Anselm Kiefer: a study of his artistic materials

The style of the contemporary German artist Anselm Kiefer is highly innovative and unconventional and is characterized by the use of diverse materials that he selects and combines according to the emotions that they stir in him. The conservation and preservation of works by Kiefer are particularly difficult tasks because of the heterogeneity and, in some cases, the incompatibility of the materials used; therefore, a thorough characterization is crucial before any intervention is considered. In this paper, we report the results of an investigation on a fragment from a multimaterial work and on samples from the paintings Bohemia Lies by the Sea and Die Größe Fracht. The large fragment was cut by the artist himself from a work in progress and is considered destitute of any artistic value; therefore, it was possible to sample it extensively. This fragment and the samples from the Die Größe Fracht and Bohemia Lies by the Sea paintings were analyzed by ultraviolet (UV) fluorescence imaging, fiber optic reflectance spectroscopy, Fourier transform infrared spectroscopy, nuclear magnetic resonance, Raman spectroscopy, X-ray diffraction, gas chromatography-mass spectrometry, and pyrolysis gas chromatography-mass spectrometry. This multitechnique approach allowed us to fully characterize and identify pigments, dyes, and organic components that reflect the diversity of the materials typically chosen by the artist. The results are evaluated in the context of the interview that Antonio Rava had with the Anselm Kiefer in 2000.     

The Smiling Abbot: Rediscovering a Unique Medieval Effigial Slab

The article reports on a newly re-discovered fragment of a recumbent effigial slab commemorating Abbot Hywel (‘Howel’), most likely an abbot of the Cistercian house of Valle Crucis, near Llangollen (Denbighs.). The slab was probably carved very early in the fourteenth century, and could have covered the abbot’s burial place. The stone was dislocated and fragmented at an unknown point in the abbey’s history, and most likely removed from the site during the nineteenth-century clearance of the abbey ruins. It was briefly reported on in 1895 and has been lost to scholarship subsequently.

If indeed from Valle Crucis, the stone is the only known effigial slab commemorating a Cistercian abbot from Wales, and a rare example from Britain. Given that few similar Cistercian abbatial monuments have been identified from elsewhere, the ‘Smiling Abbot’, although only a fragment, is a significant addition to the known corpus of later medieval mortuary monuments. The article discusses the provenance, dating, identification and significance of the monument, including the abbot’s distinctive smile. The stone sheds new light on mortuary and commemorative practice at Valle Crucis Abbey in the early fourteenth century.     

Le Médium Technique: Objet et <Emphasis Type="Italic">A Priori</Emphasis>

In his fragment on music, Max Weber reduces the empirically describable musical object to the «technical medium» utilized by each culture on condition that its analysis remains heterogeneous in the face of aesthetic valorisations. Weber emphasises that the phonographic reproduction of sound constitutes the condition of possibility of an empirical analysis of the musical material, the point of departure of a modern comparative musicology. The empirical approach and cultural comparison thus appear linked in an «empirico-transcendental» crossover which makes both an object and an a priori out of the technical medium. The article explains this methodological choice and its consequences for a comparative sociology of art.     

FTIR imaging and HPLC reveal ancient painting and dyeing techniques of molluskan purple

Fourier transform infrared spectroscopy and imaging coupled to optical microscopy, scanning electron microscopy coupled to energy dispersive x-ray spectroscopy and high-performance liquid chromatography (HPLC) coupled to diode-array detection are used to investigate two samples removed from a painted decoration of a burial kline and a textile fragment, both found in Koru tumulus (fifth century BCE) in Daskyleion. Tyrian purple and kaolinite were identified in both samples, thus suggesting that the aluminosilicate compound had an important role in the applied painting and dyeing processes. The textile fragment is composed of undyed cotton and silk yarns dyed with the molluskan dye. The relative compositions of the molluskan materials used in the two archaeological objects are similar and comparable with the corresponding composition measured for a purple sample originated from Murex trunculus mollusks according to the HPLC results. This result is supported by principal component analysis (PCA) which, furthermore, takes into account the relative compositions of the extracts of the three Mediterranean mollusks, published in previous reports.     

The Vindolanda Timepiece: Time and Calendar Reckoning in Roman Britain

In 2008 a fragment of a time‐reckoning device was found at Vindolanda. This fragment has been interpreted as part of an anaphoric water clock. There are important differences between this fragment and other objects thought to come from anaphoric water clocks. This article seeks to reinterpret the fragment in terms of a broader array of Roman time‐reckoning tools than anaphoric water clocks and also in terms of the archaeological context of Vindolanda in which the fragment was found. The emphasis on cultural context in interpreting this fragment reveals much about the temporal consciousness of its possible users and maker.     

