The value of empire: tenth-century Bulgaria between Magyars,Pechenegs and Byzantium

The article seeks to explain the connection between the migration of the Magyars and Pechenegs in central and south-east Europe, in the late ninth and early tenth century, and the conflict between Byzantium and Bulgaria during the same period. Through reference to anthropologists discussing the relations between nomadic and sedentary societies (Khazanov, Barfield), and historians studying medieval rituals (Buc, Althoff, Koziol), the article interprets the aggressive policy of the Bulgarian tsar Symeon as a consistent effort to displace Byzantium as major partner of the nomadic polities in the area. By subverting the principles of Byzantine diplomacy and political culture, Symeon turned his own kingdom into a society-structuring factor in the nomadic world. The article evaluates the very meaning of imperial claims not so much in legal terms, as an effort to guarantee Bulgaria’s sovereignty in a Byzantium-centred world, but in the real-time capacity of a ruler to make use of imperial symbols and act upon the dynamically changing conjuncture.     

Spain and the Partition Treaties (1697–1700)

This study takes an analytical approach to the diplomatic strategy adopted by the Spanish monarchy in confronting the challenge it faced associated with the Partition Treaties that were signed by Louis XIV, William III and the United Provinces in 1698 and 1700. By consulting Spanish sources to complete the understanding of the diplomatic process, this study analyses the political action that Spain mobilized in its defence around 1700 and describes the evolution of Spain's foreign policy as the product of the mistrust that had developed between the main powers of Europe. This mistrust was politically answered by Madrid with Carlos II's last will and other planned measures to ensure the viability of the project that contained a turning point in the policy underlying the alliances of the monarchy. Although, like that of the other powers, Spain's manoeuvrability was restricted, this study concludes that Spain was able to create policy action plans and rationally implement them; moreover, the dynamics resulting from the negotiation and signing of the Partition Treaties led the monarchy to oppose them at all costs and naturally led to the choice of a French heir as its only solution.     

A Social History of Trans-Imperial Diplomacy in a Crisis Context: Herbert von Rathkeal's Circles of Belonging in Pera, 1779–1802

ABSTRACT

This article explores the multiple circles of diplomatic agents and their social belonging in the context of the international crisis in late eighteenth-century Istanbul, drawing upon the private papers of the imperial internuncio at Pera between 1779 and 1802. The son of an Irish Jacobite supporter who became a Jesuit and then a radical reformer in Vienna, Peter Herbert von Rathkeal was also a member of the Pera society in which he was born and raised. An agent of one of the most influential trans-imperial households established in Friuli, and a member of the Austrian and British nobilities, Herbert sought to become an eminent actor of the Ottoman diplomatic scene while remaining the patron of a cosmopolitan commercial-cum-political clientele. To study Herbert's actions is to question the model of diplomatie de type ancien in a cross-cultural and fast-changing context of crisis. Despite the collapse of the old diplomatic order with the breakdown of the French Revolution, and despite rising tensions generated by the increasingly sensitive ‘Eastern Question’, this article reveals how Herbert von Rathkeal managed to maintain a certain stability in Istanbul due to the economic and social resources, which his different circles of belonging opened up for him.     

The development and evolution of “cerebral thermometry”: The physiology underlying a nineteenth-century approach to cerebral localization and neurological diagnosis

ABSTRACT

Surface thermometers were developed in the latter half of the nineteenth century. From the 1850s through the 1880s, collaborations between physicians, research scientists, and instrument makers produced clear improvements in the technology to measure cranial surface temperatures, with development of self-registering mercury surface thermometers resistant to pressure and little influenced by ambient temperature, apparatus for recording cranial surface temperatures from multiple stations simultaneously, and development of thermoelectric apparatus. Physiologic studies of cranial surface thermometry were conducted over a quarter century from 1861 to 1886. Beginning in the 1860s Albers in Bonn, Germany, and Lombard at Harvard and later in England systematically investigated surface temperatures on the head using surface thermometers and thermoelectric apparatus; they demonstrated that head temperatures were variable over time and across individuals and were not clearly influenced by thinking or muscular contraction but were influenced by ambient air temperature. In 1880 Amidon in the United States claimed that cranial surface thermometry during exertion produced localized increases in surface temperature on the contralateral scalp in a specific pattern (“external motive areas”) indicating underlying brain areas responsible for each movement. Amidon’s results were not reproduced by experienced physiologists in England or France. Contemporaries recognized that significant technical and practical problems limited the accuracy and reliability of cranial surface thermometry. Physiological studies of cranial surface thermometry ended in the mid 1880s, although some clinicians who were early advocates promoted its use in clinical contexts into the early twentieth century.     

Natural and supernatural virtues in the thirteenth century: the case of Marguerite Porete’s Mirror of Simple Souls

This article argues that Marguerite Porete’s seemingly unorthodox presentation of the virtues in the Mirror of Simple Souls is not a critique of scholastic learning, but in fact reflects the thirteenth-century university discourse on this topic. The rediscovery of Aristotelian thought in this period led to the redefinition of the standard Augustinian definition of virtue as being divinely infused. Philip the Chancellor’s discussion of cardinal virtues in particular prompted thinkers to distinguish between natural and supernatural virtues. It is contended that the Soul’s abandonment of the virtues should not be read as a rejection of the virtues, but rather as the affirmation that only supernatural virtues lead to God. A consideration of how Godfrey of Fontaines, theologian and reader of the Mirror, understands the virtues confirms the basic orthodoxy of Marguerite Porete’s position, lending further support to the argument that the Mirror echoes sophisticated scholastic ideas.
