Viking woollen square-sails and fabric cover factor

The discovery of the five scuttled Viking ships of Roskilde Fjord in Denmark and the subsequent excavation, preservation and analysis of the remains has initiated a programme of reconstructive archaeology led by the Viking Ship Museum of Roskilde in which four of the five hulls have now been reconstructed together with their rigs and square-sails. The reconstruction of the sails has been based on fragments of heavy woollen cloth found within the roof of Trondenes church in Norway dating to the mid-13th century. This paper uses the'cover-factor' modelling methods of modern textile engineering to analyse the'Viking' sail fabrics and assess their strength, resilience and performance in comparison with the linen sails from the wreck of the Vasa .     

Bahamian Ship Graffiti

In the Age of Sail the Bahamas was on major routes between the Americas and Europe. Bahamians developed a way of life using their location to advantage. Ship graffiti are the first archaeological evidence of Bahamian shipping activity. The graffiti are unique in the region, being incised into a variety of stone surfaces, and probably other surfaces which have not survived. Images depict locally-built vessels such as sloops and schooners as well as larger, ocean-going ships. Graffiti locations are predominantly associated with people of African heritage and lower socio-economic status. Details suggest artists were familiar with ship construction and rigging.

Sailing the Pepper Wreck: a Proposed Methodology for Understanding an Early 17th-Century Portuguese Indiaman

Discovered in 1993 at the mouth of the Tagus River, the SJB2 shipwreck—or ‘Pepper Wreck’—was tentatively identified as the Portuguese Indiaman Nossa Senhora dos Mártires, lost on its return voyage from Cochin, India, on 14 September 1606. Following archaeological excavation and a tentative reconstruction of the ship's hull and rigging, the next step is the study of its structural strength and sailing characteristics using the tools of modern naval architecture. This paper presents a methodology for investigating the sailing and structural characteristics of the ‘Pepper Wreck’, combining archaeological, iconographic and contemporary written sources with modern naval architectural calculations. © 2005 The Authors     

Sails from the Roman port at Berenike, Egypt

A 1st-century AD midden deposit at Berenike, a major port on the trade route between the Roman Empire and India, has produced cotton textile fragments reinforced with a rectangular grid-pattern of cotton strips, interpreted as the remains of sails. Webbing fragments of cotton and linen, in some cases attached to stout cotton or linen cloth, may also have come from sails. The only published example of a Roman-Period sail is a linen sail of 1st-century BC-AD date from Thebes in Egypt, to which the Berenike fragments bear a close resemblance. The S-spun linen sails were presumably manufactured in Egypt. Most of the Berenike material, however, was of Z-spun cotton: an import, it is argued, of Indian origin. The construction of Mediterranean-type sails entirely from Indian materials has implications for the presence of Westerners on the Indian sub-continent.     

To be or not to be a cog: the Bremen Cog in perspective

Following on from Thijs Maarleveld's paper in 1995 on type-names for archaeological finds of ships, the use of the term cog has been questioned by Timm Weski, who suggested the archaeological term Ijsselmeer-type instead. The present paper surveys a total of 18 ship-finds of this type with respect to date, origin and year of investigation, without finding support for the proposed change in terminology. Instead, the archaeological term cog should be restricted to seagoing vessels of the 12th–15th centuries which share the structural features of the lower part of hull with the Bremen Cog.
Recent results of dendroanalysis point to the root of the Jutland peninsula as a more likely area than the former Zuiderzee for the transformation of a hypothetical older'proto-cog'-type for navigation on rivers and in the Waddensee into the proper seagoing medieval cog-type. Impulses for this transformation were found, most likely, in the need to circumnavigate Cape Skagen already in the 12th century, and technical features were probably taken over from large Scandinavian cargo ships of that period. © 2000 The Nautical Archaeology Society     

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     

Bai Jiao 1—the excavation of a Song Dynasty shipwreck in the Dinghai area, Fujian Province, China, 1995

The ships that sail the Southern Sea and south of it are like houses. When their sails are spread they are like great clouds in the sky… The big ship with its heavy cargo has naught to fear of the great waves, but in shallow water it comes to grief (cited in Guy, 1992: 18).     

Trace element and Pb isotope provenance analyses of native copper in northwestern North America: results of a recent pilot study using INAA,ICP-MS,and LA-MC-ICP-MS

Several indigenous groups in northwestern North America used native copper prior to EuroAmerican contact. The Arctic, Subarctic, and Northwest Coast culture areas all have archaeological finds and geological sources of native copper. The copper-rich region of south-central Alaska and southwestern Yukon has often been credited as the source of archaeological native copper found on the Northwest Coast despite the presence of native copper sources further south. This paper presents the results of a pilot study using INAA, ICP-MS, and LA-MC-ICP-MS to assess the potential for native copper provenance research in Alaska and the Yukon Territory. Discrete native copper sources could be distinguished from one another intra-regionally. Difficulties associated with future native copper provenance research in northwestern North America are discussed.     