Evidence of a healed compression fracture in a Plio-Pleistocene hominid talus from Sterkfontein,South Africa

The object of this communication is to draw attention to the appearance of this fossil talus Stw 363, which carries a densely adherent fragment on its posterosuperior aspect. We have endeavoured to verify that this bony fragment could be the posterior half of the fractured calcaneus resulting from a fall on to the animal's left foot. Furthermore, it is suggested that this animal survived long enough for this fracture to unite by bone to the posterior aspect of the talus in this grossly displaced and unreduced deformity.

Abstract

In 1925 a key piece of evidence, a fragment of Sheshonq I's victory stela, was discovered at Megiddo during the preparations for the excavations of the Oriental Institute of the University of Chicago. Unfortunately it was found on the surface, on one of the spoil heaps of the previous German excavations. The Chicago team tentatively assigned the fragment to the lowest level reached in the area, initially called Stratum IV, but said little more about it. In recent years, fresh information concerning both the location and the circumstances of the discovery has been published, which, in the author's view, makes it possible to locate the context in which the stela fragment was found, both horizontally and vertically. It is now clear that the lowest level reached in the area was Stratum V, and the author suggests below that the fragment was reused in Stratum VA, the stela having originally been set up in Stratum V B, dated to the 9th century BC by the current excavators.     

木雕文物的褐腐菌害

为对一尊唐代木雕佛像严重朽蚀的原因进行调查,用扫描电镜观察,对样品的综纤维素、木质素含量等进行分析测定,并对菌进行培养。实验结果表明,木材纤维中有菌丝,真菌孢子,经一定温湿度培养后,腐朽木材上的孢子有发展,说明该真菌在原介质上存活,在合适的环境条件下,将会继续起菌害作用。分析数据说明,综纤维素含量大大降低,木质素的相对百分比含量大大升高,这是综纤维素及其相伴生的戊聚糖受真菌破坏分解的结果。此等菌害的表现应该是属褐腐菌对木材破坏的结果。由于褐腐菌对木材短时间内就能产生强大的破坏力,因此,对木质物的保护要特别重视褐腐菌的侵害。     

Sequential Incisions on a Cave Bear Bone from the Middle Paleolithic of Pešturina Cave,Serbia

We present the detailed analysis of a cervical vertebra from a cave bear, found at Pe?turina cave, Serbia, in a Mousterian archaeological level dated by radiocarbon at 43.5–44.6 kyr cal BP, and by ESR to between 93.5 and 102.5 kyr BP. Identified as a portion of the cranial articular facet, the fragment displays ten subparallel grooves. The microscopic study of these grooves and other surface modification present on the bone fragment, conducted with multifocus optical and confocal microscopes and complemented by a taphonomic analysis of the associated faunal assemblage, supports the hypothesis that the incisions were made by humans. Results are used to critically examine ambiguities implicit in the analysis and interpretation of early engravings, a category of material culture that has been playing a key role in the identification of early instances of symbolically mediated behavior.     

A Cut‐marked and Fractured Mesolithic Human Bone from Kent's Cavern,Devon, UK

An isolated adult human ulna fragment recovered from the ‘black mould’ layer of Kent's Cavern by William Pengelly in 1866 exhibits a series of stone tool cut marks. The specimen has been directly AMS ¹⁴C‐dated to 7314–7075 cal bc (OxA‐20588: 8185 ± 38 bp ) and may be from the same individual as a maxilla fragment dated to the same period. The cut marks are located on the olecranon process, in a position indicative of dismemberment, whereas the fracture characteristics of the bone furthermore suggest peri‐mortem breakage, typical of butchery for the extraction of marrow. We here present and discuss the specimen and consider both ritual mortuary treatment and anthropophagy as possible explanations. Although it is difficult to interpret a single element in isolation, the latter scenario seems to be better supported and is not without parallel in prehistoric Europe, as indicated by a review of the available literature.

Plant microfossils in human dental calculus from Nemrik 9, a Pre-Pottery Neolithic site in Northern Iraq

Samples of dental calculus were taken from 11 human individuals buried at Nemrik 9, a Pre-Pottery Neolithic site in Northern Iraq. All of them represented the time span of ca. 9100–8600 bp. In total, 95 microfossils were retrieved from these samples, including 70 phytoliths, 9 starch granules or clusters of starch, 3 pollens, and 1 xylem fragment. Most microfossils could be attributed to C₃ cool season cereals, most likely wheat and barley, which is consistent with previous knowledge about the composition of crops in early farming communities living in the Fertile Crescent. In addition, three phytoliths and one starch granule typical of C₄ warm season grasses were recovered including one subangular and faceted starch granule, which might derive from a native grass, but is not diagnostic of any genus. Prior to assigning diagnostic status to this starch, exhaustive reference work on native grass seeds is necessary. The presence of one Phragmites phytolith suggests non-alimentary processing of reeds using teeth or perhaps using the stem of this grass as a toothbrush or toothpick.     

