     

Coalport Bridge: A Study in Historical Interpretation

Abstract

Industrial archaeologists frequently demand the preservation of monuments. Such preservation can be justified on the grounds that a monument has an educational function, or sometimes that it has potential for excavation. It is the purpose of this article to suggest that a surviving monument continually poses questions about its own past, and about wider historical issues, and to show how the understanding of one particular monument, the Coalport Bridge, has increased over the last twelve years, not just because new documentary sources have come to light, but because it has been possible to use the evidence of the structure itself to test the authenticity of other sources.     

Historical Survey and Chronology of Bonajuto Chapel in Catania,Italy

Located in the historical center of Catania, Italy, in the Civita district, the Bonajuto Chapel is one of the oldest and best-conserved buildings of the city, which has survived the numerous earthquakes that struck eastern Sicily during the medieval and the modern ages, such as those particularly devastating in 1169 and 1693. However, both the date of this small monument, as well as its original use, still remain uncertain, as literary and documentary evidence are scarce and fragmentary. Most historians, analyzing prevalently the stylistic and constructive aspects, interpreted the chapel as a place of worship and assigned its construction to a rather long period of the early Middle Ages, from the 5th or 6th centuries ad to the 8th or 9th centuries ad—the phase during which the island was under the Byzantine domination. The excavations carried out in 1930 to 1939 and the last restoration works (in 2003) have not provided explicit chronological data. Its age determination is considered essential for a better knowledge of the real influence of this domination on the architecture of the Island. Therefore, a multidisciplinary and accurate analysis of the building using the existing bibliography has been carried out also in order to understand the functional and morphological transformations of the chapel during its long life. The thermoluminescence absolute dating methodology applied to some brickwork elements of the construction, has placed the monument chronology in a period of time that is notably shorter than that previously noted here. These new data, with the study of the architectural structure, have made a significant step forward in the knowledge of the chapel history.     

The Dynamics of Heritage-Making at an Archaeological Site in South 24 Parganas,Bengal, India

Archaeological heritage is seldom fixed in time. Heritage-making is an ongoing process deeply entwined with social/cultural memory and identity formation. These processes are traced through an archaeological monument, located in the Sundarbans, in the South 24 Parganas district of West Bengal, India. The monument, named ‘Jatar Deul’, is a brick tower, stylistically labelled as a rekha deul — a curvilinear tower with a cruciform ground plan —belonging to the Orissan architectural style. Its exact chronology is unknown, as is its creator, although it is stylistically dated to the thirteenth century ce. It has survived more in myths, legends, and local tradition than in historical sources. This paper explores how the monument becomes a site of memories and how multi-vocal identities are forged around the locus of the site, now revered as a sacred place of Shaiva worship. The Postcolonial State has only a marginalized presence and the main stakeholders remain non-professional archaeologists, local schoolteachers, and the local population living in close vicinity. Identity work at the site is no longer the archetypal Bengali/regional identity seen in the pre-independence context, but reflects sub-regional cultural/religious affiliations. This paper is the result of ethnographic research, particularly interviews, of select sections of the local community, focusing on the recent organization of an annual fair at the site, which has thrown up questions on archaeological tourism. On the whole, this study examines how an archaeological monument is shaped and formed in the present in contemporary South Asia.     

Identifying a technological style in the making of lime plasters at Teopancazco (Teotihuacan,México)

The aim of this article is to focus on the technology of archeological plasters at Teotihuacan (Central Mexico), from the Classic Period (200–650 A.D.), focusing in the study of Teopancazco, a neighborhood center in the city. Petrographic and chemical analyses by OM, SEM-EDS, and LA-ICP-MS were conducted to characterize samples from different constructive phases and sectors of the neighborhood center, to determine the provenance of the raw materials employed in the manufacturing (e.g., volcanic glass shards) and to assess whether a shift occurred in the manufacturing of plasters and in the procurement strategies of raw materials during the different phases. The results of the analyses show that almost no changes occurred in the making of the plaster during more than four centuries and allow us to consider the presence of a technological style in their manufacture, which is characterized by the making of plaster by mixing lime with volcanic glass shards, which in the case of Teopancazco were derived from the Altotonga (Veracruz) magmatic system. The data at our disposal suggest that this style was developed in Teopancazco and later introduced throughout the city of Teotihuacan in the Early Xolalpan phase (A.D. 350), although we still do not know whether the provenance of the raw materials is the same. The wide distribution of this technological tradition could be due to the technological properties of the materials and/or the influence of the intermediate elite who ruled over Teopancazco. The paper confirms that the study of material culture and technology sheds light on broader cultural aspects of ancient societies.     

