AN ANALYTICAL RESPONSE OF CHURCH BELLS TO EARTHQUAKE EXCITATION

Occasionally there is an earthquake in the UK during which church bells are reported to have been set ringing. The motion of a medium sized church bell has been simulated and the response to earthquake records from the Parkfield earthquake of 1966 has been calculated. The response of the bells is found to depend on the mechanical properties of the bell and the tower in which it is hung. The analyses do show that for a bell to ring in an earthquake the peak ground acceleration is in the range 0.97 to 29.4 m s^?2 considerably in excess of the range indicated by the MMI VI “church and school bells ring” of 0.4 to 1.5 m s^?2. The best correlation between recognised earthquake parameters and the ringing of the bell was obtained by combining the spectral values for clapper-bell angle, obtained from the linearised set of equations, at the bells natural frequencies using the SRSS method. The values of this parameter to set the bell ringing was in the range 0.25 and 0.38 rad, compared with the actual striking angle 0.54 rad.     

‘I call the people.’ Church bells in fourteenth-century Catalunya

Bells were an inescapable part of fourteenth-century urban life. They signalled the hours of the day and times for prayers; they warned of tempests and enemy armies; they heralded masses, funerals, and deaths. The pealing of bells brought men, women, and children together, choreographing communal behaviour in time and space. Bells echoed the vox Domini, calling out the deaths of holy men and women, celebrating the working of miracles. The ubiquitous presence of bells reflected the omnipresence of God in the medieval world. Their echoes transformed private moments into collective experiences, elevating the mundane into the miraculous. Scholars have rarely examined the religious aspects of bells, looking instead at their more practical side, especially their utilisation as markers of time and the allegedly concurrent rise of mercantile culture. This article approaches bells from the viewpoints of those men and women who heard them and wanted them rung. Focusing on sources from Christian clerics, we see that medieval men rang the bells with clear, but many possible, purposes in mind. By marking time and prayers, Christian church bells helped to create and facilitate communities within dioceses, spurring and choreographing their actions. During funerals, bells broadcast private moments, giving them communal significance. The transformative, creative function of bells is clearest in their role in miracles. In Manresa, the vision experienced by a few became a community affair when the church bells gathered the people; the bells transformed an ordinary day into one where the people, as a community, received divine favour. Finally, with the deaths of holy persons, the tolling of bells transformed private, even anonymous deaths, into moments of wonder as God’s hand touched the world.The pealing of bells defined Christian communities in the Mediterranean and, at the same time as rulers and elites throughout the region were seeking to control minority groups, those same groups were seeking to exercise control over the sounds within their own communities. Through the pealing of bells, churchmen across Catalunya sought to direct the thoughts and prayers of their listeners. When the Christian clerics of Catalunya rang their churches’ bells, they had specific aims in mind, yet, as the evidence demonstrates, the pealing of the bells never meant just one thing. This article demonstrates that there is much more to understanding medieval bells than knowing ‘for whom the bell tolls’; we have to look at the listeners as much as the ringers in order to understand their cultural significance in medieval Europe. This article is a first step in how such a study could be begun.

For Whom the Bells Fall: Metals from the Cenote Sagrado,Chichén Itzá

Bells of copper and copper alloys and gold–copper alloys were deposited in events at the Cenote Sagrado at Chichén Itzá, Mexico during the site's primary occupation (ad 750–1050) and in later centuries. Housed in three museums in the United States and Mexico, bells (n = 38) were evaluated for traces of fabrication and alteration using Vis–UV–IR optical microscopy. Bulk compositions were determined through p‐ED‐XRF. Phases and compositional variation by depth were characterized through XRD and RBS. The technological styles of bell groups were ascribed to communities of metallurgical practice, from West and Central Mexico to Costa Rica and Panama.     

Of saints,sows or smiths? Copper-brazed iron handbells in Early Medieval England

ABSTRACT

Copper-brazed iron handbells were a distinctive feature of monastic life in Early Medieval Ireland, Scotland and Wales. Handbells were used in liturgy, prayer, worship, and later as reliquaries. In England, brazed bells of the seventh to ninth centuries take on a greater range of sizes and forms and are found on a wider variety of sites. As a consequence, their roles within Christianity have been questioned, and associations with animals and itinerant smiths have been emphasised instead. Recent archaeological investigation of an Anglo-Saxon marsh-island at Little Carlton, Lincolnshire has resulted in one of the largest assemblages of copper-brazed iron bells from any site in England, comparable to similar collections from Flixborough and Brandon. Taking into consideration the inclusion of brazen bells in some ritualistic ‘closure hoards’, this paper argues that whilst Anglo-Saxon plain iron bells may have fulfilled a range of profane functions, those that were copper-brazed, regardless of their size, were important objects amongst early Christian communities in England, and the Northumbrian church in particular.

