Company of East India Merchants

The Company of East India Merchants is presented as an institutional buyer of secret Portuguese navigational knowledge, not through a portrait of its operations but through the passage of valuable sailing directions into its hands. Its monopoly on Far Eastern exploration links commercial privilege to the control of routes at a time when safe ocean travel depended on scarce, guarded information.

Identity and Privilege

The Company appears in the account of Pieter Suyderhof, a Dutchman who served as private secretary to the Primate of Goa, the chief Catholic priest there. Documents passed through Suyderhof’s hands; over many years, he obtained Portuguese sailing directions and copied them. When he returned to Holland, he sold the copies to the Company of East India Merchants, which had been granted a monopoly for Far Eastern exploration.

The text does not describe the Company’s officers, internal structure, or voyages. Its importance is instead established by the privilege it held and the knowledge it purchased: a monopoly over exploration in a region whose routes were guarded as strategic national secrets.

The Rutter as a Strategic Resource

The material Suyderhof copied was more than a coastline map. A rutter recorded compass courses between ports and landmarks, soundings and seabed conditions, winds and currents, the timing of storms and fair weather, places to take on water or careen a ship, and the location of reefs, shoals, tides, havens, friends, and enemies. It gathered practical instructions for reaching a destination and making the return voyage.

Such books mattered because existing charts could be too vague to guide a voyage reliably, while navigators had no way to determine longitude. Portuguese and Spanish authorities guarded directions to the New World, the Strait of Magellan, the Cape of Good Hope, and the routes onward to Asia. Their English and Dutch rivals sought that knowledge with equal intensity. The Company’s purchase therefore places it within a wider struggle over access to maritime information, although the text does not say that it itself conducted any particular voyage using the copies.

Acquisition, Reliability, and Consequence

The transfer also exposes the uncertain quality of navigational knowledge. A rutter depended on the pilot who compiled it, the scribe who copied it, any printer who reproduced it, and any scholar who translated it. Errors could enter at every stage, and pilots might even insert them deliberately. A written route could guide a voyage, but it could not replace the experience of testing the waters in person.

Blackthorne identifies his own lost rutter as the Magellan route and explains that copies of such Portuguese directions had passed through Suyderhof to the Company. He considers the information vital to him and potentially valuable to Toranaga. The Company’s brief appearance thus gives the book’s knowledge economy a concrete institutional endpoint: guarded routes become saleable copies, and those copies may travel far beyond the European commercial contest that first made them valuable.
