A Method for Documenting Hidden Structures on Shipwrecks: the case of Vasa and Warwick

As part of the programme for documenting and studying Vasa, a Swedish royal ship of 1628, raised from Stockholm harbour in 1961, the author was given the opportunity to develop and implement a method of documenting the hidden structure—the frames—of this three‐decker. The method proved transferable to work under water as tested on the wreck of the Warwick, a ship lost in Castle Harbour, Bermuda in 1619. This article describes the method.     

Legends of the Beauchamps' ancestors: the use of baronial propaganda in medieval England

From the early part of the eleventh century, legendary propaganda was generated by the Tosny family. The Warwickshire branch of the Beaumonts did likewise from the late twelfth century, their efforts culminating in the popular romance Guy of Warwick. Such material was designed to romanticize those activities of the families which had led to their acquiring landed power, and to reinforce a widespread acceptance of the status which they endeavoured to retain in face both of the growing powers of the monarchy, and of economic pressures. By contrast, the families of Beauchamp and Mauduit relied on growing royal power to enhance their position. Beauchamp dominance of Worcestershire through the hereditary enjoyment of the post of sheriff, and Manduit enjoyment of court influence through exercise of the hereditary office of chamberlain, obviated the need to generate a popular image, although both families attracted unfavourable notice in contemporary literature, generated by territorial or professional rivals. When the estates of all four families merged, at the end of the thirteenth century, to form the late medieval earldom of Warwick, the Guy image was consciously revived. John Rous, composing the Rous Roll in 1483, in order to glorify the lords of Warwick, suppressed unfavourable elements, both in this literature and in modern political history, while elaborating on others, reworking the material with the help of current literary themes.

The 14th-Century Rebuilding of the Collegiate Church of St Mary’s,Warwick

The 14th-century rebuilding of the collegiate church of St Mary’s by the earls of Warwick has received surprisingly little scholarly consideration, despite the status of its patrons and the distinctiveness of its architecture. This article uses drawings of the building before the fire of 1694, which destroyed its west end, together with the college’s extensive cartulary and other records, to reconstruct the 14th-century church. From this a timeline for the construction of the church is proposed. Regional, national and international stylistic precedents and antecedents are explored and used to test the validity of the ‘centre/periphery’ model of architectural change. The article concludes with a brief discussion of methodological insights drawn from the analysis.     

Post‐CO2 injection alteration of the pore network and intrinsic permeability tensor for a Permo‐Triassic sandstone

The aim of this study was to determine the process–structure–property relationships between the pre‐ and post‐CO₂ injection pore network geometry and the intrinsic permeability tensor for samples of core from low‐permeability Lower Triassic Sherwood Sandstone, UK. Samples were characterised using SEM‐EDS, XRD, MIP, XRCT and a triaxial permeability cell both before and after a three‐month continuous‐flow experiment using acidic CO₂‐rich saline fluid. The change in flow properties was compared to those predicted by pore‐scale numerical modelling using an implicit finite volume solution to the Navier–Stokes equations. Mass loss and increased secondary porosity appeared to occur primarily due to dissolution of intergranular cements and K‐feldspar grains, with some associated loss of clay, carbonate and mudstone clasts. This resulted in a bulk porosity increase from 18 to 25% and caused a reduction in mean diameter of mineral grains with an increase in apparent pore wall roughness, where the fractal dimension, D_f, increased from 1.68 to 1.84. All significant dissolution mass loss occurred in pores above c. 100 μm mean diameter. Relative dilation of post‐treatment pore area appeared to increase in relation to initial pore area, suggesting that the rate of dissolution mass loss had a positive relationship with fluid flow velocity; that is, critical flow pathways are preferentially widened. Variation in packing density within sedimentary planes (occurring at cm‐scale along the ‐z plane) caused the intrinsic permeability tensor to vary by more than a factor of ten. The bulk permeability tensor is anisotropic having almost equal value in ‐z and ‐y planes but with a 68% higher value in the ‐x plane (parallel to sedimentary bedding planes) for the pretreated sample, reducing to only 30% higher for the post‐treated sample. The intrinsic permeability of the post‐treatment sample increased by one order of magnitude and showed very close agreement between the modelled and experimental results.     