Shifting monument production chains and the implications for gravestone design on Prince Edward Island, 1820–2005

This paper examines changing gravestone design in Prince Edward Island (PEI) (1820–2005) and relates these changes to changing modes of production in the monument industry. Information from field surveys, newspaper advertisements and business correspondence reveals how supply-side factors helped shape the morphogenesis of the island's cemetery landscapes. Among these, different sources of raw materials and manufacturing innovations over time resulted in the use of harder, more durable types of stone. With these changes, gravestone production and design moved increasingly away from local monument works towards off-island producers in Vermont, New Brunswick and Nova Scotia. Since the early 20^th century, PEI's gravestone suppliers vertically integrated along Fordist mass-production lines and increased choices available to local monument sellers and their consumers.     

Plasters from Different Buildings of the Sacred Precinct of Tenochtitlan (Mexico City): Characterization And Provenance

In this work, we present the results of the characterization of 20 lime plaster samples taken from the Sacred Precinct of Tenochtitlan (Mexico City), the ancient capital of the Aztec empire. The samples come from different buildings of this precinct (A, B and D) and from the west façade of phase VI of the Templo Mayor pyramid. The objective of the work is to characterize the plaster samples, to understand the raw materials used, and to evaluate the presence of similarities and differences among the samples in the building techniques and raw materials employed. All the samples were studied with OM, SEM–EDS and LA–ICP–MS. The study provided evidence of the plastering and replastering practice in the same constructive phases. The results of the analyses showed the existence of important similarities and differences among buildings and constructive phases in the Sacred Precinct. In order to understand the provenance of the limestone used in the plasters, the lumps and the binder of the samples were analysed. The results were compared with those of the limestone outcrops located in central Mexico. The provenance study showed that all the limestone used in the construction of the analysed buildings of Tenochtitlan's Sacred Precinct comes from the Tula region.     

Saving the Sweet Track: The in situ preservation of a Neolithic wooden trackway,Somerset, UK

Abstract

The Sweet Track is the oldest known wooden trackway in Europe. Part of the trackway is preserved in situ in a nature reserve under an active system of hydrological management, designed to prevent damage to the monument from desiccation. The English Heritage-funded project, reported here, was established to assess the condition of the monument and the effectiveness of the management regime. The results have shown that although the trackway is highly deteriorated it still holds a wealth of archaeological information. The decay of the wood probably occurred gradually over several thousand years but the present management regime should be able to ensure its continued survival.     

Microclimate analysis of deteriorated wall paintings: With restitution of original decoration through imaging

Abstract

The restoration of deteriorated wall paintings in an underground environment requires at the outset a complex analytical approach designed to clarify the deterioration processes. These can be identified and prioritized using continuous microclimatic monitoring with multichannel analytical loggers, providing abundant data on climatology, airflow and hydrogeology in real or semireal time. The investigator can therefore have an almost instantaneous idea of the evolving microclimatic conditions of the monument, identifying among other variables the condensation or evaporation phases of the walls and the rising or sinking of the underground water table when the monument ‘has its feet in the water’, as in the case described here of St Emilion (France). In addition, electronic image capture in situ can be used to decode and restitute very damaged paintings that have become difficult to read, with a view to their being eventually presented to the public.

中国明代木质古建西安鼓楼彩绘的分析研究

鉴于有关中国木质古建彩绘材料及技术的研究报道较少,本工作通过光学显微镜、扫描电镜能谱(SEMEDX)、X射线衍射及气相色谱质谱(GC/MS)分析方法,对建于公元1380年的中国西安明代鼓楼木建表面彩绘样品进行了科学检测研究,分析了其中的无机材料组成及彩绘所用粘合剂,并收集了所涉及到的相关历史资料。分析结果表明,木建表面彩绘的材料组成和制作技术与历史调查获得的信息完全吻合。地仗层主要由粘土、石灰、干性油(桐油)及纤维织物组成,且地仗层保持最初的原材料。颜料分析结果显示,尽管修复时所使用的粘合剂与最初建造时的粘合剂完全相同,但目前彩绘的颜料即有原来使用的材料,也有十八世纪修复时所使用的材料。     

Remarks on Some of the Churches of Anglesey

Reconsideration of three published reports about the ruined church at Stone-by-Faversham is shown to lead to some new interpretations of its structure and history 1 especially when account is taken of evidence hitherto left latent in the building and of evidence as yet unpublished from an investigation in 1926. Moreover a new weapon for interpretation of the sequence of the several phases of the building has been developed by study of the extent to which material .from the earliest phase has been used in the fabric of later phases; and reasons are given for re-interpreting as nave-altars the masses of masonry which have in the past been regarded as part of a very confosing east wall of the first stone nave. Plans and .floor-levels are shown for the four principal phases of development 1 and we make a suggestion for a small change in the way the monument is displayed 1 in order to make its history more easily understood and also to protect its most ancient parts .from unnecessary risks. The substance of this paper was delivered to the Institute at its meeting on 11 February 1981.     

