Winckelmann in the perspective of Altertumswissenschaft: Christian Gottlob Heyne and Friedrich August Wolf

Winckelmann's writings hold an interest for modern classical studies which is not restricted to the subfield of classical archaeology. Considered in terms of methodology, his writings dramatise problems and questions which attend any attempt to provide a comprehensive account of ancient culture and society. The Geschichte der Kunst des Alterthums provided an influential model of what such a reconstruction might look like in a period when classical philology was undergoing a significant reconfiguration as „Alterthums-Wissenschaft" at the hands of scholars such as Christian Gottlob Heyne and Friedrich August Wolf. Investigation of their critical responses to Winckelmann’s works aims to contribute to understanding both of the early reception of his works and of questions which are still relevant today. Im Rahmen der modernen Altertumswissenschaften kommt den Werken Winckelmanns eine Bedeutung zu, die nicht auf den Bereich der Klassischen Archäologie beschränkt ist. Methodologisch betrachtet, dramatisieren seine Schriften Probleme und Fragen, die jedem Versuch einer umfassenden, erklärenden Rekonstruktion der antiken Kultur und Gesellschaft zugrunde liegen. Die Geschichte der Kunst des Alterthums hat ein einflussreiches Modell dafür geliefert, was eine solche Rekonstruktion in einer Zeit leisten konnte, in der die klassische Philologie einer erheblichen Umstrukturierung als „Alterthums-Wissenschaft“ durch Gelehrte wie Christian Gottlob Heyne und Friedrich August Wolf unterzogen wurde. Die vorliegende Untersuchung ihrer kritischen Reaktionen auf Winckelmanns Schriften soll dazu beitragen, sowohl die frühe Rezeption seines Werkes als auch Fragestellungen, die heute noch aktuell sind, besser zu verstehen.

Carl Maria von Weber’s Overture to Oberon: A History of Recorded Performance

My research examines the recorded performance history of the Overture to Weber’s Oberon in light of these aesthetic goals. I have charted changes in performance practice trends, including in timing, tempo fluctuation, rhythmic accuracy and ensemble, and the use of portamento. The twenty recordings studied that I surveyed span nearly seventy-five years, and include many of the 20th century’s most prominent conductors and orchestras, including groups from Communist Russia, both pre-World War II and post-World War II continental Europe, the British Isles, and the United States.8 Though by no means comprehensive, my selections encompass a diverse sampling of surviving recordings, ensuring a large enough sample size to reflect general trends in the performance of Weber’s masterpiece. My research and analysis confirms the conventional view of a move toward more accurate—but also more cautious, uniform, and inexpressive— performances. Surprisingly, however, this analysis also suggests that we are on the cusp of a new era in orchestra performance practice, one that shares many of the values of the earlier recorded performances. While maintaining today’s high standards of execution, modern performances now look to regain many of the past’s expressive qualities, doing so in sometimes surprising ways.

Análise de marcas de crescimento ósseo e estimativas de idade para Chelonia mydas (Linnaeus, 1758) no litoral do Rio Grande do Sul

