MICROSCOPIC IDENTIFICATION AND SOURCING OF ANCIENT EGYPTIAN PLANT FIBRES USING LONGITUDINAL THIN SECTIONING*

Plant fibres and the artefacts constructed from them often remain overlooked in the archaeological record because of their poor survival and the problems related to the precise identification of the species to which the fibres belong. The goal of this study was to design a simple and accurate method of identifying archaeological plant fibre sources. Twenty‐two fibre samples from two sets of ancient Egyptian botanical artefacts were examined under both a stereomicroscope and a compound microscope, and compared to a large reference collection and to previously published research. By examining longitudinal thin sections of the ancient plant specimens, we identified plant fibres from the following species: Hyphaene thebeica, Cyperus papyrus, Desmostachya bipinnata, Imperata cylindrica, Phragmites australis and Linum usitatissimum. Our identification of these plant fibres reveals essential information about the materials used for producing ropes, baskets, sandals, mats and fabric. The results of this study demonstrate the value of longitudinal thin sectioning and light microscopy as a major means of identifying the source material of botanical artefacts, and advance our knowledge of ancient Egyptian plant exploitation as well as the associated technologies involved in constructing these types of artefacts.     

EVALUATION OF THE APPLICABILITY OF CONVENTIONAL METHODS FOR THE CHEMICAL CHARACTERIZATION OF WATERLOGGED ARCHAEOLOGICAL WOOD

A series of 112 waterlogged archaeological wood samples of different provenances, wood species, burial times and states of preservation were analysed with the aim of assessing the validity (in terms of limits and reliability) of procedures conventionally used in the pulp and paper industry, to evaluate the state of preservation of decayed wood. In particular, the extent of any damage wrought on decayed wood tissue by the repetitive cycles that characterize these procedures was evaluated as a function of the degradation of the samples. The results indicated that standard methodologies give reliable measurements regardless of the extent of wood decay. However, it is essential to compare these data with those of non‐decayed wood that has been measured using the same procedures to take account of the errors that are inherent in these methodologies and that affect measurements.     

THE CHARACTERIZATION OF WATERLOGGED ARCHAEOLOGICAL WOOD: THE THREE ROMAN SHIPS FOUND IN NAPLES (ITALY)*

Three apparently well‐preserved shipwrecks dating back to Roman times were brought to light near Piazza Municipio in Naples (Italy), during the excavation for the construction of Line 1 of the subway. The shipwrecks were covered by marine sand and silt, below the water table. In order to establish the nature and the extent of wood degradation and, therefore, determine how best to preserve the shipwrecks, a diagnostic investigation was carried out. The study involved the identification of wood species, chemical characterization of the residue component and physical and micro‐morphological characterization.     

The Use and Deployment of Modern Wood Samples as a Proxy Indicator for Biogeochemical Processes on Archaeological Sites Preserved in situ in a Variety of Environments of Differing Saturation Level

Abstract

In situ preservation of archaeological sites is becoming an ever increasing trend as a means of preserving our cultural heritage. In connection with this the environmental conditions, such as water level, dissolved oxygen, temperature, pH and water chemistry, of a site are often monitored. It is generally agreed that a waterlogged and anoxic environment is essential for optimal preservation conditions but the set-up and maintenance of an environmental monitoring programme can be costly.

This paper discusses the design and use of a system whereby modern samples of wood can, with a minimal disturbance of the soil, easily be deployed and retrieved from archaeological sites. The system was deployed in an unsaturated environment, an environment with fluctuating water levels and a fully saturated peat bog. The samples were assessed after two years using microscopic, physical and molecular biological methods, and the types of wood-degrading organisms seen were compared with the results of environmental measurements. Modern wood samples were used, as the microbial ecology of wood-degrading organisms in these different types of environments is relatively well documented. Preliminary conclusions show that the deterioration processes of modern wood samples in these environments act as a good proxy indicator of the environmental conditions and biogeochemical processes ongoing at a site.

Development of an enzyme‐linked immunosorbent assay based on the monoclonal antibody of Bombyx mori to detect ancient silk

Identifying the traces and residues of unearthed silk fibres is crucial for further analysis and study. In this study, an enzyme‐linked immunosorbent assay (ELISA) based on the monoclonal antibodies specific to Bombyx mori fibroin was developed in order to for detect ancient silk. Five monoclonal antibodies were successfully prepared based on fibroin hydrolysate, and four had a high specificity for mulberry silk. Furthermore, they could be used to discern B. mori fibre from tussah fibre and eri fibre. The ELISA standard curve of the most sensitive monoclonal antibody, anti‐Silk Fibroin (SF)‐3, was y = 0.022x + 0.177 (R² = 0.998), and the detection limit was 4.65 ng/ml. Using this antibody, we successfully identified five ancient mulberry silk samples from different time periods. The results suggest that ELISA assays based on monoclonal antibodies can be used as an immunological testing method for unearthed silk fibre.     