Managing for Effective Archaeological Conservation: The Example of Salisbury Plain Military Training Area,England

Abstract

Salisbury Plain Military Training Area, Wiltshire, England is the major zone of southern Engizsh chalk downland where archaeological field monuments are comparatively well preserved over large areas. The land is currently managed with regard to military considerations, to its secondary use for forming, and to conservation concerns. Following expressions of concern about archaeological damage, a working party was set up to evaluate the present state of archaeological survival and to recommend for the future. A survey of all sites evaluated their condition by means of a scoring system. Recommendations were made about military use, agriculture, and controlling natural agencies of destruction; and a solution was offered that incorporated eight elements of strategy. The Salisbury Plain study is considered in its context—the English national policy that there should be an archaeological stock-taking of what we have, and a scoring system to make possible some rational choice in selecting from it what is most precious and what is in most need of protection.     

Probing the provenance of archaeological glaze colorants: Polychrome faunal reliefs of the Ishtar Gate and the Processional Way of Babylon

The polychrome glazes from the Processional Way and the Ishtar Gate of Babylon are among the best preserved from antiquity. Yet, little is known about the logistical choices involved in their production. Variations in isotope ratios can be useful for complementing an archaeological investigation of potential geological sources of raw materials. Consistent with archaeological evidence and ancient texts on trade in metals, Turkish ore deposits are thus tentatively proposed as possible sources of the metal oxide colorants used for the investigated polychrome glazes of three Neo‐Babylonian faunal reliefs that are now part of the collection of the Ny Carlsberg Glyptotek, Copenhagen.     

Sailing and Sailing Rigs in the Ancient Mediterranean: implications of continuity,variation and change in propulsion technology

Ships and boats form the foundations of the maritime connectivity that is a central part of our understanding of the ancient Mediterranean. While the general chronological sequence of sail and sailing‐rig development is well established, the implications are less‐well discussed. This article sets out how sails and sailing rigs developed in antiquity, with emphasis on the Greco‐Roman world. Subsequently, instances of innovation are defined. Why specific pieces of maritime technology were, or were not, widely adopted is considered. Long‐term technological continuity can be comprehended, and a shared maritime culture of sailing in the ancient Mediterranean is suggested.     

The Mediterranean Lateen Sail in Late Antiquity

The Mediterranean lateen sailing rig has been studied since the early-to-mid-20th century. Recently-published depictions of sailing vessels rigged with lateen and settee sails, dating to the late-antique period, allow some of the principle characteristics of that rig to be established. This allows comparison with lateen- or settee-rigged vessels from both earlier and later periods. The sailing rigs depicted on other vessels can be identified and the level of technical continuity between the late-antique and medieval Mediterranean addressed. Finally it is possible to assess the extent to which the lateen sail was established in the Mediterranean by late antiquity.

Archaeological wells in southern France: Late Neolithic to Roman plant remains from Mas de Vignoles IX (Gard) and their implications for the study of settlement,economy and environment

Abstract

A study of plant remains from seven archaeological wells at Mas de Vignoles IX, near Nîmes, southern France, was used to shed light on a current gap in the archaeological record caused by erosion and modern agriculture. The analysis also explored the reliability of these sources for palaeoenvironmental and palaeoeconomical information. Significant results on the spatial organization of human habitation, economic activities, and on the environment and its exploitation were obtained for the Middle Neolithic to Roman periods. Furthermore, the Neolithic wells also provided the first early finds of fig seeds in France. The abundance of weed and ruderal plants up to the Iron Age is consistent with data from other studies and their dramatic decrease during the Roman period may have resulted from radical changes in land management. The study marks the first time, in southern France, that a group of wells from a single site have provided a complete record throughout the later prehistoric and Roman periods.     

