Much of the literature on the Ancient Silk Road has examined its operation through the prism of empires and East-West connections. Yet in the last few decades several scholars have sought to re-examine this framework, with a number suggesting that the roots of the Silk Road exchange network should be sought instead in the many polities which lay along its routes. This article similarly seeks to challenge the traditional ‘Silk Road of Empires’ concept by applying approaches from global history and examining both archaeological and written sources from the third- and fourth-century kingdom of Kroraina in the south-eastern Tarim Basin in Xinjiang, Western China. The first goal of this article is to consider Kroraina’s inclusion in the wider Silk Roads network and how this network influenced local elite consumption. The second is to examine Kroraina’s role in the Silk Road network. It is argued that polities like Kroraina played a crucial role in facilitating and maintaining trans-Eurasian trade in Late Antiquity.

Nineteenth-century physicians increasingly favoured leeching – the placing of a live leech onto a patient’s skin to stimulate or limit blood flow – as a cure for numerous ailments. As conviction in their therapeutic properties spread, leech therapy dominated European medicine; France imported over fifty million leeches in one year. Demand soon outpaced supply, spawning a lucrative global trade. Over-collection and farming eventually destroyed leech habitats, wreaked environmental havoc and forced European merchants to seek new supply sources. Vast colonies of leeches were found to inhabit the immense wetlands of the Ottoman Empire, which soon became a major exporter of medicinal leeches. Following the Treaty of Balta Liman (1838), the Ottoman state moved to exert control over the lucrative trade, imposing a tax on leech gathering and contracting with tax-farmers (mültezim) to collect the taxes. British diplomats, merchants and other stakeholders protested the imposition of the tax, as had previously happened with the commodification of wildlife; their pursuit of profit led collectors and farmers to over-gather leeches, with catastrophic consequences. By the end of the century, so great had their worth climbed that the leech population faced extinction. This paper situates medicinal leeches as therapeutic actors of history and adopts an interscale approach in formulating the human-leech interaction. It offers a substantive contribution to the history of medicine, in revealing the centrality of leeches to the rise of modern medicine and global trade, but also by making visible their role in shaping imperial diplomacy and worldwide economic markets.

Markets allow for the processing of decentralized information through the price mechanism. But in addition, many markets rely on other mechanisms in markets, or non-market institutions, that provide and manage other forms of knowledge. Within national economies, these institutions form an ‘epistemic infrastructure’ for markets. In global markets, in contrast, this epistemic infrastructure is very patchy, undermining the preconditions for morally responsible agency. New technologies might help to improve the epistemic infrastructure of global markets, but they require conceptualizing knowledge not only as a tradable good, but also as a precondition of morally responsible agency.

Exotic natural objects brought to Europe in the sixteenth and seventeenth centuries were mutable and malleable things. They were constructed and assimilated into European world-views in a reciprocal process of change as they moved around early modern Europe. In particular, the provenance of natural objects and the associated rich symbolic resonances were central to their natural histories. The distinctions between Orient and Occident had divided the world since antiquity and were given a range of new senses in this period. The location of these two ‘Indies’, and their relationship to one another, were neither static nor always geographically defined. This article focuses on two rich examples of this natural historical construction in relation to images of the Indies: the Old World pangolin, or scaly anteater, and its New World counterpart, the armadillo. Initially, pangolins were understood as East Indian ‘scaly lizards’, armadillos as West Indian. But from the late seventeenth and early eighteenth centuries, their geographical identities and symbolic associations were entangled as these creatures came to embody colonial anxieties and resonances. The ‘India’ of the scaly lizard became the ‘Indies’ of the scaled mammals, both East and West. Examining the reception and treatment of examples such as these in European cabinets and natural histories, offers new insights into European relationships with regions of the world seen as distant and wonderfully bountiful.