PHYSICO‐CHEMICAL CHARACTERIZATION OF THE ACQUALADRONE ROSTRUM

The archaeological discovery of the Acqualadrone rostrum (an offensive naval weapon mounted on the prow at the waterline), off the Italian coast near Messina in 2008, has led to the need for scientific research in order to plan the conservation treatment of this artefact. The discovery is exceptional because of the presence of a wooden section from the original ship. This paper describes the physico‐chemical characterization of a metallic and two wooden samples by inductively coupled plasma – optical emission spectroscopy, inductively coupled plasma – mass spectrometry, Fourier transform infrared spectroscopy, ¹³C {¹H} cross‐polarization magic angle spinning NMR spectroscopy, energy‐dispersive X‐ray spectroscopy, gas chromatography – mass spectrometry and X‐ray diffraction. The results reveal the use of leaded bronze (Cu, 70%; Pb, 20%; Sn, 10%) in the manufacturing process of the alloy and the use of lead whose isotopic composition is referable to either Spanish or Cypriot mines. The analysis of the results relating to the wooden samples indicates their different state of preservation and, at least in some places, the spreading of caulking on the wood, probably using a vegetable resin.     

Is It Hop? Identifying Hop Fibres in a European Historical Context

Hop (Humulus lupulus L.) is an ancient perennial crop plant, native to the Northern Hemisphere. The archaeological evidence dates back to at least the sixth century ad in Europe. Hop has been used for beer brewing, in sleeping draughts, as bedding and for antibacterial purposes. Less known is that hop fibres have also been used for textiles and paper. However, it is difficult to distinguish hop from other bast fibres. Here, we present a set of fibre features, which, when found together in an archaeological/historical material within a European context, provide a strong indication that the fibres are hop.     

Wood identification of a wooden mask using synchrotron X-ray microtomography

Recently, an old wooden mask was discovered at Yatsushiro city, Kumamoto Prefecture, Japan. This mask has been handed down from the end of the 16th century; a Japanese man of arms brought it from the Korean Peninsula during the war between Japan and Korea. In the Korean Peninsula, Hahoe masks have been stored in the Hahoe village and were designated as national treasures in 1964 and are presently possessed by the National Central Museum. Some concerns existed that this wooden mask could be one of the Hahoe masks. Since the Hahoe masks in Korea have all been made of alders (Alnus spp.), wood identification became a key issue to answer the abovementioned concerns. In fact, a flaked sample fragment was available and it was small and brittle enough to be sectioned without embedding. Furthermore, the sample was compressed in the tangential direction so that the surface was not clear enough to be explored by a scanning electron microscope. In this study therefore, a synchrotron X-ray microtomography at SPring-8 was used for the first time for wood identification. The experimental setup of BL20XU at SPring-8 allowed us to image any wood sample at a special resolution of 0.5 μm, which is enough to explore most anatomical features for wood identification established using optical microscopy. The sample was clearly diffuse-porous hardwood characterized by uniseriate heterogeneous ray and simple perforation. As a result, the mask turned out to be made of Salix sp., and the possibility that it is one of the Hahoe masks was ruled out.     

Son Chint’ae and the Foundations of Modern Korean Folklore Studies

Although there were various antecedents, the academic discipline of folklore did not begin in Korea until the third decade of the twentieth century. The leading figure in the country’s development of the discipline is Son Chint’ae, who brought rigour to the methods of research and the collection of material; used a comparative method drawing on research from anthropology, ethnography, folklore, archaeology, and history; and saw ‘Korea’ in the broader context of North-east Asia. A nationalist during the Japanese colonial period, Son used the concept of minchok (the people) both to analyse his material and to serve as a means to revitalize the Korean nation.     

X‐RAY SUB‐MICRON TOMOGRAPHY AS A TOOL FOR THE STUDY OF ARCHAEOLOGICAL WOOD PRESERVED THROUGH THE CORROSION OF METAL OBJECTS

Wood preserved in the corrosion layer of two early medieval iron objects was examined using X‐ray tomography. A state‐of‐the art multi‐resolution X‐ray tomography set‐up ( http://www.ugct.ugent.be ) provided virtual cross‐sections of the archaeological wood samples at sub‐micron resolution. These were compared with scans of samples of similar modern wood. These scans demonstrate the power of sub‐micron X‐ray tomography for wood identification, although the process of mineralization pushes this technique to its limits. Furthermore, this technique facilitated appraisal of the mineral content of the archaeological wood, which is useful in selecting the most appropriate strategy for the (preventative) conservation of the archaeological object.     

ORGANIC RESOURCES AT THE IRON AGE DÜRRNBERG SALT‐MINE (HALLEIN,AUSTRIA)—LONG‐DISTANCE TRADE OR LOCAL SOURCES?*

Remarkable preservation circumstances for organic material at the Iron Age salt‐mine on the Dürrnberg Mountain offered the opportunity to analyse a large amount of wood and human faeces. One aim of the studies was to discover the origin of the important resources food and wood. Concerning the question of ‘the linking role of the Alps in past cultures’, the archaeobotanical record proves intracultural but no intercultural connections at this place in Celtic times. The preliminary results show that the Dürrnberg population used differentiated strategies to manage a continuous food and wood supply. While the wood supply was based on the management of local sources, the food supply had to be linked into a regional and long‐distance trade system.

