This article presents and discusses a source of unique importance for our knowledge of early modern global exchanges. Produced in 1503 by the Egyptian administration and found among the records of a Venetian company with global commercial interests, the document records hitherto unknown connections between the Arabian Peninsula, the Indian Subcontinent and Southeast Asia, followed by cargo figures. By sending the Memorandum to the head office in Venice, the Company's agents in Egypt were labouring to solve the most important concern of Venice's information network, that of coordinating Indian with Mediterranean trading seasons. By analysing the document's context, namely, a company involved in the export of central European metals to Asia, this article focuses on the capacity of its agents to gather information through collaboration, networking and ultimately, friendship with Muslim partners and informers. The story of the 1503 Memorandum and its transmission raises questions about the mixed networks underpinning global exchanges, the role of information and the drive of the late Mamluk sultanate into the world of the Indian Ocean.

Drawing on a far-flung, multilingual archive of contracts and financial instruments from around the western Indian Ocean, this article highlights how cross-cultural trade depended on the ability of groups to translate between one system and another, rendering one commercial lexicon legible to another so as to produce commensurability and allow for conversions to take place. Law constituted a foundational building block of this process: Indian Ocean merchants drew on a deep well of legal concepts and forms as they attempted to make their worlds legible to one another, mobilizing the grammars of law to bridge commercial systems. We situate these dynamics within the context of the Indian Ocean ‘bazaar’, establishing it as a site for thinking about the place of cross-cultural trade in world history, and the histories of global capitalism more broadly. We suggest that Euro-American capitalism’s very agents had to adapt their commerce to the idioms, logics, and contracts of their business partners around the Indian Ocean – a vernacular world of the bazaar that was itself already in motion.