Syntectonic infiltration by meteoric waters along the Sevier thrust front,southwest Montana

Structural, petrographic, and isotopic data for calcite veins and carbonate host‐rocks from the Sevier thrust front of SW Montana record syntectonic infiltration by H₂O‐rich fluids with meteoric oxygen isotope compositions. Multiple generations of calcite veins record protracted fluid flow associated with regional Cretaceous contraction and subsequent Eocene extension. Vein mineralization occurred during single and multiple mineralization events, at times under elevated fluid pressures. Low salinity (T_m = ?0.6°C to +3.6°C, as NaCl equivalent salinities) and low temperature (estimated 50–80°C for Cretaceous veins, 60–80°C for Eocene veins) fluids interacted with wall‐rock carbonates at shallow depths (3–4 km in the Cretaceous, 2–3 km in the Eocene) during deformation. Shear and extensional veins of all ages show significant intra‐ and inter‐vein variation in δ¹⁸O and δ¹³C. Carbonate host‐rocks have a mean δ¹⁸O_V‐SMOW value of +22.2 ± 3‰ (1σ), and both the Cretaceous veins and Eocene veins have δ¹⁸O ranging from values similar to those of the host‐rocks to as low as +5 to +6‰. The variation in vein δ¹³C_V‐PDB of ?1 to approximately +6‰ is attributed to original stratigraphic variation and C isotope exchange with hydrocarbons. Using the estimated temperature ranges for vein formation, fluid (as H₂O) δ¹⁸O calculated from Cretaceous vein compositions for the Tendoy and Four Eyes Canyon thrust sheets are ?18.5 to ?12.5‰. For the Eocene veins within the Four Eyes Canyon thrust sheet, calculated H₂O δ¹⁸O values are ?16.3 to ?13.5‰. Fluid–rock exchange was localized along fractures and was likely coincident with hydrocarbon migration. Paleotemperature determinations and stable isotope data for veins are consistent with the infiltration of the foreland thrust sheets by meteoric waters, throughout both Sevier orogenesis and subsequent orogenic collapse. The cessation of the Sevier orogeny was coincident with an evolving paleogeographic landscape associated with the retreat of the Western Interior Seaway and the emergence of the thrust front and foreland basin. Meteoric waters penetrated the foreland carbonate thrust sheets of the Sevier orogeny utilizing an evolving mesoscopic fracture network, which was kinematically related to regional thrust structures. The uncertainty in the temperature estimates for the Cretaceous and Eocene vein formation prevents a more detailed assessment of the temporal evolution in meteoric water δ¹⁸O related to changing paleogeography. Meteoric water‐influenced δ¹⁸O values calculated here for Cretaceous to Eocene vein‐forming fluids are similar to those previously proposed for surface waters in the Eocene, and those observed for modern‐day precipitation, in this part of the Idaho‐Montana thrust belt.     

Mammalian Microfaunal Remains from Khonkho Wankane (Late Formative Period), Mollo Kontu (Middle Horizon Period) and Pukara de Khonkho (Late Intermediate Period) in the Bolivian Altiplano

Paleoecological and taphonomic analysis of the mammalian microfauna from three Bolivian altiplano sites is presented: Khonkho Wankane [Late Formative period; number of identified specimens (NISP) = 1019], Mollo Kontu (Middle Horizon period; NISP = 610) and Pukara de Khonkho (Late Intermediate period; NISP = 165). The following species, all of which are present in this region today, were identified: Akodon boliviensis (Bolivian grass mouse), Andinomys edax (Andean mouse), Auliscomys sublimis (Andean leaf‐eared mouse), Cavia porcellus (guinea pig/cuy), Chinchilla chinchilla (chinchilla), Ctenomys leucodon (white‐toothed tuco‐tuco), Eligmodontia puerulus (Andean gerbil mouse), Galea musteloides (common yellow‐toothed cavy), Lagidium viscacia (vizcacha), Neotomys ebriosus (Andean swamp rat),and Oligoryzomys destructor (destructive pygmy rice rat). Some direct human involvement with the deposition of some of the larger species (Cavia porcellus, Chinchilla chinchilla, Ctenomys leucodon and Lagidium viscacia) was noted, although C. porcellus was identified only from a single element from Mollo Kontu. Most deposition was likely due to natural in‐burrow deaths and other natural attrition of these species. No significant shift in environment during the occupation of these sites was detected.