Probable Fibres from Hemp (Cannabis sativa L.) in Bronze Age Scotland

Abstract

Diameter measurements of bast fibres from cloth and string with a hoard of bronze age metalwork found in St Andrews, were different from those of flax (Linum usitatissimum L.) but comparable with those of hemp (Cannabis sativa L.) leading to the suggestion that hemp was used as a textile fibre in Britain much earlier than has been thought.     

Multi‐analytical Studies of the Lime Mortars from the Yanxi Hall in the Yangxin Palace of the Palace Museum (Beijing)

For centuries, the architecture of the Palace Museum represented the highest standard of Chinese architecture. The Yangxin Palace of the Palace Museum consisted of 18 masonry buildings built using bricks, wood, roof tiles and various mortars. In 2016, a five‐year project was initiated to work on the maintenance and restoration of the Yangxin Palace buildings. The characterization of the construction materials has become of primary importance, in order to obtain information about the raw ingredients and building technology of the mortars, and the history of possible previous restorations. In this paper, 12 different samples representing three types of mortar‐based materials—namely, jointing mortars between the bricks on the wall, and surface plasters as well as mortars used on the roof—were collected for analysis from the Yanxi Hall of the Yangxin Palace. Analysis into the composition, grain‐size distribution, organic and fibre additives and testing of the mortar density and water absorption were performed. Starch, protein and plant fibres were identified in some of the samples. Brucite, mullite and ettringite were detected within most mortars on the roof, possibly originating from the furnace slag added into the raw materials for restoration purposes. The analytical results will serve as a critical reference for the maintenance and restoration of the buildings in the Yangxin Palace.     

Kusanagi Tsuyoshi x Chonangang: Transcending Japanese/Korean Ethnic Boundaries in Japanese Popular Culture

In the last ten years or so, interest among the Japanese in their Korean neighbour has increased significantly. Yet, before the Korean Wave hit Japan in the early 2000s, Kusanagi Tsuyoshi, member of popular Japanese boy-band SMAP, had already débuted and gained popularity as Chonangang, his Korean alter-self. From releasing a Korean pop-music single to interviewing South Korean Presidents on Japanese national television, it is undeniable that Kusanagi (and Chonangang) has brought Korea closer to the hearts of the Japanese. In this paper, I argue that Kusanagi's performances of and as Chonangang create a polyglotic, hybrid identity that functions as a “third space” through which notions of an underlying, essential Japanese (and Korean) identity can be destabilised. Beyond mere entertainment, Kusanagi's adoption of an identity position that is neither Japanese nor Korean, yet also both Japanese and Korean, enables the articulation of difference and hybridity which, I contend, has direct relevance to Japan–Korea and Japanese–resident Korean relations.     

Ordinary Writing and Scribal Culture in Nineteenth-Century Spain: Memory Books

This article is a study of the survival of scribal culture in nineteenth-century Spain in the form of the so-called ‘memory books’ (libros de memorias). I analyse their relationship with the educational developments of the period, as well as the material characteristics and the content of these texts, in order to define their typical features. These texts were the products of hybrid writing practices, in the sense that several elements were frequently superimposed on one another: economic news, personal, family and social events and even historical details. Hence the similarity between the memory books and other genres such as account books (libros de cuentas) and family books (libros de familia). Lastly, I will examine some nineteenth-century examples as epigones of a writing genre which had its origins in the later Middle Ages and Early Modern period.

“One morning, while tidying up the bedroom, Rosa opened the drawer in the trunk where Cholo kept his papers. There she found the papers about the property and, in a corner, together with the Family Book and the social security booklet, the papers from the bank […]. And she was about to put it away when it occurred to her to take off the elastic band around the big folder which Cholo had kept from his time in Switzerland. There were things, names and so on that she didn’t understand, but in the middle there were also some of the cards she had sent from Aran.”1 1.?Manuel Rivas, En salvaje compañía (1994) (Madrid: Alfaguara, 1998), 100–101.

La ragion di Stato in biblioteca

The Fondazione Luigi Firpo, based in Turin, houses the library collected by Luigi Firpo (1915–1989), one of the most distinguished European historians of early modern political thought. The collection includes around 6 000 16^th, 17^th and 18^th century books, among which one can find almost all European literature on the reason of State. The Foundation organizes international conferences, grants scholarships and publishes the research of young scholars. Therefore it has established itself as one of the leading research centres on political thought and on early modern and modern history.     

Miocene wood from the LaTrobe Valley coal measures,Victoria, Australia

An initial study of a collection of fossil conifer wood is reported from the late early Miocene Yallourn Clays, an interseam unit intergrading into the base of the early to middle Miocene Yallourn seam of the LaTrobe Valley, Victoria in southeastern Australia. The fossil wood shares characteristics with the modem genera Dacrycarpus and Dacrydium. On the basis of contiguous, uniseriate tracheid pitting and 1–2 podocarpoid cross field pits, it is placed in the form genus Podocarpoxylon, and the new species P. latrobensis. The wood is compared with extant Podocarpaceae and other Australian fossil woods. Its ring anatomy is consistent with low temperature or rainfall seasonality in the early Miocene.
