Khan, M.A., Babar, M.A., Akhtar, M., Iliopoulos, G., Rakha, A. & Noor, T., November 2015. Gazella (Bovidae, Ruminantia) remains from the Siwalik Group of Pakistan. Alcheringa 40, xxx–xxx. ISSN 0311-5518.

New gazelle fossils are described from the Siwalik Group of Pakistan. The material includes horncores, maxilla and mandible fragments, and isolated teeth. The available samples are assigned to three Gazella species: Gazella sp. in the Lower Siwalik Subgroup (ca 14.2–11.2 Ma), and G. lydekkeri and G. superba in the Middle Siwalik Subgroup (ca 10.2–3.4 Ma). Based on a review of the Siwalik Group gazelles, G. padriensis is synonymized with G. lydekkeri. Gazella superba Pilgrim, 1939 sensu stricto is a large form and is a valid species of the genus in the Siwalik Group.

This article is a reconsideration of the Epistulae Austrasicae. We critique the widespread notion that the constituent letters were compiled by a courtier in the late sixth century at Metz as a book of models for use in the Austrasian chancellery. We argue instead that a monk from the monastery of Lorsch assembled the letters in the early ninth century from individual exemplars and groupings that he found in archives at Trier. We conclude by outlining some implications of this rereading for the edition and interpretation of the letters as sources for the Merovingian period, and point out some avenues for future research on their reception in the Carolingian period.  相似文献

In his influential account of the political history of early colonial Australia, Michael Roe identified the temperance movement of the 1830s–1840s as a pivotal factor in the secularisation of Australian culture and institutions. The belief system that drove the movement, he argued, was not traditional Christian doctrine but a “new faith” of “moral enlightenment.” In this article I test the validity of Roe's claim, drawing on the work of a more recent generation of historians and sociologists who have argued for more “porous” and “reciprocal” accounts of concepts such as reason, religion, the Enlightenment, and the secular. Its focus is on the writings and activities of John Saunders, whose endeavours on behalf of the temperance cause were such that he was described by his contemporaries as the “life and soul” of the society, the “father” of the movement, and the “apostle of temperance.” It examines the role played by key Enlightenment motifs such as improvement, optimism, reason and cooperation within the rhetoric of Saunders's writings and the reasoning that informed his actions, exploring the various and complicated ways in which he articulated the relationship between evangelical religious conviction and the quest for the common good.  相似文献

The accompanying articles that speculate that Alexander the Great had a traumatic carotid dissection or congenital cervical scoliosis demonstrate the difficulties in retrospective diagnosis as a historical enterprise. The extant primary sources were written centuries after Alexander's death and are ambiguous in their original languages, and even more so in translation. Thus we cannot be certain what illness Alexander actually had. Furthermore, anachronistic diagnosis removes Alexander from the medical context of this time, telling us little of historical significance about him. Such investigations also illustrate the more general limits that the absence of context imposes on the study of ancient history.  相似文献
