Natural Risks and Conservation of Rammed-earth Defensive Architecture: Approach to the Damages Caused by Earthquakes in the Alcazaba of Almeria and the Wall of La HoyaThe aim of this work is to present the results obtained in the framework of the PREFORTI Project. The particular case analysed is the damages caused by earthquakes in the medieval fortifications of Almeria and the consequences on their conservation. Almeria is a zone of important seismic activity. This particularity has caused many problems to conserve its Islamic military architecture. Within this work, we include the most important earthquakes that have affected this heritage since the late fifteenth century and the constructions damaged –to a greater or lesser extent– by them, including their specific damages and an approach to their state of conservation. Due to its importance within the military constructions, we present the case study of the Alcazaba of Almeria and the wall of La Hoya, focusing on the second one. These paradigmatic constructions were widely affected by the earthquakes since the late fifteenth century. Beyond the analysis of the damages caused by the earthquakes and the different historical restorations to mitigate them, we include the emergency measures proposed in the framework of the PREFORTI Project for its better conservation against the different risks, as well as the microzonation mapping of the natural seismicity risk for the section of the wall of La Hoya in order to delve in the study of the vulnerability of this cultural asset against this natural risk, as a mechanism for its better preventive conservation.

ABSTRACTThis article offers a case-study of an early preservation campaign to save the remains of the fifteenth-century Crosby Hall in Bishopsgate, London, threatened with demolition in 1830, in a period before the emergence of national bodies dedicated to the preservation of historic monuments. It is an unusual and early example of a successful campaign to save a secular building. The reasons why the Hall's fate attracted the interest of antiquaries, architects, and campaigners are analysed in the context of the emergence of historical awareness of the domestic architecture of the late fifteenth and sixteenth centuries, as well as wider recognition of the importance of this period for Britain's urban and commercial development. The Hall's associations with Richard III and other historic figures, including Thomas More and Thomas Gresham, are shown to have been particularly important in generating wider public interest, thereby allowing the campaigners to articulate the importance of the Hall in national terms. The history of Crosby Hall illuminates how a discourse of national heritage emerged from the inherited tradition of eighteenth-century antiquarianism and highlights the importance of the social, professional, and familial networks that sustained proactive attempts to preserve the nation's monuments and antiquities.

This paper examines the possible causes of damage to historic rammed earth structures based on a case study of a medieval and later building, formerly a preceptory of the Military Orders, in the village of Ambel in Aragon, north-east Spain. Structural and water-based mechanisms of damage are reviewed and an engineering basis for the cause of damage is proposed. Since a number of repair strategies have already been attempted on this structure, their effectiveness is also discussed. A four storey granary at the north-east corner of the preceptory complex is described in detail since it encapsulates many damage mechanisms and repair strategies which are common to historic rammed earth. The granary tower has a random rubble foundation, which is probably in part the remains of previous building, with rammed earth walls for the three storeys above. This rammed earth was originally rendered and scored to imitate fired brick but almost all of this has now fallen away. The gable end of the building has fired brick quoins, and now leans outwards slightly at the head of the wall. There is evidence of water damage because the building was neglected in the past, though not enough to initiate collapse. Structural and water based damage mechanisms are identified, and example repair strategies used at Ambel are described.

The avariz and nüzul levies were among the most important of the regular sources of government revenue in the Ottoman empire during the seventeenth century, but there has been relatively little study of them. Originating in the late fifteenth century as irregular imposts levied at times of military need, it is clear that by the first quarter of the seventeenth century avariz and nüzul had become virtually annual levies throughout the majority of the Rumelian and Anatolian provinces. This article examines the nature of these levies as seen through collection procedures in the province of Karaman in the period 1620 to 1700, showing how the Ottoman financial administration developed this relatively new and lucrative source of income in a consistent and fair manner.

The ‘seventeen Netherlands’ owed their existence entirely to the energies of their rulers. Until 1548 when this hotchpot of duchies, counties and lordships was united in the Burgundian circle of the Empire, the boundaries of the Low Countries had expanded or contracted according to the military and diplomatic fortunes of their princes: there was nothing natural or inevitable about them. Charles V had, for example, threatened to annexe the prince-bishopric of Münster in 1534–5, as he had added Utrecht only a few years earlier. Nor can the incorporation of the duchy of Gelre in 1543 be considered the outcome of an ineluctable historical process. Since the late fifteenth century the rulers in the Low Countries had sought to assert their control over the duchy. But there had been times when it seemed as though Gelre, which looked Januslike both up and down the Rhine, might, in combination with Jülich and Cleves, have constructed a formidable anti-Habsburg constellation into whose orbit a large part of the northern Netherlands would be drawn.

Notwithstanding the reputation of Josquin’s Ave Maria…virgo serena as a touchstone of late–fifteenth-century musical style, little is known about the context in which the piece emerged. Just over a decade ago, Joshua Rifkin placed the motet in Milan ca. 1484; more recently, Theodor Dumitrescu has uncovered stylistic affinities with Johannes Regis’s Ave Maria that reopen the debate about the provenance of Josquin's setting. Stipulating that the issues of provenance and dating are for the moment unsolvable, I argue that the most promising way forward is to contextualize this work to the fullest extent possible. Using the twin lenses of genre and musical style, I investigate the motet’s apparently innovative procedures (e.g., paired duos, periodic entries, and block chords) in order to refine our understanding of how Josquin’s setting relates to that of Regis and to the Milanese motet cycles (motetti missales). I also uncover connections between Josquin’s motet and the music of earlier generations, above all the cantilena and the forme fixe chanson, that offer new insights into the development of musical style in the fifteenth century. The essay concludes by positioning the types of analyses explored here within a growing body of research that enables a revitalized approach to longstanding questions about compositional development and musical style.

Floods are natural risk with a very high frequency, which causes to environmental, social, economic and human losses. The floods in the town happen mainly due to human made activities about the blockage of natural drainage, haphazard construction of roads, building, and high rainfall intensity. Detailed maps showing flood vulnerability areas are helpful in management of flood hazards. Therefore, present research focused on identifying flood vulnerability zones in the Pune City using multi-criteria decision-making approach in Geographical Information System (GIS) and inputs from remotely sensed imageries. Other input data considered for preparing base maps are census details, City maps, and fieldworks. The Pune City classified in to four flood vulnerability classes essential for flood risk management. About 5 per cent area shows high vulnerability for floods in localities namely Wakdewadi, some part of the Shivajinagar, Sangamwadi, Aundh, and Baner with high risk.

Chapter 3 approaches the notion of trophy through historical accounts of the Christianization of the Córdoba and Seville Islamic temples in the thirteenth-century and the late-fifteenth-century conquest of Granada. The first two examples on Córdoba and Seville are relevant to explore the way in which medieval chronicles (mainly Rodrigo Jiménez de Rada and his entourage) turned the narrative of the Christianization of mosques into one of the central topics of the restoration myth. The sixteenth-century narratives about the taking of the Alhambra in Granada explain the continuity of this triumphal reading within the humanist model of chorography and urban eulogy (Lucius Marineus Siculus, Luis de Mármol Carvajal, and Francisco Bermúdez de Pedraza).
