Late medieval shipbuilding in Catalonia followed the Mediterranean trend in adopting a frame‐first shipbuilding principle with planking placed edge‐to‐edge. The predetermination of frame shapes using moulds had modified the construction process, as seen in the 11th‐century Serçe Liman? vessel with the use of a series of moulds, and 13th‐century Culip VI, with the use of a master mould, rising square and rule. Between the 13th and 15th centuries all known Mediterranean shipwrecks were built using the master‐mould method, but other factors caused variation in the construction process—not the principle—as exemplified by the 14th‐century Les Sorres X built with two overlain keel timbers.  相似文献

This article reports on the artefacts and environment of marine ballast and pottery sites identified through inter‐tidal and underwater survey around Kilwa, Tanzania, one of the most important medieval sultanates along the east African coast. An inter‐tidal site on the limestone fringing reef on the approaches to Kilwa Kisiwani Harbour and an underwater site within the harbour have been dated from associated pottery to c.8th–10th century and the 13th–16th century respectively. The presence of exotic basalt ballast is discussed as an indicator of wreck‐sites.  相似文献

The Michelet necropolis in Lisieux, France, dating to the late Roman and Merovingian period, comprises of a large number of well‐preserved subadult remains offering a unique opportunity to better understand childhood trauma in the past. The focus of this study was to determine the amount, type and mechanisms of trauma evidenced in subadults from the 4th–8th century AD, and explore potential circumstances surrounding the trauma. The remains of 109 subadults from the Michelet necropolis were examined for the presence of cranial and post‐cranial trauma. Three individuals exhibited perimortem trauma, one individual had an antemortem cranial injury, and no cases of post‐cranial trauma were identified. Cranial trauma affected 4.1% of children with observable cranial remains (N  = 4/97). The children affected were young (2–7 years old), making it unlikely that they would have participated in militaristic activities. Based on the location, morphology and mechanism of injury identified, it is likely that the perimortem injuries sustained by three children were not accidental. The presence of a number of cranial injuries from this site may be related to increased stress in the community related to the decline of the Roman Empire in Gaul, possible raiding barbarian groups during the 4th–5th centuries, or stresses related to the Gallic aristocracy solidifying political powers in northern Gaul during the 5th–7th centuries AD. The consideration and inclusion of childhood trauma in bioarchaeological analyses allows for a more detailed and in‐depth understanding of violence and childhood in the past.

In 1973, while recovering copper cargo from a 20th‐century ship wrecked off the Ponta do Leme Velho on the south‐east side of Sal Island, Cape Verde, explosives revealed an earlier ship cargo with dozens of Portuguese faience plates and bowls, glass beads and metal objects, including buckles, ammunition and copper manillas. The assemblage, including the ceramics and a marked silver tastevin, provide a site date between 1680 and 1700. The research presented here is a result of collaboration between CPAS and the authors in 2008 to analyse this assemblage in the context of late 17th‐century maritime trade.  相似文献

The laser ablation ICP–MS transect of a speleothem from GB Cave, close to Charterhouse, Mendip Hills, UK, records Pb variations over the past 5 ka. The speleothem record correlates well with the known historical record of lead mining in the district, the principal features of which include: the Roman lead mining peak; the Dark Ages cessation; gradual, episodic revival up to the late 16th century peak; the 17th century collapse and subsequent recovery; and the final short‐lived burst at the end of the 19th century. This correlation supports the assumption that the pre‐Roman lead record also derives from local mining. Thus, this record is the first example of quantifying ancient human mining activity through trace element signature of a speleothem. This record also provides the first solid evidence of significant pre‐Roman mining activity in the Charterhouse region, and the first solid dating of that activity. This pre‐Roman mining can be divided into three main peaks dated to 1800–1500 bc , 1100–800 bc and 350–0 bc .  相似文献

Medieval pottery from excavations at Novo Brdo, Serbia, an important mining and trading centre during the 14th and 15th centuries, was investigated by a combination of optical microscopy, inductively coupled plasma – optical emission spectrometry, Fourier transform infrared, micro‐Raman and energy‐dispersive X‐ray fluorescence spectroscopy and X‐ray powder diffraction methods in order to determine its composition and firing temperature. The samples investigated were made of medium‐ to coarse‐grained, non‐calcareous clay, by a relatively well‐controlled firing procedure in an oxidizing atmosphere. The firing temperature was estimated to be 850–950°C. The similarity between the chemical composition of the investigated pottery and the local raw clay, combined with the outward appearance and the archaeological findings, indicate domestic production. The pottery is covered with the transparent lead‐rich glaze. Iron and copper were used as colourants.  相似文献

By combining underwater survey with formal and compositional study of ceramics, recent work at Burgaz (south‐west Turkey) reveals a late 6th‐ or 7th‐century assemblage of wine and perhaps other agricultural products carried in LR1 and LR2‐related amphoras. Representing various south‐east Aegean and likely Cilician producers, the mixed cargo aboard this probable shipwreck offers insights into the complex dynamics of seaborne distribution at the end of Antiquity. This brief study also underscores the need for documentation in underwater survey of amphora forms and fabrics, particularly those from a period characterized by intensified and diversified production of supra‐regional ceramic types.  相似文献