Fractal analysis of veins in Permian carbonate rocks in the Lingtanchang anticline,western China

Statistical analysis of the thickness distribution of veins in the Lingtanchang structure, southern Sichuan basin, western China, indicates that vein thickness conforms to fractal character and a power‐law distribution, whereas various distributions of veins are indicated by both the spacing distribution and the C_v values. According to geometry and structure, the veins in the Lingtanchang structure can be divided into confined and through‐going veins. The statistical analyses show that confined intralayer veins are consistent with a power‐law distribution in thickness, with D_t values of 1.1–1.7 and a log‐normal distribution in spacing with C_v values of 0.8–0.9. The confined intra‐ to interlayer veins show D_t values of 1.0–1.3 and an exponential distribution in spacing, with C_v values of 0.9–1.0, indicating an unconnected vein network with weak ability for paleofluid flow. However, the through‐going veins show the lowest D_t values of 0.6–0.8 with a power‐law distribution in thickness and power‐law to exponential distribution in spacing with C_v values of 1.5–3.2. Differences in spacing distribution and in the thickness of veins can be explained by different stages of vein growth from confined to through‐going veins. Such processes are dominant with percolating cluster models, which significantly controls spatial distribution of veins and paleofluid flow, and therefore the reservoir conditions in the southern Sichuan basin.     

Swift and Erie: The Trials of an Ephemeral Landmark Case

Like jazz improvisation, the meaning of Swift v. Tyson was elusive. ¹ Justice Joseph Story's 1842 opinion concerning an important commercial‐law issue arose from a jury trial. ² When the creditor plaintiff appealed, counsel for the winning debtor raised as a defense Section 34 of the 1789 Judiciary Act. The federal circuit court disagreed about the standing of commercial law under Section 34. Although profound conflicts otherwise divided nationalist and states'‐rights proponents, the Supreme Court endorsed Story's commercial‐law opinion unanimously. ³ New members of the Court and the increasing number of federal lower‐court judges steadily transformed the Swift doctrine; after the Civil War it agitated the federal judiciary, elite lawyers, and Congress. ⁴ Asserting contrary tenets of American constitutionalism, the Supreme Court overturned the ninety‐six‐year‐old precedent in Erie Railroad v. Tompkins (1938). ⁵ The Swift doctrine's resonance with changing times was forgotten. The Court and the legal profession established, transformed, and abandoned the doctrine though an adversarial process and judicial instrumentalism. Although the policy of each decision reflected its time, Story's opinion was more consistent with the federalism of the early Constitution than was Erie. ⁶     

Iron mineralization and dolomitization in the Paran Fault zone,Israel: implications for low‐temperature basinal fluid processes near the Dead Sea Transform

Petrography, Eh‐pH calculations and the stable isotope composition of oxygen are used to interpret geochemical processes that occurred during iron oxide mineralization and dolomitization along the Menuha Ridge segment of the Paran Fault, southern Israel, adjacent to the Dead Sea Transform (DST). Iron mineralization is strongly localized in the fault zone as ferruginous lenses, whereas Fe dolomitization spreads laterally into the Cenomanian‐Turonian carbonate host rock as stratabound beds. The average oxygen isotope fractionation between syngenetic quartz and iron oxides in the ferruginous lenses gives a temperature of 50 ± 10°C and δ¹⁸O SMOW water = ?3.5‰; consistent with an origin from metalliferous groundwater flow in the sedimentary basin. Ferroan dolomite initially formed under strongly reducing conditions, but this was followed by oxidation and pseudomorphic replacement of the dolomite by a mesh of fine‐grained iron oxides (simple zoned dolomites). This cycle of ferroan dolomite formation and replacement by iron oxides was repeated in complex zoned dolomites. Dolomite oxygen isotope compositions fall into two groups: a high δ¹⁸O group corresponding to the simple zoned dolomites and non‐ferroan dolomites and a low δ¹⁸O group corresponding to the complex zoned dolomites. Water‐rock calculations suggest that the epignetic dolomites formed under fluid‐buffered conditions: the high δ¹⁸O group are indicated to have formed at temperatures of ca. 25°C for waters with δ¹⁸O = ?4 to 0‰; the low δ¹⁸O complex zoned dolomites at 50–75°C for waters with the same isotopic composition. A kinetic calculation for a complex zoned dolomite‐bearing bed indicates that dolomitization must have occurred at high values of the dolomite saturation index. This requirement for high Mg supersaturation and the indication that epigenetic dolomitization is more protracted in stratigraphically deeper formations located closer to the DST is consistent with models proposing that Mg‐rich solutions originated in the Dead Sea Rift.     

