This essay argues that Bernini orchestrated the relief surfaces of his sculptures through an exacting science of optical perception. It connects his understanding of the relief structure of his sculptural work to Galileo’s contemporaneous discovery of the cratered surface of the moon to contend that art and science shared similar concerns in the visual analysis of relief perceived as patterns of light and shadow. Through a full contextualisation of one of Bernini’s many workshop aphorisms, about a man who whitened his face, it demonstrates the scientific, art-theoretical, and practice-based considerations that informed Bernini’s understanding of optics in the sculptural rendering of facial likeness through the medium of white marble.  相似文献

Arthur C. Clarke’s 1946 essay on ‘The Challenge of the Spaceship’ was one of the founding manifestoes of the Space Age, and helped to establish him as the West’s leading techno-prophet. Restating his ideas in subsequent factual and fictional works, Clarke successfully propagated the belief that man’s destiny lay in space and that the process was already underway. On the surface Clarke’s oeuvre offers a classic astrofuturist model of progress as technology-driven, but on closer examination it also incorporates a more pessimistic, historically based strand of philosophy, British rather than American. This essay traces the genesis of Clarke’s early work and the influence upon him of the historian Arnold J. Toynbee and the moral philosophers Olaf Stapledon and C.S. Lewis. Toynbee was essentially a Christian pessimist who believed that western civilization was on the way out; his long historical perspectives were an important source of inspiration for Clarke, leading him to a cyclical rather than a simply progressive model of history which contemplated both the beginning and the end of civilizations. The concerns of Stapledon and Lewis with grand narratives of decline and redemption were also influences on Clarke. All this needs to be understood in relation to both the European experience of World War I and to the coming of the atomic bomb, the latter a profound influence on Clarke’s generation. Such perspectives gave European astroculture a more modulated vision of the human future in space than the technologically based astrofuturism which dominated in the USA.  相似文献

When the British Admiralty announced in January, 1854 that it intended to strike the names of the officers of Sir John Franklin's missing polar expedition off the active Navy List, it had years of legal precedent to support its right to do so. The Board used such precedent to its advantage in ending a search its members had considered fruitless since 1849, the year the expedition's food would have run out. However, in their treatment of the widows made from that decision, Board members consistently pushed against established practice in order to do what they felt was right: to give the widows as generous a pension as the Treasury would approve, and to do so in defiance of the strict rules of eligibility. In 1844, only months before Franklin and 128 men set forth to discover the Northwest Passage, new eligibility guidelines were set that both limited women's access to pensions, and hampered the Board's ability to grant them. Archival evidence that forms the core of this article shows, however, that compassionate treatment of the expedition's widows was central to all discussions of how the Admiralty might move forward on the Franklin disaster, between promoting officers in absentia in order to augment pensions, to waiving the need for proving the date of death in order for families to collect the explorers’ back pay. As this article argues, the 1854 Admiralty Board had powerfully split loyalties: on the one hand, as the press acknowledged, the Board had a duty to perform on behalf of the public, to avoid wasting the nation's money on frivolous or useless searches for men assumed to be long dead; on the other hand, it felt equally strongly the obligation to support those widows who were the product of such imperial adventuring, even in defiance of its own rules. Through an analysis of legal precedent, Naval Instructions, and private Admiralty Board documents, in the case of the Franklin expedition's widows one can perceive a few naval administrators who tried to keep some of the nation's most vulnerable citizens in view even as they managed the bottom line.  相似文献