The Cape Stoba shipwreck is located on the seabed off the island of Mljet in Croatia at a depth of 21–28 m. Following initial investigation in 1975, four seasons of excavation have been carried between 2010 and 2014 by the Department for Underwater Archaeology of the Croatian Conservation Institute, joined by the Department of Studi Umanistici of the Università Ca' Foscari of Venice from 2012. The wreck‐site is evidenced by a cargo of nine amphora types dated to the 10th‐11th century AD, produced in the Eastern Mediterranean and Black Sea area, and glassware of Levantine production. The only direct evidence of the ship itself to date, is one iron anchor.  相似文献

The wrecking of the Falmouth Postal Packet Hanover in 1763 led to three legal disputes and two court cases—in 1766 and 1997. This article recounts the origins and course of these disputes. It examines what the resolution of the 18th‐century case and the second dispute has revealed of the law and practice of marine insurance in the mid 18th century. It further examines what the 20th‐century case has revealed concerning the tension between ancient principles of commercial salvage and modern principles of heritage protection. Somewhat fortuitously, the examination of the case provides an opportunity to advance a simple solution to this conflict.  相似文献

This paper provides new data on an under‐documented topic in Aegean archaeology, that of the impact of Latin–Greek cohabitation on craftsmanship, socio‐economic organization and household pottery traditions. The chosen approach is a petrographic study of the provenance and technology of 37 cooking pots, jugs, basins and storage jars from the city of Thebes, Boeotia. The ceramics span from the late 12th to the mid‐14th century and thereby cover the periods of Byzantine, Frankish and Catalan control over the city. The analysis indicates that most pottery products were not locally made during these periods. Pottery consumption at Thebes involved, in the 12th/13th century, regional products from northern Boeotia, while pottery supplies from Euboea that had developed under Byzantine rule continued into the 14th century, well after Boeotia and Euboea came into the hands of, respectively, Frankish and Venetian lords in the aftermath of the Fourth Crusade (1204). The petrographic analysis also allows for the characterization of Byzantine and Latin tempering practices of the pottery fabrics. These results highlight phenomena of regional economic reliance in central Greece and provide rare evidence for the cross‐cultural diffusion of technological knowledge in the late medieval Mediterranean.  相似文献

Deep ploughing near Kilclief, County Down, near the site of an early monastery, disturbed a large quantity of buried stones. One of these displayed a Viking‐type ship with a furled sail. Decorative artwork on the stone suggests an 11th‐century date. The ship displays close similarities to Viking ship graffiti in Viking Dublin and in the Scandinavian homelands. This article describes the decorated stone and suggests that it represents an Irish ship constructed in the Viking style. Documentary sources indicate that ships were being granted by an Irish over‐king to a local king of this area at this time.  相似文献

Achill yawls, originally introduced to Ireland as ships' boats aboard Norwegian merchantmen, developed into distinct working vessels along Achill Island's shores during the 19th century. These boats were subsequently modified for recreational racing in the mid‐20th century. Despite changes to their design, they are often nostalgically viewed as traditional symbols of an Achill islander identity, though their popularity may have been prompted by late‐19th‐century British legislation. The authors take an ethnographic approach in interpreting Achill yawls over time, contextualizing their social functions through an exploration of primary historical and photographic archives, extant vessels, and interviews with Achill islanders. © 2010 The Authors  相似文献

Quantitative calculations on the use of natural resources provide valuable tools, which can give new insights to old questions and rise new ones. In this article, I compare the wood consumption in the production of potash, saltpeter and pine wood tar in 19th century Finland. My calculations shows that in the 19th century the cumulative wood consumption in the production of potash might have been higher or at least on the same level as in the production of tar, while the production of saltpeter consumed only a fraction. In the 1830s their combined wood consumption reached the level of slash‐and‐burn cultivation.  相似文献

Rural settlements growing crops and rearing animals are known as estancias in several South American countries. They played a prevailing role in the political and economic history of Argentina, particularly during the second half of the 19th century and the beginning of the 20th century. At present, many estancias are developing alternative activities, as recreation and tourism, in order to be able to subsist. The main problem lies in the fact that a non‐sustainable activity, frequently focused on the greatest economic yield, leads to the destruction of the heritage, instead of achieving its long‐term conservation. The purpose of this paper is to develop and verify a suitable model for the planning, execution and management of recreational and tourist activities in these rural settlements. As regards the scope of the concept of sustainable development, this methodology aims at achieving a balance between the recreational and tourist operation and the conservation of the rich heritage concerned.  相似文献

