Palaeo‐otology of cholesteatoma

A cholesteatoma is a collection of dead epithelial cells in the ear which becomes infected with low‐grade pathogenic microorganisms. The lesion tends to cause resorption of the surrounding bone, which potentially permits its recognition in skeletal remains. Cholesteatoma may occur in the middle or the outer ear. Using two examples of cholesteatoma in skeletal remains from British archaeological sites, the differential diagnosis of cholesteatoma from other aural diseases is demonstrated. Some of the differences in bony lesions caused by middle ear and external ear canal cholesteatoma which may enable the two to be distinguished in palaeopathological specimens are discussed. Attention is drawn towards the importance of making this distinction in ancient skeletal remains; middle ear and external ear canal cholesteatoma have a different array of causes and very different impacts upon health status.

The Leamington Scow: the excavation of historic structures and canal vessel at Leamington Wharf,Union Canal,Edinburgh

Abstract

Archaeological investigations were carried out at Leamington Wharf on the Union Canal in Fountainbridge, Edinburgh. The remains of a stone quay, wooden platforms and staging, a rope walk and a canal vessel were investigated prior to redevelopment of the site for housing. The combination of archaeological excavation and historical research has illuminated the development of this former canal basin at the terminus of the Union Canal, and provided a rare opportunity to study the remains of a canal vessel likely to date from the early to mid 19th century. A scaled model of the vessel was commissioned as part of the project and will be submitted to the local museum service as a record.     

Interpreting Medieval Inter-tidal Features at Weelie’s Taing on Papa Westray,Orkney, NE Scotland

Investigation of the inter-tidal heritage of the Orkney Islands is used to interpret a previously perplexing complex at Weelie’s Taing on Papa Westray. The study revealed a previously unknown type of harbour since identified in several locations around Orkney. Situated in exposed environmental situations, shelter is formed by an ‘ayre’, a type of spit that encloses a loch, and which has been used historically as a landing place or crossing of the inter-tidal zone. A complex landing area, pier, tower and ship-blockage suggest Weelie’s Taing was used as a harbour. Important fishing grounds exploited since the Neolithic are nearby, and Papa Westray was the site of water-focussed religious communities. It is suggested that Weelie’s Taing was in use in the medieval period when Papa Westray was less isolated than today with the presence of ecclesiastical communities and situation on the Orkney-Shetland route.     

A Case of Ancient Bladder Stones from Oluz Höyük,Amasya, Turkey

A biological object was recovered from the pelvic region of an adult woman coded to SK13 unearthed from Oluz Höyük in Amasya, Turkey. The skeleton was dated to the medieval period on the basis of the burial customs and the calibrated ¹⁴C dates. The find was identified as a bladder stone on morphological, radiographic and chemo‐analytical grounds with the help of X‐ray diffraction, polarised energy dispersive X‐ray fluorescence spectroscopy, confocal Raman spectroscopy, and microscopic techniques. The mineralogical composition of urinary stone was found to be as calcium phosphate (apatite). Bladder stone disease is endemic in poor agricultural regions where the typical diet is mostly based on grain carbohydrate consumption with scarce intake of animal protein.

Non‐specific indicators of stress and their association with age at death in Medieval York: Using stature and vertebral neural canal size to examine the effects of stress occurring during different periods of development

Selective mortality can occur towards individuals who survive episodes of physiological stress, such as disease and malnutrition, during development. The skeletal elements affected depend on the timing of these stressful episodes. Studying multiple non‐specific indicators of stress can show which periods of development were affected and whether certain periods can be linked with selective mortality. To examine this method a preliminary study of 61 adult individuals from the Medieval population of Fishergate House, York was undertaken to examine small vertebral neural canal size and reduced adult stature. Previous studies have shown that selective mortality occurs towards individuals who display these non‐specific indicators of stress. Statistical analysis showed that small transverse neural canal diameter was significantly associated with early adult mortality for males and females and there was evidence of selective mortality towards females with reduced stature. This suggests that individuals who died in early adulthood experienced health insults during late childhood which stunted VNC growth but males in particular were not significantly affected by health insults after this age as they achieved a normal adult stature. Therefore it appears that health insults which occurred during late childhood had a greater influence on adult health in the Fishergate House population. This method could be expanded to provide more detailed information by using a greater variety of non‐specific indicators of stress which will allow more specific periods of development to be investigated.