A tartaruga-verde, Chelonia mydas, possui ampla distribuição geográfica circuntropical, ocorrendo em toda zona costeira brasileira. A espécie está incluída em diversas listas de animais ameaçados de extinção, sendo assim fundamental a elaboração de modelos demográficos que possam vir a subsidiar futuros planos de manejo. Contudo, muitos aspectos referentes à história de vida destes animais ainda são pouco conhecidos, por serem animais marinhos de difícil observação, especialmente durante o período que despendem nas áreas de alimentação e durante as grandes migrações. As tartarugas marinhas apresentam características, em seu ciclo de vida, que dificultam a realização de estudos de marcação e recaptura, para determinação de parâmetros importantes como crescimento e determinação de idade. Por esta razão, muitos estudos envolvendo determinação de idade utilizando linhas cíclicas de crescimento presentes nos tecidos rígidos - esqueletocronologia, vêm sendo acumulados para esta espécie. Muito pouco se sabe sobre quaisquer aspectos relacionados às etapas do ciclo de vida das tartarugas marinhas que habitam o litoral do Rio Grande do Sul, deste modo, este estudo tem como principal objetivo avaliar a técnica histológica utilizada usualmente nas análises de esqueletocronologia em tartarugas marinhas a fim de verificar a ocorrência de crescimento cíclico nos ossos e de se obter estimativas de idade para a população local. As amostras são provenientes de tartarugas-verdes encalhadas no litoral norte do Rio Grande do Sul e coletadas, de forma sistemática entre Torres e Mostardas, de março de 1994 a setembro de 2003. Os 89 exemplares (35%) de tartarugas-verdes registrados indicam que a espécie é a segunda em número de ocorrências, sendo menos freqüente apenas que Caretta caretta (54%). Foi verificada apenas a ocorrência de exemplares juvenis (ccc = 29,0 a 52,0 cm, média = 38,9cm), que estão iniciando o período de desenvolvimento costeiro. A técnica avaliada não apresentou os resultados esperados, necessitando de algumas modificações metodológicas. A partir da observação dos cortes histológicos pôde-se constatar a presença de linhas de crescimento ósseo em apenas onze dos vinte e quatro indivíduos que apresentaram resultados satisfatórios na preparação histológica, indicando que a deposição das linhas pode ser variável e dependente de fatores ambientais. Nos onze indivíduos puderam ser distinguidas de uma a cinco linhas de crescimento, indicando uma idade entre 1 e 5 anos para o término da fase no ambiente pelágico. Com estes resultados obteve-se o primeiro registro da presença de linhas de crescimento ósseo, assim como, a primeira estimativa de idade para a população de Chelonia mydas no início de sua fase de desenvolvimento costeiro no Brasil.

Teixeira de Freitas leitor de Savigny

The international circulation and reception of the works of Friedrich Carl von Savigny (1779-1861) constitute one of the main features of the first globalization of legal thought. Reaching law professors and practitioners from Brazil to Japan, readings of Savigny’s books offer a promising perspective for understanding how legal cultures around the world coped with the challenges of modernity. By focusing empirically on the circulation of books and analytically on the adaptation of texts to local contexts, the approach forwarded here tries to capture the creative aspects of the diffusion of knowledge. For this purpose, it concentrates on Brazilian readers of Savigny in the 19th Century, especially on the celebrated lawyer Augusto Teixeira de Freitas (1816-1883). It argues that Savigny’s works provided a decisive argumentative framework for some of the main issues discussed in Brazilian jurisprudence of the time. Freitas’ work documents a productive reading of Savigny that shaped his views on both normative and methodological issues, from slavery to codification. By tracing Freitas’ selective appropriation of Savigny’s texts, the article concludes that he was able both to reproduce and to subvert Savigny’s conception of private law, whenever the local context and his personal convictions demanded him to.

Histopathology findings in common marmosets (Callithrix jacchus Linnaeus, 1758) with chronic weight loss associated with bile tract obstruction by infestation with Platynosomum (Loos, 1907)

Chronic weight loss in marmosets is often associated with wasting marmoset syndrome (WMS), an important disease that occurs in callitrichid colonies around the world. Even though its etiology is very difficult to determine, particular variables, such as weight loss, diarrhea and alopecia, associated or not with infestation in the pancreatic ducts with Trichospirura leptossoma (Nematoda: Thelazioidea), seem to be linked with the syndrome. This study investigated the histopathology of the lungs, duodenum, liver, gallbladder, extrahepatic bile ducts and pancreatic ducts of six common marmosets (Callithrix jacchus) suffering from severe non-diarrheic weight loss. Three individuals died naturally and the other three were euthanized. Microscopic findings showed the presence of adult flukes (Platynosomum) in the liver. These flukes, which provoke common infection in cats, were also observed inside the gallbladder as well as in the intra and extrahepatic bile ducts in common marmosets. Portal fibrosis was observed in two animals, which developed chronic fibrosing hepatopathy (biliary pattern, grade 3). The disease progresses without diarrhea and without pancreatic lesions or infestation. With the rogression, the animals presented with ascending cholangitis, cholestasis and portal fibrosis, sometimes culminating in secondary biliary cirrhosis. Therefore, this nfirmity, associated with chronic weight loss in common marmosets, could be another tiological factor linked with WMS
