Jan Huygen van Linschoten's chart of the coasts from the Red Sea and Arabia to the Bay of Bengal, from the Itinerario — the book that broke open the Portuguese monopoly on Eastern navigation. Among the first European maps to render India and Arabia with real accuracy, it is less a finished survey than a leaked working knowledge of how to sail to the Indies.
Authorship and object
Linschoten (1563–1611) spent years at Portuguese Goa as secretary to the archbishop, copying the closely guarded Portuguese roteiros — the sailing directions that were state secrets. Published in Dutch in 1595/96 with natural-history contributions from Bernard Paludanus, the Itinerario put this intelligence into print; this sheet is from the later French edition, the Histoire de la navigation.
Why it mattered
The coastlines of India and Arabia here were a marked advance on earlier printed maps because they rested on actual Portuguese navigational practice rather than on compilation. By making that knowledge public, Linschoten directly enabled the Dutch and English East India Companies — the chart is, in effect, the navigational key to a century of northern European expansion in Asia.
Content and style
Oriented to working navigation, the sheet spans the maritime arc from the Red Sea to Bengal, dense with coastal detail and embellished in the Dutch manner with ships, compass roses and sea creatures.
The gaze
This is the gaze of the rival pilot: India seen as a coastline to be reached, traded with and contested. Knowledge here is explicitly strategic — a stolen advantage converted into a printed instrument of commerce and, soon, of empire.