The rise and fall of a speculative bubble: geostrategic concerns,public debate and the promotion of an American trans-oceanic canal in the 1820s

The article examines the interest in the United States for the construction of a trans-oceanic canal in Central America. In 1820, William Davis Robinson published a book, Memoirs of the Mexican Revolution, which contained an appendix discussing the practicability of building a trans-oceanic canal including detailed analysis of the potential routes for its construction. The appendix sparked a lively debate among American political and economic leaders. This debate would not abate until the enormity of the financial and engineering realities of the project coupled with the continuing political instability of Mexico, Greater Colombia, and the Republic of Central America dampened investor enthusiasm.

The Block of Tin Dredged up in Falmouth Harbour,and now in the Truro Museum

A campaign of excavations in advance of development in Greater London during the 1970s and 1980s has led to a major programme of post-excavation analysis and publication of the results. The background to this programme reflects the way in which archaeology in Britain has developed since the 1970s. A highly structured approach has been adopted to the programme, involving a series of stages and careful selection of material for detailed analysis and publication. Some twenty-five monographs and nineteen major articles will result from the work, covering prehistoric, Roman, Saxon, medieval, and post-medieval topics across Greater London. Prehistoric landscapes in West London, Roman Southwark, the Middle Saxon emporium of Lundenwic, medieval religious houses, and post-medieval industries in Southwark will be particular foci of attention. In addition, an archive guide giving summary details of all the excavations undertaken will be produced. The programme will make a substantial contribution to our knowledge of the archaeology of Greater London.

Cultural Effects on Phenetic Distances Among Postclassic Mexican and Southwest United States Populations

The Southwest United States (US) and Mesoamerica are often thought of as disparate regional networks separated by Northern Mexico. Chaco Canyon in the Southwest US, Tlatelolco in Central Mexico and Casas Grandes in Northern Mexico, all had large inter‐regional trade centres that economically connected these networks. This study investigated how factors such as geographic distance, shared migration history, trade and political interaction affected biological relationships and population affinities among sites in Mexico and in Southwest US during the Postclassic period (ad 900 ~ 1520). Distances based on cultural and geographic variables derived from archaeological and ethnohistoric data were compared with phenetic distances obtained from dental morphological traits. The results of Mantel tests show trade (corr = 0.441, p = 0.005), shared migration history (corr = 0.496, p = 0.004) and geographic distance (corr = 0.304, p = 0.02) are significantly correlated with phenetic distances, whereas political interaction (corr = 0.157, p = 0.133) is not. Partial Mantel tests show trade (corr = 0.223, p = 0.049) and shared migration history (corr = 0.493, p = 0.003) remain significant when controlling for similarities with geographic distance, although the correlation for trade and phenetic distance is lowered. Geographic distance is not significant when similarities with trade (corr = 0.067, p = 0.681) and shared migration history (corr = 0.148, p = 0.127) are controlled. These results highlight the importance of economic relationships and shared migration history across geographic regions in interpreting biological relationships among contemporaneous populations in prehistoric Mexico and the Southwest US.

Ancestral Puebloan mtDNA in context of the greater southwest

Ancient DNA (aDNA) was extracted from the human remains of seventy-three individuals from the Tommy and Mine Canyon sites (dated to PI-II and PIII, respectively), located on the B-Square Ranch in the Middle San Juan region of New Mexico. The mitochondrial DNA (mtDNA) haplogroups of 48 (65.7%) of these samples were identified, and their frequency distributions were compared with those of other prehistoric and modern populations from the Greater Southwest and Mexico. The haplogroup frequency distributions for the two sites were statistically significantly different from each other, with the Mine Canyon site exhibiting an unusually high frequency of haplogroup A for a Southwestern population, indicating the possible influence of migration or other evolutionary forces. However, both sites exhibited a relatively high frequency of haplogroup B, typical of Southwestern populations, suggesting continuity in the Southwest, as has been hypothesized by others (8, 9, 29, 45 and 57). The first hypervariable region of twenty-three individuals (31.5%) was also sequenced to confirm haplogroup assignments and compared with other sequences from the region. This comparison further strengthens the argument for population continuity in the Southwest without a detectable influence from Mesoamerica.     

Archaeological Excavations of the Medieval Royal Kincardine Landscape,Aberdeenshire, Scotland

KINCARDINE PARK is among the earliest and largest medieval parks in Scotland. It was royally owned and is believed to have served as a hunting park throughout the 13th and 14th centuries. Nearby are the ruins of Kincardine Castle, considered to be associated with the park, and one of the first Scottish stone-built castles. This paper presents the results of excavations conducted in the park landscape, and at the stone-built Scottish castle. New insights are provided on how medieval Scottish parks were constructed and used, and the cultural significance of these monuments is explored.     