A STUDY ON LATE MEDIEVAL TRANSPARENT‐GLAZED POTTERY AND ARCHAIC MAJOLICA FROM ORVIETO (CENTRAL ITALY)*

Nineteen samples of medieval transparent‐glazed pottery and archaic majolica from Orvieto (central Italy) were studied. They were classified by archaeological criterion as follows: five transparent‐glazed fragments with green and brown decorations (first half of the 13th century), eight green transparent‐glazed fragments (13th century) and six tin‐glazed fragments with green and brown decorations (second half of the 13th century). SEM–EDX, XRD (the Rietveld method) and XRF were used to characterize the chemical and mineralogical compositions both of the bodies and the coatings. In all of the samples, the paste is Ca‐rich with CaO contents as high as 13–20 wt%. The mineralogical composition is compatible with a firing temperature of about 950°C, which is the typical temperature reached in a wood kiln. No difference was observed between the bodies of transparent‐ and tin‐glazed pottery. In the case of transparent glazes, the burial conditions lead to heavy weathering of the samples. However, on the basis of the analyses carried out in non‐weathered areas, the typical composition is PbO 55–65 wt%, SiO₂31–35 wt%. In tin glazes, the tin is scattered on the mass of the glaze as SnO₂crystals with a concentration of 7–14 wt%. Concerning the decorations, it is established that the green colour is due to the presence of copper, while manganese is responsible for the brown colour. These pigments, which represent the typical colours of ‘archaic majolica’, are spread through the glaze homogeneously, apart from one case in which there is clear evidence of manganese oxide crystals.     

Illustrations of Medieval Manners and Costume from Original Documents

The Coningesby family connection with Guy of Warwick is recorded in a pedigree of the family in the Lincolnshire Record Office. The will of Sir Henry Coningesby, knight, indicates that he built the present house at North Mymms Park, probably in the 1580s. It is suggested that the ‘Warwick’ worthy depicts Sir Henry's thirteenth-century ancestor, Sir Roger Coningesby, knight, Steward of the house to Guy of Warwick. There was a connection by marriage between the house at North Mymms, Hertfordshire and Nether Hall, Essex, where similar wall paintings had existed. The association between the Coningesby family, when at the Manor of Weld and the Cutts family, when at Salisbury Hall, both in the parish of Shenley, Hertfordshire, probably accounts for the similarity of the frieze in the Oak bedroom and the frieze in Childerley Hall, Cambridgeshire.     

The Story of Koula: music and nationhood in Greece

The Story of Koula, one of the Marshall Plan films, was made in Greece in 1951. It neatly exemplifies the capacity of Europe to ‘talk back’ to the USA within the framework of cultural aid programmes. And as such it can introduce a little‐explored topic: the politics of the avant‐garde in Greece in the post‐Civil War years and in particular the role of US cultural aid. This post‐war perspective throws light on the better‐known National School associated above all with Manolis Kalomiris, who dominated Greek music and musical life in the interwar period. The second part of this paper scrutinises the agenda and achievements of the Kalomiris circle, and that in turn enables useful generalisations about romantic nationalism in music. The third part of the paper reflects on the pre‐World War I achievements of Heptanesian traditions, again caught between singularities and dependencies.

Whence nationalism?

ABSTRACT. There is widespread agreement that nationalism emerged in the historical fountainheads of modernity, and was subsequently diffused outwards. Contrary to that, there is a long standing view that nationalism precedes modernity even in the broadly accepted cradles of both modernity and nationalism, such as England or France, neither of which was modern when it engendered nationalism. Besides, some emergent nationalisms ran concurrent with their English or French counterparts, with little evidence of having been spawned by diffusion. Such early or protonationalisms often sprang from resistance to foreign conquest, putting in doubt the invention‐diffusion hypothesis. I am therefore suggesting that nationalism has not emerged in few societies, but in many, and that it was engendered by social interactions, not by a particular social formation. While nationalism emerges within society, its genesis occurs in‐between social groups and societies, making it a product of their interactions. That makes it u‐topic, its cradles socially diverse, and its conception interactional, not gestational.     

