Page "Battle of Swally" Paragraph 6

Jan Huyghens van Linschoten ( 1563 – 1611 ) was a Dutch Protestant traveller and historian who also served as the Portuguese Viceroy's secretary in Goa between 1583 and 1588.

He returned to Holland in 1592.

He published a book, Itinerario in 1596 ( later published as an English edition as Discours of Voyages into Y East & West Indies ) which graphically displayed for the first time in Europe, detailed maps of voyages to the East Indies, particularly India.

During his stay in Goa, abusing the trust put in him by the Viceroy, Jan Huyghens meticulously copied the top-secret charts page-by-page.

Even more crucially, Jan Huyghens provided nautical data like currents, deeps, islands and sandbanks, which was absolutely vital for safe navigation, along with coastal depictions to guide the way.