The archaic prehistory of the North American Southwest

Evidence today suggests that by at least 8000 to 8500 B.P., Archaic hunter-gatherer economies were established throughout the North American Southwest. The Early Archaic seems to be a period of considerable variability across the subregions; this may be a product of currently slim knowledge of the period, or it may indicate that the region witnessed considerable flux. With the Middle Archaic period from 5500 to 3500 B.P. there seems to be greater similarity in material culture across the region and a definite increase in the number of known sites. Finally, the Late Archaic/Early Agricultural period from 3500 to 2000 or 1500 B.P. sees the establishment of a mixed farming-foraging economy in much of the Southwest with apparently major changes in subsistence-settlement systems. Preagricultural Archaic land use patterns are known in broad outline but not in detail; high mobility by small social groups in an annual round would have permitted exploitation of diverse biotic communities. In most parts of the region, significant socioeconomic change accompanies the incorporation of agriculture into the late preceramic period, as witnessed by the appearance of longer-term residential sites with pitstructures and storage features.     

Feminism from the Margin: Challenging the Paris/Banlieues Divide

This paper aims to cast light on specifically French constructions of gender, citizenship and nationhood and articulate two bodies of work, one dealing with political mobilizations of racialized minorities in the French context, and the other dealing with gender concerns in urban policy. Emerging social movements in the urban area of Paris are having to take position in a context in which a normative “state feminism” is being used to stigmatize working‐class neighbourhoods in the banlieues as well as their male inhabitants. This paper considers the “double bind” in which feminist activists, and women more generally, find themselves as a result. It argues that some formerly silenced groups are being granted space for expression by the current foregrounding of “women” in urban policy. Drawing on bell hooks' insights on the margin/centre tension in feminist theory as a useful way of thinking about the spatial dimension of these issues, the paper looks at one group in particular that defines itself and its strategies in spatial terms.     

Iron age farms in Southwest Norway the development of the agrarian landscape on Jæren

In this issue of NAR the development of the agrarian landscape and the farm structure in the Iron Age in Southwest Norway ‐ especially in the district of Jæren ‐ is taken up as a subject for discussion. Two publications by Bj?rn Myhre (Funn, fornminner og ?degårder. Jernalderens bosetning i H?yland Fjellbygd. Stavanger Museums Skrifter 7,1972 and The Iron Age Farm in Southwest Norway. NAR 6, No. 1, 1973) are commented upon by Björn Ambrosiani, Arnvid Lillehammer, Sven‐Olof Lindquist, Perry Rolfsen and Ulf Sporrong. Bj?rn Myhre's reply to the comments closes the discussion.     

The Virgin Anasazi,far western Puebloans

In the American Southwest, the Virgin Anasazi region included the western part of the Colorado Plateaus and the river valleys of the adjoining Mojave Desert in Utah, Nevada, and Arizona. This occupation spanned the Puebloan periods from Basketmaker II to Early Pueblo III, roughly A.D. 1 to A.D. 1200. Virgin Anasazi subsistence combined cultivation with hunting and gathering. Current research is unveiling a prehistoric society with flexible food procurement strategies and group organization. They underwent a version of the pit house-to-pueblo transition familiar from the Kayenta and northern San Juan areas. Both intra- and interregional exchange seems to have peaked in Late Pueblo II times and then fallen off prior to the end of their culture history. Face-to-face communities remained small, even into the late 1100s, when other Anasazi areas saw the beginnings of aggregation. Their fate, early in the widespread abandonment of the northern Southwest, remains to be understood.     

Theatre,mathematics, and the aesthetics of infinity: Complicite’s A Disappearing Number

ABSTRACT

Complicite's A Disappearing Number is one of the best examples of contemporary plays that use theatrical strategies to convey complex scientific ideas. Complicite uses performance to stage the complex mathematical concepts of partition and infinite convergent series, taking inspiration from the statement by renowned British mathematician G. H. Hardy that “a mathematician... is a maker of patterns”. As well as performativity, other elements in the play contribute to performing mathematics on the stage, elements such as time and space, narrative structure, thematic content, and characterization. Complicite introduces a complex pattern that runs throughout the play to connect these elements to form a complete whole. These elements effectively work with each other to release a set of clues that guide the audience towards decoding the play's pattern. This study provides an in-depth analysis of these connections and the complex process of decoding the pattern in the play.     

Myth,Primogeniture and Long Distance Trade‐Friends in Northwest New Britain,Papua New Guinea

ABSTRACT The origins of ceremonies for firstborn children and long distance trade networks are embedded in Bariai mythology and cosmology. Based on my ethnographic research and the ethnographic reportage contained in the Australian colonial Patrol Officers' Reports, this paper explores the pre‐ and post‐contact trade networks of Bariai parents as they pursue a reputation for ‘renown’ by entering into complex trade‐friendships (sobo) and exchanges for the necessary wealth to undertake one (of seventeen) firstborn ceremony, the mata pau or ‘new eye.’ My intent in this paper is to (1) reiterate that a people and their culture can only be understood within regional systems of relationships; (2) indicate the manner in which long distance trade‐friendships were created and maintained over a long period of time; (3) show how these socio‐economic institutions are embedded in Bariai cosmology and thus made meaningful; (4) attest to the vitality and importance of these systems despite the impact of modernity, missionization and money.