Dedicated Followers of Fashion? Bioarchaeological Perspectives on Socio‐Economic Status,Inequality, and Health in Urban Children from the Industrial Revolution (18th–19th C), England

The 18th and 19th centuries in England were characterised by a period of increasing industrialisation of its urban centres. It was also one of widening social and health inequalities between the rich and the poor. Childhood is well‐documented as being a stage in the life course during which the body is particularly sensitive to adverse socio‐economic environments. This study therefore aims to examine the relationship between health and wealth through a comprehensive skeletal analysis of a sample of 403 children (0–17 years), of varying socio‐economic status, from four cemetery sites in London (c.1712–1854). Measurements of long bone diaphyseal length, cortical thickness, vertebral neural canal size, and the prevalence of a range of pathological indicators of health stress were recorded from the Chelsea Old Church (high status), St Benet Sherehog (middle status), Bow Baptist (middle status), and Cross Bones (low status) skeletal collections. Children from the low status Cross Bones site demonstrated deficient growth values, as expected. However, those from the high status site of Chelsea Old Church also demonstrated poor growth values during infancy. Fashionable child‐care practices (e.g. the use of artificial infant feeds and keeping children indoors) may have contributed to poor infant health amongst high status groups. However, differing health risks in the lower status group revealed the existence of substantial health inequality in London at this time. © 2016 The Authors International Journal of Osteoarchaeology Published by John Wiley & Sons Ltd.     

An Early Portuguese Mariner's Astrolabe from the Sodré Wreck‐site,Al Hallaniyah,Oman

A unique leaded‐gunmetal disc decorated with iconic Portuguese markings was recovered in 2014 during archaeological excavations at the Sodré shipwreck site in Al Hallaniyah, Oman. Initially the identity and function of the disc was unknown, although it did possess characteristics suggesting it could be an astrolabe. Laser imaging of the disc post conservation revealed regular scale marks on the limb of its upper right quadrant. Accurate digital measurements of the marks show them to be graded at close to 5‐degree intervals, thus confirming the identity of the disc as a mariner's astrolabe and the earliest known example discovered to date.     

Establishing Stage‐Discharge Relationships in Multiple‐Channelled,Ephemeral Rivers: a Case Study of the Diamantina River,Australia

The method for deriving a stage‐discharge relationship has a significant impact on the shape of the river's rating curve. We compare rating curves for a single gauging station on a mutiple‐channelled river in Australia compiled using three different methods – the Urban Runoff and Basin Systems (URBS) rainfall‐runoff model, an empirically‐based velocity‐area method, and the predictive Hydrologic Engineering Centre‐River Analysis System (HEC‐RAS) computer model. The rainfall‐runoff model was found to predict lower discharges for stage heights over 3.5 m than both the empirically‐based velocity‐area method and the HEC‐RAS model. The empirically‐based velocity‐area model predicts similar discharges to the rainfall‐runoff model for stage heights less than 3 m but much higher discharges for larger flood events. The HEC‐RAS model predicts higher discharges than both other rating curves at all stage heights probably due to under‐estimation of the impact of surface roughness on flow velocity. The three models are discussed with particular reference to their use on multiple‐channelled rivers.     

Mining Archaeology and Micro‐Raman Analysis Associated with ESEM‐EDX: Toward a Chrono‐Spatial Definition of Ore Consumption in a Pyrenean Medieval Workshop, 14th–16th Centuries

The rapid expansion of non‐ferrous metallurgy in the late Middle Ages (14th–15th centuries) enhanced ore demand, which was supported by mining intensification. Metallurgical workshops developed various supply strategies based on geological, political and economic constraints. This is particularly true for the Pyrenean multi‐metals workshop of Castel‐Minier (Ariège, France), where recent excavations unearthed an exceptional corpus of non‐ferrous ores. A specific analytical methodology combining micro‐Raman spectroscopy and environmental scanning electron microscopy with energy dispersive X‐ray (ESEM‐EDX) was set up to study these artefacts. This composite methodology permitted the fast characterization of both mineral and gangue as well as a discussion of their economic potential. Ores identified were compared with ancient mines in neighbouring mining districts in order to sketch a geography of the mineral resources available to medieval metallurgists. Moreover, a chrono‐stratigraphic study of ore distribution in Castel‐Minier revealed the supply strategies, technological choices as well as spatializing of copper and lead metallurgies.     

