Weld (Reseda luteola) was one of the main sources of yellow dyes used for dyeing textiles and to prepare artists’ pigments in Europe until the 19th century. For the first time, this work explores the technology of preparing weld lake pigments in the 19th century by Winsor & Newton (W&N), a renowned supplier of artists’ materials. Five recipes were discovered in the W&N 19th century Archive Database and reconstructed in the laboratory. W&N was extracting weld in neutral and basic media, and preparing the insoluble lake by complexation with Al3+ in the form of alum (KAl(SO4)2•12H2O) or hydrated alumina (Al(OH)3). Five yellow lake pigments were successfully obtained and characterized by High-Performance Liquid Chromatography-Diode Array Detector (HPLC-DAD) and Fourier Transform Infrared Spectroscopy (FTIR). Their chromatographic profiles display as main yellows, luteolin 7-O-glucoside (Lut-7-O-glu) or both Lut-7-O-glu plus luteolin 3′,7-O-glucoside (Lut-3’,7-O-glu). In two of the processes, the presence of gypsum (CaSO4•2H2O) was unequivocally detected by FTIR, being formed as a by-product. This work offers the first identification of weld lake pigments’ characteristic infrared bands. The W&N Database proved again to be a unique source of information on 19th-century artists’ materials and their commercial preparation. The knowledge gain is essential to ensure effective conservation and authentication procedures.

The 19Th Century

AbstractThe Habsburg Empire was a sovereign dynasty ruled by the Habsburgs between the 15th and 20th centuries. Although its borders were not defined before the 19th century, what is now Austria, Hungary, some areas of the Czech Republic, the Netherlands and Italy were at some point part of the Empire. Starting in the 17th century, the Empire had Vienna as the capital, which was a hub for culture and craft where silk was a valued commodity. Despite the political and cultural importance of the Empire, little is known of its trade practices and sources of raw material. Using a combination of X-Ray Fluorescence (XRF) and High Performance Liquid Chromatography-Photodiode Array Detector (HPLC-PDA) for the study of a Viennese swatch book, we conducted the first systematic approach to understanding the industry. Benedict Codecasa, a prominent merchant active in Vienna between the late 18th and early 19th century sold silk and other textile goods. Authorized by the Royal Court, Codecasa was assumed to sell luxurious and high-quality textiles. However, our results suggested colored goods were dyed with more focus on aesthetics (finding a similar color) rather than quality through unique recipes. This greatly contrasts with other contemporary textile industries praised for their quality and which, in turn, might be related to comparatively lesser quality textiles sold in Vienna.

This is a comprehensive, illustrated catalogue of the 200+ marine chronometers in the collections of Royal Museums Greenwich. Every chronometer has been completely dismantled, studied and recorded, and illustrations include especially commissioned line drawings as well as photographs. The collection is also used to illustrate a newly researched and up-to-date chapter describing the history of the marine chronometer, so the book is much more than simply a catalogue. The history chapter naturally includes the story of John Harrison’s pioneering work in creating the first practical marine timekeepers, all four of which are included in the catalogue, newly photographed and described in minute detail for the first time. In fact full technical and historical data are provided for all of the marine chronometers in the collection, to an extent never before attempted, including biographical details of every maker represented. A chapter describes how the 19th century English chronometer was manufactured, and another provides comprehensive and logically arranged information on how to assess and date a given marine chronometer, something collectors and dealers find particularly difficult. For further help in identification of chronometers, appendices include a pictorial record of the number punches used by specific makers to number their movements, and the maker’s punches used by the rough movement makers. There is also a close-up pictorial guide to the various compensation balances used in chronometers in the collection, a technical Glossary of terms used in the catalogue text and a concordance of the various inventory numbers used in the collection over the years.

The revised catalogue of primatological material stored in the Museo Regionale di Scienze Naturali of Torino and in the Dipartimento di Scienze della Vita e Biologia dei Sistemi of the Università degli Studi di Torino and belonging to the historical material of the Torino University is introduced. The material, 494 specimens belonging to 399 individuals of 122 taxa, is of particular importance since specimens were mainly obtained during the 19th Century and the beginning of the 20th Century. A relevant part of the collection was created by the collaborators of the Museum, among which it is worth to mention F. De Filippi, A. Borelli and E. Festa, while other material came from purchases and donations from private people or the Royal Zoological Garden of Torino. Great part of the specimens is stuffed but also the osteological materials are of particular importance, as many of them derived from the specimens before being prepared and consisting of skulls or more or less complete skeletons. After this revision, the Lectotype and Paralectotypes of <em>Alouatta</em> <em>palliata</em> <em>aequatorialis</em> have been selected, and the type-specimen of the <em>brunnea</em> variety of <em>Cebus</em> <em>albifrons</em> <em>cuscinus</em> has been recognized. In addition, some specimens of particular historical-scientific importance have also been identified and here presented for the first time.

The windmill. The origins of a Dutch icon The windmill is an icon of the Netherlands. But when did this instrument acquire this symbolic role at home and abroad? After all, mills are also common outside of the Netherlands. In this essay, it is argued that during the second half of the 19th century, foreigners systematically identified the Netherlands and the windmill for the first time. More than in other countries, there was a varied use of mills in the Netherlands, large and robust mills and clusters of industrial mills. Within the Netherlands itself, development towards an iconic position is only visible around the turn of the century when the mill turned out to be a plus in tourist recruitment abroad and when mills were slowly disappearing from the landscape.