A ‘new’ palaeolithic dog from central Europe

Kesslerloch Cave in Switzerland is one of the major Magdalenian sites in Central Europe. During a recent reanalysis of the faunal remains, we identified a cranial fragment and teeth of the domestic dog. The large maxillar fragment was directly dated to 12.225±45 bp (KIA‐33350) or c. 14.100‐14.600 BP. The finds are metrically well below the natural variability of wolves from both Palaeolithic and recent times and even show slight morphological differences to the wild wolves from the site. We argue that the maxilla fragment must now be considered the earliest indisputable directly dated evidence of a domestic dog. Copyright © 2010 John Wiley & Sons, Ltd.     

A Healed Wound Caused by a Flint Arrowhead in a Neolithic Human Innominate from the Trou Rosette (Furfooz,Belgium)

A new case is described here of a wound caused by a flint arrowhead in the neolithic period. The specimen comes from a collective burial excavated last century in the cave Trou Rosette (Belgium). It consists of a fragment of left adult ilium. The fragment of arrowhead is located in a rounded cavity which is open in the medial surface of the bone. The CT scan and the artefact study allow us to reconstruct the scenario of the accident. The arrow pierced the musculus gluteus of the individual prior fixing in the iliac blade. The arrow tip broke at the moment of impact; its tang broke either at the moment of impact or during attempts to extract the arrow.     

Non-destructive Phase Analysis of Archaeological Ceramics using TOF Neutron Diffraction

Mineral phase analysis of ancient ceramics carried out by neutron diffraction yields complementary information to X-ray diffraction analysis. Since neutrons are highly penetrating, neutron diffraction in general allows non-destructive investigations of bulk samples rather than of surface layers or powdered material. This means complete, intact specimens can be studied. A time-of-flight (TOF) neutron diffractometer offers additional advantages considering experimental set-up, accommodation of large objects and data collection times. First test measurements with respect to archaeometric applications have been performed on different fragments of medieval Rhenish pottery using the TOF neutron diffractometer ROTAX at the spallation source ISIS, U.K. Phase fractions obtained from a Rhenish stoneware jar fragment compare well with those from a powder sample prepared from the same fragment. This finding indicates that reliable results can be obtained by illuminating a large piece or even a complete ceramic object without causing damage.     

The impact of the Roman Empire on animal husbandry practices: study of the changes in cattle morphology in the north-east of the Iberian Peninsula through osteometric and ancient DNA analyses

The change in cattle size during the late Iron Age and the Early Roman period is a widely known phenomenon. However, hardly any information is available about this change and its causes in the north-east of the Iberian Peninsula. In order to shed more light on this issue, variations of cattle size and shape through the analysis of Bos taurus remains from ten archaeological sites located in the north-east Iberia and occupied from the middle fifth century bc to the third century ad are examined in this paper. Osteometric postcranial and teeth analyses show a clear change in cattle size and shape during the Romanization period at newly founded sites. This change is documented at all the sites from the Early Roman period. Genetically, authenticated results from a short fragment of the mitochondrial d-loop were obtained from 6 cattle metacarpals out of 33 tested. They affiliate to the main European taurine haplogroup T/T3. The integration of the available data including the archaeological background suggests that the presence of these morphologically different cattle, introduced during the Romanization period, was more pronounced at sites interpreted as villas and trading posts, rather than at cities during the Early Roman period.     

A Rich Bell Beaker Burial from Wellington Quarry, Marden, Herefordshire

An intact Bell Beaker grave was discovered in February 1996 at Wellington Quarry, Marden, Herefordshire. The unmarked flat grave had no signs of a ditch or barrow, but may have been timber lined. It contained a tanged copper knife, a shale wristguard fragment, four barbed and tanged arrowheads, three arrowhead blanks, three flint knives, two triangular points or small daggers and four flint flakes. The adult male inhumation was accompanied by a complete, Maritime (AOO) Bell Beaker and may be dated to 2750–2500 BC (Late Neolithic). It belongs to Case's Group D. A notable feature of the grave goods is their different states of wear and completeness, varying from pristine to old, and including a fragment of a wristguard.