Invasion of a karst aquifer by hydrothermal fluids: evidence from stable isotopic compositions of cave mineralization

Mineral deposits in the Cupp‐Coutunn/Promeszutochnaya cave system (Turkmenia, central Asia) record a phase of hydrothermal activity within a pre‐existing karstic groundwater conduit system. Hydrothermal fluids entered the caves through fault zones and deposited sulphate, sulphide and carbonate minerals under phreatic conditions. Locally, intense alteration of limestone wall rocks also occurred at this stage. Elsewhere in the region, similar faults contain economic quantities of galena and elemental sulphur mineralization. Comparisons between the Pb and S isotope compositions of minerals found in cave and ore deposits confirm the link between economic mineralization and hydrothermal activity at Cupp‐Coutunn. The predominance of sulphate mineralization in Cupp‐Coutunn implies that the fluids were more oxidized in the higher permeability zone associated with the karst aquifer. A slight increase in the δ³⁴S of sulphate minerals and a corresponding δ³⁴S decrease in sulphides suggest that partial isotopic equilibration occurred during oxidation. Carbonate minerals indicate that the hydrothermal fluid was enriched in ¹⁸O (δ¹⁸O_SMOW ～ + 10‰) relative to meteoric groundwater and seawater. Estimated values for δ¹³C_DIC (δ¹³C_PDB ～ ? 13‰) are consistent with compositions expected for dissolved inorganic carbon (DIC) derived from the products of thermal decomposition of organic matter and dissolution of marine carbonate. Values derived for δ¹³C_DIC and δ¹⁸O_water indicate that the hydrothermal fluid was of basinal brine origin, generated by extensive water–rock interaction. Following the hydrothermal phase, speleothemic minerals were precipitated under vadose conditions. Speleothemic sulphates show a bimodal sulphur isotope distribution. One group has compositions similar to the hydrothermal sulphates, whilst the second group is characterized by higher δ³⁴S values. This latter group may either record the effects of microbial sulphate reduction, or reflect the introduction of sulphate‐rich groundwater generated by the dissolution of overlying evaporites. Oxygen isotope compositions show that calcite speleothems were precipitated from nonthermal groundwater of meteoric origin. Carbonate speleothems are relatively enriched in ¹³C compared to most cave deposits, but can be explained by normal speleothem‐forming processes under thin, arid‐zone soils dominated by C4 vegetation. However, the presence of sulphate speleothems, with isotopic compositions indicative of the oxidation of hydrothermal sulphide, implies that CO₂ derived by reaction of limestone with sulphuric acid (‘condensation corrosion’) contributed to the formation of ¹³C‐enriched speleothem deposits.     

Modeling of hydrogen production by serpentinization in ultramafic‐hosted hydrothermal systems: application to the Rainbow field

The production of hydrogen by serpentinization in ultramafic‐hosted hydrothermal systems is simulated by coupling thermodynamic and dynamic modeling in the framework of a thermo‐hydraulic single‐pass model where a high‐temperature hydrothermal fluid moves preferentially through a main canal of high permeability. The alteration of ultramafic rocks is modeled with a first‐order kinetic formulation, wherein the serpentinization rate coefficient, K_r, takes the form: K_r = A exp(?α(T ? T₀)²). In this formulation, α determines the temperature range of the reaction and T₀ is the temperature at which the serpentinization rate reaches its maximum. This model is applied to the Rainbow hydrothermal system, which is situated on the Mid‐Atlantic Ridge, and characterized by a high temperature, a high mass flux, and a very high hydrogen concentration. The results show that a first‐order kinetic law gives a useful representation of the kinetics of serpentinization. The estimated value for the parameter A in the temperature‐dependent formulation of the serpentinization rate coefficient lies in the range (1–5) × 10^?11 s^?1. This effective parameter is several orders of magnitude lower than the values obtained from small grain‐size experiments, but in agreement with other published modeling studies of natural systems. Numerical simulations show that the venting site is able to produce the observed high concentration of hydrogen during the whole continuous lifetime of the Rainbow site.     

Vegetation,land, and wood use at the sites of Bat and Al‐Khashbah in Oman (fourth–third millennium BC)

About 4200 charcoal fragments have been identified from the fourth‐ to third‐millennium BC archaeological sites of Bat and Al‐Khashbah in order to gain an understanding of plant resources available at the sites. Acacia sp., Ziziphus sp., and Tamarix sp. were the main taxa identified at both sites and indicate a similar vegetation composition as today. Phoenix sp. (date palm) charcoal also has been found at both sites. Whereas the cultivation of date palm for the 2700–2300 BC layers from Bat was likely, given other circumstantial evidence (i.e. local cereal cultivation and floodwater irrigation), it is unclear whether date palm was cultivated at Al‐Khashbah. Especially for the older periods (3300–2700 BC) it is possible that nomadic pastoralists were exploiting and/or managing wild date palms. The find of Avicennia marina at Al‐Khashbah indicates long‐distance contacts with the coast.
