THE PUZZLE OF THE BANQUET HALL OF THE DUKES: THE PROFESSIONALIZATION OF SWEDISH HISTORICAL RESEARCH STUDIED THROUGH LUDWIK FLECK'S “THOUGHT COLLECTIVE” AND “THOUGHT STYLE”

In 1312, the Swedish dukes Erik and Valdemar Magnusson married the Norwegian princesses Ingeborg Haakonsdaughter and Ingeborg Eriksdaughter at a ceremony in Oslo, Norway. In 1313, the two couples were reunited at a purpose-built banquet hall, believed to have been located in the medieval Swedish town of Lödöse. The main source of information concerning these events is the Swedish medieval rhyme chronicle The Chronicle of Duke Erik. However, a closer reading of the chronicle reveals that Lödöse is never mentioned in relation to the banquet hall. The article discusses the passing down of knowledge through generations of the same professional collective, in this case the professional collective of Swedish historians during the twentieth century, and demonstrates how the validity of once-established prescientific knowledge persists. To achieve its goal, the article applies Ludwik Fleck's terms “thought collective,” “thought style,” and “tenacity in science,” as well as Thomas Kuhn's concept of the “paradigm,” to a historiographical case study of how the proto-idea of the banquet hall being located at Lödöse has survived to become an established scientific fact. The location of the banquet hall concerns but a minor detail in the turbulent political situation of the Swedish kingdom during the first decades of the fourteenth century. However, the continuing reiteration of this minor detail is evidence of a larger phenomenon, namely how contemporary historical research is influenced by scholars in the prescientific past.     

Characterizations of palace lantern tassels preserved in The Palace Museum,Beijing, by UPLC-ESI-Q-TOF

Palace lanterns were important and highly visible decorations in the imperial palace in Beijing, China, during the Qing dynasty (1636–1912). Most lanterns had colourful tassels made of fibres. The study performed a comprehensive investigation of the materials and dyes used for palace lantern tassels preserved in The Palace Museum, Beijing. Eight samples with different colours, including yellow, green and red, from five palace lanterns were analysed. By using ultra-performance liquid chromatography combined with time-of-flight mass spectrometry, the compositions of the dyes were identified quickly, and thus the dyes' origins were explored. A X-ray fluorescence spectrometer assisted in the detection of whether a mordant was used during the dyeing process. As a result, the tassels were all made of silk, discovered through the use of microscopic observation and micro-Fourier transform infrared spectrometry analysis. Different dyeing techniques were found in these tassels: yellow tassels were dyed by cork tree or turmeric by a direct dyeing method; greens were dyed by pagoda bud with an iron mordant, or by the combination of cork tree and indigo using multi-dyeing method; and red tassels were coloured with different acid red industrial dyes. These results provide valuable data for the conservation of ancient textile tassels and contribute to the investigation of other hanging tags.     

Neutron activation analysis of fine grey pottery from Conimbriga,Santa Olaia and Tavarede,Portugal

The concentrations of two major elements and thirteen trace elements in 73 selected sherds of fine grey ware from the Iron Age and Roman period, excavated at Conimbriga, Santa Olaia and Tavarede, Portugal, were determined by instrumental neutron activation analysis. These concentrations were used to calculate distance matrices which were then subjected to cluster analysis employing SAHN and k-means methods, as well as to principal components analysis, to group the sherds according to the overall similarity of their compositional characteristics. The results showed that equivalent groupings appeared regardless of the taxonomic method used. Two major clusters were recognized corresponding to two different sites, namely Conimbriga and Santa Olaia, suggesting that the ceramics from these sites were made locally. No significant differences in compositional patterns were observed between iron age and roman sherds from Conimbriga.     

A first fossil record for Scolytus scolytus (F.) (elm bark beetle): its occurrence in elm decline deposits from London and the implications for neolithic elm disease

A problem which has arisen in discussions of an elm-disease explanation for the Neolithic elm decline has been the lack of fossil records of Scolytus scolytus (F.) (elm bark beetle), which is the main carrier of the fungus which causes the present epidemic of Dutch Elm Disease. Now, the discovery of wing cases of two individuals from elm decline deposits at Hampstead Heath, London, proves that the beetle was present in Britain during this episode. The deposits in which it occurs are described, and the various implications for elm disease causing, aiding or at least occurring during this stage of the early Neolithic are discussed.     

“Die wissenschaftliche Ausbildung des Arztes ist eine Culturfrage …”. Über das Verhältnis von Wissenschaftsanspruch,Bildungsprogramm und Praxis der Medizin

The article shows that the elite, nationalistic and imperial mentality of German medicine in the second half of the nineteenth century was closely connected to its aim to be understodd as a natural science. With this in view leading representatives of German medicine propagated a scientific approach to man and nature instead of the traditional values of humanistic education (“Bildung”). One of the most important consequences of the new scientific ideal in medicine — integration in governmental planning, the change in professionel status of doctors, the increasing tendeny to recognize biologistic ideologies — was the loss of the medical ideal of the ars medica, a subject which has not received sufficient thematic attention. This theme is explored in the third part of the article.     

Neutron activation analysis of stone from the Chadron Formation and a Clovis Site on the Great Plains

Cryptocrystalline silicates from the Chadron Formation were widely used by prehistoric human groups in the Great Plains of North America. There are two documented quarry areas: Flattop Butte in Colorado and the White River Badlands of South Dakota. Cryptocrystalline silicates from these sources are visually indistinguishable, making it difficult to determine the sources of artefacts found at archaeological sites. In this investigation, neutron activation analysis is used to distinguish the two sources. This technique also identifies lithic material from the Clovis-age Eckles site in Kansas as being from Flattop Butte.     

Zoologische Gärten in Stadtkultur und Wissenschaft im 19. Jahrhundert

The foundation and administration of European Zoological gardens in the 19^th century is analized. It is significant of such new institutions, that they are founded in the large cities, and that most of the founders looked at the great models in Paris and London, which are described first. Further it is shown that the change from princely menageries to public Zoological Gardens is caused both by common interests in people's education and pleasure and by scientific aims which leaded to choose the name Zoological “garden” in analogy to botanical gardens. It seems to be characteristic of such public institutions created by citizens in the 19^th century that they are mostly supported by commercial or scientific local societies. This is exemplified by describing the administration of the Zoological gardens of Berlin (1841), Frankfurt (1856) and Hamburg (1863), which initiated also research for acclimatization of wild animals.     

Britische Politiker als Liebhaber der Wissenschaft (ca. 1850–1914) — Zur Ideologie des Amateurismus

The various scholarly and scientific endeavours — comprising both arts and sciences —, which British statesmen persued in their leisure time, transcend the mere biographical aspect. In the light of the slow, yet steady professionalisation of educational and political institutions, many of them modernised or newly created in order to achieve what came to be called “National Efficiency”, the literary and scientific pastimes of men, like Gladstone, Morley, Salisbury, Balfour or Haldane, seemed soon to become somewhat obsolete. Yet, it is argued, that the often professedly amateurish activities did not merely display the traditional hobby attitude to the sciences, so characteristic of the wealthy aristocrat, but in some cases revealed a good understanding of the scientific and educational needs of society, leading up to their active advancement. The British amateurs, it would seem, were pleading for providing a balanced higher education and training, rather than going for the technical excellence of the political rival Imperial Germany, which dazzled and, at the same time, intimidated some of them.