Awake anon the tales of valour: the career of a war memorial in St. Catharines,Ontario

Memorials cultivate a common understanding of the past that is communicated through the celebration of select people, places or events. Because memorials are located in public space and crafted from time‐defeating materials, the process of commemoration is inherently political. Scholars have studied this process to discover the agendas that inform the ideological content of memorials, but rarely how this content is received by its audience. This question is especially pertinent when memorials outlast the generation and the ideology that created them. This study attempts an answer by exploring the career of one memorial: the monument in St. Catharines, Ontario, dedicated to Private Alexander Watson, a casualty of the Battle of Batoche (1885). It finds that the monument's significance was transformed by political, cultural and historiographical shifts. While its local audience has forgotten its specific message, its generic intent to honour fallen soldiers is still recognized.

The Monument to Victory in Bolzano: desacralisation of a fascist relic

The Monument to Victory in Bolzano, raised to remember Italian soldiers who fell in the First World War and to celebrate the victory over the Austro-Hungarian army, was contested from the moment of its installation in 1928. The German-speaking inhabitants of Bolzano were offended by its expression of Italian patriotism and the monument continued to symbolise the antagonism between the Italian- and the German-speaking population in the period following the end of Second World War. The monument’s explicit fascist propaganda attracted strong polemical reactions and some political groups even asked for it to be demolished. A recently-opened permanent exhibition in the crypt of the monument explores the twentieth-century dictatorships of Italy and their impact on Bolzano. Its historicisation offers a new interpretation of the monument – not one based on a schism between the populations of Bolzano, but rather one proposing reconciliation. This historicisation happens through the contextualisation of the monument, an efficient tool for the ‘desacrilisation’ of politically charged buildings; by exposing the detested ideology that they represent, they are stripped of their original ‘sacred’ character. This process also shows that it is possible for controversial, politically significant structures to become legitimate parts of a country’s modern heritage.     

Remarks on British and Roman Urns

The parish church of St Andrew at Irnham in Lincolnshire possesses a richly carved stone monument dating to around 1340 which bears the arms of Sir Geoffrey and Agnes Luttrell, associated with the celebrated Luttrell Psalter. The form, imagery and function of this monument are problematical and are discussed first in order to create a context for an unusual aspect of its architecture, namely that its inner vault is a miniature copy, unique in this part of England, of the main vault of the choir of Wells Cathedral, a so-called ‘net’ vault. Amongst the reasons for such an unusual citation may be the existence in Somerset, in the diocese of Wells, of one branch of the Luttrell family at the time this monument was raised.     

Heritage and national identity: Exploring the relationship in Romania

Abstract

Within heritage studies the relationship between national heritage and national identity is frequently taken as axiomatic. The construction of a national heritage is an important part of nation‐building, and historic buildings and monuments can be powerful symbols of a nation's aspirations and identity. Yet this relationship has received relatively little empirical investigation. This paper reports an exploratory study of the heritage/national identity relationship in Romania which focuses on just one Roman monument – Trajan's bridge. For many Romanians the monument is a powerful symbol of their identity representing Dacian and Roman origins, Latinity, and the continuity of Romanian settlement in Transylvania. The monument was also seen by some as an important symbol of Romania's attempt to construct a post‐Communist identity, and to forge closer links with western Europe. However, the meanings of the monument are not shared by all Romanians, and in particular are strongly contested by Romania's Hungarian minority.     

THE GRANITE COLUMN IN MODON: HOW TO MAKE A STONE SAY WHAT YOU WANT IT TO SAY!

Summary.   The 3 km long ramparts of the castle of Modon survive remarkably unscathed despite the attacks of Man and Nature over the centuries. The most interesting monument which remains, a column of red granite, crowned with a capital and a stone slab, has escaped the looters of antiquities who often passed by Modon. It has also escaped the scholars who have failed to give a reliable interpretation of the monument. This paper seeks to deal with this question and to set the monument in its proper historical context.