An understanding of the nature and magnitude of hydrological, physical habitat and physico‐chemical effects resulting from surface‐water diversions in river systems is essential for effective management of water resources. For most coastal‐draining rivers in New South Wales, however, there are few data available on irrigation diversions, their hydrological impacts and environmental effects. This paper therefore presents an analysis of mean daily surface‐water diversions for pasture irrigation from approximately three years of metered data and the resultant effects on daily flows and aquatic habitats in the Bega‐Bemboka River. The period of analysis of the hydrological effects of irrigation diversions is extended to the full length of record (approximately five years) for gauging stations most affected by irrigation diversions, using Maintenance of Variance Extension Type 1 (MOVE.1) modelling techniques. The annual mean, median and peak daily rates of water diversion by metered surface‐water licences used to irrigate 925 ha of dairy pasture are 10.5 Ml d?1, 7.3 Ml d?1 and 41.5 Ml d?1, respectively. Diversion effects on flow duration statistics are such that the measured 90th and 95th daily flow duration percentiles at the gauging station most affected by upstream irrigation diversions are equivalent to the 97th and 99th flow duration percentiles, respectively, under MOVE.1 modelled natural flow conditions. While diversions for irrigation over the three‐year data period account for only 6.6% of total flow volumes, diversions as a proportion of daily surface‐water inflows increase exponentially under decreasing flow rates. Median and maximum daily diversion rates attain 91% and 118%, respectively, of total surface‐water inflows to the diversion‐affected reach when upstream inflows range from 15 to 20 Ml d?1. This exponentially‐increasing relationship between daily diversion rates and declining surface‐water inflows suggests that ‘rule of thumb’ guidelines on sustainable diversion limits based on mean or median annual percentage diversion volumes need to be applied cautiously to river systems with no or limited capacity to manipulate flows to meet downstream consumptive demands.  相似文献

The cargo of marble blocks off Capo Bianco was dated to the Roman period. New sampling and analysis has identified Carrara marble, and also Rosso di Francia and Portargento, which strongly suggests a post‐medieval date. This leads to the suggestion that nearby finds dating between the second half of the 18th century and the first half of the 19th may come from the same ship, perhaps sailing from France and Liguria to deliver stone in southern Italy. This is rare evidence of the post‐medieval marble trade and demonstrates the importance of archaeometric analysis for the interpretation of wrecked cargos. © 2011 The Authors  相似文献

A project is described concerning the examination of wood from two settlements on Eysturoy. Argisbrekka is a seasonally occupied inland settlement radiocarbon‐dated to the 9th–11th centuries, while Toftanes is a year‐round coastal settlement from the 9th–10th centuries. Preliminary investigations of wood from houses and refuse layers at Argisbrekka demonstrate the utilization of three resources: (a) local vegetation of Juniperus, tree Betula and heathland dwarf shrubs, (b) driftwood Picea and Larix, (c) imported wood Pinus and Quercus. The impact of man and husbandry on the vegetation probably resulted in the extinction of tree Betula and the almost total disappearance of Juniperus.  相似文献

The painted fragments collected during the archaeological excavation campaign in the San Giovanni Battista church in Cevio represent a unique patrimony of Romanesque wall painting in Tessin, Switzerland, having a strong stylistic linkage with the Lombardic art of the same period. The archaeological and stylistic research allowed the fragments to be dated between the 11th and 13th centuries ad and to group them in three chronological phases. The scientific research (p‐XRF, OM, SEM–EDS, FTIR and XRD) was aimed at characterizing the pigments and the pictorial techniques used. Important changes occurred in terms of some pigments used during the 11th and 12th centuries: in particular, azurite was used to decorate the earlier wall paintings while lapis lazuli was used for the 12th‐century ones. During the second period, lead‐based pigments (lead white and minium) were introduced into the palette. The use of natural yellow and red ochres and green earth was common for the three periods. The fresco technique was generally used, except for the application of azurite and lead‐based pigments, where the a secco technique was adopted. The integrated research is a contribution to the knowledge of Romanesque art in the Insubric Region.  相似文献

A set of 33 fragments of lustre‐decorated ceramics uncovered during an archaeological excavation in Manises (Valencia, Spain) have been studied. These ceramics were produced in Manises from the 14th to the 18th century. This well‐dated set of ceramic shards represents the diversity of Manises lustre production and is a complete time sequence of reference for the technological analysis. Texture analysis of the glazes has been carried out by SEM–EDAX, the inner and outer surfaces of the lustre decorations being analysed with non‐destructive ion beams by PIXE and RBS, and also by high‐resolution electron microscopy. The results are compared with other lustre productions and the time trend of the microstructures, glaze and lustre composition is analysed. It is concluded that Sn was used to opacify glazes until the beginning of the 17th century and that changes in the lustre microstructure occurred around ad 1500.  相似文献

The political life of Sir Watkin Williams Wynn, 4th baronet has traditionally been seen in line with Sir Lewis Namier's views of 18th‐century politics and this article seeks to reinterpret his political life, taking into consideration not only his activities within parliament, but also his role within local government and his cultural activities. It will particularly consider the importance of his role within the concerts for ancient music, his lord lieutenancy of Merioneth and the central part he played in the 1778 treasury warrant crisis as well as his vigorous attempts to defend his interest during the 1774 Montgomeryshire election. This article will also argue that the cultural activities of back‐bench country gentlemen within the 18th‐century house of commons can shed new light upon their political views and activities.  相似文献