A SPECTROSCOPIC INVESTIGATION OF PIGMENT AND CERAMIC SAMPLES FROM COPÁN,HONDURAS*

A combination of micro‐Raman spectroscopy, micro‐infrared spectroscopy and SEM–EDX was employed to characterize decorative pigments on Classic Maya ceramics from Copán, Honduras. Variation in red paint mixtures was correlated with changing ceramic types and improvements in process and firing techniques. We have confirmed the use of specular hematite on Coner ceramics by the difference in intensities of Raman bands. Different compositions of brown paint were correlated with imported and local wares. The carbon‐iron composition of the ceramic type, Surlo Brown, was confirmed. By combining micro‐Raman analysis with micro‐ATR infrared and SEM–EDX, we have achieved a more comprehensive characterization of the paint mixtures. These spectroscopic techniques can be used non‐destructively on raw samples as a rapid confirmation of ceramic type.     

The Sail of the Swedish Merchantman Jeanne‐Élisabeth,Wrecked off Montpellier,France, in 1755

A folded sail was found stowed in the hold of the Swedish‐registered merchantman Jeanne‐Élisabeth, which ran aground off Montpellier in a storm in 1755. Surviving sails from any period are rare. The structure of the recovered portion of sail and its associated cordage is described and discussed in the context of differing traditions and technological evolutions of the period. Recovery, recording and initial conservation techniques are discussed in an appendix . © 2011 The Authors     

Application of Landsat satellite imagery to monitor land‐cover changes at the Athabasca Oil Sands,Alberta, Canada

A major advantage of satellite remote sensing is that the imagery acquired provides a synoptic view of the landscape. Thus, repeat coverage by the satellite on a regular basis permits the detection of changes in land‐cover over time. This study demonstrates the application of remote sensing technology to the monitoring of mining activities at the Athabasca Oil Sands region of Alberta, Canada. First, we describe the techniques used to match a time sequence of Landsat imagery, both spatially and spectrally, to ensure that the spectral changes through time are due to land‐cover variations. A series of spectral trajectories were then extracted to assess changes in land‐cover through time. Secondly, a land‐cover classification was produced from the baseline 1984 imagery and, using historic and future mine extents, the classification was analyzed to determine the proportion of each land‐cover type affected through development. Results of the analysis indicate that since 1984 there has been a larger reduction in mixedwood dense and broadleaf vegetation classes than mixedwood sparse or dense conifer stands in the area. Based on the delineations of mine‐site activity, the area of woodland and wetland habitat subject to development has increased from approximately 2,520 hectare (ha) in 1984 to 32,930 ha in 2005.     

“The Cockroaches of Canada”: French‐Canada,Immigration and Nationalism,Anti‐Catholicism in English‐Canada, 1905–1929

This article examines the central influence of anti‐Catholicism upon English‐Canadian nationalism in the first third of the twentieth century. Anti‐Catholicism provided an existing rhetorical and ideological tradition and framework within which public figures, intellectuals, Protestant church leaders and other Canadians communicated their diverse visions of an ideal Canada. The study of anti‐Catholicism problematises the rigid separation that many scholars have posited between a conservative ethnic nationalism and a progressive civic nationalism. Often times these very civic values were inextricable from a context of Britishness. In addition, anti‐Catholicism was not simply about theological differences between Protestants and Catholics. Instead this theological thread often intersected with the perceived socio‐political problems that Catholics and Catholicism posed. Hostility to Catholicism was not limited only to fraternal organisations such as the Orange Order; indeed the importance of anti‐Catholicism as a component of Canadian nationalism lies in its presence across the political and intellectual spectrum. Catholicism was perceived to inculcate values antithetical to British traditions of freedom and democracy.     

Benign mandibular tumours: Two case studies from the Maya lowland site of Tikal,Guatemala

This study presents a differential diagnosis of benign mandibular tumours identified in two adult burials from the precontact Maya city of Tikal, Guatemala. Both individuals were recovered from domestic structures that date to the Late Classic Period (AD 550–850). The osseous growths were interpreted as probable benign tumours based on evidence of localised growth, a circumscribed border, a dense texture and a lack of osteolytic activity or spiculate bone formation. Burial PTP‐026A is a middle adult (35–50 years) of indeterminate sex with evidence of a small dense, circular mass extending laterally from the right mandibular corpus. Macroscopic and radiographic assessment of this lesion provided a diagnosis of osteoma, a true neoplasm, or alternately, hyperplasia (e.g. exostosis) or hamartoma, which are not true neoplasms. Burial PTP‐017 is a probable young adult female (20–35 years) with a large osteoblastic lesion on the right anterior mandibular corpus. This dense, bony mass extends from the anterior margin of the mental canal, and shows a distinct boundary from the adjacent trabecular and cortical bone. The growth of the osseous mass displaced the right first premolar anteriorly. Radiographic assessment showed the presence of dense, radiopaque material, indicating significant calcification. This suggested a likely fibro‐osseous origin for this lesion, with a probable diagnosis of ossifying fibroma, or possibly osseous dysplasia. Although not definitive, our differential diagnosis was able to exclude a number of neoplastic and non‐neoplastic conditions that affect the jaws. This study provides the first reported cases of possible benign mandibular tumours in the ancient Maya. Copyright © 2009 John Wiley & Sons, Ltd.     