The article analyses the process involved in the formation of the idea to separate the "Slovenian" and "Croatian" national territory in the west of the Kingdom of Hungary. The concept was initially articulated as a linguistic premise in the works written by the famous linguist Jernej Kopitar, who understood the territory of the today's Prekmurje region as an area where Slovenian language was spoken. As of the middle of the 19th century, Kopitar's classification had been appropriated by the Slovenian national movement, which presupposed that the speakers of the Slovenian language in the Kingdom of Hungary were also members of the envisioned Slovenian community. In this context the Slovenian linguistic – national border was, in the middle of the 19th century, depicted on a map for the first time (Peter Kozler). In just a few decades, the idea of the national demarcation line in the today's Prekmurje, supposedly separating Slovenians from Croats at the river Mura, had strengthened considerably among the Slovenian national activists in the Cisleithanian lands. After the dissolution of Austro-Hungary and the signing of the Treaty of Trianion, this line in fact became a border between the Slovenian and the neighbouring Croatian national space.

The article for the first time analyses the decoration parts of the Christ’s tomb of the second halfof the 18th century found a few years ago in Švėkšna church. The Christ’s tomb from the oldchurch was transferred to the  new church, which was built in 1804 and used until the  4thdecade of the 19th century. On the basis of the sources and remained fragments we can statethat this was a complicated structure of the Paschal decoration designed under the Europeanbaroque scenery principles. It was composed of the paintings on boards and canvas and mis-cellaneous accessories. The  Christ’s tomb paintings are characterised by a  symbolic allegoriccontent and artistry. The prophets of the Old Testament and characters the New Testamentreflecting the Paschal Triduum liturgy were depicted in the decoration. The survived outlinepaintings of Adam and Eve in Paradise, Noah waiting for the Saviour, and Angels Lamentingover the Death of Jesus are the exceptional iconography images in the Lithuanian church art.The decorations of the Christ’s tomb were created by the professional masters who decoratedthe churches in Samogitia in the second part of the 18th century. The images of suffering anddead Jesus used in the figuration of the Paschal Triduum influenced the spread of the Passionscenes. This is supported by an interesting archival fact about the shrine with a group of sculp-tures depicting the tomb of Christ in the Švėkšna churchyard.The fragments of the Paschal decorations in the Švėkšna church are important baroque scen-ery exhibits, which are valuable for the history of the Lithuanian church art and scenography.The investigation of the Holy Week figuration in the Švėkšna church is a valuable illustrationof this multidimensional cultural, religious and artistic phenomenon.

The article addresses the early years of film in iceland, where the goal is to deepen our knowledge of the main participants in introducing and promoting cinema in iceland at the turn of the 19th century. Two years spanning a three-year period mark the beginnings of the age of film in iceland. The former is 1901 when the Dutch filmmaker F. A. Nöggerath came to film iceland and icelanders for an English film company. The latter year is 1903, when the Norwegian, Rasmus Hallseth and the Swede David Fernander, traveled around the country to screen films for the first time in iceland. These two visits mark the emergence of cinema in iceland. iceland-ers had little prior knowledge of the new medium, which was getting to be widely known around the world, apart from the coverage of newspapers and stories of lucky icelanders who had experienced film screenings abroad. Shows using a predecessor of film, the magic lantern, were held by Sigfús Eymundsson and Þorlákur ó. Jo-hnson in the 19th century. After the introduction of films in 1903, several people put together funds to buy Hallseth’s and Fernanders’ equipment and began to exhibit films on their own. However, daily performances did not happen until Reykjavik Biograftheater (later ,,Gamla Bíó”) was established in 1906. After several attempts by various parties to hold regular screenings in Reykjavik, one could say that cinema did not properly settle in iceland until the establishment of Nýja Bíó in 1913.

Hydroxybenzyl Alcohol

Gastrodin (GAS) and its aglycone, p-hydroxybenzyl alcohol (HBA), are both bioactive compounds extracted from Gastrodia elata Blume (GEB). In the current Chinese pharmacopoeia, they are regarded as quality control markers for GEB. In this study, we developed a high-performance liquid chromatography method coupled with a diode array detector to quantify GAS and HBA concentrations in plasma following oral ingestion by rats. For the first time, GAS was detected in vivo after HBA administration. GAS and HBA both had similar pharmacological effects, but the influence of the glucose moiety resulted in different pharmacokinetic characteristics. In this study, the effects of GAS and HBA at different administration durations were investigated in zebrafish larvae. These compounds were found to induce a sedative effect but had different onset times. In conclusion, a biotransformation of HBA to GAS could be observed in the rats. This may be a new insight into the pharmacokinetic characteristics of these bioactive compounds and also relates to the different ways in which they take effect.

In this publication, the author conducts a specific historical reconstruction of the customary law ideas of the Don Cossacks about the responsibility of the perpetrators of the offenses committed by them in the second half of the XIX century in order to establish what actually, despite the ethnic identity and features of bringing these persons to various types of punishment under customary law, was the basis for the occurrence of a particular type of responsibility and constituted its essence. For the first time, the author proposes to consider of thecustomary representations of the Don Cossacks about responsibility for offenses through the concept of abuse of their duties (obligations) to the Don Cossack communities by all, without exception, members of communities and in various spheres of their life.

During the course of the second half of the 19th century, the rules regulating the conduct of armies during hostilities were internationally codified for the first time. The conventional narrative attributes the codification of the laws of war to the campaign of civil society, especially that of the founders of the Red Cross—Henry Dunant and Gustav Moynier. In what follows, we problematize this narrative and trace the construction of this knowledge. We explore how the leading figures of the Red Cross, who were aware of the shortcomings of their project, were nonetheless invested in narrating its history as a history of success. Their struggle to control the narrative would eventually confer the International Committee of the Red Cross (ICRC) with considerable interpretive and agenda-setting authority in the realm of the laws of war. We dwell on the meaning of this conscious exercise in knowledge production and its normative ramifications.
