1. As analogous to the triumphant entry of Napoleon into Egypt in the early nineteenth century, accompanied by swarms of "experts" on ancient Egyptian culture; Napoleon's extraction of Egyptian monumental remains, installed in the cityscapes of museums of Europe, represent the view of "the East" as both object of Western triumph and source of Western knowledge. So, too, the "eastern" manuscripts of Bibles extracted by Bible hunters.
2. As analogous to the missionary trips flowing from the Protestant United Kingdom throughout the Victorian era, certainly enabled by the institutional apparatus of British colonialism, but impelled by the idea that the entire world could be made Christian and, in turn, give proof to the truth of Christianity over all other religions.
The Bibles that come to light (and even that locution suggests that they were somehow mired in darkness before being viewed by Western eyes) are at once the eastern spoils of the West and the providential proof of Christian truth. Both attitudes are unsurprisingly triumphalist, but also surprisingly fragile. To extract Western truth from the "foreign" territory of the East is to ask how Western that truth really is and how true it is, after centuries kept in the hands of others. This hope for new, triumphal truth coupled with anxiety about its durability and reliability shadow these Bible hunting endeavors, as well as Gospel Thrillers that come in their wake.