Wives,Children … Husbands: Supporting Roles

In 1965, Hugo L. Black asked his wife, Elizabeth, to host a dinner party. The purpose: to help him persuade Carolyn Agger, wife of Washington attorney Abe Fortas, to allow her husband to accept President Lyndon B. Johnson's offer of a seat on the Supreme Court. A tax lawyer at the same firm as Fortas, Agger was displeased that the move would mean a big cut in his salary; she thought he should spend a few more years in his lucrative private practice before becoming a judge. After all, he was only fifty‐five. Elizabeth Black described the tense occasion in a diary entry:     

Recent Excavation and Recording at the New Neolithic Rock Art Site of Vallée Aux Noirs,Buthiers (Seine‐et‐Marne,France)

Following the exceptional discovery of Neolithic engravings on a boulder at Vallée aux Noirs in the Fontainebleau forest, south of Paris, an excavation trench was opened in order to access the buried part of the decorated rock panel and explore the stratigraphic context of the artwork. A palaeosol was found two metres below the modern ground level, underneath multiple layers of sterile sandy soil forming a very compact sequence from which only one archaeological artefact was recovered – an Iron Age fibula (c.200–300 BC). Dating of the palaeosol was attempted through two different methods: AMS dates from charcoal suggest a significant span from the Early Bronze Age to the Iron Age, while two more consistent OSL dates point to formation of the palaeosol during the Late Neolithic (3500–3000 cal BC). The entire engraved rock surface (16 m²), including its buried part, was fully recorded. Four main semiotic groups were identified: a typical fifth‐millennium crook‐hafted axe with a ring, two boats with steering oars, and a central, very tall human figure dominating the composition from its 3.5‐metre height.     

Arbeit und Zeit,Körper und Uhr: Die Konstruktion von ‚effektiver’︁ Arbeit im ‚Scientific Management’︁ des frühen 20. Jahrhunderts

The concept ‚Scientific Management’︁ was invented in 1910 for what was then called the ‚Taylor‐system’︁ of shop management. Frederick W. Taylor had developed his system to eliminate the “waste of human effort” mainly by “time study”, the analysis of the work of “first‐class workman” with a stop‐watch and the synthesis of standard times for given tasks which make the “waste” of effort visible and measurable. A reading of Karl Marx's work shows the “paradigm of productivity” governing mid‐century discussion of the value of labor. Time is a central element in the valuation of industrial labour, but only with Taylor the precision of the stop‐watch is introduced to observe and control the productivity of the body of the worker. As disciples of Taylor Frank and Lillian Gilbreth introduced motion studies and micromotion studies into Scientific Management. Their analysis of the motion of workers, technically assisted by high‐speed watches and cameras, goes beyond the surface‐observation of the first‐class workman to enable the design of efficient motion. The body of the worker is represented in lines of light and tables of data. The objects of desire are the time‐lines of efficiency and productivity. In both cases, Taylor and the Gilbreths, various observations further lead to the conclusion that science and schooling are an important historical background to the rise of Scientific Management that deserves closer inspection.     

Pyrite–sulfosalt reactions and semimetal fractionation in the Chinkuashih,Taiwan, copper–gold deposit: a 1 Ma paleo‐fumarole