A Case of Foot Amputation from the Wari Imperial Tomb at Castillo de Huarmey,Peru

Evidence of surgical interventions leaving traces on bones is quite abundant in archaeological material all over the world and is found frequently in the Andes. Among them, trepanations are most common, while amputations represent a relatively small part of the material. These have been reported from a few sites on the Peruvian north coast and archaeologically associated with the Moche culture. In 2013, two new cases from this area were found in situ within the Wari imperial mausoleum excavated at Castillo de Huarmey. Two individuals, one man and one woman, were found in the antechamber, serving as guards for the occupants of the main burial chamber. Their left feet were amputated, disarticulated at the ankle joints, a long time before they died. The article presents this find and discusses the form of amputation and the possible reasons why it was performed. As the context of both individuals possessed the same specifics, suggesting that they performed similar tasks related to religion and ritual, this article also presents a cultural interpretation of these finds, using other artefacts—ceremonial beakers in the form of the left human foot—known from Wari and Tiwanaku cultures.

Rats cannot have been intermediate hosts for Yersinia pestis during medieval plague epidemics in Northern Europe

The commonly accepted understanding of modern human plague epidemics has been that plague is a disease of rodents that is transmitted to humans from black rats, with rat fleas as vectors. Historians have assumed that this transmission model is also valid for the Black Death and later medieval plague epidemics in Europe. Here we examine information on the geographical distribution and population density of the black rat (Rattus rattus) in Norway and other Nordic countries in medieval times. The study is based on older zoological literature and on bone samples from archaeological excavations. Only a few of the archaeological finds from medieval harbour towns in Norway contain rat bones. There are no finds of black rats from the many archaeological excavations in rural areas or from the inland town of Hamar. These results show that it is extremely unlikely that rats accounted for the spread of plague to rural areas in Norway. Archaeological evidence from other Nordic countries indicates that rats were uncommon there too, and were therefore unlikely to be responsible for the dissemination of human plague. We hypothesize that the mode of transmission during the historical plague epidemics was from human to human via an insect ectoparasite vector.     

What goes in does not always come out: The impact of the ruminant digestive system of sheep on plant material,and its importance for the interpretation of dung-derived archaeobotanical assemblages

Abstract

On archaeological sites where livestock dung was a major fuel source, plant material that survives digestion intact may well be preserved in the remnants of dung-fuelled fires. Preserved plant remains which were derived from dung relate to the diet of animals, and thus provide a way of investigating the agro-pastoral economies of the past. In order to improve our understanding of the taphonomic processes to which plant material is exposed to during digestion, we applied archaeobotanical methods to the analysis of dung from sheep fed a known diet of cereal and wild plant material. Two clear patterns emerge from these investigations. First, cereal material (grain or chaff) survives digestion poorly and was rarely found in the dung analysed. Second, large proportions of seeds of various wild species survive digestion in an identifiable form, probably due to their small size and/or protective coating. These findings are crucial for reliable interpretation of dung-derived plant material in archaeological settings.     

Graphical Reconstruction and Comparison of Royal Boat Iconography from the Causeway of the Egyptian King Sahure (c.2487–2475 BC)

Recently published reliefs from the causeway of Sahure and a review of contemporary iconography and archaeological data shed new light on a variety of features of Old Kingdom royal sailing boats and equipment, such as quarter rudders, rigging, signalling devices, decorations and crew. Furthermore, another relief depicts men paddling in a sequential or what appears to be a wave pattern. Only one other such relief exists. A comparison of both reveals that they are different boat types. One is a specialized racing boat and the other appears to be a larger boat possibly designed to be rowed.     

A set Archaic anchor arm exposed within P. oceanica matte at Klazomenai/Liman Tepe,Turkey: A contribution for understanding marine stratigraphy

Excavation in Posidonia oceanica matte in the ancient harbor of Klazomenai/Liman Tepe, on the Aegean coast of Turkey, demonstrates the stratigraphic archaeological potential of underwater excavation. Among the finds is a fractured wooden anchor arm exposed in situ. The anchor arm dates to approximately 600 b.c. based on stratigraphically associated ceramics, a dating supported by radiocarbon. The arm was found embedded in this marine sediment, which preserved the arm in its set position within the ancient sea floor. This archaeological excavation through matte and silt harbor sediments overturns the misconception that stratigraphic excavation is impossible in a marine environment. The excavation further boosts optimism regarding the preservation of maritime heritage along the littoral of the eastern Aegean and the many other Mediterranean regions where Posidonia oceanica grows.     

Rigging the Pepper Wreck. Part 2—Sails.

Discovered in 1993 at the mouth of the Tagus River, the SJB2 shipwreck—or Pepper Wreck—was tentatively identified as the Portuguese Indiaman Nossa Senhora dos Mártires , lost there on its return voyage from Cochin, in India, on 15 September 1606. Its archaeological excavation led to a tentative reconstruction of the hull, based in contemporary texts on shipbuilding. Further analysis of these texts allowed us to propose a reconstruction of the rigging.