The mineralized fracture system that underlay paleo‐fumarole field at Chinkuashih, Taiwan has been exposed by copper–gold mining to depths of about 550 m below the paleo‐surface. Its mineralogy and systematic variations in metal and semimetal (Fe, Cu, As, Sb, Bi, Hg, Cd, Sn, Zn, Pb, Se, Te, Au, Ag) concentrations provide insights into the chemical responses of a magmatic‐vapor phase as it expands through fracture arrays to the surface and discharges as fumaroles associated with more extensive solfatara. At Chinkuashih, following initial sealing of the fractures by silica‐alunite alteration, brittle failure reestablished discharge from an underlying reservoir of magmatic vapor. Crystalline pyrite was deposited first in the fractures and was succeeded and replaced by ‘enargite’ (Cu₃(As,Sb)S₄) as sulfosalt encrustations (‘sublimate’) on fracture surfaces and in extensional cracks. Subsequent recrystallization resulted in complex exsolution intergrowths with antimony fractionation to the evolving crystal–vapor interface. Heavy metal fractionation between sulfosalt and vapor enriched the vapor phase in heavy metals that subsequently precipitated as complex Bi–Hg–Sn sulfosalts in discrete areas (paleo‐fumaroles) close to the paleo‐surface in a manner analogous to modern‐day fumaroles on active volcanoes such as Vulcano, Italy. As in similar paleo‐fumaroles (e.g., El Indio, Chile and Lepanto, Philippines), the most characteristic reaction sequence is the partial replacement of the early pyrite by enargite and Fe‐tennantite. It is proposed that this reaction tracks the decrease in the pressure of the underlying magmatic‐vapor reservoir because of the sustained discharge of vapor to the surface.     

Origin of dolomites in the Cambrian (upper 3rd‐Furongian) formation,south‐eastern Sichuan Basin,China

The origin of large‐scale ancient dolomite is one of the most hotly debated topics in sedimentology. The Loushanguan group of the upper 3rd‐Furongian Cambrian series on the south‐eastern margin of the Sichuan Basin consists of numerous dolomites, and the origins of these dolomites have never been reported previously although they are probably good hydrocarbon reservoirs. Based on a systematic analysis of petrology, fluid inclusions, carbon and oxygen isotopes, trace elements and rare earth elements (REEs), this study provides some unique insights into the origins of the dolomites. Four dolomite types have been identified in the study area: dolomicrite, fabric‐retentive oolitic dolomite, fabric‐obliterative dolomite and saddle dolomite cement. In the dolomicrite and fabric‐retentive oolitic dolomite, high Sr contents (with respect to the fabric‐obliterative dolomite) and the lack of two‐phase aqueous inclusions suggest that they formed at shallow‐to‐intermediate burial depths at low temperatures (<50–60°C). Carbon and oxygen isotopes and seawater‐like REE+Y characteristics of the dolomicrite and fabric‐retentive oolitic dolomite indicate that the dolomitizing fluids were evaporated seawater or slightly modified seawater. The obliteration of the original sedimentary fabric and relatively low δ¹⁸O and Sr values compared to the fabric‐retentive dolomite indicate that fabric‐obliterative dolomite formed at intermediate‐to‐deep burial diagenesis. The chemical composition approaches pure dolomite and the REE+Y characteristics are similar to those of the fabric‐retentive dolomite, indicating that the fabric‐obliterative dolomite was formed due to the recrystallization of the previously formed fabric‐retentive dolomite at elevated burial depths and temperatures. High fluid inclusion homogenization temperatures (115–150°C), low δ¹⁸O values, nonplanar‐a crystals and seawater‐like REE+Y characteristics suggest that saddle dolomite cement formed by reprecipitation of dolomite that related to seawater‐driven and deep burial fluid. In the study area, dolomicrite and fabric‐retentive oolitic dolomite may have been formed by penecontemporaneous or seepage‐reflux dolomitization during early‐stage diagenesis. Subsequently, during progressive burial, most of the fabric‐retentive dolomite was converted into fabric‐obliterative dolomite by recrystallization. This study confirms that fabric‐obliterative dolomite was the main dolomite type, and although deeply buried, these Cambrian dolomites most likely have preserved coeval seawater geochemical signals.     

Khirbat al‐Mana‘iyya: an early Islamic‐period copper‐smelting site in south‐eastern Wadi ‘Araba,Jordan

Recent excavations in south‐eastern Wadi ‘Araba in Jordan have revealed the first early Islamic‐period copper‐smelting site known in the eastern side of the valley, which extends south of the Dead Sea to the Gulf of ‘Aqaba. Five test pits were excavated in 2012 at Khirbat al–Mana‘iyya, a prominent copper‐smelting camp in south‐eastern Wadi ‘Araba, Jordan. The results of these excavations demonstrate that the site was primarily active in the seventh–ninth century AD. Its distance from the copper sources of south‐west ‘Araba suggests that its location was chosen based on proximity to wood and water resources, rather than copper ore deposits. The discovery that the site dates to the early Islamic period has implications for previous and future work in south‐east ‘Araba. In particular, it challenges the common—until now—view of the region as virtually devoid of settlement during this period.
